Today is St. Patrick’s Day, a day when college-aged Americans celebrate Irish culture and its incredible impact on the U.S. by day-drinking, wearing green T-shirts that were made in Cambodia, and fighting each other. This year, it’s also the day Match.com decided to release some puzzling statistics on red-haired women’s sex lives. It’s no secret that there are a lot of Irish people with red hair. And now, we have a whole bunch of numbers that seem to confirm the old stereotype that red-haired women are more “sexually liberated,” in Match.com’s words, than women with other hair colors.
