Episode notes
Longevity Escape Velocity Is Theoretical Now
- Reaching longevity escape velocity is appealing but currently unlikely this century; basics remain most impactful.
- Exercise, diet, sleep and a few supplements currently offer the best chance to extend healthy lifespan.

- Use topical vitamin C, copper GHK and astaxanthin for targeted skin benefits in addition to oral supplementation.
- Combine oral and topical approaches when possible because each route offers different systemic or local effects.

- Compare biomarkers to age peers to gauge health, but aim for age-agnostic 'optimal' ranges when possible.
- Testosterone above ~700 ng/dL associates with lower mortality, but balance many biomarkers, not one alone.
