	Description:		In this episode, Greg and Lyndsey sit down for a discussion about cortisol with Beth Skwarecki, the senior health editor at Lifehacker. The dangers of high cortisol are a persistent topic of content on social media content, so the discussion focuses on the types of claims that are being made, the dubious methods of self-diagnosis and “treatment” being recommended, and the potential risks and dangers associated with letting social media convince you that you’re basically an endocrinologist.
