In her fascinating new book, "Do Gentlemen Really Prefer Blondes?" American science journalist Jena Pincott collates scores of academic studies, to say that wrinkles do not make a woman appear less attractive to the opposite sex.
In scientific tests, men were asked who they saw as a potential partner for a short-term relationship. As it turned out, they gave low attractiveness ratings to older-looking faces.
That, according to the researchers, is because men are biased towards youthful-looking women with childbearing years ahead, which prompts them to marry younger women.
But, ironically, if a man's mother was over 30 when he was born, he tended to be more tolerant of ageing in women's faces in the context of a long-term relationship.
It was only the mother's age at his birth, not the father's, which influenced a man's acceptance of older looking women's faces.
According to the researchers, such a tendency owes itself to sexual inprinting, the tendency for a person to seek a mate who resembles his or her opposite-sex parent.
