The average lifespan of Americans has increased approximately two years per decade over the last century. While we are living longer, we are also suffering more from the chronic diseases of aging, like Alzheimer’s, Parkinson’s, and cancer, than ever before. While many view this type of decline as inevitable, the scientists at the Buck Institute, the nation’s first independent research facility focused solely on understanding the connection between aging and chronic disease, believe that people should enjoy life at 95 as much as they do at 25. Toward that end, they are using cutting-edge research to discover how to improve health span, or the healthy years of life.
