Reason with Science Evolutionary aspects of ageing | Steven Austad | Reason with Science | Lifespan | Human health
This episode is with Steven Austad. He is the Protective Life Endowed Chair in Health Aging Research, a Distinguished professor and Chair of the Department of Biology at the University of Alabama at Birmingham. Steven has been at the forefront of unraveling the mysteries of why some individuals live longer and healthier lives than others. His work covers a diverse array of topics, from the cellular mechanisms of aging to the evolutionary aspects of longevity in various species. In this conversation we talk about what is ageing?, biggest challenges in the field of ageing, evolutionary aspects of ageing, chronic illnesses and how to increase human life span?
