In this Deep Dive episode we explore the book by Dr Graham Simpson with Foreword by Dr. Alan Barnard, called "Era III Medicine": a framework that integrates body, mind, and spirit to increase not just lifespan but healthspan. Dr. Graham Simpson, a pioneer in longevity and Dr. Alan Barnard, a pioneer in Theory of Constraints, argue that metabolic dysfunction is the primary constraint in body and mind  health. The episode contrasts Era I (biological medicine) and Era II (mind-body approaches) with Era III, which treats consciousness as fundamental and emphasizes integration, practical experiments, and measurable biomarkers as part of a pathway to flourishing.

The authors propose a three-step experiment covering each of the 3 Eras of medicine to increase health span and life span:

For Era I: clean fuel (diet), For Era II: heart-brain coherence, and For Era III: meditative connection to the biofield—to restore metabolic flexibility and reduce the fear of death.
