60 Minutes had an interesting piece on the origins of homosexuality last night. Basically, they looked at the origins of sexual orientation and found, you guessed it, it’s complicated. Still, they did come up with some interesting tidbits:

"The more older brothers a man has, the greater that man's chance of being gay," says Bailey.

Asked if that's true, Bailey says, "That is absolutely true."

If this comes as a shock to you, you’re not alone. But it turns out, it’s one of the most solid findings in this field, demonstrated in study after study.

And that’s before they get to the right-handed, left-handed stuff. Still, it’s an interesting piece (you can read online). We just wonder what they were getting at when they did the part of 8 year-old Adam who showed the camera his Bratz Baby doll because we have one too. Does that prove we’re gay, too? No, it was probably the overly molested Ken doll we've had since we were five.
