Length of life and level of health and wellness are related to PNI (psychoneuroimmunology) function. Yes at times, unexplained healings do occur. But in general, if you get sick and if you get well, your body heals itself. It has been set up to prevent illness where possible and to heal illnesses where possible. Estimates are that 85 percent of illnesses are within your immune systems’ reach for healing. Albert Schweitzer, MD, put it this way: “Each patient carries his own doctor inside him--we are at our best when we give the doctor who resides within a chance to go to work.” Studies are showing how you can give the doctor within you a chance to go to work.” I agree. How do you do that? In my brain’s opinion, you do it by creating and living a Longevity Lifestyle—it Matters. That’s the reason I wrote The Longevity Lifestyle Matters Program, with Sharlet M. Briggs, PhD, and Steve Horton, MPH. Embracing a Longevity Lifestyle has certainly made a positive difference in my life!
