here is something i found somewhere online that i copied a while ago.

Simple. Its called testosterone. Its kind of amazing how much stronger men are. My partner used to teach a self defense course, and its really a disservice to women for all these crazy shows and books to confuse them into thinking that they have any sort of a chance against a healthy male. Even if a woman is well trained around 60 percent of the men her age are capable of laying her flat. For an average woman its much, much worse.
