Differences between women and men.

[Excited Penguin]

No, I still think social is better. I can't think of any environmental disparities between the sexes, can you?

I'm talking strictly about humans here, and I think the question in the OP was directed at that as well. We're not talking about genders at a more general animal level.

Do males and females spend their days doing the same things? Our lives are pretty different from each other in general.

That's not what I was saying. It's just that I think social would be a better word to describe it than environmental.
