Throughout his career, Dr. Steven Austad has been exploring aging, longevity, and life extension in a variety of animals. He has written multiple books, including “Why We Age: What Science Is Discovering about the Body’s Journey Through Life” and “Methuselah's Zoo: What Nature Can Teach Us about Living Longer, Healthier Lives.” In this interview, Dr. Austad discusses the topic of longevity and the progress being made toward curing some of humanity’s most devastating diseases - specifically heart disease, cancer, diabetes, and neurodegenerative conditions like Alzheimer’s. He shares his belief that humanity is on track to make cancer a managed disease. Dr. Austad talks about new drug discoveries made in the last four years that should dramatically improve our ability to fight our most devastating diseases and he even talks about the surprising benefits being realized from the use of popular weight loss drugs. He goes on to address how science has effectively extended life over the last 125 years, but many people who are going to live much longer haven’t changed their attitudes and expectations about their retirement age. Dr. Austad has dedicated his career to understanding the science of how and why we age. He is a distinguished professor and Protective Life Endowed Chair in Healthy Aging Research at the University of Alabama at Birmingham. He has done field research in The United States, Venezuela, East Africa, Micronesia, and Papua New Guinea. Dr. Austad’s books include “Why We Age: What Science Is Discovering about the Body's Journey Through Life” and “Methuselah's Zoo: What Nature Can Teach Us about Living Longer, Healthier Lives.”
