For a very long time it has been thought that complex physical skills cannot be developed once past a certain age or without the requisite talent. This belief still restricts people in the choice of their physical practice and it would be a great relief for me personally if the fact that this information is wrong reached as many people as possible.
Injury can be a devastating event that puts the end to a sports career or simply leaves you unmotivated to do any kind of physical practice. But depending on how you look at it, it can also be a door into self discovery and a very valuable learning experience. I truly believe it is important to know a bit about the subject even if you are only an amateur. Knowledge is power and possessing at least some sort of correlated information leads to much wiser decisions and better assessments of the situations.
