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.
