Description

The present invention relates to a wearable apparatus, for use when throwing an item, including disclosure of where the item is retained in the wearable apparatus after the item is thrown. Disclosure is provided of wherein the item that is thrown is a ball. Terms / Definitions ‘Arrangement’: The term arrangement is a technical term which means a feature, or combination of features, (usually with a given purpose). For example, a 'measuring arrangement’ is a feature or features, to facilitate measuring. A 'holding arrangement’ is a feature or features, to facilitate holding. ‘Feature’: The term 'feature' is a broad term that includes within its scope any feature under the Sun. A feature may, for example, be an element, body, member, or may even be an aperture (eg opening / hole / gap or the such like). Thus the term 'holding feature’ includes within its scope, for example, any element, body, member, or even aperture, to facilitate holding. A ‘feature’ may also be a ‘part’ of a broader feature; for example, if a part of an invention is disclosed / claimed as comprising a 'padding feature’, this does not limit the padding feature to being a separate feature that is added to the invention (eg a sponge element, adhered to the invention); the invention, for example, may have a part made of sponge, or have an inner sponge (or soft) layer- in such a case, if that part of the invention is clearly of a material / nature that provides padding, then this falls within a scope of what is defined in the present application as a ‘padding feature’. ‘Substantially’: It is known, to those with skill in the art of patenting, that the word ‘substantially’ can, in some instances, be used to broaden a term. It should be stated that, in the present application, use of the word ‘substantially’ with a term, to define a (characterizing) feature(s), gets all the benefit (ie the benefit of any broadening) afforded by use of the word ‘substantially’, and also includes within its scope the feature(s) being that term exactly, (without broadening). For example, if two features are described / defined in the present application as being ‘substantially parallel’, then that includes, within its scope, the features being ‘close’ to parallel (in so far as the word ‘substantially’ is deemed to broaden the term 'parallel’), and also includes within its scope the features being 'exactly’ parallel). ‘Velcro®’ And ‘Velcro®-type’: It will be known that the term ‘Velcro®’ has become synonymous (in layman’s terms) for hook-and-hook, hook-and-loop, loop-and-loop, and all such similar attachment solutions. In the present application, where the term ‘Velcro®’ is used, in includes within its scope all of the above, and whatever solutions would be considered to be, from a layman’s point of view, ‘Velcro®’. Thus it is a broad term. The term Velcro®’, or Velcro®-type’, may be used, (in the disclosure generally, and may also be used in a claim(s)), and is thus a broad term which includes within its scope any solutions / features which would be considered, from a layman’s point of view, to be 'Velcro®'. The term 'hook-and-loop type attachment’ may also be used as a broad term and this term should be interpreted as broadly as the everyday laymen’s use of the term Velcro®’. Thus the term ‘hook-and-loop type attachment, (and the term 'hook-and-loop type’) is a broad term. (The term 'hook-and-loop type securing’ may be used. (The term 'hook-and-loop type securing element(s)’ may be used)). ‘Attached’ And ‘Connected’: If a feature (or two features) are defined in a claim as being attached, that would include within its scope the feature (or two features) being permanently attached, (of course), and would also include within its scope the feature (or two features) being removably attachable, (because, if removably attachable, the feature (or two features) can be attached, and therefore, when attached, would be within a scope of being 'attached’). Furthermore, the feature (or two features) being defined in a claim as being 'attached’ would also include within its scope the feature that is defined as being 'attached’ being formed as one part with a portion or a whole of the other feature it is defined as being ‘attached’ to. For example, if a table leg is defined in a claim as being ‘attached’ to a table top, that would include within its scope the table leg being formed as one part with a whole of the table top (eg if the table leg and table top were formed as one piece of plastic, for example) and would also include within its scope the table leg being formed as one part with a portion (rather than a whole) of the table top (eg if the table top was formed of more than one part, and the table leg was formed as one part with a part of the table top, but not a whole of it). (It would also include within its scope a portion (rather than a whole) of the feature that is defined as being ‘attached’ being formed as one part with a portion (or a whole) of the other feature it is defined as being ‘attached’ to. Thus if the table leg had a separate top half and bottom half, for example, (that are attached together, in use), an embodiment where the top half of the leg is formed as one part with a portion (or a whole) of the table top would also be within a scope of the table leg being ‘attached’ to the table top). It should be noted, some (few) patent offices require structural connection / relationship terms (in claims), to define structural connection / relationship between features of the claim. With this in mind, (and if it should be required, although it often is not), the term ‘connected’, if used in a claim, is a broad term, which includes within its scope direct connection, and also includes within its scope indirect connection. ('Direct’ connection would be where two features, for example, are directly connected to each other (eg an arm is ‘directly’ connected to a shoulder). 'Indirect’ connection would be where two features, for example, are connected, but via intermediate feature(s) (eg a person’s foot is ‘connected’ to their head, but 'indirectly’, (via their leg, torso, etc, which are 'intermediate features’)). Where the term ‘connected’ is used in a claim, it includes within its scope ‘direct’ connection, and also includes within its scope ‘indirect’ connection. The term may be used in a claim, (and is deemed supported), whether ‘direct’ and / or 'indirect' connection embodiment(s) is ( / are) disclosed in the present application, and, as stated, includes within its scope 'direct' connection, and also includes within its scope ‘indirect’ connection. Furthermore, if a feature(s) is ( / are) defined as being ‘connected’, that would include within its scope the (or any- ie more than one of the said) feature(s) being removably attachable, if, when attached, the feature(s) is ( / are) in a state of being 'connected’, (directly or indirectly). Thus if a first feature is defined as being 'connected’ to a second feature, it would include within its scope the first feature and / or the second feature being removably attachable, if, when attached, the first feature is connected to the second feature, (directly or indirectly). Furthermore, of course, (and similarly to the word 'attached’), if a feature (or two features) are defined in a claim as being 'connected’ it would also include within its scope the feature that is defined as being 'connected' being formed as one part with a portion or a whole of the other feature it is defined as being ‘connected’ to. (With reference to what has been stated relating to ‘direct’ and 'indirect' connection, so the same is the case for the term 'attached'. Thus if a feature(s) is / are defined as being 'attached' to another feature, that includes within its scope being 'directly' attached to that other feature and includes within its scope being 'indirectly' attached to that other feature. (Thus, if a feature(s) is / are defined as being 'removably attachable’ to another feature, that includes within its scope being removably attachable to that other feature ‘directly’ and includes within its scope being removably attachable to that other feature ‘indirectly’). (As stated with reference to the term ‘connected’, the term ‘attached’ may be used in a claim, (and is deemed supported), whether ‘direct and / or ‘indirect’ attachment embodiment(s) is ( / are) disclosed in the present application, and, as stated, includes within its scope being ‘directly’ attached, and also includes within its scope being ‘indirectly’ attached). ‘The Or Each’And ‘The Or Any’: The term 'the or each’ (either in disclosure and / or a claim) can refer back to a single feature / thing, and / or can refer back to a plurality of features / things. When the term is read as referring back to a plurality of features / things, it should be taken as meaning, and including within its scope, ‘at least one, or more, or all (ie each)’ of the said features / things. Thus, to give an example, if a square is referred to / disclosed that has four corners, if the term ‘the or each corner’ is used, it includes within its scope 'one of the corners, (or two, or three, or all of the corners)’. When any one feature / thing is afforded any feature(s) / definition in the present application, it is taken as read that, where a plurality of the said feature / thing is provided, 'the or each’ said feature / thing may be provided / claimed comprising the said feature(s) / definition (ie at least one, or more or all). Similarly, wherever a plurality of the said feature / thing are afforded any feature(s) / definition, it is taken as read that 'the or each’ said feature / thing may be provided / claimed comprising the feature(s) / definition (ie at least one, or more, or all of the plurality), and / or that even just one said feature / thing may be provided / claimed comprising the feature(s) / definition in an embodiment / claim wherein an invention is defined as comprising ‘a’ (eg singular) said feature / thing. (The term 'the or any’ may be used (again including within its scope, 'at least one, or more, or all (ie each)’, instead of the term ‘the or each’). ‘User Means’: It will be well known that, in certain patenting territories, (for example, the United States), use of the term 'means’ or 'means for’, if used in a (granted) patent claim, can be seen as a limiting term, limited to only giving the applicant / proprietor of the patent protection of means that are disclosed in the granted patent, or ‘equivalent’ means. This is not the case with the term ‘user means’ as it is used in the present application. The term 'user means’ is a very broad term that is used in the field of product design / user-interface, and defines any means under the sun, provided for a user, for whatever action / result the user means is provided for. For example- a 'user means’ to turn on a television could be provided by way of an ON / OFF button on the television. But it could also be provided by a button on a remote control which turns on the television when pressed. Both of these would fall (in the technical field of product design / user-interface) under the scope of the term 'user means’ to turn on the television. Similarly, with certain inventions / products, a ‘user means’ may be provided to ‘initiate’ an action, for example. Thus, in the present application, a claim that defines an invention which comprises a 'user means’ for [a particular action / result] is not subject to any 'means for’ limitations that certain patent office territories (such as the United States) may appropriate to the term ‘means for’, but should be read as (and given protection for, if granted) any means under the sun, provided for a user, for [that particular action / result defined], ‘User means’ is a technical term in the field of product design / user-interface. Reference To Multiple Similar Elements In Plural In the present application, there may be provided / numbered features wherein the same primary number is used, with a suffix. For example, a first side of the / an invention may be numbered 600’, and a second side of the / an invention numbered 600”. In any such case, (or where any other suffix is used, such as 1’ and ‘R’ to denote ‘left’ and ‘right’, or 'a' and ‘b’, for example), when such features are referred to together (Ie 'the sides’), the plural may be numbered / referred to with the primary number (without the suffix). Thus the first side 600’ (or 600a, for example) and second side 600” (or 600b, for example) may, for example, be referred to simply as 'the sides 600’. Furthermore, if a side is referred to (not specifying which one of the sides), the primary number (ie 600, for example) may be used, without any suffix. Background Many sports include the discipline of throwing a ball as part of the sport. These include, (but are not limited to), baseball, softball, cricket, and American Football. (Since the term 'football’ is used in most territories around the world for the originally UK-based sport of that name, the term ‘American Football’ will be used in this application for the sport that is referred to as ‘football’ in America and which involves / includes regular throwing of a ball (referred to in America as the ‘football’) by a quarter-back, for example). (There are also various derivatives and / or similar games to these that involve throwing a ball. For example, the sport ‘rounders’ is an example). Baseball, softball, and cricket and fairly important / relevant examples, and are similar in that they include two main types of throwing- a more ‘standard’ throwing, and a more ‘specialized’ throwing. In baseball, for example, there is a more ‘specialized’ type of throwing, called ‘pitching’, (which it is here made clear is considered to be within the scope of the broad term ‘throwing’), and a more standard type of throwing, (ie by just a person in the field (which may be referred to as a fielder), doing a more normal / standard throw). (Standard throwing can be done over-arm or under-arm, and it will be known to those with skill in the art of throwing (and / or knowledge of the relevant sport(s)), that standard throwing can be done with an action that looks mid-way between ‘over-arm’ and ‘under-arm’, and this technique is often used by high quality throwers since it can be a good way to throw quickly and with a lot of ball speed). In cricket, similarly, more ‘standard’ throwing is often done, (ie just a fielder either throwing the ball over-arm or under-arm, (and. Similarly to as mentioned in baseball, standard throwing can be done with an action that looks mid-way between ‘over-arm’ and ‘under-arm’), and a more ‘specialized’ type of throwing, called ‘bowling’. There are clear parallels between the sports in that, in both baseball and cricket, it is the more ‘specialized’ throwing, (ie pitching / bowling), that starts each ‘play’. Baseball and cricket may be mentioned significantly in this application. However, it is made clear, as stated, that many sports include the discipline of throwing a ball as part of the sport, and these are just two examples, in no way limiting the scope of any apparatus / method disclosed in the present application. Throwing can be useful / important in these sports, not just during actual play, but also in terms of training / practice. (In the present application, the term ‘training’ is considered to include within its scope the term ‘practice’). Thus if the term ‘training’ is used, it includes with its scope ‘practice’). Throwing can also be important in terms of sports therapy / rehabilitation for those injured in such a way that affects their throwing. Thus throwing can play a role in injury management and / or rehabilitation, (eg training biomechanical changes in throwing technique to prevent further injury). Thus throwing can be useful for training and / or rehabilitation pirposes. (Note: A specialist may teach such things, (ie whether just generally to do with throwing technique, or more specifically to do throwing technique with regard to injury management and / or rehabilitation). This is also considered to be within the scope of 'training'. (Thus the term 'teaching’ [someone], (in such things), for the sake of the present application, is considered to be within the scope of ‘training’ [someone], (in such things))). In summary, (put in broad terms), if can be desirable to throw a ball, even when not actually playing the sport. However, there are some obvious problems with this. For example, throwing a ball anywhere near full power / effort by the user can result in the ball being thrown a very long way. If there is no one to immediately gather the ball from where it finishes (or goes to, (eg being caught, for example), then it may or would be very time consuming to gather the ball(s) once thrown. (As part of this problem, it may be necessary to have many balls to throw, otherwise the thrower may spend more time gathering the ball(s) than actually throwing them). This also creates the problem that a wide expansive space will be needed (for long throwing). This will tend to mean only an outdoor space is appropriate. And if an indoor place was used, (especially if it was a space / environment not made for throwing in, eg just a normal house or room, for example), there would be a high risk of doing significant damage to the surrounding area, whether it be damage to the space / room itself and / or to items contained within the space / room. In fact, it may be inevitable that such damage would take place. And it could even do damage to the thrower (and any people in the place / space), eg due to the ball bouncing off a surface(s), (eg a wall(s)), and re-bounding and hitting someone. Attempts have been made to provide a solution to this. For example, SUPPAN (US2011 / 0172036 A1) discloses a 'baseball / softball training pouch’ that is 'adapted to be worn on the wrist of the throwing hand of a user’, and which has a 'dosed end’. Thus a ball that is thrown by the user is retained by the apparatus. However, there are inherent issues with such an apparatus. For example, being worn merely on the wrist is not a design that lends itself to being highly stable. It goes without saying that the apparatus sliding / slipping when worn is not desirable. It could significantly affect the thrower, (and the thrower’s technique). There have been attempts to solve this problem to some extent. For example, STOUFFER (US2020 / 0282280) teaches there being a "compression sleeve ... such that generally constant contact is formed with the user’s arm along a length of the compression sleeve”, and discloses that "The compression sleeve may extend to above the user’s elbow”. However, anyone who themselves is skilled in any sport that involves powerful, co-ordinated and complex movement of the arm, (either in order to throw a ball, or to hit a ball, for example), will know that 'compression’ of the arm is highly undesirable. Not only may it cause significant discomfort, it could even impede blood-flow, either creating simply 'numbness’ in the user, (which itself would be highly undesirable), or worse. Furthermore, when there is compression around a joint, (eg the elbow), this is particularly undesirable, and clearly could impede the thrower from being able to fully carry out their normal throwing technique, (or may even make it impossible to carry out their normal throwing technique). The act of powerful pitching / bowling or over-arm throwing includes all kinds of co-ordination and levers (of the arm and body) being used by the thrower, some of them unconsciously. The moment any limitation is put on movement of joints, tensing of muscles, etc, not only will it inevitably lead to annoyance and / or discomfort from the thrower, it may well make them either intentionally not throw the ball as powerfully and / or naturally as normal, or may make it impossible for them to throw the ball as powerfully and / or naturally. Worse still, because it may affect their form / technique, (and / or even just make them 'hold back’ a little), it could, ironically, even lead to far greater chance of injury, because this can result in abnormal musde / joint movements, (compared to normal (unimpeded) throwing). Thus it is highly, highly undesirable, (for many reasons), to have the throwers in any way hampered / affected by any apparatus that is worn by the user. (Compression even of muscles is also not at all desirable for not un-similar reasons). (ARNOLD (US20120052990) suffers from similar problems, teaching ‘A fastener is attached to the sleeve and adapted for compressive attachment of the sleeve to the arm”). It would be desirable if a wearable apparatus could be provided that retains a ball when thrown, and that is designed to cause as little hindrance to the arm as possible. (It would also be desirable if the apparatus provided some sort of feedback to gauge how well the ball was thrown). Summary An invention(s) is defined by the accompanying claims, to which reference should now be made. Examples of the present invention seek to provide a solution to any or all of the above problem(s) by providing, according to one aspect of what is invented: a method of retaining a ball after throwing the ball, comprising: a wearable apparatus being worn by a user, the wearable apparatus itself comprising: an arm portion, for a throwing arm of the user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user; the ball being held by the throwing arm of the user; the ball being thrown by the throwing arm of the user; and the ball being retained in the wearable apparatus after having been thrown by the user Preferably the securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to a torso of the user. Preferably the securing portion travels around a torso of the user, at the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso. Most preferably, the securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso of the user. (The user may also be referred to as the ‘wearer’). (Preferred embodiments will be shown and disclosed wherein the securing portion travels around a torso of the user, at the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and the securing portion also travels around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). The wearable apparatus travelling around the reverse side of the body of the user opens up all kinds of possibilities for ‘freeing up’ the throwing arm of the user, when throwing. (This is particularly relevant in various preferred embodiments, where the securing portion travels around both sides of the torso of the user, various embodiments of which will be explored). This opens up the possibility of hugely improving on, or completely eliminating, problems mentioned such as lack of stability, compression of the arm, (which could create discomfort and / or even impede blood-flow, and could even limit range of movement of joint(s)). The net result is that the user can throw the ball far more naturally, (with the intent being that the user can throw the ball completely naturally). Benefits to this can include any of the following- that the apparatus becomes a better practice / training tool since it allows the user to use their normal throwing technique; that the user is less likely to incur injury to self by using unnatural throwing form / technique, (which may itself make the apparatus more useful, in terms of use during rehabilitation from injury, for example); and that the user is able to throw with full power, unimpeded. Preferably, the method comprises using auditory feedback from sound of the ball impacting the hand end of the arm portion when thrown. This can be used to assess the throw. This can be useful for various reasons. For example, auditory feedback could be used to assess quality of the throw. (Like a 'sweet spot’ on a tennis racquet or ‘bat’ of any sort, for example, creates a particular sound, (or less of a sound), denoting, (at least to those with skill / understanding in such sports), that the ball has been struck with the 'sweet spot’, so a particular sound, (when the ball is thrown and impacts the hand end of the arm portion, internally), may denote a better quality throw. This can come as a result of the user 'timing’ the throw better, for example. It can denote a better ‘release’ of the ball, for example. With regard to another reason, for example, auditory feedback could be used to assess power of the throw. (A louder sound (when the ball is thrown and impacts the hand end of the arm portion, internally), can denote a more powerful throw, for example). (Structural definition / feature(s) to facilitate this will be explored). Preferably the arm portion is increasably and decreasably adjustable in length. (This can have several benefits, including, for example, the apparatus fitting users of different shapes / sizes). Preferably the securing portion is increasably and decreasably adjustable in tightness, around the user. (This may be particularly useful / beneficial for embodiments where the securing portion travels around both sides of the user, under each arm of the user, for example). (This can have several benefits, including, for example, the apparatus fitting users of different shapes / sizes). According to another aspect of what is invented, there is provided: a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user. According to another aspect of what is invented, there is provided: (a wearable apparatus for retaining a ball when throwing the ball, comprising:) an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion. (Note: According to this aspect of what is invented, the 'arm portion’ may be the whole of the apparatus. Thus the term ‘portion’, (with respect to the term ‘arm portion’), should not be seen as overly limiting, for example and should not be seen as meaning that there must be other 'portion(s)7’part(s)’). (According to this aspect of what is invented, the wearable apparatus may or may not comprise a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user). According to another aspect of what is invented, there is provided: a method, comprising: a wearable apparatus being worn by a user, the wearable apparatus itself comprising: an arm portion, for a throwing arm of the user, the arm portion being enclosed at a hand end of the arm portion to block a ball from exiting the arm portion when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user; the ball being held by the throwing arm of the user; the ball being thrown by the throwing arm of the user; and the ball being blocked from exiting the arm portion, when thrown, by virtue of the arm portion being enclosed at the hand end. (It is here made clear that, according to this aspect of what is invented, it is not required that the ball cannot escape after having been thrown by the user. For example, according to this aspect the ball may be able to escape- for example, (according to this aspect of what is invented), an embodiment(s) may be provided where there is space for the ball to escape. For example, (as will be explored), according to this aspect of what is invented, an embodiment could be provided where the user could point their arm upwards, and there may be space for the ball to simply 'fall out’ of the apparatus, for example. (However, according to this aspect of what is invented, preferably the wearable apparatus is operable in a mode wherein the ball cannot escape out of the wearable apparatus. (Guaranteeing that the ball cannot escape out of the wearable apparatus after having been thrown can be extremely beneficial)). (Thus, it should be stated, according to an aspect of what is invented, there is provided: a wearable apparatus, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to block a ball from exiting the arm portion when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user). (Thus, it should be stated, according to an aspect of what is invented, there is provided: (a wearable apparatus, comprising:) an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to block a ball from exiting the arm portion when the ball is thrown by the user from inside the arm portion. (In line with what has been previously mentioned, according to this aspect of what is invented, the 'arm portion’ may be the whole of the apparatus. Thus the term 'portion', (with respect to the term 'arm portion’), should not be seen as overly limiting, for example and should not be seen as meaning that there must be other 'portion(s)7’part(s)’). (According to this aspect of what is invented, the wearable apparatus may or may not comprise a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user)). According to another aspect of what is invented, there is provided: an invention as defined anywhere else in the present application, but where, rather than use of the term ‘ball’, the term ‘projectile’ is used. To explain, the present application includes significant disclosure relating to ‘throwing’. A ‘ball’ is referenced many times as the thing being thrown. However, it is here stated that, wherever the term ‘ball’ is used, an invention may be claimed not limited to use of the term ‘ball’, but instead using the term ‘projectile’. A ball is a ‘thing to be thrown’, (and thus is a projectile). However, it is feasible a projectile could be used that is not a ball. Thus it is here stated, (at least by virtue of this here statement), that a claim using the term ‘projectile’ (rather than ‘ball’), is supported, and may draw upon any disclosure in the present application, but may then use the term ‘projectile’, (in a claim(s), for example), rather than the term ‘ball’. Thus this is made clear and it has been made clear, (at least by virtue of this here statement), that this is supported. (Examples of a ball, (the term ‘ball’ of course not limited to these examples), would be, for example, a cricket ball, a baseball, a softball, a tennis ball, or even a football (with regard to British / European meaning of the sport ‘football’), or an (American) football, (with regard to American meaning of the sport ‘football’), for example, etc. However, it is thought a baseball, a softball, (or even a cricket ball) may be particularly relevant to what is disclosed in the present application). (It should be noted, if the ball is of a significant size, (eg a football, (eg with regard to British / European meaning of the sport ‘football’, for example), it is possible embodiments may be provided where the hand end of the arm portion is larger, (eg compared to other embodiments). It is even possible other portion(s) of the arm portion may be larger to cater for this a larger, (significantly sized), ball. (It is even possible a whole of the arm portion may be larger to cater for this, (eg compared to other embodiments)).

