Left-handed people are increasing.
Right now, there are more left-handed people than ever before. 100-years ago, only 3% of us were lefties. Today, it's at least 11%. University College London thinks the increase is because parents aren’t forcing their kids to use their right hand anymore. And there are more lefties to come. With so many women waiting until they're older to have kids, more left-handed babies are expected to be born. Because older moms are more likely to deliver kids who favor their left side.
