A new study says that maintaining an active sex life is good for the health of your brain.

Older guys who get laid regularly have better “brain health” and are less likely to lose memory, according to the Coventry University study.

Men ages 50 to 89 with active sex lives scored 23 percent higher on cognitive word tests and 3 percent higher on numbers puzzles, according to the researchers, who quizzed 6,800 people across England.

Women who had more sex scored better on the word test but not the numbers test.

The improvement for men on the numbers test was pretty small (only 3%) so that result is questionable. It’s safe to say that more sex is good for the brains of both men and women (though correlation does not equal causation). So, if you want to protect your brain, maintain your ability to recall lists of words, and boost your immune system, I recommend that you have frequent sex.
