Reverse Your Aging Process

Dr. Oz has something to say that could change your life. "If you are in reasonable health, there is absolutely no reason why you don't have a fighting chance to get to age 100."

Despite what you might have been led to believe, Dr. Oz says that living to 100 isn't about avoiding diseases like cancer, heart disease or stroke. He says if we could rid the world of those common killers, it would add less than a decade to life expectancy. "Aging's not about avoiding disease," he says. "It's about living with vitality."

In their book YOU: Staying Young, Dr. Oz and Dr. Michael Roizen get to the bottom of the true nature of aging. Some people think living to old age is a forgone conclusionthat it's all in your genes. In truth, Dr. Oz says, 70 percent of how you age comes from how you live. "We spent a ton of time looking into where the true fountain of youth isand you know where it is? It's right inside of you. It's in your cells, it's in your 'kitchens.'"
