Guest
Greg Bailey
Dr. Greg Bailey, a former ER physician turned biotech investor and longevity researcher, explores cutting-edge science and practical longevity. He discusses cellular reprogramming, epigenetic age reversal, bioelectric limb and organ regrowth, AI-driven drug discovery, and the pros and pitfalls of ketones, supplements, and regenerative therapies. Short, thought-provoking, and forward-looking.

Episode notes
INSIGHT

Healthspan Over Lifespan

  • Longevity should prioritise healthspan over lifespan by focusing on staying healthy, not just living longer.
  • Greg Bailey founded Juvenessence to increase years lived in a youthful physiological state rather than extended frailty or disease.
INSIGHT

Reprogramming Cells To Reverse Aging

  • Breakthroughs like epigenetic reprogramming, CRISPR, and limb/organ regeneration are making aging modifiable.
  • Greg highlights work by Mike Levin (bioelectric signals) and early epigenetic reversal as signs we can reprogram cells without causing cancer.
ANECDOTE

Mike Levin Regrew A Frog Leg

  • Greg recounts contacting Mike Levin and learning Levin regrew a frog leg and later a mouse digit using bioelectric signals.
  • He uses that example to show organ or limb regrowth is moving from sci‑fi to lab reality.
