A 2013 paper written by Nick Drydakis, professor at the School of Economics, Finance, and Law at Anglia Ruskin University (UK), suggested a link between more frequent sex and higher income rates. The initial hypothesis of this study was that the medical, psychological, and physical positive effects of sexual activity (good health, endurance, mental well-being, etc.) could influence wage factors in working adults.
The hypothesis was proven to be correct – according to the results of this study, employees who are having sex more than four times per week reported receiving statistically significantly higher wages than those who reported having less sex.
