People who are bad at drawing can't become painters, people who are bad at playing musical instruments can't become musicians, and people who are bad at sports can't become athletes. Strangely enough, even people who are clumsy with their hands can become surgeons, and what is often overlooked is that, unlike art and sports, surgeons directly affect people's lives and bodies. [Solution] Just like abacus classes, piano classes, English classes, calligraphy classes, and swimming classes, if surgical classes were established and children practiced surgical procedures using cadavers such as pigs from a young age, they would already be surgical masters by the time they are around 20 years old, the age when ordinary medical students first pick up a scalpel.
