I was the person who commented on 'random older person' and by that, I meant it was usually someone older than about 65 who clearly didn't care what other people thought about them. It's not that they were flaunting themselves, but more that they just think about it. I do think it's probably partly due to maturity, but probably also due to comfort with being there. I mean think about it, how many 65+ year-olds do we know who workout regularly at a gym? Maybe most of those who do, have been doing so all their lives and therefore, the locker room is a very comfy place for them? Who knows, I'm just throwing out ideas here...

I will say that I am much more comfortable being naked in a locker room now than I was when I was a teen. I don't think it's body image as much as it's 'social norms'. When I was a teen, all the girls were modest. None of us walked around naked. It may have been different had I been on a swim team in HS, I suspect. Now I find that if everyone else is naked, I don't care if I am too. If everyone else is doing the 'towel dance', then I try to be a bit more modest myself. Social pressure. I like it when other people are comfortable around me...always have. I will go out of my way to ensure that I'm not making someone else uncomfortable, but I'm weird like that.
