Why do women care so much about their looks?

it`s funny u ask about this.. i went to the zoo two weeks ago and i realize we are, in the animal kindom, the only one where the female is the one making so much effort to conquer the male... think about it, should be in the other way arroud... they are the ones who has to provide... we help, but that`s it... and we have to wax our legs and bikini areas!!?? i don`t think so!!!!!!!
