yes, men and women differ physically. Men are going to win in terms of strength and size, but not all sports are about purely strength and size.

And men and women *think* differently, too. I think that's been pretty well documented. But just because your approach to problem-solving is different, doesn't mean you're wrong. So the parallels are still there -- men and women have different strengths, both mentally and physically. Perhaps it's just that the physical differences are more obvious.
