What if aging isn't something that simply happens to us, but something we can actually influence? Dr. Poynor is joined by Dr. Eric Verdin - the President and CEO of the Buck Institute for Research on Aging, the world's first institution dedicated solely to understanding why we age and how to do it better.

We break down the science behind why we age, the role of NAD in cellular energy and repair, how inflammation quietly accelerates decline, and what metabolism has to do with how long and how well we live. 

Dr. Verdin also walks us through what the latest research says about what we can actually do today—from how we eat and exercise, to the emerging interventions that may one day change the trajectory of aging altogether. He also shares which interventions he’s tried himself and what he’s chosen to skip altogether.

Although epigenetics has been studied for decades, a major breakthrough came in 2013, when geneticist Steve Horvath, PhD, developed the first widely applicable epigenetic clock—a DNA methylation-based biomarker that estimates biological age across multiple human tissues. https://link.springer.com/article/10.1186/gb-2013-14-10-r115

A landmark 2026 Science study found that human lifespan heritability is roughly 50%, more than double earlier estimates — once researchers separated deaths from external causes (accidents, infections) from deaths driven by intrinsic aging biology. https://www.science.org/doi/10.1126/science.adz1187
