Thirty-five years ago, a misdiagnosis landed me in the hospital and resulted in a colon resection that cost me a foot of my colon. That painful detour became the best thing that ever happened to my health. It introduced me to a world-renowned holistic practitioner and, several years later, to my wife — an equally respected integrative medical practitioner. What started as crisis recovery evolved into decades of immersion in functional medicine. Along the way, I discovered the Blue Zones, those remarkable regions where people routinely live past 100 with sharp minds and strong bodies.
