About this Episode
Opening with Anne Lamott's beautiful quote about age providing "the time and experience and failures and triumphs" that shaped her into who she was meant to be, this episode transforms how listeners view aging. Dr. Mark Klein makes a stunning scientific argument: aging is completely unnecessary. DNA could theoretically be written so that no cell ever ages or dies. The fact that it isn't - in this particular universe - is a profound clue about our purpose. Through the jukebox of time metaphor, Dr. Klein explains that we don't actually "age" in the traditional sense - we simply move to different pages of our life's book, while all previous pages continue existing simultaneously.
