Arnold's Comment on Crying
In episode 3 of the third series, Arnold comments that boys cry as much as girls until they're about 10, but then they stop because society tells them it's not acceptable. This is kind of an interesting topic b/c right now society's all over the idea of men opening up emotionally and dropping the masculine pretense or whatever. But I don't think socialization is the only reason men cry less after they hit puberty age. Testosterone and tears create almost a negative feedback loop. Just ask any trans guy; they tend to agree they don't cry as much after they start hormone therapy as before. And seeing a woman (or anyone) cry has been demonstrated to lower men's blood testosterone levels. It's like a built-in anti-rape precaution, maybe.
Josh and Arnold are clearly not the most testosterone-y guys, so they'd probably have a different perspective on emotional expression than your average man. But I think there is a physiological component to average male and female behavior. Don't get me wrong; men and women behave differently across different societies and time periods, and there's a lot of variation between individuals of either sex. I just wonder how far society can push the concept that gender is entirely a construct before that proves to just not be quite true. Discuss?
