We assume that we know the answer to the question, Why does the body age? In short, we age, and eventually die, because we live. But what can we learn from studying aging on a cellular level? Host Dr. Mary Leuchars talks with Dr. Steven Austad, professor of cellular and structural biology at the Barshop Institute for Longevity and Aging Studies at the University of Texas Health Science Center at San Antonio and research chair of the American Federation for Aging Research, about why humans age, why we age, how to extend longevity, and the ramifications of extending our lives.
