I can't help but think that the (mostly women) who think men and women have very similar physical aptitudes of strength and speed missed some formative experiences that used to be pretty common- Like roughhousing, climbing trees or racing against boys in mixed sex groups.

In movies and on television, women can often hold their own against men. When in reality- an incredibly physically fit women could be beaten soundly by an overweight middle aged guy. Try play wrestling with a dude before you tell me men and women shouldn't be divided in sport.

Speaking of which- play wrestling with @primalpoly he was being as gentle as possible with me, whereas the only way I could gain a physical advantage was with my relatively lower center of gravity, by launching myself at his torso.
We are more careful now...
