How Does My Butt Tell the Difference Between a Fart and Poo?

Each day, your body makes the high-stakes decision that holds together the very fabric of our society… “is that just a fart, or am I about to shit myself?” And with the average person releasing nearly a half gallon of gas a day, your body is making this decision all the time.

Turns out, this impressive ability all comes down to how we developed as an embryo. 

We explore biology behind farts to uncover how society as we know it is held together by a few centimeters of tissue in our anus, all while answering even more fart questions along the way. That’s what you’re in for today, on Impolite Society.
