true age difference is similar tho to different weights and different genders. Also whether someone is disabled or not, so I am ok with them having the paralympics. And once adults, I know sometimes they have sports for only old people, like you need to be a certain age. There's a 50 and over basketball league near me, I can't join it but that's fine I don't need to go in there and dunk over grampa to feel like a real man.