Note: At some patent offices, when daim(s) are allowed for patent, it is required that Figures that do not show all the feature(s) of the / an invention claimed (and / or that are not within a scope of what is claimed) are denoted as 'not being claimed’ or 'not within a scope of what is claimed’ (or words to that effect). Even in such case, it will be apparent that such Figure(s) may or do show feature(s) that are essential, or preferable and / or optional, to the / an invention claimed, which will be apparent, in light of the disclosure. Thus such Figure(s) (and / or disclosure related to such Figure(s) and / or embodiment(s)), should nevertheless be considered relevant to the / an invention claimed. Detailed Description Referring to the drawings, there is shown a wearable apparatus 10, comprising: an arm portion 12, for a throwing arm 13 of a user, the arm portion 12 being enclosed at a hand end 14 of the arm portion 12; and a securing portion 16 that travels around a reverse side R1 of the user, reverse with respect to side wearing the arm portion, to secure the arm portion 12 to the user. To make particularly clear what is intended by 'reverse side’ (of the user), (reverse with respect to side wearing the arm portion), Fig 1 is provided. Fig 1 shows a basic image of a person, (female, in the example). It is shown from a ‘perfect’ front view. Dashed line A1 ‘splits’ the person, right down the middle. It is clear that, (since the representation of the person is facing towards the view of Fig 1), the person’s right side (including their right arm) is shown on the left side of the image (and the left side of dashed line A1), and the person’s left side (including their left arm) is shown on the right side of the image, (and the right side of dashed line A1). Let us now imagine, for this example, that this person is right-handed, and that their throwing arm is therefore their right arm, in this example. (Whilst a right-handed person could throw left-handed, let us imagine, for the sake of this example, that the person depicted in Fig 1 is going to use the wearable apparatus 10 for throwing with their right arm, and that therefore their right arm, (shown on the left side in Fig 1 due to the view shown), is their throwing arm. Thus their right arm is numbered ‘13’ as being the 'throwing arm’ in this example. (Please see Fig 2 for a very good (and more realistic / true-to-life) depiction / example of a person whose throwing arm 13 is their right arm, wearing the example arm portion 12 of an example embodiment of the wearable apparatus 10 around their right arm). Therefore, again looking at Fig 1, if their right arm is their'throwing arm’, (as suggested / made clear by its numbering with feature number ‘13’ in Fig 1), then, from the view shown in Fig 1, everything on the right side of the dashed line A1 is the ‘reverse side’ of the user from the ‘throwing arm side’ of the user. This side is numbered 'RT in Fig 1, (clearly denoted). Thus meaning of ‘reverse side’ of the user (reverse with respect to side wearing the arm portion), is made clear. (It should also be stated therefore, (from this), that, in such an example as described, (with reference to the example shown in Fig 2, for example), all that is left of the dashed line A1 in Fig 1 would be the 'side wearing the arm portion’). Again with reference to what is shown in Fig 2, the side wearing the arm portion 12 may be referred to as a 'throwing arm side’, (if desired). (Thus, in such an example as described, (with reference to the example shown in Fig 2, for example), all that is left of the dashed line A1 in Fig 1 would be the 'throwing arm side’ of the user). In Fig 2, an example is shown, being worn. An example securing portion 16 of the example wearable apparatus 10 can be seen connected to an example arm portion 12 of the example wearable apparatus. The example is shown simply by way of example, but is thought to be helpful in understanding what is disclosed. In the example, it can be seen how the example securing portion 16 secures the example arm portion to the user. It can be seen how the example securing portion is useful in providing stability. (It should be stated, the term being ‘enclosed’ at a hand end 14 of the arm portion 12 has been used. It should be stated, such language would include within its scope embodiments where the hand end is 'permanently' enclosed, and would also include within its scope embodiments where the hand end could be opened, and then enclosed. An enclosable embodiment such as that is therefore clearly stated as being within a scope of the language used. (Thus an embodiment where the hand end could be opened, and then could be enclosed, (in order to then use the apparatus to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion 12), would be within the scope of the arm portion 'being enclosed’ at a hand end 14 of the arm portion 12, (and that is here made clear). Preferably the securing portion 16 travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to a torso of the user. This is clearly the case in the example of Fig 2, which shows, (generally around a general area denoted as area X1), the example securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso. (The embodiments disclosed in Figs 3-6 are also considered to be (and are) within the scope of 'wherein the securing portion 16 travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso’, because, when worn, this will clearly be the case. (The examples are within a scope of being configured for the securing portion to travel around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso). (The examples are within a scope of being shaped for the securing portion to travel around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso). (Further explanation / attention will be provided with regard to the embodiments shown in Figs 3-6)). The reason this, (ie travelling around the reverse side of the user, 'lower than where a reverse side arm of the user is attached to the torso’), is important is that it provides significant benefits in terms of securing and / or stability, (as opposed to the securing portion travelling around the reverse side of the user, but not lower than where a reverse side arm of the user is attached to the torso). To explain, Fig 1 (and the description of Fig 1), made clear that all that is to the right of line A1, (in the example, (and particularly with reference to Fig 2), is the 'reverse side’ of the user, (to side wearing the arm portion). And whilst the examples in Figs 2-6 show good examples of examples where the securing portion 16 travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, it should be stated, even a sling-type arrangement, where the securing portion merely travels around a reverse side of the user, but not under the arm of the user, would be within the scope of wherein the securing portion travels around the reverse side of the user. Thus, even in such an example, where the securing portion travels around the reverse side of the user, but only around the neck / shoulder area, for example, would still be within the scope of wherein the securing portion travels around the reverse side of the user. However, there are significant benefits of the securing portion travelling around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso. (These significant benefits will be explored). (The term 'lower than where a reverse side arm of the user is attached to the torso’ (of the user) simply means anywhere from the armpit or lower. For example, even something travelling around reverse side of the user, around the leg, (eg as low as the ankle, for example), would be with a scope of travelling around the reverse side of the user, under the arm of the user. Thus the term lower than where a reverse side arm of the user is attached to the torso’ is a broad term. However, as seen best in Fig 2, there are particular benefits of the securing portion travelling around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, at waist level or higher. (To make clear then, travelling around the neck / shoulder and / or head is not considered to be within the scope of 'under an arm’). (Note: An embodiment where the securing portion comprises a portion that travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, at waist level, and also comprises a portion that travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, at higher than waist level is, for the sake of the present application, considered to be within a scope of wherein securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, at waist level or higher. Therefore the term ‘at waist level or higher’ is used inclusively)). (Fig 2 is clearly within a scope of wherein the securing portion travels around a torso of the user, at the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and the securing portion also travels around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). Preferably the securing portion 16 also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso. This is clearly the case in the example of Fig 2, which shows, (generally around a general area denoted as area X2), the example securing portion travels around the side wearing the arm portion, under the arm of the user. Again, (as should be clear by viewing the example in Fig 2), this produces still further benefits, in terms of securing / stabilizing. (The examples are within a scope of being configured for the securing portion to also travel around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). (The examples are within a scope of being shaped for the securing portion to also travel around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). (The embodiments disclosed in Figs 3-6 are also considered to be (and are) within the scope of ‘wherein the securing portion also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso’, because, when worn, this will clearly be the case. (Further explanation / attention will be provided with regard to the embodiments shown in Figs 3-6)). Preferably a portion or a whole of the arm portion 12 is provided by way of a removably attachable arm portion attachment 18, removably attachable to the securing portion 16, the arm portion attachment comprising the hand end 14 of the arm portion. (Disclosure is provided in the present application within a scope of wherein at least a portion of the arm portion is removably attachable to the securing portion, the at least a portion of the arm portion comprising the hand end 14 of the arm portion). (The examples of Figs 2-6 are all examples within a scope of this, (although the / an example removably attachable arm portion attachment 18 is not shown in Figs 5 and 6, simply to provide more focus / clarity as to what is being shown with regard to the example securing portion). However, this is particularly well shown / denoted in Figs 3 and 4, and is also denoted well in Fig 2. Examples are shown within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion, and spanning at least half length of the arm portion. (Although, it should be stated, a removably attachable arm portion attachment could be provided that does not span at least half length of the arm portion). (Disclosure is provided in the present application within a scope of wherein at least a portion of the arm portion is removably attachable to the securing portion, the at least a portion of the arm portion comprising the hand end 14 of the arm portion, and spanning at least half length of the arm portion). (Figs 2, 3 and 5 clearly show good examples of this). (Note: Rather than the term 'spanning’, (simple) terms such as 'being’ may be used. Other terms may be used. For example, rather than the term 'spans’, the term 'travels along’ (or the like) may be used, for example. All these terms are deemed supported, and it will be apparent that there is a significant amount of disclosure in the present application). It should also be stated, whilst, in the example, the arm portion attachment surrounds the arm of the user, (when worn), at all points along its (ie the arm portion attachment’s) length, this need not be the case- embodiments can be provided where this is not the case. For example, an embodiment could be provided where an arm portion attachment, (and note, this disclosure is not limited only to embodiments that comprise a removably attachable arm portion attachment- this disclosure is relevant also generally to an 'arm portion’, (whether there be a removably attachable arm portion attachment or not), is provided that comprises the hand end of the arm, and it could go around the hand of the user, but, for example, could then go around the wrist eg 'non-loosely' enough to stop the ball escaping when thrown and non-loosely enough, for example, to at least provide some benefit of playing a role in the hand of the user not easily falling back out. (Thus disclosure has been provided of this. And disclosure is here provided, (with reference to this), of the securing portion preventing the hand from falling back out, when the ball is thrown). (It has been disclosed how a benefit of the / a securing portion is that it can lessen or eliminate the need for any ‘tightness’ / ’compression’ being applied to the throwing arm itself). For example, it could elastically fit around the wrist (or any (relevant) part(s) of the arm)), in such a way that the hand (and ball) can go into it, with it being 'non-loose’ enough, (around the wrist, for example), to stop the ball escaping when thrown and ‘non-loose’ enough, for example, to at least provide some benefit of playing a role in the hand of the user not easily falling back out, (unless it is elastically deformed (by the user) to get the hand out, for example). (Elasticity is only one way to achieve this- other ways may include some sort of arrangement to make it ‘non-loose’ enough, to stop the ball escaping when thrown and ‘non-loose’ enough, for example, to at least provide some benefit of playing a role in the hand of the user not easily falling back out. One example might be hook-and-loop type element(s), (eg strap(s)), which can be used to make it 'un-loose’ enough around the wrist, for example, (or any (relevant) part(s) of the arm)). A similar method could be used but with buttoning, (to enclose the hand, for example), rather than hook-and-loop type element(s), for example- any way(s) / method(s) / feature(s) may be used, (to enclose the hand, for example). Thus various options and / or embodiments are possible, the examples provided simply by way of example only). In a possible embodiment, rest of the arm portion could then attach to such an example removably attachable arm portion attachment, (generally at the wrist, for example, (or at any relevant place(s), depending on length of the arm portion attachment). It should also be stated, in another possible embodiment, from the wrist area, (or any relevant area), the arm portion attachment could then comprise an elongate element(s), eg a strap(s), for example. This could travel much or all the way up the rest of the arm, for example, (eg to the shoulder area, for example), thus facilitating the arm portion attachment being attached to the securing portion. Eg, looking at Fig 2, for example, if one imagines such an embodiment, and that, rather than the arm portion attachment surrounding the arm, there is, for example, an elongate element, (eg a strap, for example), that runs generally from around the wrist area up generally to where the example arm portion attachment attaches to rest of the arm portion / to the shoulder area, for example), then this will also be within the scope of wherein the arm portion attachment spans at least half length of the arm portion. (In such an embodiment, it might benefit the embodiment if there is another elongate element, (eg travelling up the other side of the arm / arm portion), which may provide greater stability of the hand end, (especially in use), for example. (Thus there may be a plurality of elongate elements). (It should also be stated, embodiments could be provided where the elongate element(s), (and / or relevant feature(s)), do not attach to another part(s) of the arm portion, but instead attach directly to the securing portion- for example, looking at Fig 2, if it is imagined that feature 26 is not present, the the elongate element(s), (and / or relevant feature(s)), could attach / connect directly to the securing portion much higher up, to the torso area around the shoulder, rather than at a higher point up the arm. Thus various options and / or embodiments are possible). (It should be stated, an embodiment eg such as one mentioned / alluded to, where a portion of the arm portion encloses the hand, for example, (eg being 'non-loose’ enough to stop the ball escaping when thrown and ‘non-loose’ enough, for example, to at least provide some benefit of playing a role in the hand of the user not easily falling back out), and, for example, where there are then elongate elements that either connect to / attach to portion 26, or even directly to the securing portion, for example, (with there not being a portion 26 to connect / attach to, for example), would be within the scope of the arm portion being an arm portion for being worn around at least a portion of the arm. (Thus such disclosure would be within the scope of the arm portion being an arm portion for being worn around a portion or a whole of the arm). (Thus disclosure is provided within a scope of the arm portion being an arm portion for being worn around at least a portion of the throwing arm). (Thus disclosure is provided within a scope of the arm portion being worn around the hand of the throwing arm). (Thus disclosure has been provided within a scope of the arm portion being an arm portion for being worn around the throwing arm, at least up to the wrist of the throwing arm, (in the example mentioned)). (Thus disclosure has been provided within a scope of the arm portion surrounding the arm for at least one quarter length of the arm portion). (Thus disclosure has been provided within a scope of the arm portion surrounding the arm for at least one third length of the arm portion). (Thus disclosure has been provided within a scope of the arm portion surrounding the arm for at least half length of the arm portion). (Thus disclosure has been provided within a scope of the arm portion surrounding the arm for at least two thirds length of the arm portion). (Thus disclosure has been provided within a scope of the arm portion surrounding the arm for at least three quarters length of the arm portion). (And it may be that the arm portion surrounds the whole arm of the user). (It should be stated, these length definitions support whether the length definition is achieved ‘continuously’, or by multiple portions, in total. (Thus the broad term 'in total’ may be used, for any such definition, (which includes both possibilities within its scope)). To explain, if definition is provided that 'the arm portion surrounds the arm for at least half length of the arm portion’, then that includes within its scope whether the arm portion at any point 'continuously’ surrounds the arm for at least half length of the arm portion’, and also includes within its scope if the arm portion does not, at any point, ‘continuously’ surround the arm for at least half length of the arm portion, but, in a ‘non-continuous’ manner, does, in total, surround the arm for at least half length of the arm portion). (Eg if the arm portion surrounds the arm for a quarter length of the arm portion, and then has a portion (eg higher up the arm) that does not surround the arm, and then, (eg still further up the arm), again then surrounds the arm for a quarter length of the arm portion, then it is within a scope of surrounding the arm for 'at least half length of the arm portion, (because one quarter plus one quarter is 'half, which is within scope of 'at least half). (The term 'in total’ may be used, simply for extra clarity). (All such length definition may be afforded to the / an arm portion attachment, (for embodiments that comprise a removably attachable arm portion attachment), if so desired. Thus support for this is here made clear. (And it has been made clear that disclosure has been provided of embodiments wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, which is thus again made clear). Thus whilst Fig 2 shows a particularly preferred embodiment, it should be stated, various options and / or embodiments are possible, with reference to the / an arm portion. Thus this has been made clear). (Note: It should be stated, even for an embodiment where the arm portion only surrounds the hand / wrist, (eg being ’non-loose’ enough to stop the ball escaping when thrown and 'non-loose’ enough, for example, to at least provide some benefit of playing a role in the hand of the user not easily falling back out), and then comprises an elongate element(s) that may even then connect directly to the securing portion at a torso area of the user, (or to a portion 26, for example, in relevant embodiments), throwing the ball would still be within the scope of the ball, (when the ball is thrown by the user), being thrown from ‘inside’ the arm portion. Thus even in such embodiments, when the ball is thrown, it is considered to have been thrown from ‘inside’ the arm portion. Thus this is made clear). (And it should be said, structure / feature(s), for example, that enclose the hand (eg around the wrist), also having the effect of preventing the ball from escaping when thrown give benefits that have been disclosed in the present application with reference to preventing the ball from escaping). (And it should be stated, (as has been made clear), that embodiments of the structure disclosed could be provided in embodiments where there is a removably attachable arm portion attachment, but are not limited to this- ie any such structure is possible for embodiments where there is not a removably attachable arm portion attachment. Furthermore, with ‘reference to elongate element®’, it is possible such elongate elements may be removably attachable to one or both part(s) they connect, or may not at all be removably attachable. Thus various options and / or embodiments are possible)). (It should also be stated, the embodiments just described, (ie referring generally to disclosure generally with reference to where the arm portion comprises an elongate element(s) (where the arm of the user is not ‘surrounded’), could be provided even in an embodiment where there is not a removably attachable arm portion attachment- ie where the arm portion is shaped / designed / structured in that way, with there not being a removably attachable arm portion attachment. Thus various options and / or embodiments are possible, and this has been clearly stated, clearly showing that various and many embodiments are not limited to ‘surrounding’ the arm in the way, for example, that a particularly preferred embodiment shown in Fig 2 does, shown simply by way of example only). (That having been said, it should be stated, the embodiment shown in Fig 2 is within a scope of wherein, distance between end of the arm portion (at the hand end) to furthest away (‘highest’ up arm / arm portion) that the arm portion surrounds the arm is at least half length of the arm portion. (So, in the example, the example removably attachable arm portion attachment is within a scope of wherein distance between end of the arm portion (at the hand end) to furthest away ('highest' up arm / arm portion) that the arm portion attachment surrounds the arm is at least half length of the arm portion. (And, having here used the definition 'at least half (length of the arm portion), it is here made clear that disclosure is provided of (and it is thus supported and may be claimed, (both generally for the 'arm portion’ and for a 'removably attachable arm portion attachment’)), the definition of 'at least a quarter’ (length of the arm portion); 'at least a third’ (length of the arm portion); ‘at least two thirds’ (length of the arm portion); 'at least three quarters’ (length of the arm portion). Thus all these are supported, (with reference to distance between end of the arm portion (at the hand end) to furthest away ("highest’ up arm / arm portion) that the arm portion attachment surrounds the arm). It should also be stated, this is not limited to the arm portion / arm portion attachment having to surround the arm at all points between end of the arm portion (at the hand end) to furthest away ('highest’ up arm / arm portion) that the arm portion attachment surrounds the arm. Thus there could be ’gap(s)7’area(s)’ between end of the arm portion (at the hand end) to the point furthest away ('highest’ up arm / arm portion) that the arm portion attachment surrounds the arm. Thus this has been made clear and has been stated dearly))). (It should be stated, examples are shown within a scope of wherein the / a removably attachable arm portion attachment spans at least a quarter length of the arm portion). (It should be stated, examples are shown within a scope of wherein the / a removably attachable arm portion attachment spans at least a third length of the arm portion). (It should be stated, examples are shown within a scope of wherein the / a removably attachable arm portion attachment spans at least two thirds length of the arm portion). (It should be stated, the / a removably attachable arm portion attachment may span at least three quarters length of the arm portion). (Examples are shown within a scope of wherein the removably attachable arm portion attachment, from a top-most point that it goes around the arm to a bottom-most point that it goes around the arm, spans at least a quarter length of the arm portion. (So the same, (rather than the definition 'at least a quarter’), for the definition 'at least a third’; 'at least a half’; 'at least two thirds’; (and it is also stated that, from a top-most point that it goes around the arm to a bottom-most point that it goes around the arm, the / a removably attachable arm portion attachment may span at least three quarters length of the arm portion). Thus all such terminology / definition is disclosed and supported). (The term ‘bottom-most’ here would be referring / relating to the hand end of the removably attachable arm portion attachment, and the term ‘top-most’ would thus here be referring to 'higher up’ the arm, (ie further away from the hand end)). (Rather than using the terms 'top-most’ and 'bottom-most', language may be used to refer to distance between the hand end of the arm portion / arm portion attachment and the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user. (Rather than the term 'furthest point [from]’, the term 'most distant point [from]’ may be used). (Examples are shown within a scope of wherein distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user is at least a quarter length of the arm portion). (Examples are shown within a scope of wherein distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user is at least a third length of the arm portion). (Examples are shown within a scope of wherein distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user is at least half length of the arm portion. (Examples are shown within a scope of wherein distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user is at least two thirds length of the arm portion). (And it should be stated, the distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user may be at least three quarters length of the arm portion). (See distance D1 in the example of Fig 4 to see an example of this distance / length, in the example embodiment of Fig 4, with dashed arrowed line D1 generally denoting this distance / length in the example, (ie distance from the hand end to the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user). (Dashed arrowed line D1 in Fig 4 is seen generally denoting distance between where the removably attachable arm portion attachment is enclosed at the hand end and the furthest point from the hand end at which the removably attachable arm portion attachment travels around the arm of the user. (It can very clearly be seen, in the example of Fig 4, that the distance D1 is within a scope of being at least a quarter length of the arm portion). (A significant amount of disclosure, (both pictorial (ie in drawing(s)) and textual disclosure), has been provided in the present application with regard to the / an arm portion being worn about the throwing arm of the user). (Note, a significant amount of disclosure has been provided in the present paragraph, and some of the disclosure mentions a removably attachable 'arm portion attachment’. It should be stated, it is made clear in the present application that embodiments can be provided where there is not a removably attachable arm portion attachment, and it is therefore here clearly stated that such feature(s) / disclosure, (even where disclosed / mentioned relating to a removably attachable 'arm portion attachment’), where possible, is not limited only to embodiments that comprise a removably attachable arm portion attachment-thus such disclosure can be relevant also generally to an 'arm portion’, and may be afforded generally to an 'arm portion’, (whether there be a removably attachable arm portion attachment or not), and this is here made clear. (This is also broadly made clear, with reference to disclosure in the present application, not limited to the present paragraph). (It is here stated that any feature(s) / disdosure provided / disdosed, (with regard to an ‘arm portion’), in the present application relating to an embodiment that comprises a removably attachable arm portion attachment may be afforded to an embodiment(s) that does not comprise a removably attachable arm portion attachment, where such feature(s) / disdosure can be provided for an embodiment that does not comprise a removably attachable arm portion attachment. Thus this has been made clear and is clearly stated)). (It should be stated, embodiments may be provided where the whole arm portion is removably attachable, (to the securing portion). Thus an arm portion attachment can be provided that comprises a whole of the arm portion. Thus this has been disclosed). Note: It should be noted, various parts are disclosed in the present application, shown / provided as one part, (whether or not that one part is manufactured from multiple parts that are permanently attached together, (eg sewn / stitched for example)). It should be stated, generally speaking, anything provided in / as one part can, if so desired, be provided in multiple parts, (for the user to attach together). However, this potentially provides more complexity, (eg in manufacture and / or assembling / disassembling things together and / or creating more fail points). However, it should be stated, it has now been made clear this could be the case. Examples are shown in the Figures of an arm portion 12, provided simply by way of example only. Looking, by way of example only, particularly at Fig 3, (since Fig 3 shows various portions of the / an example arm portion 12 so clearly), in the example, (provided simply by way of example only), the example arm portion comprises an example top portion 26. In the example, (provided simply by way of example only), the example arm portion comprises an example portion 38. In the example, example portion 38 comprises netting. (This is clearly visible both in Figs 3,4, and also in Fig 2). (Note: It should be stated, the term ‘netting’ is used in the present application. Some people may use the term ‘mesh’, for example. It should be stated, for the sake of the present application, the term ‘netting’ will be used as a broad term, and is considered to include within its scope the term ‘mesh’. (Note: The term 'netting' is used to imply where there are holes, (and thus that there are 'apertures’). It will be apparent that materials that do not have holes can have 'mesh’ type material / structure embedded within them or onto a surface(s) of theirs. (Such material(s) could be used, (eg for example portion 38), but may not provide benefit(s) that netting provides, (especially, as will be mentioned, in terms of aeration, for example)). However, the term 'netting’ is used in the present application meaning / implying netting structure where there are apertures, (which is clearly denoted in the Figures where netting is depicted)). Netting is here particularly useful. One of the reasons it is useful is because it allows at least a portion of the user’s throwing arm to be viewable / visible. (ie As opposed to not being visible, eg in an embodiment where not any of the throwing arm is visible through the arm portion, for example). This can have significant benefits. For example, the user’s throwing technique can be analysed. Thus, if a professional, (either carrying out general sports training, and / or rehabilitation from (arm) injury, for example), is able to view the throw, (either live, or, even better still, retrospectively via video footage), being able to see at least a portion of the user’s arm could be extremely important, in analysing technique. (Whilst it is technically feasible that the whole of the user’s throwing arm may be visible, preferably a portion (but not the whole) of the user’s throwing arm is visible, (and this is particularly well shown by / in Fig 2). It is thought that ability to see the user’s elbow is particularly important, with reference to analysing throwing technique, (since position / bending of the elbow can be a big factor in good / bad technique). Thus preferably at least the elbow joint of the user’s arm can be seen, through the arm portion. However, (as shown in the examples of Fig 2 and Figs 3, 4), preferably at least (or more than) half length of the user’s arm can be seen through the arm portion. In the example embodiments, (provided simply by way of example), at least (or more than) half length of the arm portion can be seen through. (This is particularly well demonstrated by what is shown in Fig 2). (It should be stated, viewing of any part(s) / side(s) of the / an elbow is considered to be within scope of being able to view the / an elbow. In the example of Fig 2, for example, (and Figs 3,4), the elbow of the user is viewable (can be seen) from all sides. (This is particularly well demonstrated by what is shown in Fig 2), However, even if just one side, (eg the 'inner side’ of the elbow (the side where the elbow bends Inwards’), and / or the 'outer side’ of the elbow), is visible, that is considered to be within scope of the elbow of the user being visible. (Even if the elbow is visible at any point, (eg from one or both of what could be called the 'lateral' side(s) of the elbow, that is still considered to be within scope of the elbow of the user being visible. Thus is any portion(s) of the elbow is visible, that is considered to be within scope of the elbow of the user being visible / viewable). Thus it will be noted that, in the example embodiments, at least a portion of the arm portion can be seen through. (Thus, preferably, at least a portion of the arm portion can be seen through). For example, in the example of Fig 2, which shows a very good example of this, whilst being worn, it can be seen that generally example portion 38 of the example arm portion 12 is made of netting. (Thus it can be seen that example portion 38 comprises netting (and is within a scope of being a portion that ‘comprises netting’)). It can be seen that the user’s throwing arm 13 can be seen through this. This can be useful for analysis of technique. For example, a trainer could monitor arm position(s) of the user, when throwing. As mentioned, of particular attention may be position (eg bending) of the elbow. Thus preferably the / an elbow area / portion of the arm portion can be seen through. (It should be stated, netting is just one example of how a portion(s) can be seen-through. Another example would be the use of transparent material(s), for example. (Thus another possibility would be a portion(s) being transparent. (Note: the terminology 'at least partially transparent’ may be used. (A material(s) could be used that is not fully transparent, but is transparent enough to be able to see relevant (portion(s) or whole) of the arm through it. Thus the term ‘at least partially transparent; may be used, and it should be stated, wherever there is disclosure in the present application of the term ‘transparent’, it is here clearly stated that the terminology / definition 'at least partially transparent is supported. Thus this has been made clear)). For example, transparent plastic(s) of the like could be used. However, netting is heavily preferred, because it also allows for aerating. If transparent plastics were used, aeration may be a problem, which could lead to increased sweating for example. This could even lead to increased risk of hygiene problems. Furthermore, netting is more likely to be light in terms of weight, which may well also be desirable. (Use of transparent plastics may be heavier). Furthermore, transparent plastics may not flex well, and therefore may create some problems / resistance for the thrower during the throwing action. Netting, on the other hand, tends to be extremely good at not creating resistance, and simply changing shape. It should also be stated, broadly speaking, netting is an example of wherein there are a plurality of apertures. Embodiments could be provided where there is an aperture(s) that allows for visibility of at least a portion of the arm of the user, but without netting. For example, there could be larger aperture(s). However, as stated, (for the reasons given above and / or any other reason(s)), it is thought netting is significantly advantageous. One of the other benefits of netting is that netting can easily be provided with many apertures that are far too small for there to be any possibility that the ball can escape through them. (Thus there being aperture(s) has been disclosed. Thus transparency has been disclosed. Thus various options and / or embodiments are possible, (with regard to being able to see a portion(s) of the throwing arm of the user). (Thus disclosure has been provided of being able to see at least a portion of the throwing arm of the user)). (Note: The holes / apertures, (of the netting, in the example), in Fig 2 may, for example, in a preferred embodiment, be approximately half the size of how they are represented in Fig 2. (Double as many lines, generally upward, could have been used, for example, to denote as such). The example holes / apertures in Fig 2 are shown / represented as larger simply for clarity / simplicity sake, (especially to make sure items such as the throwing arm can be seen with extremely good clarity). Nevertheless, it is stated, the holes / apertures may be smaller than what is denoted, in a preferred embodiment. (Similarly, the holes / apertures, (of the netting, in the example), in Figs 3, 4 and 7 (and Figs 10-13) may, for example, in a preferred embodiment, be approximately a quarter the size of how they are represented in Figs 3,4 and 7 (and Figs 10-13). The example holes / apertures are shown / represented as larger simply for clarity / simplicity sake. Thus it is stated, the holes / apertures preferably are smaller, for example, than what is shown in Figs 3, 4 and 7 (and Figs 10-13))). In the example, (provided simply by way of example only), the example arm portion comprises an example portion 40. In the example, the (provided simply by way of example only), the example arm portion comprises an example portion 19. It should be stated, these portions could be provided as one part. However, in the example embodiments, (provided by way of example only), they are provided as two parts. (They are attached together, as will be explained). To explain, portion 19 is provided as a separate part, for reasons of helping with auditory feedback, when the ball is thrown. To explain, at the hand end of the arm portion, there is a contact portion, where the ball contacts when it is thrown. As is disclosed in the present application, the nature of the sound created can give feedback with respect to the throw. For example, generally the louder the sound, generally the more powerful the throw. But the nature of the sound can also give feedback as to the quality of the throw. To