Quite a lot of what you fancy, apparently, does you good, scientists have claimed.

Couples who have sex at least three times a week look more than 10 years younger than the average adult who makes love twice a week, says consultant neuro-psychologist Dr David Weeks, who has made a 10-year study of the subject.

"Pleasure derived from sex is a crucial factor in preserving youth. It makes us happy and produces chemicals telling us so," he claims.

"I would say that famous people with youthful good looks, such as Goldie Hawn, Helen Mirren and Joan Collins, all enjoy very active and healthy sex lives."
