#357 ‒ A new era of longevity science: models of aging, human trials of rapamycin, biological clocks, promising compounds, and lifestyle interventions | Brian Kennedy, Ph.D.
The Peter Attia Drive
Brian Kennedy is a renowned biologist, leader in aging research, and director of the Center for Healthy Longevity at the National University of Singapore. In this episode, Brian shares insights from ongoing human aging studies, including clinical trials of rapamycin and how dosing strategies, timing, and exercise may influence outcomes. He presents two key models of aging—one as a linear accumulation of biological decline and the other as an exponential rise in mortality risk—and explains why traditional models of aging fall short. He also explains why most current aging biomarkers lack...
