How to Live to 100 (or Die Trying): The grim news about your biological age

The longevity gold rush is underway and we hear about the latest reasons for optimism and cynicism from Steve Horvath, the developer of a 'biological clock' that is mostly used by researchers or, the curious, although some experts question whether such measurements are ready for prime time. Horvath explains the science behind his clock, the centenarian connection and the food he says can keep our biological age low.

Guest: Steve Horvath is a biogerontologist, whose research lies at the intersection of epigenetic biomarkers of aging, preclinical and clinical studies, genomics, epidemiology, and comparative biology.