explain why the embodiments are provided with portion 19 being a separate part to portion 40, (which are then attached together in the examples), if portions 40 and 19 are provided as one part, eg a band of material that is then 'crimped’ and attached together (eg sewn) right at the end of the arm portion, that can lead to little or no sound being produced when the ball, internally, hits the hand end of the arm portion. Thus when the ball contacts the contact portion, such a version can lead to little or not sound being produced. Even if sound is produced, it may be dulled and / or mottled, for example. However, in the examples shown, (and at least in part due to that reason), portion 19 is provided as a separate part. In the examples, it is shown attached at basically denoted example line / stitching 42, but may be attached in any way, (the example provided simply by way of example only). (Eg it could be stapled, heat-bonded, connector(s) may or may not be used, (and any combination of these is possible), etc, etc, with these just being some examples of how it could be attached). This allows for portion 19 to be provided being of a shape / nature that produces a better sound, when the ball hits the contact portion / area. For example, in the examples shown, (shown by way of example only), this allows for a louder sound. For example, in the examples shown, (shown by way of example only), this allows for a clearer sound. This can allow for better auditory feedback, because when a loud(er) sound is achieved, it can help the user known they have performed a good throw. This can allow for better auditory feedback, because when a dear(er) sound is achieved, it can help the user known they have performed a good throw. (Even if the user has not thrown the ball ‘harder’, they may thus be able to achieve, (relatively to a throw where they threw the ball just as ‘hard’), a louder sound, due to performing a better quality throw. Thus feedback can be received as to quality of the throw. Thus feedback could be received with regard to 'timing' for example. (Those who play sports such as tennis, golf, baseball, softball, cricket, (and generally 'ball-striking’ sports), or even actions such as throwing, will know how important ‘timing’ can be. Good timing tends to lead to a better result. (In throwing, good timing could lead to more accurate throwing. In throwing, good timing could lead to more powerful throwing). Thus auditory feedback can be provided / received. In the examples shown, portion 19 being provided separately gives more options in terms of what shape the hand end of the arm portion is, (and also how the hand end will react / distort, when the ball, internally, is thrown against it). In the examples shown, it allows for a ‘flatter’ end portion / contact portion / area. This creates a shape that could be described as more of a ‘wall’ for the ball to engage with / against, when thrown. Again, this can be beneficial in terms of the sound generated. For example, it may allow a louder sound to be generated when the ball is thrown. For example, it may allow a clearer sound to be generated when the ball is thrown. Thus this can help with auditory feedback. (It should also be stated, providing portion 19 as a separate part can help avoid any seam / sewing being in the area that the ball engages, when thrown. Again, this can be beneficial in terms of auditory feedback. For example, it may allow a louder sound to be generated when the ball is thrown. For example, it may allow a clearer sound to be generated when the ball is thrown). (A portion or a whole of the hand end, (where the ball engages when thrown), may be made of stiffer material than a portion or a whole of rest of the arm portion. Stiffer material may be useful in producing the sound effect desired, (when the ball is thrown). A portion or a whole of the hand end, (where the ball engages when thrown), may be thinner than a portion or a whole of rest of the arm portion. (Appropriately thin and stiff material may be particularly useful). Broader speaking, a portion or a whole of the hand end, (where the ball engages when thrown), may be constituted differently than a portion or a whole of rest of the arm portion. (A portion or a whole of the hand end, (where the ball engages when thrown), may be constituted differently most or all of rest of the arm portion)). (It should be noted, in the example embodiment of Fig 2, there is shown an example portion 36. In the example, the example connector 20a (shown in Fig 2), attaches to this portion / area. (This is shown simply by way of example). In the example, this portion travels around the whole of the arm of the user. However, in other embodiments, it may travel around a portion (but not a whole) of the arm of the user. It is feasible it may travel around at least (or more than) half the way around the arm of the user. It is feasible it may travel around at least (or more than) two thirds the way around the arm of the user. It is feasible it may travel around at least (or more than) three quarters the way around the arm of the user. In the example, example portion 36 is stretchy. (The term ‘elastic’ may be used). This can be helpful to cater for people with larger (thicker) arms, (ie where ‘girth’ of the arm is greater, with example portion 36 being able to stretch, to accommodate the arm). In the example, given shape of the example portion 36, (provided by way of example only), portion 36 may be referred to as a ‘band’. (As stated, the example is provided simply by way of example only, and in other examples, this may or may not be the case). This is simply one example of a portion of the arm portion (whether or not a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment), being stretchy / elastic. Broadly speaking, this is within a scope of wherein a portion or a whole of the arm portion is stretchable to a greater girth. (As stated, the term ‘elastic’ may be used). (And, as has been stated, this can be useful, to accommodate bigger / larger arms, (in terms of ‘girth’ of arm). Example portion 36, (and the example embodiment provided), is simply one example of this, not limiting such disclosure / concept. Thus this has been made clear). In the example of Fig 2, it will be seen how there is a portion 44. It is shown generally at area X7. In the example embodiment, this can be said to be ’beyond’ example portion 36. In the example embodiment, example portion 44 is 'higher up’ than example portion 36, (with reference to position, regarding the example arm portion). It has been found that this can decrease the chance of damage to the removably attachable arm portion attachment 18 (eg by ‘ripping’). To explain, in the example embodiment, portion 44 comprises netting. In the example embodiment, portion 44 is actually part of portion 38. It has been found that example portion 38 continuing ‘past’ example portion 36 ('higher up’ the arm / arm portion), lessens the chance of ripping (ie either portion 38 itself ripping, or portion 38 and portion 36 partially or wholly ripping apart from each other). It has been found that, by portion 44 extending 'past’ portion 36, this can eliminate or at least significantly reduce chance of ripping. Thus this may be important / beneficial. (Note: In the example, (provided simply by way of example only), portion 38 comprises netting. Thus, (in line with what portion 38 is made out of), portion 44 comprises netting. However, in other embodiments, portions 38 and 40 may not be made out of netting. Thus netting is simply shown by way of example only. It has been made clear that different materials may be used. Thus, for example, if portion 38 was provided as a fabric, for example, that is not provided as netting, then portion 44 may not comprise netting. Portion 38 and portion 44, (portion 44 being part of portion 38), could be made of any material(s), for example, not limited to netting, which is provided simply by way of example. It is even feasible the portion of portion 38 that is visible in Fig 2, for example, and portion 44 may be made out of different material(s). (They could be attached together, for example). Thus various options and / or embodiments, (including any possible combination(s) / permutation(s)), are possible, and this has been made clear. (In the example, example portion 36 is attached to example portion 38. (ie Portions 36 and 38 are attached to each other). This may be done by sewing, or any other relevant / appropriate method. (Various ways / methods of attachment have been disclosed in the present application). (Note: It should be stated, in the present application, the term 'sewing / sewn’, (etc), is used as a broad term, and includes within its scope ‘stitching’. It is here stated, (especially because ‘stitching’ has been mentioned / disclosed), that wherever the term ‘sewing / sewn’ (etc) is used, it is here stated that ‘stitching’ may take place, and is deemed supported (eg if included in a claim(s)). Thus for the rest of the present application, the broad term ‘sewn’ may or will be used. But, as stated, (particularly in light of this statement), we make clear that ‘stitching’ is supported, (eg if such term is used in a claim(s), for example). Thus this is made clear). (It should be stated, (looking at Fig 2, for example), if the portion that comprises portion 19 and portion 40, for example, was removably attachable, and rest of the arm portion 12 was not removably attachable, then that would be within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion. (Even if only portion 19 was removably attachable, and rest of the arm portion 12 was not removably attachable, then that would be within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion). However, it would not be within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion, and spanning at least half length of the arm portion). (What is shown, (in the examples of Figs 2, 3 and 4), is within a scope of wherein the removably attachable arm portion attachment 18 spans more than half of the arm portion 12). (What is shown, (in the examples of Figs 2,3 and 4), is within a scope of wherein the removably attachable arm portion attachment 18 spans at least two thirds of the arm portion 12). (What is shown, (in the examples of Figs 2, 3 and 4), is within a scope of wherein the removably attachable arm portion attachment 18 spans more than two thirds of the arm portion 12). (What is shown, (in the examples of Figs 2, 3 and 4), is within a scope of wherein the removably attachable arm portion attachment 18 spans at least three quarters of the arm portion 12). (What is shown, (in the examples of Figs 2, 3 and 4), is within a scope of wherein the removably attachable arm portion attachment 18 spans more than three quarters of the arm portion 12). Preferably the wearable apparatus comprises a connector 20a, to removably attach the removably attachable arm portion attachment 18 to the securing portion 16, the connector 20a being separately removably attachable to the removably attachable arm portion attachment and to the securing portion. (Figs 2,3 and 4 show good examples of this. The example of Figs 5 and 6 is also an example that functions in this way, but, as stated, the removably attachable arm portion attachment 18 is not shown in Figs 5 and 6, to provide more clarity and focus regarding the example securing portion shown. Similarly, in Figs 5 and 6, the / a connector 20a is not shown, (again, to provide more clarity and focus regarding the example securing portion shown)). In Fig 2, the / an example connector 20a is shown in action, (facilitating removable attachment of the example removably attachable arm portion attachment 18 to the example securing portion 16). In Figs 3 and 4, the / an example connector 20a is shown separately, (not in action). However, it will be clear from what is shown in Figs 3 and 4 how the example connector 20a could be used much in the same way as shown in Fig 2, in action / in use. (It should be stated, there could be more than one connector 20a, to removably attach the arm portion attachment to the securing portion, the connector being separately removably attachable to the removably attachable arm portion attachment and to the securing portion). However, the use of just one is preferred, because it is thought this makes attachment more simple / as simple as possible). Preferably the wearable apparatus utilizes hook-and-loop type attachment to removably attach the connector 20a to the removably attachable arm portion attachment and to removably attach the connector 20a to the securing portion 16. (This is the case in the examples shown). Before explaining, the term 'hook-and-loop type attachment’ is used here to include within its scope any hook-and-loop, hook-and-hook, loop-and-loop type attachment, and anything that would fall within a scope of what is often called, in laymen’s terms, 'Velcro®'. As will be known, Velcro® is a registered trademark, and therefore should not be used as a broad patenting term. This provides a problem, because, (despite any protestations of those that own the trademark), people generally refer to these types of attachment / securing solutions / features as 'Velcro®’. I have decided not to use the term 'hook-and-loop' as the broad term, because it is sometimes considered that ‘hook-and-hook’ or ‘loop-and-loop’ can be used to much the same effect. Therefore I have used the term ‘hook-and-loop type attachment’, and I here state that this should be interpreted as broadly as the every day laymen’s use of the term ‘Velcro®’. Thus the term ‘hook-and-loop type attachment’, (and the term 'hook-and-loop type’) is a broad term. (The term 'hook-and-loop type securing’ may be used. (The term 'hook-and-loop type securing element(s)’ may be used)). To explain, (regarding the wearable apparatus utilizing hook-and-loop type attachment to removably attach the connector 20a to the removably attachable arm portion attachment and to removably attach the connector 20a to the securing portion, example connector 20a is shown. (See Fig 2 and Figs 3,4). Looking at Fig 2, the example connector is attaching / connecting the example removably attachable arm portion attachment 18 and the example securing portion 16 together. (It is facilitating removable attachment of the example removably attachable arm portion attachment 18). In the example, the example connector 20a is doing this via being attached to the example removably attachable arm portion attachment 18 via hook-and-loop type attachment. (In other embodiments, an attachment method(s) other than hook-and-loop type attachment may be used, but it is thought hook-and-loop type attachment is particularly un-cumbersome and elegant, in use). (Note: It is feasible embodiments could be provided where hook-and-loop type attachment is used, and there is also provided another type of attachment method(s), (which can either be used instead of hook-and-loop type attachment, or perhaps even also with when hook-and-loop type attachment is used, (eg to create even further assurance, with regard to attachment)). Such embodiments are still considered within a scope of wherein hook-and-loop type attachment is ‘provided’ / ’utilized’. Such embodiments are still considered within a scope of wherein attachment is occurring 'via hook-and-loop type attachment’). It is also removably attached to the example securing portion 16, (albeit 'indirectly’, in the example). (The nature and meaning of 'indirect’ as opposed to 'direct’ attachment / connection will be explored / explained in the present application). In the example, (more precisely, it is attached to example portion 26 of the example arm portion. Because portion 26 is connected to the securing portion, the example connector 20a, in being attached to the example removably attachable arm portion attachment 18 and example portion 26, (and attaching example removably attachable arm portion attachment 18 and example portion 26 together), is attaching the example removably attachable arm portion attachment 18 to the example securing portion 16. In the example, the example connector 20a is directly attached to the example removably attachable arm portion attachment 18. In the example, the example connector 20a is directly attached to the example removably attachable arm portion attachment 18 via hook-and-loop type attachment. In the example, the example connector 20a is directly attached to example portion 26. In the example, the example connector 20a is directly attached to example portion 26 via hook-and-loop type attachment. (Hook-and-loop type attachment is just one possibility for attachment. Any attachment method(s) may be used. (For example, strap(s), could be used. For example, clip(s) could be used). However, it is thought hook-and-loop type attachment is particularly beneficial, especially in terms of quickness and ease of use). (It should be stated, whilst example connector 20a is shown being 'indirectly' attached to example securing portion 16 in the example of Fig 2, in other examples, it is possible connector 20a could be directly attached to securing portion 16. For example, if the whole arm portion is provided by way of being removably attachable, (which would be an example of wherein the / a removably attachable arm portion attachment comprises the whole of the arm portion), then a connector 20a could be used much in the same way as shown in Fig 2, but attaching directly to the arm portion, (and thus the removably attachable arm portion attachment, in such an embodiment), and attaching directly to the securing portion. (Such an example, (provided simply by way of example only) would be within a scope of wherein the wearable apparatus comprises a 'separate' connector, to facilitate connecting the arm portion and the securing portion). Thus various options and / or embodiments are possible. (In the example shown in Fig 2, it can be seen that example portion 36 is usable for hook-and-loop type attachment. It should be stated, various options and / or embodiments are possible, in terms of design of an arm portion / removably attachable arm portion attachment, and the example shown is provided simply by way of example only. In other embodiments, (eg that generally use similar such function / attachment), the / a portion that a connector 20a is attached to may be very differently shaped / designed / sized, etc. Thus various options and / or embodiments are possible and the embodiment(s) shown are provided simply by way of example only). (Note: Much the same as stated above with regard to connectors) 20a, (with regard to any disclosure relating to attachment / connection), may be the case / afforded to connector(s) 20b, (and vice versa). Thus any option(s) disclosed with regard to connector(s) 20a, (with regard to nature of attachment / connection) may be afforded to connector(s) 20b. Thus this has been made clear. (Further disclosure will be provided with reference to connector(s) 20b)). Preferably attachment position of the arm portion attachment is adjustable, to adjust length of the arm portion. (This is clearly the case in the examples of Figs 2,3 and 4, for example). To explain, looking at Fig 3, for example, the example removably attachable arm portion attachment 18 could be attached, (using the example connector 20a, in the example), in the position it is shown in Fig 3. However, if a user wanted the arm portion to be shorter in length, they could attach the removably attachable arm portion attachment 18 higher up. (They could position it higher, and then use the example connector 20a to attach it in that position. Thus an example is shown of wherein the attachment position of the arm portion attachment is adjustable, to adjust length of the arm portion. Preferably the wearable apparatus comprises a visual aid 21, to denote attachment position of the arm portion attachment to the user. (This is best seen in Figs 3 and 4. Fig 2 also comprises a visual aid 21, (numbered in Fig 2), but much of it is not visible due to the view / angle shown, (and also that example connector 20a is over much of it). In the example so clearly shown in Figs 3 and 4, the visual aim comprises a plurality of visual aid elements. In the example, the visual aid element are lines. (However, this is provided simply by way of example only, and in other embodiments, a visual aid element(s) may be any shape, for example). In other embodiments, there may only be one visual aid element, rather than a plurality. For example, an embodiment could be provided where there is only one 'line’ (as opposed to multiple lines, as in the example visual aid shown). This would still be within the scope of a visual aid, and could be significantly effective. Looking at Fig 3, for example, it is clear the visual aid can help the user get the attachment position of the example removably attachable arm portion attachment good, for their needs. For example, if the user has attached the removably attachable arm portion attachment in the position shown in Fig 3, but feels the arm portion is just slightly too long, they may choose to adjust the attachment position of the removably attachable arm portion attachment so that it is level with (or perhaps slightly higher than) the example bottom visual aid element, (which is a line, in the example). They could then use the connector 20a, to attach the removably attachable arm portion attachment to the securing portion. (It should be stated, there may be situations where a user, if they have the removably attachable arm portion attachment attached with a connector 20a, may not need to fully remove the connector 20a, (Ie may not need to detach the connector from being the removably attachable arm portion attachment and the securing portion). For example, they could keep the connector 20a attached to the one or the other, (ie the removably attachable arm portion attachment or the securing portion), and could then adjust position of the removably attachable arm portion attachment, and then reattach the connector 20a to whichever of the removably attachable arm portion attachment or the securing portion that they had detached the connector 20a from). The visual aid could be provided in various ways. For example, it may not be a different 'part’ and may just be differently coloured. (For example, imagining, for example, that the area of the wearable apparatus where the visual aid in Fig 3 is provided is generally black, for example, the example visual aid element(s) could be white, but be the same 'part' as the area where they are provided. In other embodiments, a visual aid element(s) may be provided by way of a separate 'part(s)’. For example, looking at the example of Fig 3, the example visual aid element(s), (three visual aid elements being clearly visible in the view shown in Fig 3), could be separate part(s), (eg three pieces of material), and could then be attached. For example, they could be heat-bonded in place. Or they could be sewn / stitched in place, for example. Or glued, for example. (These are only given by way of example in terms of how attachment could be achieved, and various options and / or embodiments are possible, the examples being provided simply by way of example only). (Furthermore, any combination(s) of these methods of attachment may be provided / possible). (It should be stated, all this is possible if there is only one visual ain element- the example of there being a plurality of visual aid elements) is provided simply by way of example). (It should also be stated, more than one visual aid element could be provided wherein more than one visual aid element is provided together with another visual aid element(s), as a separate part. To explain, looking at Fig 3, for example, the example visual aid elements could be provided together as one separate part. For example, they could be provided as an attachment, (being provided / functioning as a ‘patch’, for example) that is then attached where they are shown attached in Fig 3, for example, (or at any position that is desired / relevant / appropriate). Thus more than one visual aid element can be provided as a single attachment. (And, as made clear, it should also be stated that visual aid elements could be provided as separate attachments, (rather than as a single attachment). (And any combination of these options is possible). Thus various options and / or embodiments are possible. A visual aim elements) could feasibly simply be provided by way of sewing, (ie by sewing simply of thread). Thus various options and / or embodiments are possible. It is thought to be significantly helpful for a visual aid element(s) to be a colour that stands out from the area is it provided / positioned. Being a different colour can be helpful in highlighting it, and therefore making it easier to see. Thus, broadly speaking, examples have been disclosed and described of wherein a visual aid utilizes different colouring. (It has been stated how this can be useful, to aid visibility). (It should be noted, Fig 5 shows clearly that there are two visual aids 21. (One is used for left-handed use, and one is used for right-handed use). However, it will be apparent, rather than two clearly delineated visual aids like this, the visual aids could ‘meet’, (and therefore be provided as a ‘single’ or ‘joined’ visual aid. For example, if the example aperture 28 in Fig 5, (which is provided in a ’slit’ shape, in the example, (simply by way of example only)), was not provided / present, it can be imagined that the example top ‘lines’ of the visual aid could go the whole way across, (provided as one line). It can be imagined that the example middle ‘lines’ of the visual aid could go the whole way across, (provided as one line). It can be imagined that the example lower 'lines’ of the visual aid could go the whole way across, (provided as one line). This would, of course, be within a scope of there being a visual aid. (It would also be within the scope of there being a visual aid for right-handed use; and a visual aid for left-handed use. Thus there could be a visual aid for right-handed use; and a visual aid for left-handed use; wherein the visual aids are provided separately, (with Fig 5 showing a clear example of this). But it should also be stated, there could be a visual aid for right-handed use; and a visual aid for left-handed use; wherein they are provided by way of one visual aid, (as has been described). (Another way of putting this might be a visual aid for right-handed use; and a visual aid for left-handed use; wherein they use at least one same visual aid element. (Both are within scope of wherein there is a visual aid for right-handed use; and a visual aid for left-handed use). (It is feasible a combination of delineation and non-delineation is provided, (ie where at least one visual aid element(s) is ‘shared’ by the visual aids for left-hand use and right handed use, and at least one visual aid element s) is not ‘shared’ by the visual aids for lefthand use and right handed use. Thus this supports the language "wherein they use at least one same visual aid element.”. And, (in an embodiment where the visual aids comprise more than one visual aid element), (as has been mentioned / alluded to), it is possible all the visual aid elements are 'shared’ by the visual aids for left-hand use and right handed use Preferably there is provided more than one said removably attachable arm portion attachment, of differing sizes, each said removably attachable arm portion attachment being interchangeably attachable to the securing portion. (And thus interchangeably usable). Preferably there is provided more than one said removably attachable arm portion attachment, of differing lengths, each said removably attachable arm portion attachment being interchangeably attachable to the securing portion. (And thus interchangeably usable). (Length, as will be explained, in one possible factor, in terms of being a different 'size'. ('Girth1, for example, is another)). To explain, an example removably attachable arm portion attachment 18 is clearly shown in Fig 2, for example. (And significant disclosure has been provided with reference to this). If it is imagined, however, (looking at Fig 2), that the same apparatus is worn by a different user, who has very long arms, it will be apparent they may ideally want the arm portion 12 to be longer. (It could even hinder their ability to throw the ball with their natural throwing action if the arm portion is too short). In such a situation, they may therefore be able to detach the removably attachable arm portion attachment 18, and then attach a different removably attachable arm portion attachment that is longer. Thus they can use a different removably attachable arm portion attachment, to suit their needs. The term 'more than one’ of course includes within its scope any number from 'two' or any more than two. There being more then one removably attachable arm portion attachment, of differing lengths, can be particularly useful if the wearable apparatus is being used in a teaching / training environment, where the wearer does not own the wearable apparatus, and where the teacher / trainer may be teaching / training many different people (of many different sizes) and therefore it may be highly desirable to be able to cater in this way for people with different length arms. (It should also be stated, there being more than one removably attachable arm portion attachment, of differing lengths, could be very useful if a person wants to own the wearable apparatus, (eg by buying it), and wants to make the wearable apparatus fit them as perfectly as possible. For example, they could try different sizes, and buy the one that fits them best). (Note: Preferably each removably attachable arm portion attachment that is longer in length is slightly larger in circumference / girth (for a portion or a whole of the arm portion attachment), (ie preferably circumference / girth increases (and decreases) as length increases (and decreases). However, it is feasible a removably attachable arm portion attachment(s) could be provided that is longer (than another removably attachable arm portion attachment(s)), but that has no increase in circumference / girth (of any portion or whole of the arm portion attachment). Thus various options and / or embodiments are possible. Furthermore, it should be stated, it is even feasible that a removably attachable arm portion attachment(s) could be provided where a portion or a whole of the removably attachable arm portion attachment is of greater circumference / girth (than another removably attachable arm portion attachment(s)), but where the removably attachable arm portion attachment is not longer. Such an embodiment could even be made bespokely, for example, eg for a sports professional, such as a major league baseball pitcher, for example. Thus various options and / or embodiments are possible. This has been made clear. (It should also be stated, the terms ‘circumference’ and ‘girth’ do not rely upon the shape of the arm portion (attachment) being generally cylindrical. Although the arm portion is preferably generally cylindrical, embodiments may be provided where the shape could, for example, be more cubic. However, it is preferred that the arm portion is generally cylindrical. (The same goes for the / a removably attachable arm portion attachment as is mentioned for the / an arm portion here, (ie preferably being generally cylindrical, but not limited to this). The examples shown are within a scope of wherein a portion or a whole of the arm portion (attachment) is generally cylindrical. The examples shown are within a scope of wherein at least half length of the arm portion (attachment) is generally cylindrical. The examples shown are within a scope of wherein at least two thirds length of the arm portion (attachment) is generally cylindrical. The examples shown are within a scope of wherein at least three quarters length of the arm portion (attachment) is generally cylindrical. (Note: length definitions can be considered to be 'in total’. Therefore if one third length of the arm portion (attachment) was generally cylindrical, and then there was a part that was not generally cylindrical, and then, (after the part that was not generally cylindrical), there was another one third length that was generally cylindrical), that would be within a scope of wherein (at least) two thirds length is generally cylindrical. Thus this has been made dear)). (It should be noted, in the example embodiment of Fig 2, there is shown an example portion 36. (And, as has been stated, this can be useful, to accommodate bigger / larger arms, (in terms of 'girth’ of arm). Example portion 26, (and the example embodiment provided), is simply one example of this, not limiting such disclosure / concept. Thus this has been made clear). Preferably there is provided more than one securing portion, of differing sizes, to which the / a removably attachable arm portion attachment(s) is removably attachable. As will be explained, it can be beneficial for there to be more than one securing portion, of differing sizes, to which the / a removably attachable arm portion attachment(s) is removably attachable, each said securing portion being interchangeably usable with said removably attachable arm portion attachment(s). It has already been mentioned how there being more than one removably attachable arm portion attachment may be useful. So the same can be said for if there is more than one securing portion. Again, then, looking at the example being worn in Fig 2, the example fits the user well. However, it will be known, people can be many different shapes and sizes. For example, a person may be of diminutive stature. On the other hand, a person may be significantly large in stature. On these grounds alone, it may be useful for there to be more than one securing portion, of differing sizes, to which the arm portion attachment is removably attachable. However, there are other considerations. For example, dimensions around the chest area for women, especially, can differ significantly. Comfort, (and generally fitting well), is an important consideration, (especially since constriction during the throwing action is undesirable for several reasons- eg affecting technique of the thrower, the apparatus ripping, etc, etc). Furthermore, fitting well can be an important factor in the securing portion 16 doing its job. In the embodiments shown, for example, if the securing portion 16 is too loose, it can lead to the arm portion being loose in the sense of too much movement up and down the arm of the user, for example. There could be too much movement around the shoulder area, for example. Thus there being provided more than one securing portion, of differing sizes, can be extremely useful / important. Looking then, at Fig 2, (in light of Figs 5 and 6), if there is provided more than one securing portion, of differing sizes, a user / wearer can select which one fits them best. In the embodiments shown, (and other embodiments), this can be an important factor in the arm portion not moving too much, (especially in the process of throwing). It will be apparent, in the embodiment of Fig 2, (in light of Figs 5 and 6), that a user could select a different securing portion, and attach the / a removably attachable arm portion attachment to it. (Note: It will be apparent, in the example embodiments shown, that the securing portion 16 is provided with a portion of the arm portion, (see example portion 