Longevity & Healthy Aging
Living longer, living better
The science of extending healthspan — the number of years we live in good health, not just the total years. From cellular senescence to lifestyle interventions, this is one of the fastest-moving areas of medical research.
Why It Matters
For the first time in history, lifespan is declining in parts of the developed world. Yet we're also seeing unprecedented breakthroughs in understanding how aging works at the cellular level. The goal isn't immortality — it's living the last 20 years of your life with vitality instead of decline. What you eat, how you move, how you sleep, and what supplements you take (or don't) all matter more than we used to think.
Questions I'm Exploring
"Which longevity interventions actually have evidence behind them?"
"Is rapamycin worth the risk for healthy adults?"
"What can we learn from Blue Zones without moving to Okinawa?"
"How do we separate longevity science from longevity marketing?"
