“Age Reversal Is Coming.” Inside The First Human Trials - Dr David Sinclair - #1141
Summary
Hosts revisit their 2019 meeting to discuss David Sinclair’s breakthroughs in reversing aging using Yamanaka factors, now entering human trials for blindness. Sinclair explains the epigenetic theory of aging and reveals a new oral pill that rejuvenates mice. He also advises on longevity practices, including fasting, calorie restriction, and balancing protein intake to activate survival mechanisms.
