Stop with the negativity, America. Singles are sick of it. Indeed, 51% of Match members have broken up with a pessimist. They want a partner who smiles, is enthusiastic and thinks of the future, not the past. And for good reason. Negativity stresses the body and the mind. We’re naturally drawn to positive people because when they smile, we automatically smile too—and smiling triggers facial muscles that trigger the brain’s pleasure centers to make you feel good. Sure; there’s much to cry about. But if you want to attract the right partner and fall in love, be happy. It’s one of nature’s secrets to romance.
