“although our genes directly control approximately 30% of the diseases we eventually will acquire, 70% of these conditions can be prevented or remarkably delayed by direct choices we make in our nutrition, activity level, environmental factors and emotional health.” Dr. Joseph Maroon, MD, Longevity Factor, Neurosurgeon for Pittsburgh Steelers
