About this episode
Everybody poops. But why? To find out, science writer Mary Roach takes us on a journey into the alimentary canal - that's the tube that runs from our mouth to our rectum. Along the way, we learn about pooping in space, and how someone else's poop might one day save your life! We love all science here at Tumble, but poop science holds a special place in our hearts. We hope you enjoy this extended cut of “The Secret Life of Poop” where we learn more about why poop is not only funny, but important to our health.
