Farting is hilarious and gross and everyone is doing it so why can’t we talk about the science of it?! Flatulence, passing gas, cutting the cheese, toots… whatever you call it, it’s natural. Humans pass gas about 20 times a day on average, and collectively, we fart about 7 billion liters of gas each day!
Here’s how it works. Farts are either the result of trapped, swallowed air being expelled from the body, or as byproducts of the microbes living in your gut.
In this episode of It’s Okay to Be Smart, learn how the average height of humans changed over time due to agriculture, migration, and industry. And learn while genes cause growth spurts.
For more great information on farts, read Does it Fart?, written by Nick Caruso and Dani Rabaiotti.
It’s Okay To Be Smart is hosted by Joe Hanson, Ph.D.
