In this episode of Longevity by Design, host Dr. Gil Blander sits down with Dr. Nathan Price, Professor and Co-Director at the Buck Institute for Research on Aging. Together, they explore how systems biology, artificial intelligence, and deep health data are changing the way we approach aging and prevention. Nathan explains why looking at single biomarkers falls short and why a network view of biology gives a clearer path to understanding disease and resilience.

Nathan shares how new tools, like genetics, proteomics, and the emerging field of digital twins, can help predict disease risk years in advance and guide more effective, personalized interventions. He also discusses how integrating data from wearables, blood tests, and the microbiome can help people move from reactive medicine to proactive health decisions, allowing for interventions that fit the individual.

The conversation highlights the promise and practical limits of current technologies, the trade-offs involved in optimizing health, and the power of AI to accelerate both research and personal health journeys. Nathan makes a strong case for the unique biology each person brings to the table and shows how the tools available today can help anyone take charge of their own healthspan in ways not possible before.
