Cross-Species Clues To Aging
- Different species show varied aging because they resist metabolic and molecular damage differently.
- Stephen Austad argues we can learn mechanisms from long-lived animals to improve human healthspan.
Metabolism vs. Movement Paradox
- Slow metabolism correlates with long lifespan across many species but doesn't negate exercise benefits in humans.
- Austad notes turtles' slow heartbeats link to longevity while human exercise still promotes healthspan.
Keep Moving For Healthspan
- Exercise remains a top intervention for longer, healthier human lives.
- Austad calls exercise a 'miracle drug' for maintaining health into old age.
