In this episode, Greg Dickens and I discuss recent news on picky eating in adolescence, on childhood exposures that increase the risk of bowel cancer, and on how the gut develops tolerance to potential allergens. We then talk about why everyday pains are so important for children, what allows them to experience these pains, and why mildly painful rites of passage can help children to learn to manage their own pain. Finally, we discuss the effects of humming on airway health.