26), permanently attached. (This may, or may not, be the case in other embodiments). Nevertheless, whether a portion of the arm portion is permanently attached, if different sizes of securing portion are provided, that is within a scope of wherein more than one securing portion, of differing sizes, is provided). With regard to sizing of the securing portion, (and possible benefits), it has been alluded to that different ‘girth’ may be particularly useful. However, what may be referred to as vertical ‘height’ may also be an important consideration. (This may also be referred to as 'frontal height’). (Note: Rather than terms such as 'vertical’ or ‘frontal’ height, (with regard to the / a securing portion(s)), this may be referred to as ‘length’ (of the securing portion). Thus terms ‘length’ and ‘girth’ may be used, both with regard to the / an arm portion(s) / arm portion attachment(s), and with regard to securing portion(s)). Thus there may be provided more than one securing portion, of differing sizes, with regard to ‘girth’. Thus there may be provided more than one securing portion, of differing sizes, with regard to ‘height’. (And, of course, a different size may have both different ‘girth’ and different ‘height’. For example, a different size securing portion could be provided that is both greater in girth, and greater in ‘height’. However, any combination is possible. (And it should be stated, bespoke sizing for a particular person(s) may be possible))). (Note: Whilst example embodiments are shown of a securing portion that travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and wherein the securing portion also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso, there being provided more than one securing portion, of differing sizes, (to which the arm portion attachment is removably attachable), is not at all limited to such embodiments. (For example, a 'sling’-type embodiment is disclosed in the present application, (eg where a securing portion simply goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body). Even in such a basic embodiment, where the securing portion only goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body, for example, nevertheless, there may be provided more than one such securing portion, of differing sizes, (to which the arm portion attachment is removably attachable). Thus there being provided more than one said securing portion, of differing sizes, (to which the arm portion attachment is removably attachable), is not at all limited only to the embodiments shown in the Figures. It may be the case for any embodiment. (It may be the case for any 'securing portion’ design, of any type). Thus this has been made clear). (Preferably there is provided more than one said removably attachable arm portion attachment, of differing sizes, and there is provided more than one securing portion, of differing sizes, to which the removably attachable arm portion attachments are removably attachable. (Disclosure is herein provided of there being provided more than one said removably attachable arm portion attachment, of differing sizes, and there being provided more than one securing portion, of differing sizes, to which the removably attachable arm portion attachments are removably attachable, each said securing portion being interchangeably usable with each said removably attachable arm portion attachment. This therefore gives significant options for the user / wearer). (It should be stated, it has already been mentioned that a removably attachable arm portion attachment could be provided that does not span at least half length of the arm portion. For example, (looking at Fig 2, for example), if, in the example embodiment, the portion of the arm portion that comprises portion 40 and portion 19 was removably attachable, and rest of the arm portion 12 was not removably attachable, then that would be within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion. (But that it would not be within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion, and spanning at least half length of the arm portion). So it should be stated, there being provided more than one said removably attachable arm portion attachment, of differing sizes, each said removably attachable arm portion attachment being interchangeably attachable to the securing portion and thus interchangeably includes this within its scope, (ie where a removably attachable arm portion attachment could be provided that does not span at least half length of the arm portion). And this could still be useful / effective, (at least to an extent). For example, even such an embodiment of a removably attachable arm portion attachment as stated, (ie if / where merely the portion of the arm portion that comprises example portion 40 and example portion 19 was removably attachable), could be provided in different lengths, and this could thus change length of the arm portion. (Note: The term ‘size’ is not limited to ‘length’, as has bene mentioned / explained). However, clear disclosure is provided of a removably attachable arm portion attachment(s) 18 that span at least half length of the arm portion. (Of course, embodiments could be provided where no portion of the arm portion is removably attachable, and yet where there are different sizes available. For example, the securing portion and / or the arm portion could come in different sizes. For example, there could be small, medium, and large versions, where the securing portion is provided in three sizes in that way, (with no portion of the arm portion being removably attachable). And / or there could be different sizes with regard to length of the arm portion, (even where no portion of the arm portion is removably attachable), (eg Small, medium, and large length versions, for example, where the arm portion is three sizes in that way). Thus different sizes can be provided, whether or not there is any removable attachability with regard to a portion or a whole of the arm portion). (As has been stated, ‘size’ is not limited to being only about ‘length’. Different length and / or girth, with reference to the / an arm portion / arm portion attachment, for example, has been mentioned). (It should be stated, in the examples in the Figures, the securing portion 16 comes with a top portion 26 of the / an arm portion. This is perhaps best shown in Figs 5 and 6, but is also shown well in Fig 2, for example, as is also shown in the example embodiment of Figs 3 and 4. (See clearly in Fig 2 how this portion is part of the example arm portion 12). That end of the arm portion, (as opposed to the 'hand end’ of the arm portion), may be referred to as the 'shoulder end’ of the arm portion. It may be referred to as the ‘top end’ of the arm portion. Nevertheless, what is shown in Figs 5 and 6 clearly shows an embodiment of a 'securing portion’ 16. And it should be stated, a securing portion could be provided that is not permanently attached to any part of the arm portion 12. For example, looking at Figs 5 and 6, the securing portion 16 could be provided without there being any top portion 26 of the / an arm portion 12. It could then be, for example, that the whole of the arm portion is removably attachable to the securing portion. Thus various options and / or embodiments are possible, and that is made clear here. It should also be stated, it has been stated, in the example embodiments, that the example removably attachable arm portion attachment 18 is removably attachable to the example securing portion 16. It is here made clear that this includes within its scope being removably attachable ‘directly’, and includes within its scope being removably attachable ‘indirectly’. To explain, in the example embodiments, we can say that the removably attachable arm portion attachment 18 is ‘removably attachable indirectly’ to the securing portion. What is meant / intended by this is that, in the examples, the removably attachable arm portion attachment 18 is removably attachable to the securing portion, but via the example top portion 26 of the arm portion, (ie with the top portion of the arm portion, (which is permanently attached to the example securing portion, in the examples), as an ‘intermediate feature(s)’. If there are any 'intermediate feature(s)’, then that is considered to be ‘indirect’ attachment. However, as stated, an embodiment can be provided where the / a securing portion is not permanently attached to any portion of the arm portion. Imagining then that the whole arm portion is then removably attachable to the securing portion, (which could be an example of a removably attachable arm portion attachment that comprises the whole of the arm portion), then that would be an example of where the removably attachable arm portion attachment, (which, in such an example, could simply be referred to as ‘the arm portion’), is removably attachable to the securing portion, 'directly'. Thus it is made clear that both ‘direct’ and ‘indirect’ attachment are considered to be within the scope of the term attachment, (and any relevant terms to do with the term ‘attached’, (eg such as 'removably attachable’, for example). This, (ie 'direct and ‘indirect’ attachment being within the scope of the term attachment / attached), applies for the whole of the present application, with respect to such terms, (ie attached / attachment, etc). Thus this has been made clear. (Note: In the embodiments shown, the example securing portion 16 comprises a 'torso portion’. (The 'torso’ of a person is here defined as the body, not including the arms, legs and head). (Thus, in the example of Fig 2, for example, it can be said that the user is wearing a torso portion). (Thus, in the embodiments shown, it can be said that the wearable apparatus comprises a ‘torso portion’). (In the examples shown, the wearable apparatus 10 comprises a torso portion and an arm portion. However, it should be stated that varying embodiments of a securing portion can be provided. For example, a ‘sling’-type embodiment will be disclosed, and it will even be disclosed that an embodiment of a securing portion that merely goes around the head of the user, (around a reverse side to the arm portion), would be within the scope of being a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, and thus the examples shown are provided by way of example only. (A statement(s) of invention is included in this application including disclosure / definition of a securing portion 'that travels around a reverse side of the user,... to secure the arm portion to the user’. It should be stated, if opportunity arises to define in a claim [a feature], (whatever that feature may be or may be defined as being), ‘that travels around a reverse side of the user,... to secure the arm portion to the user’, then the claim may be filed without using the term 'securing portion’, (if, as stated, definition that [the feature] 'travels around a reverse side of the user,... to secure the arm portion to the user’ is provided with [that feature]). And, as long as [that feature] is disclosed / supported in the present application, then that definition is deemed supported, and this is hereby made clear. (Of course, it should also be stated, applicant may, in such a situation, simply include definition in the claim of 'a securing portion, comprising [a feature] that travels around the reverse side of the user..., to secure the arm portion to the user’, or the like). (It is feasible, in other embodiments, that the wearable apparatus could comprise other (area) portion(s)- for example, it is feasible the wearable apparatus could comprise a head portion, (eg comprising a hood, for example). It is feasible the wearable apparatus could even comprise a legs portion, (functioning as a trousers area, with a leg portion for each leg). These are merely stated to show it is possible that further area portion(s) could be provided)). Preferably the arm portion is increasably and decreasably adjustable in length. (Figs 2,3 and 4 are within a scope of this). It has been shown that, in the example embodiment(s) shown, attachment position of the example removably attachable arm portion attachment 18 is adjustable, to adjust length of the arm portion 12. However, it should be stated, an arm portion 12 can be increasably and decreasably adjustable in length, even in an embodiment where there is not a removably attachable arm portion attachment. To explain, an embodiment(s) could be provided where no portion of the arm portion 12 is removably attachable, for example. However, there could be a hook-and-loop type solution, for example, where there is an area for attachment / securing eg high up on the arm portion. The arm portion could then be ‘crimpable’, and where when crimped, a securing area (hook-and-loop type) could be attached / secured to said area for attachment / securing eg high up on the arm portion. Thus by crimping the arm portion, and securing it when crimped (in the way described), the arm portion could be made less long, (Ie decreased in length). By crimping the arm portion less, (or even fully uncrimping it), the arm portion could be increased in length. Such a solution could be used, if so needed / desired, around more than half of the circumference of the arm portion, (or may not). The example provided of hook-and-loop type attachment is provided simply by way of example only, and various other options and / or embodiments are possible. For example, the solution could use attachable buttoning, (ie similar or same as what many / most duvet covers use for closing at their open end once put around a duvet. Thus there could be a buttoning element (eg high up on the arm portion, for example). There could then be one or more than one buttoning element that can 'mate’ / connect with said (eg high up on the arm portion, for example), to thus facilitate ‘crimping’, (and thus facilitate adjusting length of the arm portion). Thus various other options and / or embodiments are possible, and it is here made clear that the / an arm portion being increasably and decreasably adjustable in length is not limited to there being a removably attachable arm portion attachment, (eg as shown in the example(s) in the Figures). (Thus disclosure has been provided of wherein the arm portion is selectably adjustable in length). (It should be stated, the term increasably and decreasably adjustable in length clearly differentiates, for example, from an item of clothing where pulling on the arm portion of the item of clothing lengthens the arm portion of the item of clothing, (ie due to nature of the material the arm portion / item of clothing is made out of. Irrespective of any other reason(s) for why this is, this would not be within a scope of being ‘increasably and decreasably’ adjustable in length). Preferably a first portion of the securing portion 16 and another portion of the securing portion are releasably connectable. (It will be shown how this can be useful, for securing the securing portion around the user. (Thus this can be useful, in facilitating securing the securing portion around the user)). Example(s) is shown, of wherein the securing portion 16 comprises a front portion 22 for a front of the user; and a back portion 24 for a back of the user. Preferably a front portion 22 of the securing portion for a front of the user and a back portion 24 of the securing portion for a back of the user are releasably connectable. (This is within a scope of wherein a first portion of the securing portion 16 and another portion of the securing portion are releasably connectable). (Fig 2 shows this, in use, securing the example securing portion around the user). (The examples of Figs 2-6 are all examples within a scope of this, (although relevant connector(s) are not shown Figs 5 and 6, simply to provide more focus / clarity as to what is being shown with regard to the example securing portion, and therefore the front portion 22 and back portion 24 of the securing portion 16 are not shown connected in Figs 5 and 6 (with reference to how they are connected in Fig 2, for example). (Fig 2 shows an example front portion being worn around the front of the user. The example back portion cannot be seen, due to angle / view shown)). (Note: No undue limitation should be read onto the term 'first' with regard to the term ‘first portion’. It is simply used to differentiate from what is referred to as the ‘other’ portion. (The ‘other’ portion’ may be referred to as a ‘second’ portion). Thus, unless otherwise stated, no undue limitation should be read onto terms / adjectives ‘first’, ‘second’, ‘third’, etc. They are simply terms used to help in differentiating from other features, especially with reference to claim(s), where lack of differentiation can otherwise lead to antecedent issues / problems, (eg with lack of clarity of what feature(s) are being referred to). To make clear, the terms 'first’ (portion) and ‘second’ (portion) are used broadly, and are tantamount to saying ‘one’ (portion) and 'another / the other’ (portion). Thus any of the portions may be considered to be the / a ‘first’ (portion) and any other of the portions may be considered to be the / a ‘second’ (portion). Therefore the terms ‘first’ and 'second' are used broadly. Furthermore, use of the terms 'first’ [feature] and ‘second’ [feature] in no way precludes there being a ‘third’ [such feature], (and possibly a ‘fourth’ [such feature], etc, etc. Thus no undue limitation should be read onto use of the terms ‘first’ and ‘second’, (especially when used in a daim(s), for example. These are broad terms that are significantly unlimiting, and can be useful, (especially in a claim, for example)). (Note: In embodiments that can be used reversibly for both left handed throwing and for right handed throwing, it should be stated, the 'front portion’ for right-handed throwing, is then the ‘back portion’ for left-handed throwing. Nevertheless, (and generally put without consideration of left-handed throwing or right handed throwing), it can be said that the example securing portion(s) shown comprise a front portion, (for a front of the user) and a back portion (for a back of the user). In the figures, (and in the textual description provided generally), feature ‘22’ is described as the ‘front portion’. This is with reference to right-handed use (as shown in Fig 2). It will be apparent that, if used reversibly, (for left-handed use), feature 22 will be the 'back portion’. (So the same, (ie with reference to reversibility with respect to right-handed / left-handed use), for feature ‘24’ being described as the ‘back portion’)). Preferably the wearable apparatus comprises a connector 20b, to releasably connect a first portion of the securing portion to another portion of the securing portion, to connect the securing portion around the user, the connector being separately removably attachable to the first portion and to the other portion of the securing portion. (Note: It should be stated, this is within a scope, broadly speaking, of wherein two portions of the securing portion are releasably connectable, (to connect the securing portion around the user. Thus, disclosure is here clearly provided of wherein: two portions of the securing portion are releasably connectable, (to connect the securing portion around the user), (and this broad disdosure / definition / terminology is thus here provided and made dear)). This can be done without a ‘separate’ connector(s). (And it should be stated, (and irrespective of whether a connector(s) is ‘separate’ or not), broad terms such as 'connecting feature(s)’ or 'connecting portion’, or ‘connecting arrangement’ may be used. To explain, looking at Figs 5 and 6, if this embodiment was one where the front portion and back portion can releasably connect to each other, simply by virtue of them connecting due to (a portion or a whole of) the surfaces that meet being releasably connectable, (eg via hook-and-loop type securing / attachment), and if this was simply due to the front and back portions having surfaces that were made of material(s) that had such mating characteristics, in such case, it would be hard to see any ‘extra’ connecting features, (ie The connectability characteristics may not be as visible as if there was a ‘clip’ connector, for example, (eg if one of the front / back portions comprises a receiver, for example, and the other comprises a ‘received’ portion, (to be received by the receiver)). However, such an embodiment as mentioned, (where the front and back portions having surfacesZarea(s) that were made of material(s) that had such mating characteristics), would still be within a scope of where there is a connecting arrangement, (to facilitate (the features that are connected) being releasably connectable. Furthermore, any portion(s) / area(s) that has such characteristics, (of, in this example, ‘mating’ for hook-and-loop type securing / attachment), would be within the scope of being a 'connecting feature’. Furthermore, any portion(s) / area(s) that has such characteristics, (of, in this example, ‘mating’ for hook-and-loop type securing / attachment), would be within the scope of being a ‘connecting portion’). Thus this is made clear). (Any connecting arrangement may be provided / used). Even hook-and-loop type attachment, for example, can be done without a 'separate' connector(s). For example, there could be a hook-and-loop type area(s). Thus each portion could comprise a hook-and-loop type ‘area(s)’. These could thus ‘mate’. (These could be permanently attached, for example, (eg by sewing, and / or heat bonding, and / or any other way(s)). In the preferred embodiment(s), (as explored in the present application), the securing portion is made partially or wholly of neoprene. Neoprene allows for hook-and-loop type attachment. (This would be within the scope of comprising a hook-and-loop type area). Whilst examples are provided where a ‘separate’ connector(s) is also used, it is feasible embodiments could be provided, (eg made of neoprene), where a ‘separate’ connector is not used / provided, (ie where two portions releasably connect together, without a separate connector(s) being used. (This would, of course, be within a scope of wherein the wearable apparatus comprises a connecting arrangement, to facilitate two portions of the securing portion being releasably connectable. Thus this broad definition, (of a connecting arrangement, to facilitate two portions of the securing portion being releasably connectable), is clearly provided, and is clearly supported)). (In the preferred embodiments, neoprene is also used with regard to the arm portion, with regard to hook-and-loop type attachment. This is also within a scope of comprising a hook-and-loop type area. (The term 'fastening’ area(s) may be used. The term 'securing’ area(s) may be used). Thus, broadly speaking, disclosure has been provided of two portions of the securing portion being releasably connectable, (to connect the securing portion around the user, (not limited to use of a 'separate connector’. Any connecting arrangement may be used. Thus, broadly speaking, disclosure has been provided of wherein the securing portion comprises a connecting arrangement, to connect two portions of the securing portion, (to connect the securing portion around the user). (Thus disclosure has been provided of wherein there is provided a connecting arrangement, to connect two portions of the securing portion, (to connect the securing portion around the user). (Thus disclosure has been provided of wherein the wearable apparatus comprises a connecting arrangement, to connect two portions of the securing portion, (to connect the securing portion around the user). (If so desired, (eg in a claim(s)), the terms 'first portion’ and 'second portion’ may be used, (rather than the term ‘two portions’)). (An example(s) of wherein 'the wearable apparatus comprises a connector 20b, to releasably connect a first portion of the securing portion to another portion of the securing portion, to connect the securing portion around the user, the connector being separately removably attachable to the first portion and to the other portion of the securing portion’ is shown in the Figures, where the wearable apparatus comprises a connector 20b, to releasably connect the front portion and the back portion, the connector being separately removably attachable to the front portion and to the back portion. (Figs 2, 3 and 4 show good examples of this. The example of Figs 5 and 6 is also an example that functions in this way, but, as stated, the connector(s) is / are not shown in Figs 5 and 6, to provide more clarity and focus regarding the example securing portion shown). In Fig 2, the / an example connector(s) 20b is shown in action. To explain, in the example embodiment of Fig 2, the front portion 22 and the back portion 24 are releasably connectable. In the example embodiment, example connector 20b1 facilitates this. (Note: Whilst the ‘front portion’ and the 'back portion’ are mentioned here, (and releasable connection is shown generally as a 'side’ of the user), connecting a first portion of the securing portion to another portion of the securing portion, (to connect the securing portion around the user), is not limited to this, (and connection is not limited to being at the 'side’ of the user). For example, it is feasible an embodiment could be provided wherein the securing portion 16 ‘comes together’ at the front of the user, eg towards / around a middle, (eg close to the navel of the user), and connects there. Thus the example(s) is provided by way of example only), The wearable apparatus comprising a connector, to releasably connect a first portion of the securing portion to another portion of the securing portion, to connect the securing portion around the user, the connector being separately removably attachable to the first portion and to the other portion of the securing portion is disclosed broadly. Thus this has been made clear). (It should also be made clear, (as will be disclosed / explored in the present application), that a connector does not have to be ‘separate’. Embodiments of connecting arrangements will be explored where there is no ‘separate’ connector(s). As will be explored, connecting feature(s) can be 'incorporated’ / ’integrated', (rather than being ‘separate’). Thus when it is stated that 'an embodiment could be provided wherein the securing portion 16 ‘comes together’ at the front of the user, eg towards / around a middle, (eg close to the navel of the user), and connects there’, this does not require that there is a 'separate’ connector- any connecting arrangement may be provided). (Note: It will be noted that the term 'releasably connectable’ is used in the present application. It should be stated, (and made clear), that portions of the securing portion 16 being 'releasably connectable’ does not in wany way preclude those portions from also being permanently attached. For example, looking at the example of Fig 2, the back portion and the front portion of the example securing portion 16 are releasably connectable, (connector 20b1, for example, is playing its role in releasably connecting the back portion and the front portion generally at area X1). However, they are permanently attached generally at area X2. Thus this has been made clear. (Figs 5 and 6 also make clear that, in the example securing portion 16, the back portion and front portion are also permanently attached generally around the shoulder area, (which is an example of being permanently attached 'above an arm’). However, it should also be stated that releasable connection can occur between portions that are not permanently attached. For example, looking at the example of Fig 2, imagining an example where the front portion and back portion are not permanently attached, it will be apparent that releasable connection could be employed, (eg at multiple points / areas). (This concept / examples is provided simply by way of example only), Thus it is here made clear that portions being releasably connected may be carried out whether those portions are permanently attached, or not). (Broadly speaking, embodiments are provided wherein the wearable apparatus is configured for portions of the wearable apparatus to be releasably connected. Broadly speaking, embodiments are provided wherein the wearable apparatus is configured for portions of the securing portion to be releasably connected. (This could be described as being ‘configured’ for being releasably connectable, if so desired). (Broadly speaking, embodiments are provided wherein the wearable apparatus comprises a connecting arrangement(s), to facilitate portions of the wearable apparatus being releasably connected)). (Note: Looking at Fig 2, even an embodiment where the front portion and back portion of the example securing portion do not meet or overlap, if a (‘separate’) connector 'bridges the gap’, (with the result being that there is a securing portion that travels around the reverse side of the user), then that is within a scope of being a securing portion that travels around the reverse side of the user, (and any / all relevant 'connector(s)’ can be seen as a feature(s) of the securing portion, for example). It will be explored in the present application that, whilst connector(s) are shown in the Figures that are 'separate' connector(s), connecting feature(s) can be more 'integrated’ as part of the apparatus, (not being 'separate'), (eg a 'clip(s)’, for example, that may be permanently attached, for example). Thus 'separate' connector(s) can be seen as being features that are 'temporarily’ 'separate’. But, as shown with regard to example connector 20b1 in Fig 2, for example, it will be apparent that, if example front portion 22 and example back portion 24 did not ‘meet’ or 'overlap’, and if example connector 20b1 ‘bridges the gap’ between them, what is shown in Fig 2 is still clearly within a scope of where there is a securing portion that travels around the reverse side of the user, and that is plain and clear simply from looking at Fig 2. (Fig 2 may, or may not, be such an embodiment). (So this same thinking can be applied to any ‘separate’ connector, not limited to the example provided of example connector 20b1 in Fig 2, for example. (Thus, it could be said that the example arm portion (shown in Fig 2) comprises example connector 20a, for example. (Thus it could be said (and is here said) that the example securing portion (shown in Fig 2) comprises example connector 20b1, for example). (And so the same would be the case for example connector 20b2, if a connector 20b2 is provided). (Thus ‘separate’ connectors should not be discriminated against, compared to connecting features that are integrated into a feature(s) / provided as part of a feature(s) that they help connect). (In Fig 3, a dashed arrow is provided to denote a possible position example connector 20a could be used, (eg in line with what is shown in Fig 2, for example). (However, (having stated that "it could be said that the example arm portion (shown in Fig 2) comprises example connector 20a, for example”, it should be stated, it is feasible an embodiment(s) could be provided, for example, where the whole arm portion is provided by a removably attachable arm portion attachment, and a ‘separate’ connector, (similar / same in nature to connector 20a, for example), connects the arm portion and the securing portion. (Thus such a connector could be positioned generally around the shoulder, for example, (although it should be stated, (such) a connector could feasibly be positioned more on a lower side than an upper said, (and it should be stated, more than one (such) connector could be provided)). (Thus it is broadly stated that disclosure is provided within a scope of wherein the wearable apparatus comprises a separate connector, to connect the / a removably attachable arm portion attachment to the / a securing portion. (Thus this is stated broadly. Thus this is made clear)). (And as is stated and made clear in the present application, such connecting feature(s) could be ‘integrated’, rather than being provided ‘separate’ (to what is being connected)). Thus various options and / or embodiments are possible)). (Note: Whatever way(s) portions (of the wearable apparatus) are ‘connected’ releasably, this may be referred to as a ‘connecting arrangement’. It should be noted, the term ‘attach’ / ’attaching’ may be used, instead of ‘connect’ / ’connecting’. However, it is thought there may be times where use of the term ‘connect / ’connecting’ / ’connection’ may provide slightly more clarity, (or at least may perhaps slightly lessen the chance of misinterpretation), eg because portions that are permanently attached may also be releasably connectable, (eg the front portion and back portion of the securing portion, for example). However, as stated, the term 'attach’ / ’attaching’ may be used, instead of 'connect’ / ’connecting’, if desired, wanted, or needed. Thus a term such as ‘attachment arrangement’, (rather than 'connecting arrangement’), may feasibly be used. (In line with what is stated above, whatever way(s) portions (of the securing portion) are ’connected’ releasably, this may be referred to as a ‘connecting arrangement’. It should be noted, the term ‘attach’ / ’attaching’ may be used, instead of ‘connect’ / ’connecting’). Thus it can be broadly stated that, (looking at Fig 2, for example, there is provided a connecting arrangement for connecting the example removably attachable arm portion attachment to the example securing portion. (Thus an example is shown wherein the wearable apparatus comprises a connecting arrangement, to connect the removably attachable arm portion attachment to the example securing portion. (Thus an example is shown wherein the example removably attachable arm portion attachment is releasably connectable to the securing portion. (All disclosure provided with regard to the terms 'indirect' and ‘direct’ attachment is here relevant)). (In the example, the example connecting arrangement comprises example connector 20a. However, in other embodiments, a connecting arrangement need not comprise a ‘separate’ connector 20. For example, strap(s) (and / or any connecting feature(s)), may be incorporated’ / 'integrated’, (rather than being separate). (The examples shown, where there is a connector 20 that is separate to both portions that are connected together by the connector, is thus shown by way of example only, and is only one way of connecting. There are many ways of connecting , not limited to this. Any way(s) may be used, not limited to the examples shown and / or disclosed). (It will be apparent that various disclosure is provided in the present application of a connector, (to connect portions of the wearable apparatus together), where the connector is a ‘separate’ connector. (There may be more than one such connector). Whilst connectors are shown connecting particular portions of the wearable apparatus together, (eg connecting a removably attachable arm portion attachment to a securing portion, or connecting one portion of a securing portion to another portion of the securing portion), it will be apparent that a connector can be provided to connect any portion of the wearable apparatus to any other portion of the wearable apparatus. It should also be stated that the examples are provided simply by way of example only). Preferably the wearable apparatus utilizes hook-and-loop type attachment to removably attach the connector 20b to the first portion (of the securing