A new study finds that when it comes to sex, it's all about keeping up with the Joneses. The research examined the connection between happiness and how often people have sex. It found, as other studies have, that the more often people have sex, the happier they are. It also found that people who believed they were having more sex than their peers were happier, and vice versa. Ryan Warner speaks with Tim Wadsworth, who's the study’s lead author and an associate professor of sociology at the University of Colorado Boulder.
