The Science of Gaydar

Does gaydar exist? I think so because I have seen mine at work in a few cases. Though is there a science to it?

Until now the scientists and social researchers have been trying to figure out how gay men can determine how is and isn't- or how anyone can determine someone's sexuality. New, interesting research has been conducted on that very premise.

Researcher's have studied the swirl of men's hair, the length of ringfingers among other physical traits and say these can be factors that determine someones sexual orientation. It's not always accurate as their are more nuanced factors ay work with gaydar. Still, a very interesting study with interesting results.
