Filmmaker David Donnelly joins us to discuss his new documentary Forever Young, an exploration of the rapidly advancing science of longevity. What began as a skeptical investigation into whether the hype around anti-aging breakthroughs was real ultimately revealed a growing body of research focused on extending healthspan and preventing disease. We examine what the science supports today, from the role of prevention and lifestyle to emerging therapies now entering human trials. Along the way, David raises larger questions about purpose, social connection, and how society must adapt as people begin to live longer and healthier lives. Special Thanks to Our SponsorsOur Place: The top cookware brand for beautiful, non-toxic, PFA-free pots and pans.

Judi Wineland, world traveler and founder of AdventureWomen explains how a lifetime of extreme travel shaped her idea of “aliveness,” and why the right trip can change your relationship to your body, your confidence, and your attention. She breaks down what happens when women travel together without the labels and expectations they carry at home, and why that can unlock sharper honesty, better friendships, and a renewed sense of play. You’ll hear how awe, discomfort, and laughter become practical tools for building resilience, whether you’re walking an old pilgrimage route in Japan or feeling tiny on the Serengeti. If you want a clear-eyed take on how travel can support wellness, fitness, and personal momentum at any age, this episode is a blueprint. Special Thanks to Our SponsorsFatty15: C15:0 is the first essential fatty acid to be discovered in over 90 years, and Fatty15 is on a mission to optimize your C15:0 levels to help support your long-term health and wellness—especially as you age.

Most people focus on how much protein they eat, but Oliver Amdrup-Chamby, founder of health and wellness supplement brand Puori, argues the bigger question is whether your protein source is potent enough to support muscle as you age, and clean enough to use daily. He explains why leucine matters for muscle protein synthesis, and why plant and animal proteins can look very different once you factor in calories, volume, and digestibility. Then the conversation turns practical: what “third-party tested” should actually mean, why powders can concentrate contaminants, how to see through BS marketing, how to avoid toxins and more. Special Thanks to Our SponsorsOur Place: The top cookware brand for beautiful, non-toxic, PFA-free pots and pans.