portion) and to removably attach the connector to the other portion (of the securing portion). (This is the case in the examples shown). (Examples are shown within a scope of this, where the wearable apparatus utilizes hook-and-loop type attachment to removably attach the example connector 20b to the example front portion and to removably attach the example connector to the example back portion). To explain, (regarding the wearable apparatus utilizing hook-and-loop type attachment to releasably connect the example front portion 22 and the example back portion 24), looking at the example of Fig 2, for example, example connector 20b1, in the example, uses hook-and-loop type attachment, to attach to the example front portion of the securing portion. In the example, example connector 20b1 also uses hook-and-loop type attachment, to attach to the example back portion of the securing portion. In both examples, (provided simply by way of example only, and not limiting how hook-and-loop type attachment may function), both the example front portion and example back portion have a relatively smooth surface that is usable for hook-and-loop type attachment. (Broadly speaking, (irrespective of ‘smoothness’ (and irrespective of any ‘smoothness'-type definition), an outer side of the example securing portion is usable as a hook-and-loop type (securing) area. Thus, broadly speaking, this is within a scope of a portion or a whole of an outer side of the example securing portion being usable as a hook-and-loop type area). (What is shown, in the example(s), (provided by way of example only), is within a scope of wherein a portion or a whole of the example front portion of the example securing portion is usable as a hook-and-loop type area). (What is shown, in the example(s), (provided by way of example only), is within a scope of wherein a portion or a whole of the example back portion of the example securing portion is usable as a hook-and-loop type area). (In the example, they are made of neoprene. Neoprene is a material that can function for hook-and-loop type attachment. (In layman’s terms, it could be said that neoprene can be 'Velcro®- friendly’. In the example(s) shown, it is 'Velcro®- friendly’). However, it should be stated, neoprene is provided simply by way of example only. A portion or a whole of the securing portion may be made of material that is 'Velcro®- friendly’, (not limited to being neoprene). A portion or a whole of an outer side of the securing portion may be made of material that is 'Velcro®- friendly’, (not limited to being neoprene). A portion or a whole of the front portion may be made of material that is 'Velcro®- friendly’, (not limited to being neoprene). A portion or a whole of an outer side of the front portion may be made of material that is 'Velcro®-friendly’, (not limited to being neoprene). A portion or a whole of the back portion may be made of material that is 'Velcro®-friendly’, (not limited to being neoprene). A portion or a whole of an outer side of the back portion may be made of material that is ‘Velcro®- friendly’, (not limited to being neoprene). (Most or all of the securing portion and / or front portion and / or back portion may be made of material that is ‘Velcro®- friendly’, (not limited to being neoprene). (Most or all of an outer side of the securing portion and / or front portion and / or back portion may be made of material that is 'Velcro®- friendly’, (not limited to being neoprene). (A large amount or all of the securing portion being usable for hook-and-loop type attachment potentially has the big benefit of it being very easy for the user to connect things (via hook-and-loop type attachment / securing), without being limited to only being able to do this in very limited area(s) of the wearable apparatus. Neoprene, as stated, has this potential benefit. Neoprene also has the benefit of potentially having good qualities in terms of comfort. (For example, it can be provided not being too 'rigid’, for example). The examples shown, (provided simply by way of example), are within a scope of wherein a portion or a whole of an inner side and / or a portion or a whole of an outer side of the securing portion is usable for hook-and-loop type attachment. The examples shown, (provided simply by way of example), are within a scope of wherein most or all of an inner side and / or most or all of an outer side of the securing portion is usable for hook-and-loop type attachment. In the example, the securing portion provides a ‘smooth’ hook-and-loop type attachment / securing area(s). (In the examples, this is married to a ‘rougher’ smooth’ hook-and-loop type attachment / securing area(s). (In the example(s), the 'rougher’ smooth’ hook-and-loop type attachment / securing area(s) is provided by way of an example connector 20)). In the example, the example connector 20b1 has a ‘rougher’ surface / area, which engages with the front portion. The ‘rougher’ surface of the example connector 20b1 and the relatively ‘smoother’ surface of the front portion engage and ‘mate’, using ‘hook-and-loop type attachment, (often referred to, generically, in layman’s terms as 'Velcro® attachment). Thus fastening / attachment / connecting occurs. In the example, the same is the case for the example connector removably attaching to the example back portion of the example securing portion. Thus an example is provided / shown. In the example, the example connector 20 has a smoother outer surface, (Ie the surface visible in Fig 2). Thus it is within a scope of wherein a portion or a whole of the outer surface is 'smooth’, (or at least is 'smoother' than its hook-and-loop type area(s) on its inner side). Thus it is within a scope of wherein most or all of the outer surface is 'smooth1, (or at least is 'smoother' than its hook-and-loop type area(s) on its inner side). In the example, a whole of the inner side of the example connector 20 is a hook-and-loop type area. Thus this is an example of wherein a whole of the inner side of the example connector 20 is usable for hook-and-loop type attachment. However, in other embodiments, this may or may not be the case. In other embodiments, the connector 20 may, for example, comprise a hook-and-loop type area(s) for attaching to one portion (of the wearable apparatus), and another hook-and-loop type area(s) for attaching to another portion (of the wearable apparatus), (without the whole of the inner side of the example connector 20 is a hook-and-loop type area). (Both would nevertheless be within a scope of wherein a portion or a whole of the inner side of the connector is a usable for hook-and-loop type attachment). (Any such area(s) could be provided on the inner side of the connector, for example). Thus various options and / or embodiments are possible, and the examples are provided simply by way of example only. In the example, most or all of the outer side of the example securing portion is usable for hook-and-loop type attachment. However, in other embodiments, this may or may not be the case. (For example, Figs 5 and 6 allude, (intentionally or not, with regard to what is disclosed in Figs 5 and 6), to the possibility, (via feature(s) at example areas X3, X4, X5, and X6), of how hook-and-loop type attachment could be carried out, potentially with far less (amount) of the securing portion being usable for hook-and-loop type attachment. (Nevertheless, what is shown in Figs 5 and 6 is within a scope of wherein a portion or a whole of an outer side of the securing portion is usable for hook-and-loop type attachment)). (It should be stated, disclosure of a surface(s) / area(s) being 'rough(er)’ and a surface(s) / area(s) being 'smooth(er)’ is provided simply as an example, (Ie and being preferable and / or optional). It will be apparent, for example, that hook-and-loop attachment can be achieved, for example, with both mating surfaces / areas being 'rough’ for example. (Thus the example(s) are provided simply by way of example only). However, it should be noted, the wearable apparatus benefits from having smoother outer surfaces, in that the outer surfaces are less likely to 'catch’ on something. (Patch(es), (which may generally be referred to as 'addition(s)’), may be added. This could be done via the patch / addition having hook-and-loop type attachment feature(s), (eg a rough hook-and-loop type surface(s) / area(s), which can be secured to the securing portion, for example, (or any relevant area(s) of the apparatus, not limited to the securing portion. (As stated, disclosure of a surface(s) / area(s) being 'rough(er)’ and a surface(s) / area(s) being 'smooth(er)’ is provided simply as an example, (Ie and being preferable and / or optional). It will be apparent, for example, that hook-and-loop attachment can be achieved, for example, with both mating surfaces / areas being 'rough’ for example. Thus the example(s) are provided simply by way of example only)). In the example embodiment of Fig 2, (provided simply by way of example only), example connector 20a comprises a ‘rough’ hook-and-loop type surface(s) / area(s). (Thus it may be called a ‘rough’ hook-and-loop type connector). In the example embodiment of Fig 2, (provided simply by way of example only), example connector 20b 1 comprises a ‘rough’ hook-and-loop type surface(s) / area(s). (Thus it may be called a ‘rough’ hook-and-loop type connector). In the example embodiment of Fig 2, (provided simply by way of example only), example connector 20b2 comprises a ‘rough’ hook-and-loop type surface(s) / area(s). (Thus it may be called a ‘rough’ hook-and-loop type connector). The example shown is within a scope of wherein the / a connector(s) 20b utilizes hook-and-loop type attachment to removably attach to the / a first portion (of the securing portion) and to removably attach to the / (an) other portion (of the securing portion). (The example shown is within a scope of this, showing an example within a scope of wherein the / a connector(s) 20b utilizes hook-and-loop type attachment to removably attach to the front portion and to removably attach to the back portion). (Broadly speaking, examples are shown of wherein the / a connector 20 utilizes hook-and-loop type attachment to removably attach to the / a first portion (of the wearable apparatus) and to removably attach to the / (an) other portion (of the wearable apparatus). (It should be stated, it is feasible a connecting arrangement (and thus a connector) could be provided that utilizes hook-and-loop type attachment to removably attach to one of the portions (of the wearable apparatus), but not to the other. (For example, it could be permanently attached to the other portion (of the wearable apparatus), or could be removably attachable to the other portion (of the wearable apparatus) in some way other than through hook-and-loop type attachment). Thus various options and / or embodiments are possible. (It will be apparent that a significant array of options and / or embodiments are possible, for a connecting arrangement))). Preferably the first portion (of the securing portion) and the other portion (of the securing portion) are permanently connected around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso, and releasably connectable to secure the securing portion around the reverse side of the user. An example(s) within this scope are shown, within a scope of wherein the front portion 22 and the back portion 24 are permanently connected around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso, and releasably connectable to secure the securing portion around the reverse side of the user. (Figs 2,3 and 4 show good examples of this. The example of Figs 5 and 6 is also an example that functions in this way, but, as stated, the connector(s) is / are not shown in Figs 5 and 6, to provide more clarity and focus regarding the example securing portion shown). To explain, in Fig 2, for example, the example front portion 22 and the example back portion 24 of the example securing portion 16 are permanently connected generally at area X2. (They are permanently connected around the side wearing the arm portion). The example front portion 22 and the example back portion 24 of the example securing portion 16 are releasably connectable to secure the securing portion around the reverse side R1 of the user. It should be stated, being 'releasably connectable to secure the securing portion around the reverse side of the user’ does not require that connecting happens at the ‘side’ of the user. For example, connecting generally close to the navel, (ie more centrally), has been mentioned. Embodiments can be provided that achieve 'securing the securing portion around the reverse side of the user’ in this way. (And the ‘navel’ area is also just an example- any relevant / appropriate place(s) for releasably connecting (to achieve the result of securing the securing portion around the reverse side of the user), may be used). Thus various options and / or embodiments are possible. (The example shown in Fig 2, (provided simply by way of example only), is within a scope of wherein the example front portion and the example back portion are permanently connected around what could be called the 'arm portion side’ of the example securing portion, under the arm portion, and releasably connectable to secure the securing portion around the reverse side, (reverse with respect to what could be called the ‘arm portion side’ of the example securing portion). As stated, the example is provided simply by way of example only). (It should be stated, looking at the example of Fig 2, it is possible an embodiment(s) could be provided where the front portion 22 and back portion 24 are releasably connectable generally at area X2. This could be the case whether or not the front portion 22 and back portion 24 are releasably connectable generally at area X1, (or at any other area(s)). The securing portion 16 may be releasably connectable at any point(s), to travel around the user. Thus terminology, (regarding being 'releasably connectable’), is not limited to use of the terms 'front portion’ and 'back portion’. For example, an embodiment(s) could be provided where the securing portion releasably connects, around the user, at any point(s), (eg centrally, for example). For example, the securing portion may releasably connect, around the user, centrally, at a front of the user, for example. For example, the securing portion may releasably connect, around the user, centrally, at a back of the user, for example. It should also be stated, ‘connecting’ can be carried out without a 'separate’ connector(s). For example, hook-and-loop type securing area(s) can be incorporated / integrated onto the apparatus. For example, looking at Figs 5 and 6, it is feasible there could be a hook-and-loop type securing area generally at area X3, for example, and that there is a hook-and-loop type securing area generally at area X4, for example, where the hook-and-loop type securing areas marry, to this carrying out securing. (For example, looking at Figs 5 and 6, it is feasible there could be a hook-and-loop type securing area generally at area X5, for example, and a hook-and-loop type securing area generally at area X6, for example, where the hook-and-loop type securing areas marry, to this carrying out securing. This could be useful for similar function, but for left-handed use, and / or simply for allowing hook-and-loop type securing with one of the other overlapping portion being above or below the other, (ie both options). It should also be stated, rather than particular ('small’) area(s) being hook-and-loop type areas, it could be that whole surfaces, (or at least that very significant portions or a whole of) various areas are usable for hook-and-loop type securing. For example, if there is a hook-and-loop type area generally at area X3, for example, and then, for example, a portion or a whole of the back portion 24 (in terms of what is denoted in Fig 5), is of a nature that it can secure to the hook-and-loop type area generally at area X3, then that would be, of course, with a scope of being hook-and-loop type securing, (and said portion or whole of the back portion would be considered a hook-and-loop type securing area. (Similarly, rather than only the (relatively small) area X3, it is possible a (larger) portion or the whole of the front portion could be of a nature that allows for hook-and-loop type securing. If so, it too is considered to be a hook-and-loop type securing area). It will thus be apparent that such features can be incorporated / integrated, rather than being provided as ‘separate’ features. (It should also be stated, this is of course, (ie that ‘connecting’ can be carried out without a ‘separate’ connector(s)), is also relevant to attachment of the / a removably attachable arm portion attachment). Thus attachment / connecting / securing features can be incorporated / integrated. Thus various options and / or embodiments are possible). Furthermore, (with respect to the fact that ‘connecting’ can be carried out without a 'separate' connector), items such as fastener(s), strap(s), etc can be utilizes, and can be incorporated / integrated, (rather than being ‘separate’). Any such solutions that are regularly used for harnesses, backpacks, belts, etc, potentially may be usable (and thus may be provided). This is particularly relevant for releasable connecting / securing, (with reference to the securing portion. However, it is also relevant, for example, with regard to possible attachment of the / a removably attachable arm portion attachment. Thus various options and / or embodiments are possible, and the examples provided are provided simply by way of example only. (Note: It should be stated, with respect to two portions of the securing portion connecting releasably, it should be stated, the example(s) shown in the Figures are provided simply by way of example only. Portions of the (or any) securing portion may be connected anywhere, in any way. Thus portions of the (or any) securing portion may be connected anywhere, in any way, (with the result of being connected around the user). Thus portions of the (or any) securing portion may be releasably connected anywhere, in any way, (with the result of being connected around the reverse side of the user, for example). Thus portions of the (or any) securing portion may be releasably connected anywhere, in any way, (with the result of being connected around (any side(s)) of the user, for example). (Portions could be releasably connected, to connect the side wearing the arm portion, for example). Thus various options and / or embodiments are possible. (It should be stated, whilst, in the examples, (best shown in Fig 2, whilst being worn), the example front portion and the example back portion of the example securing portion are permanently connected around the side wearing the arm portion, this is provided simply by way of example only. In other embodiments, they may not be. For example, they could be releasably connectable generally / approximately at area X2, for example, (or at any place(s)). Thus various options and / or embodiments are possible). Preferably the securing portion is increasably and decreasably adjustable in tightness, around the user. In the example(s) shown, this is the case, since the securing portion can be wrapped around the user tighter (or less tightly), and the example connector 20b1 can then be used, to secure at that tightness. However, this is just one embodiment of how to achieve this. In other embodiments, fastener(s), and / or strap(s), and / or belt-type arrangement(s), etc might be provided and may be usable, to facilitate the securing portion being increasably and decreasably adjustable in tightness, incorporated / integrated hook-and-loop type securing may also be used to achieve this, (by securing relevant mating hook-and-loop type securing areas when the securing portion is more (or less) tight. Thus various options and / or embodiments are possible, and the securing portion being increasably and decreasably adjustable in tightness is not limited to use of 'separate’ connector(s). (Thus disclosure has been provided of wherein the securing portion is selectably adjustable in tightness). (Note: Whilst example embodiments are shown of a securing portion that travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and wherein the securing portion also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso, the securing portion being increasably and decreasably adjustable in tightness, around the user, is not at all limited to such embodiments. (For example, a 'sling’-type embodiment is disclosed in the present application, (eg where a securing portion simply goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body). Even in such a basic embodiment, where the securing portion only goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body, for example, nevertheless, the securing portion may be increasably and decreasably adjustable in tightness, around the user. Thus the securing portion being increasably and decreasably adjustable in tightness, around the user, is not at all limited only to the embodiments shown in the Figures. It may be the case for any embodiment. Thus this has been made clear). Preferably the securing portion is substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing. This can be important because, although most throwers are right handed, it would be desirable if the securing portion could also be substantially equally usable for left-handed throwing. (Furthermore, even right-handed throwers might want to practice left-handed throwing, and vice-versa). Disclosure is provided in the present application of wherein the securing portion is symmetrically designed, symmetrical from back-to-front, so that the securing portion is equally usable, with equal comfort, for both right-handed and left-handed throwing. (The example embodiment of Fig 2 is an example of this, for example). (This is the case in the examples shown. This is clear in Figs 3 and 4, (and is perhaps most clear in light of what is shown in Figs 5 and 6). Looking at the example in Fig 2, for example, the example is being used for right-handed throwing. However, in the example, the example can be reversed, and whether the same user wanted to use the securing portion for left-handed use, they could do this. (If the user is right-handed, they may be less concerned with using the securing portion for left-handed use. But if another user wants to use the apparatus, and if they are left-handed, for example, the example securing portion can be used in the same way, for left-handed throwing. (Note: the term 'substantially symmetrically’ requires a very high order of symmetry. However, it should be stated, because of features such as the / an armpit aperture(s) 30, for example, if there is just a slight lack of symmetry and 'symmetrical comfort’ (with reference to right-handed and left-handed use), it is possible slight adjustments can be made, to make it usable in terms of creating (almost) exactly the same comfort for right-handed and lefthanded use. Thus it could be made of god comfort in this way. However, the term 'substantially symmetrically’ does not include where there is a clear lack of symmetry such that one or the other of right-handed / left-handed use is clearly significantly less comfortable than the other. (Note: 'Comfort’ can be relevant to the apparatus actually being restrictive to throwing. Thus lack of symmetry can lead to ‘restriction’ of movement during throwing, which, of course, is highly undesirable for several reasons). The language used is intended not to include this within its scope. In other words, to be within this scope, the securing portion must be shaped so that the securing portion is substantially equally comfortable and usable both for right-handed and left-handed throwers, and is not merely ’serviceable / ’usable” for reverse use (but with clear added discomfort). Thus this is made clear). (The embodiments shown in the Figures can be said to be within a scope of wherein the securing portion is substantially symmetrically designed, back-to-front). (The embodiments shown in the Figures can be said to be within a scope of wherein the securing portion is substantially symmetrically designed, back-to-front, to facilitate equal use for both left-handed and right-handed throwing). (Note: Whilst example embodiments are shown of a securing portion that travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and wherein the securing portion also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso, the securing portion being substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing is not at all limited to such embodiments. (For example, a ‘sling’-type embodiment is disclosed in the present application, (eg where a securing portion simply goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body). Even in such a basic embodiment, where the securing portion only goes around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body, for example, nevertheless, the securing portion may be substantially symmetrically designed from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing. Thus the securing portion being increasably and decreasably adjustable in tightness, around the user, is not at all limited only to the embodiments shown in the Figures. It may be the case for any embodiment. Thus this has been made clear). (Note: With regard to being ‘substantially symmetrical7’substantially symmetrically designed’, all such disclosure provided in the present application relating to / being afforded to the / a securing portion is here now preferably afforded to the / an arm portion. Thus this has been stated. Thus this has been made clear). (Note: With regard to being 'substantially symmetrical7’substantially symmetrically designed’, all such disclosure provided in the present application relating to / being afforded to the / a securing portion is here now preferably afforded to the / an arm portion attachment. Thus this has been stated. Thus this has been made clear). (Note: With regard to being ‘substantially symmetrical7’substantially symmetrically designed’, all such disclosure provided in the present application relating to / being afforded to the / a securing portion is here now preferably afforded to the / a wearable apparatus. Thus disclosure of this has been provided, ‘holistically’, to the / a wearable apparatus. Thus this has been stated. Thus this has been made clear). (Note: The term 'substantially symmetrically designed’ (from back-to-front), (etc, or the like), is not intended to be limited by (ie include within its limitation) features that do not, once the / an apparatus / apparatus part(s) is worn, affect fit. For example, an embodiment where there is a tightening feature, (eg a tightening mechanism for tightening a strap(s), for example), only on one part / position of the / an apparatus / apparatus part(s), but where it is usable, (to tighten said strap(s)), whether the / an apparatus / apparatus part(s) is being worn for right-handed use or left-handed use, and where the / an apparatus / apparatus part(s) is substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing, would still be considered to be within a scope of being 'substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing’. Thus the term 'substantially symmetrically designed’ (from back-to-front), (etc, or the like), is not intended to be limited by what could be termed ‘peripheral’ features that do not, (once the apparatus is worn), affect fit. Thus this is made clear. However, even in embodiments where such a feature is provided, it is even feasible the wearable apparatus may be 'substantially symmetrically designed’, even with regard to such feature(s). Thus various options and / or embodiments are possible. (It should also be said, being 'symmetrically designed’ is not intended to take into account things such as branding, etc). It should also be stated, something can have these 'substantially symmetrical’ properties, not limited to differing materials. For example, looking at the embodiment of Fig 2, it is possible an embodiment of a securing portion could be provided where the front side is made of a particular material(s), (eg neoprene, for example), and the back side is made of (at least some) different material(s), (eg netting / webbing, for example). This can still be substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing. Thus the term 'substantially symmetrical’ is relating heavily to shape / fit. The nature of 'material constitution’ does not have to match. It can, nevertheless, be term 'substantially symmetrical’. It should also be stated, ‘thickness’ of material(s) does not have to be ‘symmetrical’, in order for something to be ‘substantially symmetrical’. Thus a front side of the / a securing portion could be thicker, (even possible significantly thicker, for example), than a back side of the securing portion. Nevertheless, even such an embodiment can be within the scope of being 'substantially symmetrical’. Thus, as stated, the term 'substantially symmetrical’ is relating heavily to shape / fit. (Having made these points with regard to the / a securing portion, so the points can be afforded to / are relevant to the / an arm portion, for example. Having made these points with regard to the / a securing portion, so the points can be afforded to / are relevant to the / an arm portion attachment, for example. Having made these points with regard to the / a securing portion, so the points can be afforded to / are relevant to the / a wearable apparatus, for example. Thus this has been made clear). (Note: If connecting feature(s) are involved, (eg a connector(s) as in the example of Fig 2, for example), even if a connector, in such an embodiment, was not greatly 'symmetrical’, this would not affect status / consideration as to the securing portion being substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing, if, for example, the example front portion and back portion of the securing portion comply, (with regard to being substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing)). (In Figs 5 and 6, (providedby way of example only), the example securing portions 16 are symmetrical either side of line S1, (line S1 only being depicted in Fig 6). Thus, in the example, line S1 is a line of symmetry. (The example embodiment is provided simply by way of example only)). In Fig 2, it is shown that there may be provided a connector(s) 20b2. (Thus, in an example where this is provided, this shows an example within a scope of wherein a securing portion also travels around a reverse side of the user, above the arm of the user. (Thus, in an example where this is provided, this shows an example within a scope of wherein a securing portion also travels around a reverse side of the user, higher than where a reverse side arm of the user is attached to the torso)). (Broadly speaking, the example is within a scope of being a securing portion that travels around at least one side of the user, above the arm of the user. (Thus disclosure is provided of an example within a scope of being a securing portion that travels around at least one side of the user, higher than where an arm of the user is attached to the torso)). Embodiments may be provided where the / a securing portion travels around both sides of the user, above the arm of the user. (Thus disclosure has been provided within a scope of wherein thee / a securing portion travels around both sides of the user, higher than where the arms of the user are attached to the torso)._(Looking at Fig 2, in an example where example connector(s) 20b2 is provided, this is within a scope of wherein the example securing portion travels around both sides of the user, above the arm of the user)._(Looking at Fig 2, in an example where example connector(s) 20b2 is provided, this is within a scope of wherein the example securing portion travels around both sides of the user, higher than where the arms of the user are attached to the torso). (Looking at Fig 2, in an example where example connector(s) 20b2 is provided, this is within a scope of wherein the example securing portion goes over both shoulders of the user). Looking at Fig 2, it can be seen, in this example, that this, (example connector 20b), can add even more stability / secureness. In the example, (provided simply by way of example only), the example connector 20b2 functions much like the example connector 20b1. The example connectors are considered to be features that the example securing portion 16 comprises. (It should be stated, it is feasible embodiment(s) could be provided that comprise a connector(s) 20b2, and do not comprise a connector(s) 20b1). (Note: Despite the particular example being alluded to / referred to several times, the / a securing portion travelling around a reverse side of the user, higher than where a reverse side arm of the user is attached to the torso is not at all limited to there being a separate connector to achieve this (and is not at all limited to there being a connecting feature of any sort to achieve this. The example is provided simply by way of example only, and it will be apparent that various different shapes / structures / designs are possible for the / a securing portion, (and which could travel around a reverse side of the user, higher than where a reverse side arm of the user is attached to the torso), not at all limited to the example provided / shown / mentioned, and not at all limited to any connecting feature(s) themselves travelling around a reverse side of the user, higher than where a reverse side arm of the user is attached to the torso. Thus the example is provided / mentioned / alluded to by way of example only. Various options and / or embodiments are possible). Whilst the example(s) shown in the Figures, (and the example shown in use in Fig 2, particularly), are good examples of a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user, it should be stated the examples are shown by way of example only. For example, in a much more basic embodiment, a 'sling’-type embodiment could be provided. To explain, it is known that, when a person damages (eg breaks) their arm, they are often put in a ‘sling’, and this generally involves a part that goes around the arm, with the sling then going around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body to the side of the injured arm. So, if an arm portion is provided, (the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion), and even if then a 'sling’-type configuration is provided, (eg, as said, going around the reverse side of the person, generally around the neck / shoulder area on the reverse side of their body), then this would be within a scope, nevertheless, of being 'a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user’. In such a case, the part going around the user’s body, (around the reverse side of the body, generally around the neck / shoulder area on the reverse side of their body), would be an example of a 'securing portion’. Thus this would be within scope of being 'a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user.’. Thus, (simply to help aid imagining of an example of such an embodiment), looking at the example of Fig 2, if only the arm portion attachment 18 was provided, and a connector 20b2 similar to that shown, which connects to the arm portion attachment, secures it to the user, and goes generally around the shoulder / neck of the user, (similarly, for example, as example connector 20b2 does in Fig 2), then that would be within the scope of being 'a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion Jo secure the arm portion to the user.’ (Of course, rather than the securing portion being provided by way of a ‘separate’ part, the arm portion and securing portion could be permanently connected, for example. (Embodiments could be provided where a portion(s) / part(s) of the securing portion is permanently connected to a portion or a whole of the arm portion, but where another portion(s) / part(s) of the securing portion is removably attachable to the arm portion. Thus various options and / or embodiments are possible). (What is described is simply one possible example of a 'sling’-type embodiment, and it will be apparent various options and / or embodiments are possible, not limited at all to the example given). However, there are potential negatives of such an embodiment, (ie a 'sling’-type embodiment). For example, it may not be nearly as successful in terms of securing the arm portion. Thus the arm portion may be able to move (eg slide up and down the arm) in a way that may negatively impact the user. (It may make them feel uncomfortable, for example, or even concerned that the arm portion may fly off their arm when they throw). A 'sling’-type embodiment may even fly off the user, (ie the whole wearable apparatus), when they throw. (The 'sling’-type securing portion may be more liable to ‘slip / slide’, for example, with the possible result of the arm portion itself moving (too much) or even flying off the arm of the user when they throw). And even if it is made tight (around the reverse side of the user, (and thus tight generally around the shoulder / neck of the user), this itself can create problems, since something pulling into the neck area could be extremely uncomfortable, and could hugely affect the user’s ability to throw with their normal technique. In fact, discomfort could be greatly increased during the actual throwing act as the ball being thrown could lead to the securing portion pulling even tighter around the neck of the user. Nevertheless, as stated, this would be within the scope of being 'a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user.’ To make this even clearer, if a user was wearing a head-band type item, and this was connected to an arm portion (for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion), that would also be within the scope of being 'a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user.’. In that case, the securing portion would be comprising the head-band type item, (and would clearly be within the scope of 'travelling around a reverse side of the user, reverse with respect to side wearing the arm portion”, (in this case, the reverse side of the head). However, again, this could cause issues. For example, it could pull on the head. This could be very uncomfortable. As stated, this could get even worse when the ball is actually thrown, causing more of a pulling action on the head. It could also potentially be highly susceptible to flying off the user, and / or falling out of place. (A head harness, (eg as worn by some rugby players, for example), may eliminate the potential problem of the securing portion flying off the user or out of place, but it is still thought this would be cumbersome, potentially uncomfortable, and could pull on the user’s head when the ball is thrown. To make clear, these embodiments are mentioned simply to state that they are within the scope of being 'a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user’. The example securing portion shown in Fig 2, for example, is thought to be significantly more effective. In fact, mention of such embodiments could be argued to highlight how effective the embodiment shown in Fig 2 is. In the example embodiment of Fig 5, it can clearly be seen that there is an example aperture 28. (Preferably there is provided an aperture 28). In the example, this can help the apparatus fit for people with different thickness of arms. Whilst, in the example, the example aperture 28 runs to the end of example portion 26, in other embodiments, it might not. For example, it could be an aperture that does not go to the end of portion 26. It may still provide at least some benefits in catering for people with arms that would otherwise perhaps be too tightly surrounded. It should also be stated, such a feature(s) may be provided, even in an embodiment(s) where no portion of the arm portion is removably attachable, (or where an arm portion attachment is not removably attachable so high up), (or even where the whole arm portion is removably attachable). Thus, whatever such embodiment is provided, an aperture(s) may be provided. As stated, this can help the apparatus cater for people whose arm would otherwise be too tightly surrounded. Thus various options and / or embodiments are possible. (Embodiments may, of course, be provided that do not comprise such an aperture(s) as aperture 28. The example(s) is provided by way of example only. Nevertheless, it has benefits, as have been explained). (It should be stated, the embodiments shown in Fig 2 and Figs 3 and 4 also comprise the / an aperture 28, but it is not visible due to angle / view shown). (Note: In the example(s), example aperture 28 is provided in a generally linear shape. (In the example shown in Figs 5 and 6, it is provided in what could be considered to be a ‘slit’ type shape). However, this is provided by way of example only, and it is feasible aperture 28 could be provided in any relevant shape. It could be provided in other shapes, and nevertheless be at least significantly effective. However, the shape shown in Figs 5 and 6 is a preferred shape. (Note, whilst an aperture is shown, (see feature 28), it should be stated, a similar or same effect could be achieved in another way(s). For example, where aperture 28 is shown, instead of an aperture, elastic material could be used, for example. ‘Webbing’ could be used, for example, allowing that area (the aperture / webbed area) to expand. All of these are possibilities, with regard to this part / area being able to expand. (‘Expanding’, here, is within a scope of ‘increasing’). 'Excess material’ could be provided there, for example. All of these are possibilities. Thus it is able to increase in size around the arm. This can be very useful, for larger / thicker arms, (ie with reference to ‘girth’ of the arm). Thus various options and / or embodiments are possible. Thus, broadly speaking, this is within a scope of wherein a portion or a whole of the arm portion is increasable in size (around the arm). (Examples have been provided within a scope of wherein a portion or a whole of the arm portion is expandable). (Terms such as ‘girth’ may be used. Terms such as ‘circumference’ may be used). It may thus be stated that what has been disclosed is within a scope of wherein size around the arm of a portion or a whole of the arm portion is increasable. (Examples have been disclosed within a scope of wherein size around the arm of a portion or a whole of the arm portion is expandable). (What has been disclosed is within a scope of wherein a portion or a whole of the arm portion is increasable, (in size, around the arm), above the elbow. (Examples have been disclosed within a scope of wherein a portion or a whole of the arm portion is expandable, (in size, around the arm), above the elbow)). (As stated, various options are possible for how to achieve this). (Example feature 28 can be said to be a ‘gap’. Example feature 28 can be said to be an 'opening’. (Both these terms are within a scope of the broad term 'aperture’). Even if 'webbing’ is provided where example aperture 28 is, (and even if 'excess material’ is provided where example aperture 28 is), it can still be said to be a 'gap’, (and can still be said to be an 'opening’), with the webbing / excess material simply acting as limiting feature(s) / factor(s) on how far the area can expand / increase. (Whilst ‘elastic material’ has been mentioned, an issue with elasticity is that it can become fairly ‘tight to the arm, in process of increasing / expanding. Tightness could be undesirable, with regard to negatively affecting comfort (and even movement) of the user). (When example connector 20a is used, it can even have the effect of ‘binding’ both sides of example aperture 28, (which, in the example, (provided by way of example only), is in the shape of a slit), together. Thus the connector can even play a role in creating a ‘tightening’ effect). Similarly, it can be seen, (best shown in Fig 6 and also well shown in Fig 5), that there is provided an aperture(s) 30. (Again, this is shown by way of example only, and embodiments can be provided where there is no aperture(s) 30. However, in the embodiment, it can be very helpful, (especially for comfort), for there to be an aperture(s) here. It can play an important role in allowing free and full movement of the arm. Thus it can be extremely important in allowing the user to carry out a normal throwing action. (Thus preferably there is provided an aperture 30). The example aperture 30 is shown in Fig 2. This can be very helpful for facilitating full mobility of the arm. The example aperture(s) 30 provided is provided generally in an armpit area of the user. (It may even be referred to as an 'armpit aperture(s)’). In the example embodiment, (provided simply by way of example only), it clearly creates a significant void between the example front portion and the example back portion of the example securing portion. What is shown is within a scope of wherein the securing portion comprises an aperture in an armpit area, under the arm portion 12. As stated, the example aperture 30, in the example, frees up full movement of the arm for the user. (In the example, the example aperture is within a scope of being an aperture that is at least two centimetre in at least one direction. In the example, the example aperture is within a scope of being an aperture that is at least two inches in at least one direction. In the example, the example aperture is within a scope of being an aperture that is at least five centimetres in at least one direction. In the example, the example aperture is within a scope of being an aperture that is at least three inches in at least one direction. In the example, the example aperture is within a scope of being an aperture that is at least seven and a half centimetres in at least one direction). Note, whilst an aperture is shown, (see feature 30), it should be stated, a similar or same effect could be achieved in another way(s). For example, where aperture 30 is shown, instead of an aperture, elastic material could be used, for example. ‘Webbing’ could be used, for example, allowing that area to expand. All of these are possibilities, with regard to this part / area being able to expand. (‘Expanding’, here, is within a scope of ‘increasing’). 'Excess material’ could be provided there, for example. All of these are possibilities. Thus it is able to increase in size around the arm. This can be very useful, for larger / thicker arms, (ie with reference to 'girth’ of the arm). Thus various options and / or embodiments are possible. Thus, broadly speaking, this is within a scope of wherein a portion or a whole of the arm portion is increasable in size (around the arm). (Examples have been provided within a scope of wherein a portion or a whole of the arm portion is expandable). (Terms such as ‘girth’ may be used. Terms such as ‘circumference’ may be used). It may thus be stated that what has been disclosed is within a scope of wherein size around the arm of a portion or a whole of the arm portion is increasable. (Examples have been disclosed within a scope of wherein size around the arm of a portion or a whole of the arm portion is expandable). (What has been disclosed is within a scope of wherein a portion or a whole of the arm portion is increasable, (in size, around the arm), above the elbow. (Examples have been disclosed within a scope of wherein a portion or a whole of the arm portion is expandable, (in size, around the arm), above the elbow)). (As stated, various options are possible for how to achieve this). In Fig 2, an optional feature(s) 35 is shown. Looking at feature 35a, in this example, there is provided a QR code here. This allows a person, (via the QR code), to quickly view information to explain how the apparatus works / should be used. (Video is one possible way such information could be provided. However, it should be said, providing information could be done in ways that do not include video- for example, it could simply direct to a webpage, for example. Thus merely written text, (or text with image(s)) could be provided, to help / inform). It will be known how computer devices, (eg a smartphone) can utilise a QR code, to be directed (to information). Thus a user could use a smartphone. They could scan the QR code, which directs to the information, (viewable on the smartphone, in this example). It is possible the securing portion 16 could comprise such a feature(s). (This is denoted by possible feature 35b, denoted in basic fashion in Fig 2). Feature(s) 35 may be provided by way of a 'patch’, for example. (This is the way that example feature 35a is provided, in the example of Fig 2, for example). (Note: In various places / parts of the present application, the term 'removably attachable arm portion attachment’ is used, (with reference to where a portion or a whole of the arm portion is provided by way of a 'removably attachable arm portion attachment’). It should be stated, if / wherever desired, the term 'at least a portion of the arm portion [being] removably attachable’ may be used, (ie The term 'at least a portion of the arm portion’ (with relevant definition relating to removable attachability) may be used). Thus where it is stated that the wearable apparatus comprises a ‘removably attachable arm portion attachment [that comprises the hand end of the arm portion]’, language of wherein 'at least a portion of the arm portion is removably attachable, [said at least a portion of the arm portion comprising the hand end of the arm portion]’ may be used, for example, (and vice versa)). (Various disclosure has been provided within a scope of wherein the wearable apparatus comprises a removably attachable arm portion attachment, removably attachable to the securing portion, the removably attachable arm portion attachment comprising the hand end of the arm portion). Various disclosure has been provided in the present application of connector(s) that is / are 'separate’ (from the things they connect together). As alluded to in the present application, this is provided by way of example only, and it will be known that connector(s) can be provided that are not ‘separate’ to both things that they connect together. (Thus it is made clear that a connecting arrangement can be provided, not limited to being provided by way of a connector(s) that is / are ‘separate’ (from the things they connect together). For example, a strap can be provided, (with the wearable apparatus comprising a connecting arrangement where one or both of the 'things’ that are connected comprise a connecting feature(s) that is not ‘separate’ from that ‘thing’, (and instead may be ‘incorporated’ / ’integrated’). For example, a strap could comprise a connecting feature(s), (eg a plastic deformable connect), (eg incorporated / integrated as part of the ‘thing / portion’ it is used for, to connect to another 'thing / portion'), with the other ‘thing / portion’ that it plays a role in connecting to, for example, then comprising, for example, a ‘receiver’, to receive a said connecting feature(s). (Note: in such an example, the ‘receiver’ would also be an example of (and would be within a scope of being) a connecting feature. In another example, one portion of the wearable apparatus may comprise a strap that comprise a hook-and-loop type area, (eg at or towards its end), which may be (incorporated / integrated as) part of the strap, (not being ‘separate’ from the strap). Another portion of the wearable apparatus may then comprise hook-and-loop type area that the hook-and-loop type area previously mentioned can 'mate' to, and this later mentioned hook-and-loop type area may, for example, not be ‘separate’ to said other portion of the wearable apparatus. (Something being ‘sewn’ to the / a thing / portion it helps to connect to another ‘thing / portion’, (or permanently attached in any way(s)), is within a scope of 'not being separate’). (Something being formed as one part with the / a thing / portion it helps to connect to another ‘thing / portion’ is within a scope of 'not being separate’. (For example, if a portion of the wearable apparatus is made out of a material that facilitates connection, (eg a material that is used for hook-and-loop type connecting), then the area(s) used, (with regard to that portion), for hook-and-loop type connecting is 'not separate’ (from that portion). Thus this has been made clear, and it is here stated that the present application has been at pains to make clear that any method of attaching / connecting can be provided. The examples provided / disclosed are provided simply by way of example. There are many, many ways that connecting / attachment can be achieved. For example, it has not been disclosed that a 'hook(s)’ could be used, (to facilitate connecting / attachment), which would be yet another at least feasible way to achieve connecting / attachment. Thus the examples are provided simply by way of example only, and that is here made clear. Various options and / or embodiments are possible, and this is made clear. (In the example embodiment of Fig 2, for example, example connector 20a is 'indirectly’ attached to the example securing portion 16. (This has been made clear, in light of disclosure relating to ‘direct’ and ‘indirect’ attachment)). (Note: It has been made clear at various points in the present application that an embodiment(s) of a wearable apparatus could be provided where there is not a removably attachable arm portion attachment, and where the securing portion and the whole of the arm portion are permanently connected. It should be stated, any feature(s) disclosed in the present application for an embodiment where there is a removably attachable arm portion attachment, (unless otherwise stated or not possible / relevant), may be provided for an embodiment where there is not a removably attachable arm portion attachment, (and vice versa). (For example, an example visual aid 21 is shown in the examples in the Figures, where there is a removably attachable arm portion attachment. But such a feature could be provided in an embodiment where the securing portion and the whole of the arm portion are permanently connected. (As alluded to, embodiments could be provided where ‘crimping’ is possible, to increase or decrease length of the arm portion. In such an embodiment(s), for example, a visual aid could still be of use, for example)). Thus this has been made clear, that various embodiments are possible, and feature(s) disclosed may be afforded to any embodiment, (where possible / relevant)). (Note: A significant amount of disclosure is provided, in the present application, relating to a 'front portion’ and a ‘back portion’ (of a securing portion). It should be stated, it is here stated that, whatever disclosure is afforded to a ‘front portion’ and a ‘back portion’ (of a securing portion), it may more generally be afforded to a (first) ‘portion’ (of a securing portion) and 'another portion’ (of the securing portion), (not at all limited to the definition of being a ‘front’ portion and a ‘back’ portion, (and, of course, including within its scope the (first) ‘portion’ and the other portion being a 'front' portion and a ‘back’ portion, and, (especially in light of this here statement), this broad terminology is deemed supported, (not at all limited to any limitation(s) that the terms ‘front portion’ and ‘back portion’ may create). Thus this is made very clear. Thus all disdosure / feature(s) afforded to a front portion and a back portion of a securing portion may more generally be afforded to the broad terms (first) ‘portion’ and ‘another portion’. (The term 'second portion’ may feasibly be used instead of the term 'another portion’). It should also here be stated that any disclosure that is afforded to a 'front portion’ (of a securing portion) may be more generally be afforded simply to a ‘portion’ (of the securing portion), (ie using simply the term ‘portion’), (not limited to having to use the term ‘front’ portion, (and not at all limited to any limitation(s) that the term 'front portion’ may create)). Similarly, it should also here be stated that any disclosure that is afforded to a 'back portion’ (of a securing portion) may be more generally be afforded simply to a ‘portion’ (of the securing portion), (ie using simply the term ‘portion’), (not limited to having to use the term ‘front’ portion, (and not at all limited to any limitation(s) that the term ‘back portion’ may create)). Thus this has been made clear. It is clear, therefore, that broad disclosure has been provided. (If desired, applicant reserves the right to add any statement that has been provided with reference to use of the term(s) 'front portion’ and / or 'back portion’, simply using the broad term(s) ‘portion’, (instead of 'front portion’ and / or 'back portion’). Such statements are supported, (especially in light of this here statement). Thus this has been made dear)). Whilst it will be apparent that various shapes and / or designs are possible, (not at all limited to the examples provided), and the examples are provided simply by way of example only, the examples shown in the Figures, (looking at Figs 2 and 3,4), are examples within a scope of wherein the apparatus does not comprise any finger portions. To explain, when one wears a glove, the glove tends to have portions that are specifically shaped to surround each finger. (Even ‘mitten’ type gloves tend to have a portion specifically shaped to surround the thumb, (which would therefore be within a scope of being a finger portion’)). Any such portion(s) that is specifically shaped to surround a finger may thus be referred to as a 'finger portion’. (The term ‘digit’ may be used, if desired). Thus it can be seen that, looking at Figs 2 and 3,4, there are no finger portions. (The example is within a scope of wherein the arm portion does not comprise any finger portions). (The example is within a scope of wherein the hand end does not comprise any finger portions). This differentiates, for example, from a space suit, for example, (or the like), which comprises finger portion(s). (In the example shown in Fig 2, where an example ball 15 is shown being held by the example hand of the example user, it can be seen how none of the fingers of the user, in the example, are individually surrounded. The fingers, in the example, are ‘free’, within the arm portion). Furthermore, (as has been disclosed), preferably, in use, there is a gap between where the user’s hand is, (holding the ball to be thrown), and the end, (internally), of the arm portion. (This could be referred to as an 'end space’). (This, again, differentiates from apparatuses that comprise finger portion(s)). One reason for this is to allow the user to release the ball from the hand, (when throwing), with the hand having space to fully release. If there was not such an ‘end space’, it could disrupt the action of release of the ball. This could therefore lead to the user not being able to fully carry out their normal throwing action, (particularly with respect to how the hand releases the ball). (For overarm throwing, the 'end space’ is preferably approximately five inches to six inches. However, this could increase significantly when a ball, having been thrown, impacts the hand end of the arm portion. For example, it could approximately double, for example. (For example, see Fig 9, where the 'end space’, (between the user’s hand and the end (internally), of the arm portion, could, for example, be approximately 12 inches in what is shown in Fig 9. (The ball is shown, in Fig 9, at moment of impacting the example end, (internally), of the example arm portion)._For under-arm throwing, the 'end space’ is preferably approximately three inches. (Excess flapping about may affect the thrower more with underarm throwing. This is why preferably the 'end space’ is less for underarm throwing). (Again, this could increase significantly when a ball, having been thrown, impacts the hand end of the arm portion. For example, it could approximately double, for example). (Note: Looking at the example of Fig 2 simply as an example, the user may be able to make this adjustment. For example, if they are doing underarm throwing and the 'end space’ is at about three inches, if they then want to do overarm throwing, they may then adjust length of the arm portion so that end space is more, (eg end space of approximately five to six inches). (And vice versa, if they switch from overarm throwing to underarm throwing). (It should also be stated, when first putting on the apparatus, they may adjust length of the arm portion, (if adjustment is needed). Thus they can adjust to try to get the end space that they want / is appropriate. (And, as stated, this (ie what they want / is appropriate) may be affected by what type of throwing they want to do)). Note: Definition that the arm portion is 'enclosed’ at the hand end, (to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion), does not require that there are no apertures at all. For example, netting, (that does not allow the ball through), to give an example, (eg similar or same to the example netting shown in Fig 2 that the example arm portion comprises), could feasibly be used at the hand end of the arm portion. It would clearly prevent the ball from exiting at the end of the arm portion, when thrown, and such an embodiment would clearly be considered to be (and would be) within the scope of the arm portion being ‘enclosed’ at the hand end. (to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion), (However, with regard to features like providing auditory feedback, such an embodiment may not be as effective, for example). (It should also be stated that it will be known that many materials, (such as fabric(s), for example) have small holes in them, for example. This does not preclude such materials from use (with regard to the hand end of the arm portion being enclosed, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion). For example woven fabrics tend to have small holes in them, (if looked at closely). This does not preclude their use, for example. Thus various options and / or embodiments are possible). (Disclosure is provided of examples of a securing portion that are within a scope of wherein portions of the securing portion are releasably connectable in a manner that facilitates the securing portion being increasably and decreasably adjustable in tightness, around the user. (In the examples shown, disconnecting is required, to adjust tightness. In other examples, adjusting tightness may be possible, without having to disconnect. For example, there could be a tightenable dial, which, with the portions connected, can be used, (eg rotating the dial), to tighten and untighten the securing portion around the user. Turning the dial could tighten and untighten (depending on direction turned) a cord element that is wound around the dial, for example, with the cord element being in relationship with the portions such that tightening of the cord element tightens the securing portion around the user, and untightening of the cord element tightens the securing portion around the user. Thus this is an example, (provided by way of example only), of wherein adjusting tightness may be possible, without having to disconnect portions of the securing portion (that could be releasable connected together). (Another example, (provided by way of example only), could be a slide element / arrangement, where an element can be slid to tighten or untighten (depending on direction slid) the securing portion around the user. This could, again, comprise a cord element(s), for example, attached to the slide element(s). (Thus various options and / or embodiments are possible)). (Disclosure is provided of examples that are within a scope of wherein a removably attachable arm portion attachment is removably attachable to a securing portion in a manner that facilitates the arm portion being increasably and decreasably adjustable in length). (In the examples shown, disconnecting is required, to adjust length. In other examples, adjusting length may be possible, without having to disconnect. (For example, an attachment mechanism could be provided where, whilst remaining attached to the securing portion, the removably attachable arm portion attachment could be slid up or down, to adjust length of the arm portion. (Even a rotatable ‘dial’, (as mentioned with regard to being a possible embodiment of how tightness of the / a securing portion could be adjusted, without having to disconnect, is feasible. However, it may be cumbersome for us regarding changing length of the / an arm portion). It should be stated, wherever disclosure is provided in the present application, where relevant, terms such as ‘configured (for / to)’, and / or 'shaped (for / to)’ may be used. For example, disclosure is provided in the present application, (relating to Fig 2, for example), of portions of the example securing portion being 'releasably connected’. If so desired, therefore, where relevant, language / definition may be provided, (eg in a claim(s)), that the example wearable apparatus / securing portion comprises portions that are 'configured' to be releasably connected, for example, (or language / definition may be used that the securing portion is ‘configured’ for portions of the securing portion to be releasably connected, for example). Thus, (where relevant (and if desired)), language / definition relating to being ‘configured’ (to / for), or being ‘shaped’ (to / for), (or being ‘shaped and configured’ (to / for)), may be used, to define what is shown and / or disclosed. (It should be stated, example(s) are provided in the present application, where material(s) portion(s) of the wearable apparatus is / are made out of are 'Velcro®-friendly’. (Neoprene is used as an example). This is / can be relevant both to the / a securing portion and / or the / an arm portion, which is here made clear. However, it should be stated, hook-and-loop type attachment is not limited to being carried out in this way. For example, hook-and-loop type attachment / securing area(s) can be attached. (For example, they can be ‘sewn’ in, in order to attach them. (In layman’s terms, the term 'woven in’ may be used, for example. (The term ‘attached vie sewing’)). Thus, for example, a hook-and-loop type attachment / securing area(s)could be attached (eg sewn into) the / a securing portion, for example. (As stated, in layman’s terms, the term 'woven in’ may be used, for example). Thus, for example, a hook-and-loop type attachment / securing area(s) could be attached (eg sewn into) the / an arm portion, for example. (As stated, in layman’s terms, the term 'woven in’ may be used, for example). Thus, for example, a hook-and-loop type attachment / securing area(s) could be attached (eg sewn into) the / a removably attachable arm portion attachment, for example. (As stated, in layman’s terms, the term 'woven in’ may be used, for example). Thus various options and / or embodiments are possible, and the examples shown are provided simply by way of example only). (In the examples shown in the Figures, the example torso portion, (provided simply by way of example only), travels around both sides of the user. In the examples, the example torso portion, (provided simply by way of example only), travels around both sides of the user, lower than where the (relevant) arm of the user is attached to the torso). (The example embodiments of Figs 2 and 3, 4 are within a scope of being a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion, to prevent a ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion, connected to the arm portion, that travels around a reverse side of the user, reverse with respect to side wearing the arm portion). Note: It is here stated, with regard to disclosure in the present application, any portions of the / an apparatus that are disclosed as being attached / connected together releasably could be permanently connected together, (and this includes within its scope being provided as one part, for example). This is here made clear. For example, looking at Fig 2, for example, portions of the example securing portion 16 are shown connected together, releasably, via example connector 20b1, for example, generally, in the example, at area X1, for example. In line with what is stated, these portions could be permanently connected. For example, they could be connected together, but in a way that is not releasable. (And furthermore, (as alluded to / mentioned), they could be one part, (and thus permanently connected). (In such embodiments, the user may out the securing portion on by sliding it over their head, for example). It should be stated, irrespective of how portions / things are disclosed in the present application with regard to ‘connection’, any of these options are always possible. Thus portions can be releasably connected. Thus such portions can be permanently connected. Thus various portions may be removably attachable. Thus such various portions may be permanently attached. Thus various options and / or embodiments are possible, and this is made clear here. (To give another example, in the example of Fig 2, for example, looking at the example front portion of the example, securing portion, for example, example connector 20b1 is removably attachable to the front portion of the securing portion. However, in another embodiment, it may be permanently attached to the front portion. (In the example of Fig 2, for example, example connector 20b1 is removably attachable to the back portion of the securing portion. However, in another embodiment, it may be permanently attached to the back portion. (Thus, in other embodiments, the example connector 20b1 may be permanently attached to the front portion and / or back portion). Thus various options and / or embodiments are possible. Thus this is made clear that, whichever option (with regard to connection) is disclosed, any option (with regard to connection) is possible. (It should be stated, various embodiments have been disclosed where the / an arm portion in no way compresses or constricts the arm. For example, Fig 2 shows an example within this scope. Thus an embodiment(s) can be provided where there is no constriction / compression of the arm. Thus an embodiment(s) can be provided where girth of the arm portion, along the whole of the arm, is greater than the arm of the wearer, (without relying on elasticity, for example). Thus embodiment(s) can be provided where there is no constriction / compression of the arm. (Of course, an embodiment(s) can be provided where there is constriction / compression of the arm, (anywhere(s) along the arm), if so desired. However, (looking at Fig 2 as a good example, for example), the example securing portion 16 secures the arm portion to the user, without ay need