What do you look for in a mate?

An economist has the answer:

...for every 10% increase in a man's Body Mass Index, his salary must increase by 2% in order to [compensate women]. However, women who weigh more by two BMI units compensate [men] with a year of extra education, rather than money.

In other words, women have to be compensated with income for marrying a heavier man; while men must be compensated with education for marrying a heavier woman. HT: Larry
