Today Paul Pepper visits with OLEN BROWN, author of the book, "Oxygen, the Breath of Life: Boon and Bane in Human Health, Disease, and Therapy." Olen, a professor emeritus at the Dalton Cardiovascular Research Center at the University of Missouri, wrote this book because, as he says, "my real desire has always been science, but also communication of science. I like to help people understand it." June 2, 2017