for the example arm portion itself constricting / compressing the arm of the wearer. It is thought this is beneficial for various reasons). (Fig 2 thus shows a good example, in use, of where the securing portion is keeping the arm portion in place). (Note: It has been stated in the present application that, according to one aspect of what is invented, there is provided a method of a ball being retained after having been thrown, comprising: a wearable apparatus being worn by a user, the wearable apparatus itself comprising: an arm portion, for a throwing arm of the user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user; the ball being held by the throwing arm of the user; the ball being thrown by the throwing arm of the user; and the ball being retained in the wearable apparatus after having been thrown by the user. It should be stated, if so desired, a claim may be provided that defines this in a more 'first person’ point of view. In line with this, there is thus provided: a method of retaining a ball after throwing the ball, comprising: wearing a wearable apparatus, the wearable apparatus itself comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user; holding the ball with the throwing arm; throwing the ball; and the ball being retained in the wearable apparatus after having been thrown. (In line with this, there are shown examples within a scope of being, (and thus disclosure is provided in the present application within a scope of wherein there is provided): a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user). (With regard to ‘the ball being retained in the wearable apparatus after having been thrown by the user’, Fig 2 provides good understanding of this, by virtue of what is shown. (It can clearly be seen, in the example of Fig 2, that, if the ball is thrown, it will be retained in the wearable apparatus after having been thrown, due to the arm portion being enclosed at a hand end of the arm portion)). (In the example of Fig 2, provided by way of example only), the ball is retained in the arm portion after having been thrown. Whilst it is technically feasible an embodiment(s) could be provided where the ball is able to escape the arm portion (after having been thrown), up the arm portion and then being retained in the securing portion, (which could be shaped / worn in such way that the ball cannot escape and thus is retained in the wearable apparatus after having been thrown by the user, albeit not limited to definitely having to be retained in the arm portion), it will be apparent that it is highly desirable for the ball to be retained in the arm portion, after having been thrown. Amongst other things, this can make it very easy for the user to then grab the ball again, and do another throw, if so desired). (In the example shown in Fig 2, for example, after having been thrown, the ball cannot escape the example arm portion. Therefore it does not go into the securing portion. (In the example, given how the example arm portion attachment 18 is attached, it will be clear that, after having been thrown, the ball cannot escape from the arm portion. However, it should be stated, even in embodiments where there is not a removably attachable arm portion attachment, nevertheless, it may be impossible, (after having been thrown), for the ball to escape from the arm portion. (For example, the arm portion may fit to the arm in such a way that there just is not room for the ball to travel out of it, into the securing portion. For example, generally near / around the shoulder area, the arm portion may fit the user in such a way that precludes the ball being able to get through (and out of the arm portion). Thus this has been made clear). (Disclosure has been provided within a scope of wherein the arm portion comprises a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion. (Disclosure has been provided relating to removably attaching the / a removably attachable arm portion attachment to the / a securing portion). (Note: It is here stated that, whenever disclosure is provided, in the present application, of there being a connector, to connect two portions of the / an apparatus, where the connector is a ‘separate’ connector, (separate to the two portions), a connector(s) that is not separate (not separate to one portion of the portions, or not separate to both portions) may be provided / used. Furthermore, broadly speaking, wherever, in the present application, disclosure is provided of there being a connector, to connect two portions of the / an apparatus, where the connector is a ‘separate’ connector, (separate to the two portions), any connecting arrangement may be provided. Thus various options and / or embodiments are possible. This is made clear in the present application). (Anywhere in the present application where connection utilizes hook-and-loop type attachment / securing may thus be referred to as a connecting arrangement, (to facilitate connecting), that utilizes hook-and-loop type attachment). (Ie Such language may be used)). According to one aspect of what is invented, there is provided a method of retaining a ball after throwing the ball, comprising: a wearable apparatus 10 being worn by a user, the wearable apparatus itself comprising: an arm portion 12, for a throwing arm of the user, the arm portion being enclosed at a hand end 14 of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion 16 that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user; the ball being held by the throwing arm of the user; the ball being thrown by the throwing arm of the user; and the ball being retained in the wearable apparatus after having been thrown. (The example(s) shown are shown by way of example only). An example ball 15 is shown being held by the user in the example of Fig 2. When the ball is thrown by the user, it is retained in the wearable apparatus. (Most preferably, it is retained in the arm portion 12 of the wearable apparatus, although it is feasible embodiments could be provided where the ball is able to exit the arm portion 12, (at the top / shoulder end of the arm portion), and nevertheless be retained in the wearable apparatus. (For example, the ball could exit the arm portion 12, (at the top / shoulder end of the arm portion), and, dependent on design of the securing portion, could be retained in the securing portion. This would be within scope of being 'retained in the wearable apparatus’. However, preferably the ball is retained in the arm portion. Thus the wearable apparatus may be designed so the ball cannot exit the arm portion, (at the top / shoulder end). For example, it may be designed so that, in use, there is not enough space for the ball to be able to exit the arm portion, (at the top / shoulder end). (Whether the 'not enough space’ is right at / dose to the end of the arm portion, (at the top end), or is further down the arm portion, (eg if, even around halfway along the arm portion, there is not enough space for the ball to ‘get through’ any higher up the arm portion), that is within scope of there not being enough space for the ball to be able to exit the arm portion, (at the top / shoulder end of the arm portion). (Note: The term ‘adjusf / ’adjustable’ / ’adjustability’ etc is used at various points in the present application. It should be stated, eg with reference to adjusting ‘length / girth / tightness’, that if a portion(s) must be subtracted or added (to decrease / increase ‘length / girth / tightness’), then this is not within a scope of being ‘adjustable’, (in ‘length / girth / tightness’). It is within the scope of ‘length / girth / tightness’ being ‘changed’, but is not within a scope of being ‘adjustable’. (And broad disclosure is here provided of ‘changing’, (not limited to ‘adjusting’). If a thing is 'adjustable' (in 'length / girth / tightness’, then that is within a scope of wherein ‘length / girth / tightness’ can be ‘changed’. Wherever adjustability (of ‘length / girth / tightness’) is disclosed, it is deemed to be an example of wherein 'length / girth / tightness’ can be changed. The broad term 'changed’ is supported and may be used (eg in a claim), not limited to there being 'adjustability’. Thus this is made clear). Thus it is here stated that disclosure is provided of wherein the arm portion can be changed in length. (Thus disclosure is here provided of wherein the / a method comprises changing length of the arm portion). Thus it is here stated that disclosure is provided of wherein tightness of the securing portion around the user can be changed. (Thus disclosure is here provided of wherein the / a method comprises changing tightness of the securing portion around the user). Thus it is here stated that disclosure is provided of wherein girth of the securing portion around the user ran be changed. (Thus disclosure is here provided of wherein the / a method comprises changing tightness of the securing portion around the user). To explain more about how ‘changing’ (of ‘length / girth / tightness’, or any relevant parameter(s)) is possible, not limited to 'adjusting’, looking at Fig 2, let us now imagine, looking generally around area X7, that there was provided, (eg initially separate to rest of the apparatus), a circumferential addable 'band’, for example, 5cm in length, for example, and able to be 'added’ generally at area X7. Let us imagine then, looking at the example of Fig 2, for example, that it could be added between the example arm portion attachment 18, and example portion 26. Let us imagine that those parts / portions (including the imagined 'circumferential band’) can then be connected / attached together, (in any way(s), (eg hook-and-loop type attachment, for example, and / or any other way(s)). The addition of this imagined example 'circumferential band’ would therefore increase the length of the arm portion. Similarly, if that example imagined ‘circumferential band’ was ‘subtracted’ (not being used to add length), then the length of the arm portion would ‘decrease’, (relative to when it is used to add length). Thus this would be an example of wherein length of the arm portion has been ’changed’. But this would not be considered to be 'adjusting’ length. Thus the term 'changing' is broader than 'adjusting’. The term ‘changing is fully supported in the present application. (Note: The term 'circumferential band’ is used, however, broader terms such as 'removable portion(s)’ may be used, and it should be stated, the term 'circumferential band’ is used simply by way of example only. A 'removable portion(s)’ could be provided, not limited to being shaped in such a way as mentioned- it may be any shape. It may not wholly go around the arm. It may not resemble an arm ‘band’. The example is provided simply by way of example only. Thus various options and / or embodiments are possible. (It should also be stated, it is possible there could be more than one 'removable portion(s)’). (It should also be stated that, whilst the example for 'changing' (not limited to adjusting) is here provided with reference to changing length of the arm portion, so the same is the case with reference to changing / adjusting tightness of the securing portion, (around the user). (And thus so the same is the case for changing / adjusting ‘girth’ of the securing portion. Thus, whilst various examples are provided in the present application of adjusting tightness of the securing portion (around the user), it should be stated, it is feasible that tightness could be ‘changed’ (not limited to being adjusted). For example, (similarly to as described with reference to changing length of the / an arm portion, there could be provided ‘removable portion(s)’ that can be added (and subtracted) to increase / decrease tightness of the securing portion around the user. Thus this has been disclosed and made clear). (Simply to aid understanding, a depiction of a ‘circumferential band’ (and thus of an example embodiment, (provided by way of example only), of a ‘removable portion’) is denoted in Fig 2, shown in dashed lines, with the feature number being 99). Thus disclosure has been providing of ‘changing’, (with disclosure explaining increasing and decreasing), not limited to ‘adjusting’. Thus this has been disclosed. (Note: The example shown in Fig 2, for example, (with regard to the arm portion being 'adjustable in length’), is within a scope of the arm portion being 'adjustable in length’. (In the example, the example connector connects example portions 18 and 26. The example connector 20a may be removed to do this and then re-attached. The act of removing and then re-attaching, in this example, is here not considered to be 'subtracting’ or 'adding' because the connector 20a, if removed, is only temporarily removed with a view to re-attaching it with it then, again, fulfilling its function of connecting portions 18 and 26. In other words, in the end result, in this example, it is always used. (It is not left detached, in the example)). Preferably the method comprises adjusting length of the arm portion by adjusting attachment position of the arm portion attachment. (This has been explained). Preferably there is provided more than one said removably attachable arm portion attachment, of differing size (eg length, but the term 'size’ is not limited to length, as has been explained), each said removably attachable arm portion attachment being interchangeably attachable to the securing portion and thus interchangeably usable. The method may thus comprise detaching a said arm portion attachment from the securing portion, and re-attaching a different said arm portion attachment, of differing size, to the securing portion. (It has been explained why this may be useful). (As has been stated with reference to 'changing’ / ’adjusting' (eg in 'length’ / ’tightness’, etc), it should be stated, it should broadly be understood that acts such as 'detaching’ and / or 're-attaching' may be carried out whilst an item(s) / apparatus is being worn, or whilst it is not worn, (or whilst part(s) of the apparatus is being worn and part(s) is not). Thus all such options are possible, and are covered. Thus a claim that includes the term 'detaching' and / or the term 're-attaching’(or the like) is not limited to any of these options- all these options, (any option), is possible. Thus such act(s) can occur whilst item(s) / thing(s) are being worn. Thus such act(s) can occur whilst item(s) / things are not being worn). Thus such act(s) may feasibly be possible whilst one item(s) is being worn and another is not, for example. Thus various options and / or embodiments are possible and a claim that includes definition of such act(s) includes all possibilities within its scope. Thus this has been made clear). Preferably there is provided more than one said removably attachable arm portion attachment, of differing length, each said removably attachable arm portion attachment being interchangeably attachable to the securing portion and thus interchangeably usable. (The method may thus comprise detaching a said arm portion attachment from the securing portion, and re-attaching a different said arm portion attachment, of differing length, to the securing portion. (It has been explained why this may be useful). Preferably there is provided more than one said securing portion, of differing sizes, to which the (or any) arm portion attachment is removably attachable, each said securing portion being interchangeably usable with the arm portion attachment. The method may thus comprise detaching a said securing portion from the (or any) arm portion attachment, and re-attaching a different said securing portion, of differing size, to the (or any) arm portion attachment. (Another way this may be said is that the method may thus comprise detaching the arm portion attachment from a said securing portion, and re-attaching the arm portion attachment to a different said securing portion, of a differing size). However, it should be stated, it may be detaching (of the arm portion attachment / securing portion to each other is not required- for example, user may put the securing portion on first. If it is the ‘wrong’ size, they may take the securing portion off, and put a different one of, (off a different size). If that one is the right size, it may be that, only then, they attach the / an arm portion attachment. ((That said, it is possible they could put a securing portion on that already has the / a removably attachable arm portion attachment attached, and then feel the securing portion is the wrong size. In such situation, they may take off the securing portion (before or after detaching the arm portion attachment / securing portion from each other), detach the arm portion attachment / securing portion from each other, and then attach the arm portion attachment to a different securing portion (of a different size), and then out the securing portion on, (or pout the securing portion on and only then attach the arm portion attachment to it). (Any order of doing / achieving this is possible, the options for order of doing things disclosed being provided simply by way of example only). (It has been explained why this may be useful). Preferably the method comprises adjusting tightness of the securing portion around the user, the securing portion being increasably and decreasably adjustable in tightness, around the user. (Being adjustable in tightness can be useful. For example, one day, a user may be wearing just a shirt, for example. Another day, they may be wearing much thicker clothing. Also, this may be useful for the wearable apparatus to fit people of different sizes). Preferably the method comprises adjusting length of the arm portion, the arm portion being increasably and decreasably adjustable in length. (It has been explained why this may be useful). Preferably the method comprises using auditory feedback from sound of the ball impacting the hand end of the arm portion when thrown. This can be used to assess the throw. For example, sound of the ball impacting the hand end of the arm portion when thrown can be used to assess quality of a throw. For example, a more ‘compact’ sound can suggest a better quality throw. (This may be achieved, for example, from the ball impacting a certain area of the hand end of the arm portion. (Thus it could work not completely dissimilarly to a 'sweet spot’, which is a term used in many ball-striking sports. For example, in tennis, a tennis racquet is considered to have a 'sweet spot’, and the sound and feel of hitting the sweet spot is a phenomenon know to tennis players. (Hitting a ball with the sweet spot can also lead to a more powerful shot, (and / or even a more ‘controlled’ shot, eg when hitting a drop shot, or lob, or any particular spin shot, for example). Similarly, in sports like cricket and baseball, the bat in considered to have a 'sweet spot’, and it is clearly know to the user, (and often to those watching / hearing), when a ball has been hit with the sweet spot, (which is often referred to as 'good timing’). So, similarly, there may be an area of the hand end of the arm portion that functions not completely dissimilarly to a 'sweet spot’, perhaps creating a particular sound and / or feel. Thus it could be obvious to the user (and perhaps to person(s) watching / hearing), whether the throw has been timed well. Particular material(s) may be used, (for the hand end), potentially to aid in this process, (ie creating auditory feedback). This could help make it clear when the throw has been done well’. (It should be stated, for example, sound of the ball impacting the hand end of the arm portion when thrown can be used to assess power of a throw. Thus a more powerful throw may generate a more powerful sound when the ball impacts the hand end of the arm portion when thrown. Thus auditory feedback could be useful, in terms of assessing power of the throw. The user themselves can therefore benefit from using auditory feedback. Using auditory feedback could, it should be said, be useful for a trainer(s) who is assessing the thrower. It will be noted that, in the example embodiments, at least a portion of the arm portion can be seen through. For example, in the example of Fig 2, which shows a very good example being worn, it can be seen that generally the middle portion, (in the example), of the example arm portion 12 is made of netting. As has been mentioned, it can be seen that at least a portion of the user’s throwing arm 13 can be seen through this. As has been mentioned, this can be useful for analysis of technique. For example, a trainer could monitor arm position(s) of the user, when throwing. As has been mentioned, of particular attention may be position (eg bending) of the elbow. Thus potentially an elbow area / portion of the arm portion can be seen through. (As has been discussed, netting is just one example of material(s) / constitution that takes to being able to see through. (As has been mentioned, another example would be the use of transparent material(s), for example). Preferably, a portion or a whole of the throwing arm can be seen, (whilst the arm portion is worn). This can be used, for example, to analyse technique. For example, a relevant person(s) could analyse throwing technique. To give an example, this could be done live, for example, by a person other than the thrower, (eg a trainer, for example). Such a person may be a professional(s), (eg a professional throwing trainer and / or sports rehabilitation professional / specialist, for example). In another case, the throwing may be recorded by a device. The throwing technique could then be analysed via the / a recording(s). Thus the thrower themselves and / or any other person(s), (eg a professional(s), eg a throwing trainer and / or sports rehabilitation professional(s) / specialist(s), for example). The ability to see a portion or a whole of the elbow may be particularly important. For example, seeing how the elbow bends during throwing may be particularly important. Thus preferably the arm portion allows for being able to see of a portion or a whole of the elbow (of the throwing arm) of the user. (As mentioned in the present application, this, (Ie being able to see), could be achieved via a gap(s). As mentioned in the present application, this, (Ie being able to see), could be achieved via material(s) that are transparent. (Thus a portion or a whole of the arm portion could feasibly be transparent). It should be stated, a combination is possible, (Ie gap(s) and transparency). Thus various options and / or embodiments are possible. Thus the (or any) method may comprise seeing a portion or a whole of the throwing arm, during throwing. Thus the (or any) method may comprise seeing a portion or a whole of the elbow of the throwing arm, during throwing. Thus the (or any) method may comprise seeing bending of the elbow of the throwing arm of the user during throwing. ('During throwing’, as mentioned earlier here, does not preclude analysis after the act, (eg via a recording device). This could be done via 'frames’ ('freeze-frames’) being recorded and / or vis video footage. Thus a camera, (eg video camera) could be used). The term 'during throwing’ (eg with reference to bending of the elbow, for example, is referring simply to how the elbow bends during the act of throwing). (Whilst the elbow is of particular importance, the term 'a portion or a whole of the throwing arm’ is broad, and not limited to the elbow. It should also be stated, seeing of the elbow could be provided without the elbow being visible for all angles / sides. For example, just one angle / side, (eg seeing just of the inner side of the elbow joint, or just of the outer side of the elbow joint), could be enough to be able to analyse throwing technique appropriately. However, it is possible the elbow may be visible from multiple or all angles / sides. Thus various options and / or embodiments are possible). (It should also be stated, whilst seeing a portion or a whole of the elbow has been mentioned, any portion (or whole) of the arm may be see-able / viewable / seen. For example a portion or a whole of a wrist may be see-able / viewable / seen. For example, a portion or a whole of the arm below the elbow may be see-able / viewable / seen. For example, a portion or a whole of the arm above the elbow may be see-able / viewable / seen. (Any combination of these may be the case). It should also be stated, a portion or a whole of the shoulder may be see-able / viewable / seen. It should also be stated, bending of the shoulder (during the act of throwing) may be see-able / viewable / seen. Any combination of these things is possible. Thus this has been made clear). (Thus disclosure is provided of a portion or a whole of the throwing arm being visible during throwing. (Thus disclosure is provided of a portion or a whole of the throwing arm being visible whilst the arm portion is worn). (Fig 2 is an embodiment within a scope of wherein of a portion or a whole of the throwing arm is visible whilst the arm portion is worn, during throwing). The / a method may comprise analysing an elbow of the user, a portion or a whole of the elbow being visible when wearing the arm portion. (Disclosure is thus here provided of an elbow of the throwing arm of the user being analysed, a portion or a whole of the elbow being visible during throwing). (Fig 2 is an embodiment within a scope of wherein of a portion or a whole of the elbow is visible whilst the arm portion is worn, during throwing). As has been stated (in the present application), analysing the elbow may be of particular importance / usefulness. (Note: If so desired, terms such as ‘monitoring’ may be used, rather than 'analysing’. All such terms are supported). (As stated, such analysing could be done ‘live’, by a person(s) watching the thrower throwing, and / or the throwing could be recorded. If it is recorded, the recording could be used, to analyse the elbow, (and / or any aspects of the user’s throwing action and / or arm and / or body)), Monitoring of the arm, (which can broadly be described as monitoring throwing technique, (although the term 'throwing technique could also refer to other part(s) of the body, other than the arm), could potentially be done via video. Thus a throw could be recorded, and the footage could be analysed. Again, ability to see the throwing arm, (or at least to see a portion(s) of the throwing arm), could be very important / beneficial in this. As stated the elbow of the throwing arm may be particularly important / beneficial. Thus monitoring may take place. Thus analysis may take place. This can potentially be done by the thrower themselves, (eg vis video), and / or another person(s), (eg a trainer(s), and / or any relevant professional(s)). Disclosure has been / is provided in the present application within a scope of wherein the / a wearable apparatus is operable with there being no openings in the arm portion that are of a dimension that the ball can get / escape through. (Note: This is stated not taking into account any change(s) (eg pulling / deforming, etc) that may occur during the throwing action and especially from the ball impacting the hand end of the arm portion, after having been thrown. To explain, looking at Fig 9, it can be seen that quite a large 'gap’, (denoted as feature 50), has opened up. This is because the ball has been thrown, in the example, with quite a significant amount of force. This has had the effect of ‘pulling’ on the arm portion. (In the example, it has had the effect of ‘pulling’ on the example arm portion attachment. Example connector 20a is still doing its job, but it has led to gap 50 opening up). As alluded to, the ball impacting the hand end when thrown can have a significant amount of effect, with regard to such things. Other parts of the throwing action can potentially have an effect, (in terms of creating opening(s) / larger opening(s)). However, it is thought the ball impacting the hand end can have the greatest effect. Thus it may be possible for an embodiment to be provided that is within a scope of where the wearable apparatus is operable with there being no openings in the arm portion that are of a dimension that the ball can escape through, (even during the throwing action up to release of the ball, for example), but then, (eg similarly to as shown in Fig 9), the ball impacting the hand end of the arm portion can, (temporarily at that time / moment), open up opening(s), (eg potentially to quite significant size). However, it should be stated, looking at the example of Fig 9, opening 50 is not relevant in terms of the ball being able to escape because, in the example, the ball cannot escape out of the example removably attachable arm portion attachment 18 by itself, (eg after being thrown, (or at any time)). (Note: in the example, (especially if the user’s arm is skinny and / or the size (ref girth) of the removably attachable arm portion attachment is big for them, it is possible a person (eg the user or a different person), (eg especially if, (looking at Fig 9, for example), the example removably attachable arm portion attachment goes around the user’s arm elastically at its top, (by example opening 50, in the example / view shown in Fig 9), may be able to get part or all of their hand into the example removably attachable arm portion attachment, (whilst it is being worn by the user, eg as shown), and 'fish' the ball out, (due to the elasticity, in the example mentioned, for example). (This could be easier if the wearer holds their arm upwards, whilst this is being done). Thus disclosure has been provided of wherein the ball cannot escape by itself, but wherein the ball could feasibly be fished out). Note, for the sake of the present application, an arm portion comprising an opening that is of a shape and size (ie dimension) that the ball cannot escape through, but where the opening is elastically enlargeable so that it can be enlarged to a shape and size (ie dimension) that the ball can escape through), is still considered to be in line with being, (and not against the apparatus being) operable with there being no openings in the arm portion, (in use), that are of a dimension that the ball can escape through, because the ball cannot escape unless the opening is elastically adjusted (enlarged) by a user. (Thus this is in line with (and not against) being ‘operable in a mode wherein the ball cannot escape’). (And, it should be stated, disclosure of such an embodiment(s) is here provided). (Thus disclosure is also provided of method of removing a ball from the arm portion in such way, (and / or method of inputting the ball into the arm portion in such way). (It should also be stated that, if an embodiment is provided where the arm portion comprises an opening(s) that is of a dimension that the ball can escape through, but the opening(s) can be closed, in use, such that the apparatus can be used with the ball not being able to get through the opening(s), then that is in line with (and not against) being within a scope of being operable with there being no openings in the arm portion, in use, that are of a dimension that the ball can escape through. (Thus this is in line with (and not against) being ‘operable in a mode wherein the ball cannot escape’). (As stated previously, the term ‘aperture(s)' may be used, (eg wherever the term 'opening(s)’ is used). (The (or any) method may draw upon any disclosure provided in the present application, with reference to feature(s) / disclosure afforded to the / a wearable apparatus). (Note: In the present application, (with regard to wearing / using the wearable apparatus), the term ‘user’ may be used. Similarly, the term ‘wearer’ may be used. Either term may be used). (Note: The term 'increasably and decreasably’ (adjustable) is used in the present application, (eg the arm portion being ‘increasably and decreasably’ adjustable in length, and / or the securing portion being 'increasably and decreasably’ adjustable in tightness, around the user). It should be stated, this term does not mean (eg like a tightenable belt / strap) that you have to be able to adjust without breaking attachment / connection between things, (ie without disconnecting / detaching). For example, looking at Fig 2, for example, this is still considered to be an embodiment within scope of wherein the arm portion is 'increasably and 'decreasably’ adjustable in length. It is also considered to be an embodiment within scope of wherein the securing portion is 'increasably and 'decreasably' adjustable in tightness, around the user. In both cases, it utilizes hook-and-look type attachment. In both cases, hook-and-loop type attachment must be 'broken', to 'increasably' or 'decreasably' adjust. (Ie In the example, the example removably attachable arm portion attachment must be detached from the example the securing portion, to 'increasably' or ‘decreasably’ adjust length. And, in the example, the relevant example portions of the example securing portion must be disconnected, to 'increasably' or 'decreasably' adjust tightness). Nevertheless, such adjustment can be made. Thus it is within a scope of being 'increasably and decreasably' adjustable, (in the way(s) mentioned). (Nevertheless, as stated / alluded to, even in embodiments where portions are removably connected, embodiments can be provided where increasable and decreasable adjustment is possible, without disconnection / disconnecting. (For example, tightenable strap feature(s) can be provided that allow for adjustment, (eg to adjust length of the arm portion, (whether it be increasing length or decreasing length), eg to adjust tightness of the securing portion around the user, (whether it be increasing tightness or decreasing tightness), (eg by pulling on or loosening a strap(s), for example)), (the example of a strap(s) feature(s) being provided simply by way of example only). (And, it should be stated, increasable and decreasable adjustment can even be provided in embodiments without removable connection being relevant / provided. (For example, an arm portion being increasably and decreasably adjustable in length can be provided in an embodiment where no portion of the arm portion is removably attachable to the securing portion, for example. (An example of this, (provided simply by way of example only), would be via 'crimping' (as is disclosed in the present application, for example), with there being a fastening solution, (eg hook-and-loop type solution, and / or button type solution, for example, to secure when crimped). (And it should be stated, embodiments could be provided where a slide element(s) can be slid, to increase or decrease length of the arm portion, (depending on direction the slide element(s) is slid), and this could function even in an embodiment where no portion of the arm portion is removably attachable to the securing portion. (This is simply provided by way of example only). Thus various options and / or embodiments are possible). Similarly, a securing portion being increasably and decreasably adjustable in tightness around the user can feasibly be provided in an embodiment where the securing portion is not including / relying upon two portions being releasably connectable, (eg using hook-and-loop, (eg via a hook-and-loop ‘protrusion / ear’, for example), and / or via any tightening mechanism which can be utilized on an embodiment even where the securing portion is not including / relying upon two portions being releasably connectable, (eg the 'crimping' example alluded to, or simply a tightenable cord