Re: why cant kobe play till he's 50?
As always, these questions are posed by people who have never been anywhere close to 50 years of age.
It takes far more preparation than it does for a player 20 years younger. Couple that with the fact that it takes far more recovery time from workouts and games and you start to see problem. Physiologically, muscle tissue respomds far differently as you age. And that doesn't even address the psychological difficulty of wanting to prepare and play year after year after year.
