Researchers from the U.K.’s Anglia Ruskin University surveyed 7,500 Greece residents to find out what effect, if any, sexual activity has on wages. They found “there is a monotonic relationship between the frequency of sexual activity and wage returns,” according to Nick Drydakis, the author of the study. Not only did more sexually active respondents earn higher wages, men who’ve hit pause on their sex lives reported earning 1.3 percent less than men who clocked any amount of time between the sheets with their partners.

So, what’s the deal? This study proves correlation, not causation—but it makes sense that sex, which can also make you a healthier and happier person, would help highlight your best characteristics to an employer, who may then reward a positive office go-getter with a wage that reflects his or her healthy attitude.

It’s possible the reverse also applies: If you make more moolah, you’re likely less stressed—and with less stress, you may find yourself more desirous of sexy time with your significant other. As Drydakis wrote in the study, “Physical and mental health, as well as personality characteristics, are important factors that affect wages. The patterns found in this study strengthen this reasoning.” Which way it works, we don’t really know.
