Microbiologist Dr. B. Brett Finlay and health geographer Dr. Jessica Finlay challenge conventional wisdom about aging by highlighting the crucial role of microbes in our health. In their new book "The Microbiome Master Key," they explore how nurturing our inner ecosystem can promote longevity, brain health and overall well-being. Then, Park City based writer, comedian and blogger Jena Kingsley discusses her new book, “Darcy Dates,” based on her blog that chronicles the experience of dating in New York City post-divorce. It's raw, real and hilarious.
