This episode is with John Tregoning, a leading expert in infectious diseases, professor at Imperial College London, and author of the books “Live Forever?” and Infectious. John’s work focuses on how our immune systems fight off disease and how scientific advances can help us live not just longer, but healthier lives. In this episode, we break down the science behind ageing and talk about the growing role of vaccines, lifestyle, and cutting-edge technologies like AI, gene editing, and immunotherapy in transforming how we think about health. We also touch on some big-picture questions like What are the ethical and social implications of radically extended lifespans? And what can we do right now to stack the odds in our favor for a longer, more vibrant life?
