In this episode, I am speaking with Dr. James Chestnut for the third time, we talk about why healthspan is, by far, more important than lifespan and the biggest keys to optimizing healthspan. In this podcast, Dr. Chestnut and I discuss: Lifespan vs healthspan (what is the difference and how do they matter?) The shocking lack of evidence for medication extending the lifespan of older adults The reasons why modern medicine doesn’t work for chronic disease How most practitioners within the Functional Medicine movement miss the root causes of illness Keys to making effective lifestyle changes (despite the natural resistance)
