Two points. One, we are living in the age when wearing shorts that are splits is akin to running around naked, and will get you beat up in places--people somehow got real uptight about these things, and we are in a real uptight time period in general. Two, maybe us older dudes are just more comfortable about nudity and our lumpy bodies in general--I mean, like I CARE what some 22 year old kid thinks of me? On the flipside, that 22 year old is still pretty damn close to the age when everything he does, think, or says is judged by his kiddie peers, and he better err on the safe side and cover up or else. But, I do agree about the thing about "personal space"--I don't want some dude's sweat on me, so watch where you're swinging that thing...lol.
