People without sex die earlier than others — research data. If you don't make love at least once a month, you're at risk.

American scientists conducted a 15-year study involving 5,000 people and proved that sex less than 12 times a year significantly shortens life. Such people are more likely to be overweight, smoke, become depressed, and suffer from high blood pressure or diabetes. This is especially true for those who tend to be overweight.
