In this episode of New Frontiers, Dr. Kara Fitzgerald sits down with longevity physician Dr. David Barzilai to separate promising science from hype and explore where the field of longevity medicine is headed.
They discuss the evolution of biological age testing, including DunedinPACE and other aging clocks, and why these tools can provide useful information without telling the whole story. They also explore how AI and emerging technologies could transform personalized medicine, helping clinicians better identify which interventions may actually benefit an individual.
You’ll also hear why the fundamentals still matter, how to think critically about the growing number of supplements and longevity “hacks,” and which emerging interventions deserve attention as the science evolves.
In this episode, you’ll learn:
- What biological age and aging clocks can—and can’t—tell us
- How to distinguish promising longevity science from hype
- Why slowing the rate of aging may matter more than chasing a biological age number
- How AI could change personalized longevity medicine
- Why individualized diet, exercise, sleep, and other foundational interventions still come first
- How clinicians can evaluate emerging longevity therapies without getting ahead of the evidence
- Where longevity and geroscience may be headed next
If you’re interested in biological aging, healthspan, precision medicine, or the future of longevity science, this conversation offers a practical look at what we know today—and what may be coming next.
