We can stop searching for the fountain of youth. Scotland's oldest woman, Jessie Gallan, has the secret to living forever (or at least until 109, her current age).
"My secret to a long life has been staying away from men. They're just more trouble than they're worth," Gallan, who has never married, tells the Daily Mail. Sage advice. In addition to preserving one's youthfulness by avoiding troublesome menfolk, Gallan recommends a bowl of porridge every morning and plenty of exercise — which, frankly, sounds like the harder advice to stick to.
