"None of these tools can replace the fundamentals," Dr. Mark Hyman says early in this episode, and that sentence is the thesis for everything that follows. The longevity industry has exploded with cold plunges, supplements, peptides, hyperbaric chambers, and elaborate morning routines. Hyman uses many of these tools himself.

- 1 (00:00) **Introduction: The Longevity Industry vs. the Fundamentals** - Dr. Hyman frames the episode by acknowledging the appeal of biohacking tools (cold plunges, supplements, wearables) while arguing they are worthless without mastering exercise, sleep, diet, and metabolic health.

- What the science really says about red wine, genetics, and the factors that shape how you age
