Longevity & AgingPeter Fedichev Says Three Variables May Explain How and Why We Age
Peter Fedichev, CEO of Gero, proposes that aging can be understood through just three variables: stress, damage, and physiological noise. Rather than cataloguing dozens of hallmarks, this minimal model may better predict aging trajectories and why interventions succeed or fail. Fedichev argues most current longevity therapies are 'level 1' — they reduce damage or stress but don't address the deeper instability driving biological aging. He also highlights a fundamental difference between how mice and humans age, suggesting findings in rodents may not translate cleanly to humans. The conversation covers whether replacing damaged tissues can genuinely reverse aging, the concept of 'effective temperature' as a measure of biological noise, and how AI could accelerate drug discovery for longevity. A thought-provoking framework for anyone tracking the science of aging.
