Fascinating, from my observations, female humans are self aware of themselves, much more than human males are.
Of course it goes without saying, there are always exceptions. My theory is, this behavior of increased self awareness, and complexes and perfectionism that female humans develop, is not something inherited, it's not instinct, but something developed over time, influenced by society.
If male humans would be regarded and treated as female humans are, as in, "the beautiful sex", the dominance in modeling, beauty products etc. I think male humans would have more awareness than female humans, wouldn't it be a interesting place, it's hard to imagine, male humans being the ones applying make-up, and being dominant in fashion, modeling and such, talking about their who knows what phenomena regarding their bodies.
I think if female humans were more strong than make humans, like female lions are, I think that would be happening today, and the world would be sooo much different.
