Published on 13 Dec 2018. "Unhappiness is at the root of more pain, I would suspect, than any ailment that falls in the 'physical' body. And to think that we have compounds that could play such an important role that are really facing challenges in getting approved, I just find that really frustrating." — Dr. Peter AttiaThis is a special episode and features one of my dear friends.A number of guests have started incredible podcasts after being on this show as their first-ever podcast interview, including legendary Navy SEAL commander Jocko Willink.What people don't know is that Jocko was introduced to me by a fella named Peter Attia.Dr. Peter Attia (TW: @PeterAttiaMD, IG: @peterattiamd, peterattiamd.com) is a former ultra-endurance athlete (e.g., swimming races of 25 miles), a compulsive self-experimenter, and one of the most fascinating human beings I know. He is one of my go-to doctors for anything performance or longevity-related. He is also easily the best quarterback and sherpa for the US medical system I've ever met.But here is his official bio to do him justice:Peter is the founder of Attia Medical, PC, a medical practice with offices in San Diego and New York City, focusing on the applied science of longevity.Peter trained for five years at the Johns Hopkins Hospital in general surgery, where he was the recipient of several prestigious awards, including resident of the year, and the author of a comprehensive review of general surgery. He also spent two years at NIH as a surgical oncology fellow at the National Cancer Institute where his research focused on immune-based therapies for melanoma. He has since been mentored by some of the most experienced and innovative lipidologists, endocrinologists, gynecologists, sleep physiologists, and longevity scientists in the United States and Canada.Peter earned his M.D. from Stanford University and holds a B.Sc. in mechanical engineering and applied mathematics.In our conversation in this episode, Peter actually interviews me, though he shares a lot of his own experiences. It is audio from Peter's incredible podcast, The Peter Attia Drive, which can be found on Apple Podcasts, Spotify, or anywhere podcasts are found. It is one of the few podcasts I listen to regularly.Many friends I've shared this particular episode with have now listened to it multiple times. It takes us both a few minutes to warm up, but then it goes really deep. These are many of things people like Peter and I aren't supposed to talk about publicly.Please enjoy!Click here for the show notes for this episode.This podcast is brought to you by Peloton, which has become a staple of my daily routine.

Not long ago, I also interviewed Walter about his writing and Leonardo, as I've known Walter for some time, and the book is spectacular. I think it's his best biography yet, and that's saying a lot considering how famous his bios of Benjamin Franklin, Einstein, and Steve Jobs are.Based on thousands of pages from Leonardo da Vinci's astonishing notebooks and new discoveries about his life and work, Walter Isaacson "reveals an intimate Leonardo" in a narrative that connects his art to his science. He shows how Leonardo's genius was based on skills we can improve in ourselves, such as passionate curiosity, careful observation, and an imagination so playful that it flirted with fantasy. Leonardo da Vinci by Walter Isaacson, published by Simon and Schuster, is available now wherever books are sold.***If you enjoy the podcast, would you please consider leaving a short review on Apple Podcasts/iTunes?
