One inch equals $30,000 in online dating world

A Duke University study analyzed data from 22,000 online daters and found that "women put a premium on income and height when deciding which men to contact."

For example, the study showed a 5-foot-9-inch man needs to make $30,000 more than a 5-foot-10-inch one to be as successful in the dating pool.
