Actually, I just thought of something. When you see a guy from behind with no hair or a very short buzzcut - do you think old or young? Or do you wait until you see his face?
When I was growing up bald men were old, period. Now very short hair or bald heads are all the rage, over here at least, so it's just as likely that a bald guy is his twenties as in his sixties. Just something to ponder. Times do change.
