Many set a goal of living longer, but medical breakthroughs now indicate that we are at the controls as we set our sights on living younger. In his new PBS special, Dr. Michael Roizen provides an easy plan of action to fight life’s “major agers” — those internal and external forces that cause the most wear and tear on the body.

Dr. Roizen shares the latest findings about the biological processes that control how and why we age the way we do, then reveals an action plan for staying young based on cutting-edge science. Tools and tips designed to help viewers manage stress, safeguard against toxins, stay sharp and live long are offered as ways to slow the aging process.

With the help of male and female specimens from the “Bodies” scientific exhibit, Dr. Roizen visually identifies and explains the body’s organs, arteries and nerves affecting the aging process, offering gender-specific guidance on such factors as hormone therapy and nitric oxide.

Dr. Roizen explains the genes that predispose people to diabetes and other diseases, along with instruction for “turning off” negative genetic traits through a change in vitamins, diet and exercise.

You: Steps for Extending Your Warranty, based on Dr. Roizen’s #1 New York Times best-seller You: Staying Young, also offers information on ways to alleviate a major concern about growing older — reduced mental capabilities. In this taped presentation before a studio audience, he reveals the foods, supplements and mind games that build brain power.

Dr. Michael F. Roizen is a professor of anesthesiology and internal medicine and chair of the Division of Anesthesiology, Critical Care Medicine and Comprehensive Pain Management at the Cleveland Clinic. Previous best-sellers include You on a Diet and The RealAge Makeover, which also became PBS specials, and two other books, You: The Owner’s Manual and You: The Smart Patient.
