[taxer]

I wonder if its down to being left or right handed, as (im guessing?) right handed people will use / make more muscle on that side of the chest, perhaps stopping the growth as much, similarly left handed would have smaller left breast???

tell me i'm mad.............

Interesting theory - in my case, I'm right handed and my right breast is the bigger one so MAYBE there is something to that.  I'm curious to know iif a left handed person has the left breast bigger than the right.
