If you're having trouble convincing your partner to have sex, tell her it's good for your heart. A new study found that men who have sex at least twice a week can cut their risk of a heart attack nearly in half. The study looked at the sexual habits of more than 1,000 men and found that sex has a protective effect on the heart. The study, conducted by the New England Research Institute in Massachusetts found that guys who have sex regularly are up to 45 percent less likely to develop heart disease than men who have sex once a month or less. Researchers who conducted the study say that physicians should ask men about their sexual activity when assessing their risk of a heart attack. Scientists believe that sex has positive physical and emotional impact on both men's bodies. Um, yeah, I'm pretty sure it does - thanks scientists. An earlier study by the National Cancer Institute found that men who ejaculated at least five times a week - either through sex or masturbation - significantly lowered their risk of prostate cancer. The New England Research Institute study only tested men, so it is not known if similar beneficial effects of sex will be found for women. One can only hope. photo credit: Zawezome
