Is measuring your “biological age” really the key to living longer or just clever marketing?
In this fascinating debate, three leading voices in longevity, Dr. Matt Kaeberlein, Dr. Aubrey de Grey, and Dr. Gordan Lauc, join Julian to unpack what it really means to measure aging and whether modern “biological clocks” actually tell us anything useful to the great challenges facing longevity moving forward.
The conversation goes beyond the hype to address the future of preventative medicine, the limits of today’s health technology, and how AI and personalized data could reshape how we measure and maintain our health. Together, they challenge the idea of “one number fits all,” arguing instead for a holistic approach that blends biomarkers, lifestyle insights, and clinical-grade precision to build a healthier, longer-lived population.
