Maybe the olympic athletes that are pushing their bodies to achieve the limits of human capability, yes. I think it's obvious why some (not "ALL") of them die young.
You're not going to die of a heart condition if you hit the gym 3 times a week.
Also nobody says "don't eat food" other than thinspo instagram pages. You should eat food, if you don't eat food you die.
Olympic athletes typically live several years longer than regular people.
