Guess they'll have to start taking lessons from professional athletes who've had to figure out how to deal with not being able to "continue playing the game" and still be happy.
Speaking of which, why not sideline athletes which are exceedingly successful and leave some room for others? Nobody needs their 6th NBA championship or 10th Grand Slam title or 7th Formula 1 championship while their competitors, similarly talented and hard working, can spend entire careers not winning anything. Heck, it might even be better for the fans!
