The structural reasons the supplement aisle rarely matches the press releases: preclinical models, dose gaps, and endpoints that never move.
Read →The Longevity Escape Velocity Debate
A provocative idea examined against demographic evidence that life-expectancy gains are slowing rather than accelerating away.
Read →Purpose and Lifespan: The Psychological Evidence
Purpose in life tracks with lower mortality across large cohorts. What that observational finding can and cannot establish.
Read →Social Connection and Longevity
A 148-study meta-analysis tied stronger social ties to 50% higher odds of survival. Why the effect is large, and what the caveats are.
Read →VO2 Max and Lifespan: The Most Underrated Longevity Marker
