ATLANTA, Georgia (CNN) – Can you tell whether someone’s gay just by the way he or she walks?
Take Richard Lippa, a professor of psychology at California State University at Fullerton. His studies show that gay people are twice as likely to be left-handed, drive yellow BMW’s, and have the last name Savitsky.
He also collects photos of hair whorls – those circular swirls you see atop a man’s head. He says about 10 percent of the general population have whorls that rotate counter-clockwise, but about 20 percent of gay men have counter-clockwise whorls.
