It’s almost hard to believe, but in the 1950s doctors were frequently portrayed in TV commercials for. . . cigarettes. That’s because smoking wasn’t just seen as cool and glamorous, but as an actual health-enhancing activity. Fast-forward to today, and Americans have been sold on a dizzying number of health trends: from grapefruit diets and Weight Watchers to Pelotons and yoga. The health industry churns through information and fads faster than anyone can possibly keep up. As soon as you’re gearing up to start a juice cleanse or go on a Costco rampage for keto-friendly ingredients, a new diet, a new drug, a new piece of equipment shows up to tell you out with the old, in with the new: here is the real key to your health. One person who consistently cuts through all that noise is Dr. Peter Attia. His new book, Outlive: The Science & Art of Longevity, is a blueprint—based on the best available science and data—for what really matters to live a healthy life. And not just a healthier one, but a longer one. Attia is a Stanford- and Johns Hopkins-educated, NIH-trained physician who is at the forefront of some of the most important conversations around health and longevity in medicine today. His work is at the center of a new industry that has been booming in Silicon Valley for the past several years. Tech giants like Jeff Bezos, Peter Thiel, Sam Altman, Larry Page, and Brian Armstrong have poured billions into start-ups that research human life extension. But Attia doesn’t think this is only for the elites of Silicon Valley. He thinks there’s a well of everyday changes—from what we eat, how we move, and how much we sleep, to scans, blood tests, and other early interventions, to our emotional health—that can give people extra years to the very short life we have here on earth. On today’s episode: what’s possible in the uncharted science of longevity? And—from our broken medical system to our truly unhealthy lifestyles—what are the major factors preventing us from living longer, healthier lives? And what makes a life worth living anyway?
