What is the secret to Betty White’s longevity? Tue-28-Aug-12 09:50 Share this By Jay-Jay Feeney90 yr old actress Betty White is in fantastic shape for her age so she often gets asked the secret of her longevity. She says, "I have a two-story house and a very bad memory. I'm up and down those stairs all the time."Obviously, that's a joke. But her real reason is, "There's no spare time, so I'm active all the time. I think that forces you to stay well. To be 90 . . . and still be working, that's what I wouldn't have expected. I'm the luckiest broad on two feet."She says her diet isn’t the best though. "I should follow better eating health rules. But hot dogs and potato chips and French fries are my favorite foods."(Maybe THAT’S the secret to longevity? And if that’s the case, I’ve still got a long time left to live!)
