My point is that I'm not convinced that the kids are getting less exercise than previous generations. If I had to guess, I would guess they are getting more. Are they watching more TV? You bet. What they don't spend time on so much anymore are hobbies. Sports are the main hobbies of a lot of these kids.
Not for every kid, to be sure. But for a helluva lot of them.
