As if to demonstrate that every silver lining has a cloud, researchers in the US have shown that older men who enjoy frequent s*x raise their chances of developing heart problems.
But the same was not seen for older women, who appeared to suffer no ill-effects from a robust sex life, and tended to have lower blood pressure when they found sex highly enjoyable.
Men in their late 50s to mid-80s who indulged in sexual activity once a week or more had twice the risk of heart attack, stroke or other cardiovascular conditions over the next five years, compared with men who went without, the researchers found.
To make matters worse, the men who enjoyed sex the most were more likely to suffer heart conditions than those who were not so bothered.
The findings emerge from one of the first large scale studies into the impact of sex on the health of older people. More than 2,200 people who enrolled in the US National Social Life, Health and Ageing project took part in the study at Michigan State University.
