A tilt of the head can make both men and women look more attractive, according to a new study. ... The results may hark back to the differences in male and female height, the researchers report in the journal Evolutionary Psychology. Men are typically taller than women, so they're used to seeing female faces from above—an effect mimicked by a forward head tilt. Women, on the other hand, usually look up at men's faces, so the head-back tilt may appear more masculine. Previous studies have shown that ladies dig men with relatively short upper faces, though fertility can affect what women find sexy.
