In our never-ending quest for the fountain of youth, people will try all sorts of gimmicks and products that promise eternal vitality and radiance. However, true longevity isn't about chasing fads - it's about understanding the science of how our bodies age and making lifestyle choices that promote healthspan as well as lifespan. My guest today is Bill Gifford, an author who has dedicated years to researching this fascinating topic.  Bill has teamed up with Dr. Peter Attia to author the runaway hit called 'Outlive: The Science & Art of Longevity' - a manifesto that has sold over a million copies by redefining how we approach healthcare and pursue wellness over merely treating diseases." One of the book's central theses is that "The way we approach healthcare must undergo a fundamental shift from Medicine 2.0 to what they’re calling Medicine 3.0. Medicine 2.0 is about diagnosing and treating illnesses, while Medicine 3.0 is about preventing disease and promoting wellness, ultimately extending not only lifespan, but also healthspan.  Get ready to take some notes, because today’s conversation will be a roadmap for taking charge of your longevity.
