This chapter discusses the evolution of medicine from an era based on religious beliefs to the development of the scientific method and randomized control trials. It highlights the progress in treating infectious diseases and acute injuries, while also addressing the challenges in managing chronic diseases. The chapter explores the factors contributing to longer lifespan, the measurement of health span, and the importance of genetics in determining health risks.
We spend too much of our health care focus on lifespan and not enough on healthspan--the quality of our life as we get older. So argues Dr. Peter Attia, author of Outlive: The Science and Art of Longevity. Attia speaks with EconTalk's Russ Roberts about what kills us, what slows us down as we age, and the weapons we have to allow us to live better and longer.
