Dr. Jack Kreindler joins the show to discuss longevity, human performance, physiological medicine, and what it truly takes to preserve vitality as we age. Together, we explore why longevity should go beyond disease prevention and quick fixes to focus on building the physical capacity, resilience, and independence needed to thrive throughout life.

We dive into:

  • Redefining longevity around vitality, healthspan, and physiological capacity
  • What extreme environments and human performance science can teach us about aging
  • Using VO2 max, body composition, and functional assessments to understand health trajectories
  • Why treating everyday patients more like athletes can support long-term performance
  • Building strength, mobility, and resilience to maintain independence with age
  • Why foundational physiology should come before peptides and other longevity interventions
  • GLP-1s, emerging therapies, and the importance of thoughtful risk management
  • The limitations of quick fixes and longevity trends popularized on social media
  • How clinicians can incorporate performance science and physiological medicine into patient care
  • Why preserving physical and cognitive function is central to a meaningful approach to longevity
