In this 170th in a series of live discussions with Bret Weinstein and Heather Heying (both PhDs in Biology), we discuss the state of the world through an evolutionary lens. This week we discuss the sun and the Earth. Near Infrared Radiation (NIR) from the sun penetrates deep inside our bodies, where it stimulates our mitochondria to produce subcellular melatonin, a potent antioxidant. Spend time outside to reap the health benefits. And: It is Earth Day! Let us reject reductionism, specialization, and dependence, and remember our roots on the land, making and growing and producing things with our own hands: let us be producers, not merely consumers. Always, we can learn from Wendell Berry. Also: how could the Biden administration be making such a foolish mistake with mortgage rates, why did it take so long for MIT to drop their Covid vax mandates, and how awesome is that spike protein? ***** Our sponsors: Mindbloom: at-home ketamine therapy.
