You've probably heard that people find face-symmetry attractive, but researchers report that the "sexiness" of face symmetry can be seen across cultures and even in "non-human primates" (again with the monkeys judging attractiveness!). Researchers also looked at sexual dimorphism — or how masculine/feminine a face appears — and how it fits into general attractiveness and explain that the reason people/primates find symmetry and sexual dimorphism attractive is because they may be an indicators of disease resistance. (Wonder when Vogue is going to start marketing "disease immunity" as a Hot New Beauty Trend! Probably once they run out of ways to market $50 sunscreen.) Either way, we all can feel bad about our lack of face symmetry, because how the hell are you supposed to know how symmetrical you are?[UPI]
