I compared 50+ biomarkers across three very different approaches to longevity:
- Siim Land (29): Younger and heavy training
- Me, Crissman (53): Minimal interventions
- Bryan Johnson (47): $2M yearly spend and over 100 supplements
Each of these paths has strengths, but the comparison shows how far the fundamentals alone can take you.
Youth carried the day, but my minimalist approach had overall better biomarkers than Bryan Johnson, despite being six years older.
