Summary: Get to know Mark, his background, and his entrepreneurial spirit like never before! Mark Sisson has been a great friend and mentor of mine for 30 years. As one of the founding fathers of the primal/paleo/keto/ancestral health movement, Mark has probably been on a couple hundred podcasts, including perhaps a dozen of our own for Primal Blueprint and Primal Endurance shows (listen to the very first Primal Blueprint podcast, published December 30, 2013, where he talks about the dangers of chronic cardio.)
