Fair to say that we all assume that aging is inevitable. In reality however, there is no biological law that says we must age. Over the years we’ve seen a variety of theories proposed to explain why we age including the accumulation of damage to our DNA, the damaging effects of chemicals called “free radicals,” changes in the function of our mitochondria, and so many others. Our guest today, Dr. David Sinclair, believes that aging is related to a breakdown of information. Specifically, he describes how, with time, our epigenome accumulates changes that have powerful downstream effects on the way our DNA functions. Reducing these changes to the epigenome is achievable and in fact, even taking it further, his research now reveals that the epigenome can be reprogrammed back to a youthful state. David A. Sinclair, PhD, AO is Professor of Genetics at Harvard Medical School, and is the author of Lifespan: Why We Age–and Why We Don’t Have To. He is the Founding Director of the Paul F. Glenn Center for the Biological Mechanisms of Aging at Harvard. One of the leading innovators of his generation, he is listed by TIME magazine as one of the “100 most influential people in the world” (2014) and top 50 most important people in healthcare (2018). He is a board member of the American Federation for Aging Research, a Founding Editor of the journal Aging, and has received more than 35 awards for his research on resveratrol, NAD, and reprogramming to reverse aging, which have been widely hailed as major scientific breakthroughs and are topics we discuss in our time together. In 2018, Dr. Sinclair became an Officer of the Order of Australia, the equivalent of a knighthood, for his work on national security matters and human longevity. Dr. Sinclair and his work have been featured on 60 Minutes, Today, The Wall Street Journal, The New York Times, Fortune, and Newsweek, among others.  In closing, I really need to say that Lifespan ranks as one of the most influential books I have ever read.