element, for example, that runs around the securing portion, for example, (even in an embodiment where there are not 'releasably connectable’ portions, (eg similar to many tracksuit trousers, for example, which often have a tightenable cord element that can be used to tighten the trousers around the waist of the user, and which in no way has( / relies on) two portions of the trousers being releasably connectable. (Such a cord element, (around waist of trousers), if often tied in a bow by the user / wearer, to have the trousers at the right tightness for them)). Thus various options and / or embodiments are possible. This has been made clear). (It should also be stated, so the same broadness is attributed to the term 'selectably adjustable’ (in length / tightness) as to the term ‘increasably and decreasably adjustable’ (in length / tightness). (Thus being 'selectably adjustable’ (in length / tightness) does not require that there is no disconnection / disconnecting, (in order to adjust length / tightness))). (It should be said, with regard to disclosure relating to attachment / connection, whatever disclosure / feature(s) is disclosed with reference to the / a securing portion, such disdosure / feature(s) may be afforded to the arm portion, (and vice versa). Thus this has been made clear). (It should also be said, with regard to disclosure relating to adjustment of tightness, whatever disclosure / feature(s) is disclosed with reference to the / a securing portion to facilitate this, such disclosure / feature(s) may be afforded to the arm portion, to facilitate adjustment of length, (and vice versa). Thus this has been made clear). (Note, in the present application there is various disclosure relating to ‘changing’ and 'adjusting' (eg 'length’ / ’tightness’, etc). It should be stated, it should broadly be understood that such ‘changing / adjusting’ may be carried out whilst an item(s) / apparatus is being worn, or whilst it is not worn, (or whilst part(s) of the apparatus is being worn and part(s) is not). Thus all such options are possible, and are covered. Thus a claim that includes the term 'changing' and / or the term ‘adjusting’ is not limited to any of of these options- all these options, (any option), is possible. Thus a claim that includes definition of such act(s) includes all possibilities within its scope. Thus this has been made clear). (Note: Wherever there is disclosure in the present application of a ‘connector’, (eg a ‘separate’ connector, such as example connector 20a, for example, in Fig 2, (or any attachment / connection feature(s)), it should be stated, broad terms may be used in a claim, such as 'connecting portion’ and / or 'connecting area’ (or the like), if so desired, and are not limited to 'separate' connector(s). (A broad term such as 'connecting feature(s)’ may be used (in a claim), for example, not limited to 'separate' connector(s)). For example, it will be understood that, (with reference to hook-and-loop type connection, for example), hook-and-loop type connection / securing areas can be 'incorporated’ / ’integrated’ into an item. Thus such an area(s) could be permanently attached. This could be done by being 'sewn in’, for example. (As alluded to elsewhere, in layman’s terms, the term 'woven in’ may be used, for example). And / or this could be done by being heat-bonded, for example. Thus various options and / or embodiments are possible, for how to achieve this. Furthermore, as has been mentioned in the present application, materials can be used that have such functionality, (without needing such feature(s) to be 'added’). For example, it is stated in the present application, with regard to the securing portion, (or any other part(s) of the wearable apparatus- eg any part(s) of the arm portion; eg any part(s) of the / an arm portion attachment, for example), that a material like neoprene can be used, and this is just one example of a material(s) that can have hook-and-loop type attachment properties. Thus various options and / or embodiments are possible, and when it comes to attachment / securing / connection etc, broad terms may be used, (eg in a claim(s)). Thus this has been made clear). (As has been alluded to in the present application, whilst the example of Fig 2 is within a scope of wherein a portion or a whole of the arm portion is removably attachable (to the securing portion), embodiment(s) could be provided where the whole of the arm portion is permanently connected to the securing portion. For example, embodiment(s) could be provided where the arm portion and the securing portion are one part, (rather than a portion or a whole of the arm portion being separate to / from the securing portion and needing to be attached). It is technically feasible they, (the arm portion and the securing portion), could be manufactured as one part. It should also be stated, this may not be the case, but it is possible that a portion or a whole of the arm portion could be permanently attached (eg via stitching) in such a way that the arm portion and the securing portion are provided as one part, (ie from the user’s point of view / experience). (Both of these are within a scope of the arm portion and the securing portion being permanently connected). Thus various options and / or embodiments are possible, and this has been made clear. (All the embodiments mentioned, (ie whether it be the example of Fig 2 where there is a removably attachable arm portion attachment, or embodiments where the arm portion and securing portion are permanently connected), are within a scope, in use, of the arm portion being connected to the securing portion). (Note: There is disclosure above relating to the arm portion and securing portion being provided as one part. It should be stated, for embodiments where there are 'separate' connector(s) (for the securing portion-eg such as example connector 20b1 in Fig 2, for example), the same (with regard to being provided as 'one part’) may be the case, and the / a term such as ‘not taking into account any separate connectors’ may be used. Thus, for example, the arm portion and the / an example securing part / item such as that shown in Fig 8, for example, may be provided as one part, and there might also then be provided a separate connector such as example connector 20b 1 (as shown in Fig 2, for example). This would be within a scope of wherein the arm portion and the securing portion are provided as one part, 'not taking into account any separate connectors’. Thus this is made clear). Looking at the example of Fig 2, it is clear the example embodiment is within a scope of wherein the example removably attachable arm portion attachment is removably attachable to the example securing portion via a separate connector. (Example separate connector 20a can be seen fulfilling this role in Fig 2). (Fig 3, for example, shows the clear ‘separate’ nature of the example connector 20a, (being ‘separate’ to both the example arm portion attachment and the example securing portion)). Fig 7 shows how there may be a plurality of removably attachable arm portion attachments, of differing sizes. Fig 7 shows two removably attachable arm portion attachments, of differing sizes. Even more, (of differing sizes), could be provided. (Each example arm portion attachment in Fig 7, for example, would be suitable to be removably attachable as the arm portion attachment for Fig 2, for example). In Fig 7, the example shown on the right is clearly larger than the example shown on the left. (It should be stated, whilst, in the example of Fig 7, the example on the right side is both longer (greater in length) and also broader, (greater in ‘girth’ / ’circumference’, (ie with reference to 'surrounding')), as has been stated, it is possible an arm portion attachment could be greater in length (longer) than another arm portion attachment, but whilst not being greater in ‘girth’ / ’circumference’. Similarly, it should be stated it is possible an arm portion attachment could be greater in ‘girth’ / ’circumference’ than another arm portion attachment, but whilst not being greater in length. Both are examples of nevertheless differing in size. (It is even possible an arm portion attachment could be provided that is lesser in ‘girth’ / ’circumference’ than another arm portion attachment, but whilst not being greater in length. And it is even an arm portion attachment could be lesser in length (longer) than another arm portion attachment, but whilst being greater in 'girth’ / ’circumference' than the other arm portion attachment. Again, all such options are nevertheless examples of differing in size)). Fig 8 shows how there may be a plurality of securing portions, of differing sizes. (As mentioned in the present application, example connector 20b1 in Fig 2, for example, is considered to be a feature of the example securing portion 16, and embodiments can be provided where the front portion and back portion of the securing portion, (in such example embodiments), do not overlap (or even ‘meet’) and where such a connector 'bridges the gap’, and that if this is the case, (eg if this were ethe case in Fig 2, for example), this would still be within a scope of wherein the securing portion travels around the ‘reverse side’ of the user. However, it has also been made clear that embodiments can be provided where the front portion and back portion do meet or overlap, and it has been made clear embodiments can be provided where there is no need for a ‘separate’ connectors. A connector(s) is not shown in Fig 8, (although connector(s) may be provided / used in such an embodiment(s) as shown in Fig 8. Thus, as has been explored, various options and / or embodiments are possible). (In Fig 8, (and also shown clearly in Figs 3 and 4), some dashes lines are shown. These simply represent possible sewing / stitch lines. However, in other embodiments, these may or may not be necessary. Thus they are simply shown / represented as a possible option. It should also be stated, in other embodiments, sewing / stitching may be utilized, but possibly in a different way and / or at differing position(s) / positioning. Thus various options and / or embodiments are possible, the examples being provided simply by way of example only). Note: It has been stated, in the present application, that there may be provided a plurality of securing portions, of differing sizes. It should be stated, looking at Fig 8, (and Figs 5 and 6), no ‘separate’ connector 20b is shown in these Figures. Of course, it has already been made dear in the present application, that embodiments can be provided not limited to there having to be a ‘separate’ connector(s). For example, connecting feature(s) can be provided that are ‘integrated’, (rather than being ‘separate’). Furthermore, embodiments can be provided where ‘connecting’ is not required- for example, looking at the example shown in Fig 2, for example, a torso portion could be provided that simply fits to the user, (eg the user placing it over their head, for example, (ie putting their head through it), and getting it generally into place similarly to as shown in Fig 2, for example), with it then either fitting well enough, (ie being tight enough), eg due to elasticity, or where it can be tightened, (eg via a belt and / or buckle(s) and / or strap(s) and / or dip(s) system, for example, (or any method / means / feature(s) at all to facilitate tightening, any tightening system being possible). Thus whilst the example securing portion of Fig 2 is shown requiring ‘connecting’, (and various other options and / or embodiments have been disdosed / explored, with regard to 'connecting’), it should be stated, embodiments can be provided where ‘connecting’ is not required. Imagining the item shown in Fig 8 (and Figs 5 and 6) to be an embodiment where no ‘separate’ connector(s) is required, thus the securing portion requires no such extra feature(s), (ie ‘separate’ connector(s)). However, it is here made clear, with reference to definition that there may be provided more than one securing portion, of differing sizes, (ie a plurality of securing portions, of differing sizes), then if, looking at Fig 8, a 'separate' connector 20b is required, (such as what is shown in Fig 2, looking at example connector 20b1, for example), then even if the same ‘separate’ connector (eg connector 20b 1, for example) is using the item shown on the left side in Fig 8, and when using the item shown on the right side in Fig 8, then even though the same separate connector is used, (and even though it has been stated in the present application that it can be said that the example securing portion (shown in Fig 2) comprises example connector 20b1 (ie an example ‘separate’ connector’), for example), then even if that same ‘separate’ connector is used both when using the smaller item shown to the left in Fig 8 and when using the larger item shown to the right in Fig 8, that is nevertheless considered to be within a scope of where there is provided a plurality of securing portions, of differing sizes. (And thus is considered to be within a scope of wherein there is provided more than one said securing portion, of differing sizes). (Of course, it is possible a different ‘separate’ connector could be used. However, it is made clear that, even when using the same ‘separate’ connector, what is described, (and what is shown in Fig 8, for example, especially in light of what is shown in Fig 2), would be considered to be within a scope of wherein there is provided a plurality of securing portions, of differing sizes. Thus this has been made clear). (Thus, it is stated, again, that a ‘separate’ connector feature should not be 'discriminated' against- for example, if the example items shown in Fig 8 had connecting features 'integrated’ for example, (being embodiment(s) that did not need any ‘separate’ connector, for example), then what is shown would clearly be within a scope of wherein a plurality of securing portions, of differing sizes, are provided, etc). (And it has also been made clear that it should also be stated that it is feasible a different ‘separate’ connector could be provided / used, when using the different sized items shown in Fig 8, for example). For example, a ‘separate’ connector that is a different shape and / or size could be provided / used, for example. (Eg a different ‘separate’ connector that is a different length could be provided / used, for example). In line with the fact that it has been stated, (looking at Fig 8, for example), that even if the same ‘separate’ connector is used, what is shown in Fig 8 is still considered to be within a scope of wherein more than one securing portion, of differing sizes, is provided, what is shown eg in Fig 5 and what is shown eg in Fig 6 is often referred to, in the present application, as the / a 'securing portion’. Nevertheless, as stated, in many embodiments, the securing portion may also comprise a ‘separate’ connector(s), (although it has been stated at length that any connecting arrangement may be provided, (not limited at all to there being a ‘separate’ connector(s)), and it has also been made clear that embodiments can be provided where no connecting arrangement is provided / needed). (Whilst it has been made clear that, even if the same ‘separate’ connector is used both when using the smaller item shown to the left in Fig 8 and when using the larger item shown to the right in Fig 8, that is nevertheless considered to be within a scope of where there is provided a plurality of securing portions, of differing sizes, we reserve the right to use other language, if so desired, eg that there may be provided more than one 'portion or whole’ of the securing portion, of differing sizes, (for example). (Or, (in other example language, for example), that, with reference to the securing portion 'without consideration of any separate connector(s)’, there may be provided a plurality of securing portions, (ie more than one securing portion), of differing sizes, etc). (It should also be stated, we reserve the right to use language, (and this is clearly supported), of wherein there is provided a plurality of items, of differing sizes, that each comprise a front portion, (see example front portions 22 in the Figures) and a back portion, (see example back portions 24 in the Figures). This has clearly been disclosed. However, it should be stated, the examples shown in the Figures are provided simply by way of example only, and it has been made clear in the present application that widely varying embodiments of a 'securing portion’ may be provided, not at all limited to the examples shown. Thus this has been made clear). (It should also be stated, with regard to there being provided more than one securing portion, of differing sizes, terms such as ’’without consideration of / for any connecting features” or "without taking into account any connecting features” (or the like) may be used. To explain, looking at the embodiment of Fig 2, in this embodiment there is a connector 20b1. (Disclosure has been provided with regard to this being a ‘separate’ connector). With regard to such an embodiment, (ie where there is a 'separate’ connector), if it is stated that there is provided more than one securing portion, of differing size, ‘not taking into account any connecting features’, then that refers, (with reference to differing size) to the ‘vest-type’ portion in the embodiment shown, irrespective for consideration for the example connector 20b. (ie Irrespective of whether the same ‘separate’ connector is used, or a different ‘separate’ connector is used (and irrespective, (if a different connector is used), of whether the different connector is the same size or a differing size). And it should be stated, this is only explaining what a term such as "without taking into account any connecting features” means, with reference to an embodiment, (looking at Fig 2), where there is a ‘separate’ connector. It also applies for embodiments where there are connecting features that are not ‘separate’. Thus, looking at Fig 2, if, rather than using example connector 20b1 (as shown / depicted in Fig 3, for example), there were connecting feature(s) that are ‘integrated’, (rather than being separate), in such an embodiment, 'not taking into account any connecting features’, then refers, (with reference to differing size) to the 'vest-type’ portion in the embodiment shown, irrespective of consideration of any connecting features. (As has been stated, connecting features such as buckle(s) / clip(s) / strap(s) etc can be provided). Thus this has been made clear. (It should also be stated that it has been made clear, (and it is here made clear), that embodiments can be provided without any connecting features. (It should also be stated that it has been made clear that embodiments can be provided without any connecting features, (with regard to the securing portion)). (In Fig 8, example ‘front portion is denoted with the feature number ‘22’ eg to be in line with how other similar Figures are numbered, (eg see Figs 5 and 6). In the example of Fig 8, there is also a ‘back’ portion 24, but this cannot be seen due to the front portion blocking the ‘back’ portion from view. (Please see Figs 5 and 6, for example, that are more revealing of a similar or same embodiment). (Example(s) are shown within a scope of wherein the arm portion comprises a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion). According to another aspect of what is invented, there is provided: a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion. (Note: According to this aspect of what is invented, the ‘arm portion’ may be the whole of the apparatus. Thus the term ‘portion’, (with respect to the term ‘arm portion’), should not be seen as overly limiting, for example and should not be seen as meaning that there must be other ‘portion(s)7’part(s)’. Nevertheless, we reserve the right to structure a claim, (relating to this aspect of what is invented) differently, if so desired). According to this aspect of what is invented, the arm portion may or may not be a removably attachable arm portion attachment, (removably attachable to a securing portion, for example). Thus various options and / or embodiments are possible. According to this aspect, significant ‘length’ is not required. For example, an apparatus may be provided in accordance with what has been defined, (with respect to this aspect of what is invented), where the apparatus only goes up to the wrist of the user, (and does not go further up the arm, for example). (The apparatus may use tightness / constrainment in order to stay on the user, (eg during the act of throwing). For example, it may comprise an elastic portion(s) / part(s). For example, it may be elastic around the wrist of the user, (and / or any part(s) of the arm of the user). This may help it stay tight enough to help prevent it from flying off the user when the user throws. (This is just one example of ‘tightness / constrainment’ in order to stay on the user). (According to this aspect, there may or may not be a securing portion that travels around a reverse side of the user. (It is not even required to be the length of half of the arm of the wearer, for example)). As stated, according to this aspect, there may or may not be a securing portion that travels around a reverse side of the user. According to this aspect, the arm portion may even (or may not) utilize tightness / compression on / of the arm, (to prevent falling off the user’s arm, (eg especially in the act of throwing, for example). Thus various options and / or embodiments are possible. (This aspect of what is invented may benefit from (and be afforded) any disclosure provided in the present application relating to any other aspect of what is invented, (eg as preferable and / or optional features). (It is here made clear that this aspect may draw upon any of the feature(s) / definition of any of the other aspect(s) of what is invented. Thus any disclosure, with regard to any of the other aspect(s) of what is invented may be afforded to this aspect, and this is here made clear)). Disclosure has been provided in the present application of: a wearable apparatus for retaining a ball when throwing the ball, comprising: an arm portion, for a throwing arm of a user, the arm portion being enclosed at a hand end of the arm portion to prevent the ball from escaping when the ball is thrown by the user from inside the arm portion; and a securing portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user. (Disclosure has been provided of a securing portion being within a scope of being shaped to travel around a reverse side of the user, reverse with respect to side wearing the arm portion, to secure the arm portion to the user). (Disclosure has been provided of a securing portion being within a scope of being a securing portion, to secure the arm portion to the user, that comprises a portion that travels around a reverse side of the user, reverse with respect to side wearing the arm portion). Preferably the securing portion travels around a torso of the user, lower than where a reverse side arm of the user is attached to the torso. (Disclosure has been provided within a scope of wherein the securing portion is shaped to travel around a reverse side of the user, lower than where a reverse side arm of the user is attached to the torso). (Disclosure has been provided within a scope of wherein the securing portion comprises a portion that travels around a reverse side of the user, lower than where a reverse side arm of the user is attached to the torso.). Preferably the securing portion also travels around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso. (Disclosure has been provided within a scope of wherein the securing portion is shaped to also travel around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). (Disclosure has been provided within a scope of wherein the securing portion also comprises a portion that travels around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso). Preferably a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, removably attachable to the securing portion, the arm portion attachment comprising the hand end of the arm portion. (Preferably the removably attachable arm portion attachment spans at least half length of the arm portion.) Preferably the arm portion is increasably and decreasably adjustable in length. (It is feasible that a portion of length of the arm portion may be removable / addable, to change length of the arm portion). Disclosure has been provided relating to possibility that the arm portion is removable and replaceable, there being provided another said arm portion(s), of a differing length, that can replace it. Disclosure has been provided relating to possibility that the securing portion is removable, there being provided another said securing portion, of a differing size, that can replace it. Preferably tightness around the user of the securing portion is increasably and decreasably adjustable. Disclosure has been provided relating to possibility that a portion or a whole of an elbow of the throwing arm of the user is visible whilst the arm portion is worn. Preferably the securing portion is substantially symmetrical designed, from back-to-front, in order to be substantially as comfortable both for right-handed throwing and left-handed throwing. Preferably securing portion comprises an armpit aperture. (See feature 30 in Fig 2, for example). Preferably at least a portion of the arm portion is expandable with reference to tightness around a top half of the arm of the user. (See feature 28 in Fig 5, for example, and textual disclosure relating to this and other possibilities for how to achieve a similar effect). (Disclosure has been provided, broadly speaking, within a scope of wherein a portion or a whole of the arm portion is increasable in size (around the arm). Thus such terminology may be used). (Disclosure has been provided within a scope of wherein a portion or a whole of the arm portion is provided by way of a removably attachable arm portion attachment, the arm portion attachment comprising the hand end of the arm portion). (There has been provided disclosure in the present application of wherein there is provided more than one removably attachable arm portion attachment, of differing sizes, (each said removably attachable arm portion attachment being interchangeably attachable to the securing portion and thus interchangeably usable). There has also been provided disclosure in the present application of wherein there is provided more than one said securing portion, of differing sizes, (to which the arm portion attachment is removably attachable), (each said securing portion being interchangeably usable with the arm portion attachment). This opens up the possibility, of course of multiple different removably attachable arm portion attachments being usable with multiple different securing portions. It has been made clear in the present application how these different size combinations can be important / beneficial, for users of various different sizes / shapes). Disclosure has been provided in the present application relating to how, preferably, a portion or a whole of the elbow of the user is visible whilst the arm portion is worn. It has been explain how, analysing of (a portion or a whole of) the elbow, (eg position / bend during the act of throwing, for example), can be useful. It could be beneficial for analysing of throwing technique reasons. Analysing (and improving) throwing technique can be good for improving the throwing action of the user. Aside from the benefits in terms of better throwing, this can be important for rehabilitation purposes, (eg to change / avoid bad throwing technique(s) that may increase chances of further injury and / or prevent full or as-rapid-as-possible healing / rehab from injury). (Various disclosure has been provided, in the present application, with regard to an arm portion, for being worn by a throwing arm of the user). (Various disclosure has been provided in the present application within a scope of wherein the wearable apparatus comprises a connecting arrangement, to facilitate the / an arm portion attachment being releasably connectable to the / a securing portion. (Various embodiments have been disclosed)). (Disclosure has been provided within a scope of wherein a portion or whole of the / an arm portion is removably attachable to the / a securing portion). (Disclosure has been provided within a scope of wherein the wearable apparatus comprises a separate connector(s), to connect the / a removably attachable arm portion attachment to the / a securing portion). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, and also travels around the side wearing the arm portion). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and also travels around the side wearing the arm portion). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso of the user). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, higher than where a reverse side arm of the user is attached to the torso). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, higher than where a reverse side arm of the user is attached to the torso, and also travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso). (Embodiments have been disclosed within a scope of wherein the securing portion travels around the reverse side of the user, and also travels around the side wearing the arm portion, higher than where the arm wearing the arm portion is attached to the torso of the user). (What is shown in Fig 2 and Fig 9 perhaps shows most clearly an example of a securing portion that travels around the side wearing the arm portion, higher than where the arm wearing the arm portion is attached to the torso of the user). (A significant array of different options and / or embodiments are possible. Thus this is made clear). Most preferably, the securing portion travels around the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso, and also travels around the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso of the user. (The user may also be referred to as the ‘wearer’). (Various examples are shown and / or disclosed in the present application of a securing portion within a scope of wherein the securing portion travels over a shoulder of the user. (Various examples are shown and / or disclosed in the present application of a securing portion within a scope of wherein the securing portion travels over a throwing arm shoulder of the user). (Various examples are shown and / or disclosed in the present application of a securing portion within a scope of wherein the securing portion travels over a reverse side shoulder of the user). (Disclosure is provided of wherein the securing portion travels over both shoulders of the user). (Broad terms such as 'goes over’ may be used, rather than 'travels over’). (Note: In the present application, the term 'above’ [the / an arm of the user] is sometimes used. If so desired, the term 'higher than where the arm is attached to the torso’ (or the like), may be used. This statement makes clear that such terminology, (especially in light of this statement), is deemed supported). (Note: Whilst the example(s) of a securing portion in the Figures show an embodiment that is fairly ‘solid’ in nature, as has been stated in the present application, a wide array of embodiments are possible, not limited to the examples shown. For example, an embodiment(s) could be provided that is more 'harness’-like, for example, in structure. Various options and / or embodiments are possible). Fig 9 shows a side view of a person using the wearable apparatus, after an example ball 15 has been thrown / released by the user and as the example ball has impacted the example hand end 14 of the example arm portion 12. As can be seen in the example of Fig 9, the example portion 26 does not quite go up to the armpit of the user. (Preferably it is approximately two to three inches short of the armpit). This can be important for comfort of the user. It could negatively impact the thrower if portion 26 extends all the way to the armpit. (Thus, broadly speaking, it is an example within a scope of where the wearable apparatus / arm portion is configured / designed / shaped to not go up to the armpit of the user). It could cause significant discomfort by engaging that area of the user. (This could affect the user’s throwing action). In the example, the ball 15 impacting the hand end creates a significant ‘pulling’ force on the arm portion. However, example connector 20a, (provided simply by way of example only), can be seen doing its job. (The example securing portion is shown doing its job). (An example shirt 51 is shown being worn by the user, in the example. (This can generally simply be described as an item of clothing. (An item of clothing, (more like a ‘hoodie’), is being worn by the user in Fig 2)). (An example back portion 24 can be seen, from the angle / view shown). (It should be noted, ‘netting’ / ’mesh’ is not denoted in Fig 9. (This is simply to aid clarity). However, preferably this is the case, with the embodiment preferably being the same as shown in Fig 2, (which denotes this). However, as has been stated, various options and / or embodiments are possible). The user’s throwing arm is denoted in basic fashion in the example arm portion, (denoted with dashed lines). At such a moment after release, the user’s finders may even be ‘extended’, after having thrown the ball. Fig 9 is a good demonstration of just how effective (and beneficial) the example wearable apparatus can be. (In the example, the ball could have been thrown extremely hard, for example). What is shown in Figs 5 and 6, (and Fig 8), can be called a 'securing part’. (As made clear, embodiments can be provided where this part alone provides ( / is) the whole securing portion. In other embodiments, there could be a 'separate’ connector(s), (as has been made clear), (and example connector 20b1 is a very good example of this)). (As alluded to, it may be that such a (or any) securing part travels around a torso of the user, at the reverse side of the user, lower than where a reverse side arm of the user is attached to the torso. (However, it should be stated, embodiments have been disclosed relating to wherein a ‘separate’ connector ‘bridges the gap’, in use)). (As alluded to, it may be that such a (or any) securing part travels around both sides of (a torso of) the user, lower than where a reverse side arm of the user is attached to the torso. (However, it should be stated, embodiments have been disclosed relating to wherein a ‘separate’ connector 'bridges the gap’, in use), and this is not limited to 'bridging the gap’ where the gap is at a reverse side of the user- the (or any) gap(s) could be anywhere, not limited to being around the reverse side of the user- for example, the securing part could go around both sides of the user (eg lower than where each arm is attached to the torso, for example), but could then not meet or overlap somewhere else around the user, (eg at the front (and / or back, for example)). A ‘separate’ connector(s) could then bridge the gap, for example)). The example, (provided by way of example only), is within a scope of being a securing part that travels around the torso of the user at the side wearing the arm portion, lower than where the arm wearing the arm portion is attached to the torso of the user. The example securing portion, (eg as shown in Fig 2, for example), (pr...
