If you want to see the glorious difference between men and women (and have everyone keep their clothes on, mostly), you need look no further than a gymnastics competition.  Myself, I am not particularly a fan; I haven’t even watched Olympic competition for almost a decade.  But I know, for instance, that women do not perform on the pommel horse, parallel bars or rings.  And after watching Olympian Shawn Johnson attempt it, I know why.  The same reason I don’t.  It’s impossible.  The upper body strength is just not there.

The men don’t perform on the uneven bars or balance beam.  And I know why.  The same reason I can’t watch them try.  Physiology.  Let’s just call it physiology.
