While I was switching channels this week I saw part of a segment on the Doctors (at least I think it was).
One of the things they were showing were brain images of a straight male, a gay male and a female. They were showing that the gay male had almost the exact same brain image as the female and far different than the straight male.
It was over, but the 15 second comment was interesting. Then they changed subjects. I've viewed similar studies over they years. Basically I think they were making the case that gays have different wiring. I would susspect that CDs have similar results if studdied.
