In this 102nd 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.Beginning with a discussion of health and illness, followed by ads for our sponsors, we then launch into discussion of vitamin D deficiency and Covid comorbidities; a new study in The Lancet which finds that, if infected with Covid, vaccinated people transmit at the same rate as do unvaccinated people; and the prospect of vaccinating 5–11-year-olds against Covid. Finally, we discuss the wisdom of Nobel laureates: on tinkering, giving students difficult problems, and the value of discomfort.Get your Goliath shirts right here: store.darkhorsepodcast.orgHeather’s newsletter, Natural Selections (subscribe to get free weekly essays in your inbox); next post: zombies https://naturalselections.substack.com*****Support the sponsors of the show:HoMedics: Air purifiers that live up to expectations.
