Go Back in Time

Dr. Oz and Dr. Michael Roizen are back with more from their book YOU: Staying Young. Dr. Oz has said it's within your power to live to 100—now find out how to do it!

One of the centerpieces of the "You: Staying Young" program is the 14-Day Plan. Dr. Oz says he and Dr. Roizen chose 14 days because that's how long it takes for the brain to reprogram itself with new activities. "In two weeks, chemically, you can actually shift how the brain deals with anything going on outside of you," he says. "At three months we can actually begin to measure life expectancy changes. And in three years, you've got 90 percent of all the benefit you're going to get from the new life."

There is only person who can make this changeyou. "People come to me all the time in the office and say, 'Can you cure me?' I can only help," Dr. Oz says. "The only person who can really cure youthe only person who is the world's expert on your bodyis you."
