The reason Women don't compete in men's sports is because of respect and there would be a lot more scandals. Also, the society we live in believes men and women aren't equal. Besides that, I really don't know why. The reason women cant run faster than men is because of the bone structure and just physically men are more strong but that doesn't mean men are better. :) plus the reason m-f are more active in sports are because women are more brave than men
