Your financial success now depends on how active your sex life is, at least according to Nick Drydakis, senior lecturer in economics at Anglia Ruskin University in Cambridge, England.

Drydakis found that those who have sex at least four times weekly made 5% more in wages than their less fortunate counterparts. Those who don't have any sex at all earned 3% less than those who were sexually active.

He writes in the paper titled "The Effect of Sexual Activity on Wages," published by the Institute for the Study of Labor in Bonn, Germany, that sex is a "barometer for health, quality of life, well-being and happiness."

The rationale behind the study is that more sexual activity may result in higher self-esteem, confidence, and overall happiness, which make employees more amiable, productive, and creative. Sex is important in how satisfied a person is in his/her personal life, and satisfaction in that area could affect work as well.

"People need to love and be loved (sexually and non-sexually) by others. In the absence of these elements, many people become susceptible to loneliness, social anxiety, and depression that could affect their working life," Drydakis said.

But then it's also important to note that it could work the other way around - that higher wages result in more sex because "they may increase the value and attractiveness of a person on the dating market," Drydakis says.
