Comment does the media cause biceps and boobs? hormones (Score 1) 765
Does "the media" cause young girls to associate boobs with women, and therefore cause the girls to later grow boobs, or is there perhaps a biological thing called hormones, which effect all manner of gender differences?
Of you look at people who take testerone or other steroids, you'll find that it has a very obvious effect on their behavior, by way of the hormone's effect on the brain. Over the course of millions of years, male brains evolved around their essential tasks of "go kill something and drag it home for dinner" along with "fight off the predator". See how muscle cars and football might stimulate something in the male brain which is now lacking in means to express the "kill something and drag it home" instinct? For these millions of years, females had a different role, to which their brains adapted. Neither is better or worse, our brains and other parts are different.
* obviously I'm speaking of the majority of men vs the majority of women. Exceptions exist - Chrisley probably wouldn't have survived and reproduced in the days of hunting wild boars to eat.
