What if we could delay--or even prevent--Alzheimer's, cancer, and heart disease? What if much of what you know about aging is wrong? Listen as cardiologist and author Eric Topol of the Scripps Research Institute talks about his new book Super Agers with EconTalk's Russ Roberts. They discuss why your genes matter less than you think, how your immune system can help prevent cancer and Alzheimer's, and why a simple shingles vaccine could reduce the risk of dementia. From the surprising anti-inflammatory powers of Ozempic to the critical importance of deep sleep for brain detoxification, Topol shares insights that can extend your healthy lifespan.
