A weird study just came out finding that head-up sleeping may increase red blood cell totals. We talk about what it means and what it doesn’t mean. Excuse us while we launch a cinderblock start-up. We also discussed a breakthrough in gene editing for cholesterol, and what that could mean for the future. The world is going to be so different in 50 years! Maybe by then, David can use CRISPR to be able to pronounce science words. And this one was full of fun topics! Other topics: our training log discussions, iron levels in athletes, breaking news on heat training from Unbound 200, a science debate on fatigue resistance terminology, and a study on glucose v. fructose. Plus, we answer questions on heat training in the car, clean sport for age group athletes, marathon v. ultra training, and health uncertainty. You’re going to learn a lot about what Megan would do for 40 grams of carbs. Totally normal stuff if you ask her! We love you all!
