My best guess would be that we get more concious of those areas because that's where we cut. Even if we aren't specifically thinking of cutting there, I think the areas that we generally do cut may become linked in our brains to the impulse (or even thoughts that make us start to have that impulse) in or brains to cut. Does that make any sense at all? lol

It is just a guess, though. I've never read anything on it. Although I think I have experienced it. Just never thought about it much before.
