Sep 25, 2025 Join Matt Kaeberlein, a molecular biologist and expert on aging, as he dives into fascinating longevity biomarkers and how they can influence healthy aging. He discusses the crucial differences between lifespan, health span, and ‘sick span.’ Kaeberlein emphasizes the importance of emotional health and community in longevity while critiquing the practicality of certain cellular tests. He also highlights lifestyle changes that can dramatically improve health span and shares insights on protein intake, exercise priorities, and the potential of the drug rapamycin.

Episode notes
Biological Age Tests Are Risk Estimates
- 'Biological age' tests measure correlates of risk, not a true single biological age.
- These clocks estimate current health status or mortality risk but do not measure a direct mechanistic age.
Relationships Impact Biological Aging
- Emotional health and social connection materially affect physiological aging and disease risk.
- Loneliness and bereavement produce measurable increases in morbidity and mortality.
Be Skeptical Of Direct-To-Consumer Tests
- Treat advanced consumer cellular tests and microbiome panels with caution; they often lack validation.
- Prefer clinically validated blood tests and actionable biomarkers tied to clear next steps.
