My guest this week is Dr. Peter Attia. I’ve had Peter on the show twice before but it’s been over 5 years since his last appearance. In that period, his work has exploded and today he’s one of the clear leaders on the topic and practice of longevity and health span. He has a new book out called Outlive, which I heartily recommend. You’ll hear us refer to the last chapter of his book early in our conversation but we chose not to reveal the whole story live so you can read and enjoy it. We highlight the big picture in our conversation, including the transition from Medicine 2.0 to Medicine 3.0. I always leave these conversations with Peter full of ideas, and in this case, highly motivated to go outside and move my body in nature. I can think of no better actionable advice. Please enjoy my conversation with Peter Attia.
