In this episode of Longevity By Design, Dr. Gil Blander interviews Dr. Bartek Nogal about genetic predispositions to conditions of aging. This episode goes deep into explaining how to improve your healthspan using DNA insights. Dr. Blander and Dr. Nogal talk about bone mineral density, epigenetic age acceleration, cognitive decline, risk of elevated ApoB, grip strength, and more. Knowing your genetic predispositions to certain traits can help you fine tune your wellness plan, and Dr. Nogel and Dr. Blander explain how to do so in this episode.Episode timestamps:
