"Women who had sex at least four times a week were scored as looking up to 10 years younger than their actual age."

Science worth reporting: "Women who had sex at least four times a week were scored as looking up to 10 years younger than their actual age."

There may be a cause-effect problem there. Even if it is completely valid, it could be because men want to have sex more often with younger-looking women, not because having sex makes one look younger.

But don't tell women about the causality question. Just give 'em the ... er ... hard facts.
