There are some gender differences that are just set in stone, aren't there? Oh, sure, we can debate the math/reading difference, and we're still learning a lot about it, so who really knows, anyway? But surely, some of the aptitudes and abilities we think of as gender-based really are, right?

Well, I remember hearing a story a few years ago about a fellow somewhere in Asia who began lactating and breast fed his kids after his wife died giving birth, a story that gave me a huge kick. So, I was delighted to stumble upon this story from last February in Scientific American about this. The conclusion: males can, indeed, lactate.

Maybe this will get the ball rolling on people suggesting that more men can be stay-at-home dads to infants? Oh, sure, call me a dreamer. Okay, I'll settle for a little more critical thought about "hardwiring". Still too much? Tough crowd!

Hey, Barbie, gender differences are confusing! Let's go do some math!
