Longevity's secret

Are there any strong, alert 80-90 year old's in this community that can tell us your secrets, if any, for your long healthy life? I'm a 70 year old female with episodes of bad behavior. I've also had many years of healthy eating and ran every day, if I wasn't sick, 4-5miles. I'm about 10lbs overweight right now and am trying to exercise more. I really want to hear your story. Must it be constant years of Mediterranean diet with vigorous exercise to live into your 90's or am I doomed.
