Americans spend more on healthcare than other developed nations. So why are we not the healthiest country on Earth? Sandro Galea, dean and Robert A. Knox Professor at the Boston University School of Public Health, joins host Krys Boyd to talk about how we should rethink our understanding of what it means to be healthy – and how that shift will guide our approach to healthcare. His new book is called “Well: What We Need to Talk About When We Talk About Health” (Oxford).
