Being larger is a disadvantage, I have to carry more weight. And women are definitely smarter, which makes more sense in a caveman world than a civilized one because women did all the intricate stuff and raised kids while men did mostly fighting and hunting and hard labor. For that reason the only thing men are smarter in is simple spatial awareness, ie where a football is going to land. Despite this men are expected to do all mental labor in the modern world, which is why they appear to be smarter when in fact they're far dumber.
