When I say young, I mean the late teen/early 20's physical look. I am now 23, and some people didn't want to cam w/ me because they thought I was underage. LOL. I guess that bolds well when I am 50. Of course, some people at 18 already look like grown adults, or worse. By contrast, there are people over 30 who look fantastic and like in their 20's. 1) At what age does that look start to go, on avg? 2) Is it genetic, or related to diet and other factors? 3) Which gender tends to age more between 20-30?
