Do you think the exclusive focus helps their performance at their sport?
Do you think competition selects for people with mental health problems, or causes mental health problems?
Is there a noticeable difference between athletes who burn out in a few years vs. the ones who have long careers?
Some 30 hours a week in the off-season. Additionally, many have off-season jobs to make ends meet. Pro sports isn't all what it's cracked up to be. Not all of them play on TV.

Genetic ability first, preparation second. If you are an extremist, you might get preparation to exceed your genetic lottery ticket. But I've only seen that happen once.
I train hundreds of professional athletes. The majority of them do not have rich lives outside of their training. Most of them have very unbalanced lives that center around their sport, training, and everything to do with it. Most relationships fail inside pro sports for several obvious reasons.
Most have some form of mental health issues.
We watch them on TV and we expect greatness, but as long as it is not us paying the cost to get there, we don't mind.
