Could aging be an information problem rather than simple wear and tear? Explore epigenetics, cellular repair, longevity genes, and the surprising effects of fasting, exercise, heat, and cold. The discussion also examines experimental drugs, the risks of resetting cells, and the social consequences of dramatically longer lives.

Episode notes
Aging Is The Root Cause Behind Major Diseases
- Treating cancer and heart disease separately extends lifespan only modestly because aging raises the risk of them all.
- Modern medicine has lengthened lifespan more effectively than healthspan, leaving people alive but increasingly frail.
Aging Scrambles Instructions Rather Than DNA
- Aging may reflect lost epigenetic information rather than destroyed genetic instructions.
- An old cell still contains its youthful blueprint, like an intact DVD that a scratched laser can no longer read clearly.
DNA Repairs Can Distract The Longevity Crew
- Sirtuins leave their normal posts to repair repeated DNA breaks, gradually disrupting which genes stay active.
- Cells eventually lose their identities because short-term survival repairs create long-term epigenetic drift.
