A new study published by the Institute for Study of Labor in Germany suggests that people who have more sex tended to earn more money.

Drydakis and his colleagues surveyed around 7,500 people in Greece, asking them about their age, education, religion, sexual orientation, what did they do for living, amount of money they made and how many times they had sex in a week. The researchers also found that the link between sex and earnings was the strongest among people between 26 and 50 years of age.
The researchers said that while having more sex was linked with more money, even the reverse was true. “Higher wages may encourage some to adopt more sexually active lives. For instance, higher wages may increase the value and attractiveness of a person on the dating market; higher wages may increase purchase of gifts that are thanked for via sex”, the researchers wrote in their report.
