Farts are weird. It seems perfectly fine when we let one rip, despite the stink bomb it may be. We can tolerate our own, but if someone else cuts the cheese? Aw, heck no. Theirs is unbearable.
Okay, we know what you’re thinking: “Gross, this is science?” and “Shoot, how did they know?” Yes, and we just do because we’ve all been there. Farting is a perfectly normal (and necessary) function of our glorious human bodies. Gas builds up in our intestines for a number of reasons. It could be from inadvertently swallowing too much air, the by-products of bacteria that live in our gut and help us digest food, or chemical reactions in the gut. All of that gas has to be let out somehow. Basically, it’d be weird if you didn’t pass gas at all!
Leave it to AsapSCEINCE to help answer some of life’s most pressing questions in a way that doesn’t stink. In the video, they suggest that we may “prefer” the smell of our own farts because it’s both familiar and contains a genetic signature that is unique to each of us. Interestingly, your tolerance to farts in general are based on other factors such as age, culture, and personality as well. Check out AsapSCIENCE’s video above for more.
