Dr. Oz's Anti-Aging Checklist

In addition to lack of sleep, Dr. Oz says we're deprived of something else in the bedroom— sex. "The average American has sex 58 times a year—so, once a week. If you double that, you reduce your 'real age' by almost three years."

Dr. Oz says sex creates an increase in chemicals that keep us young. "When you have loving conjugal love with someone and you actually have that passionate moment, you not only exchange bodily chemicals, but you make chemicals within you," he says. "So women get oxytocin increases, which give you that loving bond that you want with the world around you and people around you. Men have an increase in testosterone. Testosterone is what puts the moan in hormone. It sort of gets you going."
