It's the study that you can take to the bedroom.
Researchers now say that for a happy life, you should have sex once per week.
According to the study published in Social Psychological and Personality Science, couples having sex less than once a week report being less happy and couples having sex more than once a week do not report being any happier.
And if you're single, the study says there is no consistent association between how often you have sex and how happy you are. Sorry, singles!
Val completely disagreed with the study and then surprised us all with her own "Happiness Plan." Check it out in the video.
