We're up against boobs. Lots of 'em. But not in the way that you'd think or would want, or that I should have started this paragraph with for the sake of confusion. It's just that I equate each woman with her physical parts, like all men, and there will likely be more women than men (or "pecs") in the future (legend has it women can actually BIRTH whole, tiny versions of themselves! Men, get on that).
Don't believe me? Let's ask Wikipedia's page on the human sex ratio, which features the below image.
Look at it -- girly pink staining everything like so much spilled bubblegum nail polish. They've already got most of the cool countries, plus Australia and some other random crap thrown in! WHY will the future be a clambake, and not the present sausagefest? Simple math, really, which, by the way, we used to be better at, but it turns out we aren't really; male teachers are just being mean to the girls in their classes. Go get 'em, fellas!
