Personal Longevity Practices and Social Factors

Aging is more than disease—it’s the steady decline of function. In this episode of Longevity by Design, Dr. Gil Blander speaks with physicist-turned-biotech innovator Dr. Peter Fedichev about why resilience, not diseases, holds the key to longer lives.

Peter explains how his background in theoretical physics shaped his approach to biology and aging. He outlines why startups, not large institutions, are now leading innovation in longevity science. Drawing from physics, he describes aging as a series of “jumps” between states, each leaving the body more fragile.

The discussion moves from the limits of current drugs to the promise of new approaches. Peter argues that reducing fluctuations and increasing molecular fidelity could unlock far greater gains in healthspan and lifespan. Listeners gain a fresh lens on what drives aging, where the real breakthroughs may come from, and why the next frontier in longevity will require rethinking the problem altogether.
