“It turns out, women really care about men’s height. I’m 5’9”, if I wanted to be as attractive as somebody who’s 5’10”, right, another inch? I would have to make about $35-40,000 more a year. That’s a lot of money for one inch. At the same time, it turns out that men care a lot about women’s BMI’s. In fact, they want women to be slightly anorexic, at like 18-1/2. And you look at women’s attractiveness, it goes really up at low BMI and really drops below that.” -Dan Ariely, Professor of Behavioral Economics, Duke University, from Why Online Dating Is So Unsatisfying.
