RadioLab is one of my favorite NPR shows, and I wanted to share their episode called "Guts". I loved it! Like all of their shows, it consists of three stories around a central theme, this one being "guts" as the name implies. The final story really stuck with me - it's funny, touching, and compeltely incredible, about a man with Crohn's disease. I attached the weblink below to "Guts", but check out the other episodes as well. They're all free to listen to and download. Enjoy!
