It is no secret that one of the reasons many of us get leg lengthening is to fair better with the opposite sex. Now, I don't exactly do poorly with the ladies, but I know that I would do better if I was taller. I've heard plenty of men and women cite the evolutionary argument--that women are "programmed" to seek taller men, as they supposedly are better protectors. However, height doesn't seem to play more than a minor role in one's combat ability, with most boxing experts saying that smaller guys tend to punch with just as much force as larger dudes, as smaller guys punch with more speed. Plus, it is no secret that being short and strong are not mutually exclusive; lamar Gant, Ed Coen, and Franco Columbu all sported 600+ lbs deadlifts at heights of 5'6 or less (Gant was barely 5'2). If women were concerned with ability to protect, than height would be less important than muscular strength, but most research has shown height to be as of more important.
I've also heard the argument that tall men are preferred because one can generate more force punching down rather than punching up (as tall men can punch down to strike their smaller opponents). But, this argument still seems weak at best, as short men can easily strike the solarplexes, lower abdomen, or even the genitals of a tall opponent by striking downward, which would arguably give short men an advantage in fighting.
So, what do you think? Why do women prefer taller men?
