Good point, Twitch. I recently saw a documentary on the subject of male/female attraction. It presented that around the time a woman ovulates, she tends to be more attracted to males who project an aggressive, alpha-male personality. After ovulation attraction to this type of man diminishes for many women.
Of course I wasn't specifically referring to this sort of thing in the post--and I wasn't trying to project "Legends of the Fall" onto reality. It really is just that I have seen this type of disparity throughout my life, and that movie seemed to isolate it pretty well.
