My guest this week is Peter Attia, M.D., whose mission is to understand and improve human lifespan and healthspan (or quality of life).  Reading Peter’s research, you find that there are many similarities between health and investing—ideas like compounding—which we explore in detail.We spend a lot of time on mind, body, spirit and performance as it relates to living a better life. Of particular interest is the strategic problem that we face when studying longevity. As Peter puts it in our conversation: we are the species of interest, but we can’t conduct the kinds of experiments on humans—randomized trials, with control groups—that we apply to solve other big problems. So we have to back our way into a better understanding of longevity and quality of life.To that end, we discuss what we can learn from studying centenarians, the problem of progress in science, a drug called Rapamycin (which Peter believes could be revolutionary), eating, the importance of muscle mass, and the idea of distressed tolerance.  We emerge with a framework for thinking about health and well-being which can hopefully help us all live longer, better lives.
