In this episode, Dr. Ezekiel Emanuel, world-leading oncologist, bioethicist and World Health Organization adviser, shares six rules from his book Eat Your Ice Cream (https://amzn.to/4wu8faa) that may help lower your risk of dementia, heart disease, cancer and early death. Ezekiel explores the science of healthy ageing, longevity and disease prevention, and explains why many wellness trends distract us from what matters most. By the end of the episode, you’ll have six practical habits that have the biggest impact on living well for longer. From building stronger relationships and staying mentally active to improving your diet, exercise and sleep, Ezekiel offers a simple framework designed to support health over decades, not weeks.
