This hour, we dive into the messy mystery in the middle of us. What's going on down there? And what can the rumblings deep in our bellies tell us about ourselves?

We stick our hand in a cow stomach, get a window into our core (thanks to a hunter who became a walking science experiment in the 1800s), and listen in on the surprising back-and-forth between our gut and our brain. And we talk to a man who kind of went out of his mind when a medical procedure left him (for a little while) gutless.
