Do you ever wonder why the smell of your own fart isn’t as offensive as others?
Every single day, humans produce at least 70 billion farts and at least 10 of these come from you. When we smell someone else’s fart, we automatically move away from the direction of the smell as if it’s a deadly epidemic.
But do you know there’s a scientific explanation why we find our own fart more appealing compared to others?
AsapSCIENCE unravelled the science behind it through a short video entitled “Why Do We Like Our Own Farts?”
Scientists have confirmed that humans really do like the smell of their own fart through blind smell tests. According to the scientists, humans tend to prefer something familiar to them and their own bodies.
Our bodies have a unique bacterial population responsible for producing different smells. This means that the smell of our own fart is absolutely unique from others because of our very own fart-producing bacterial population.
Why are we disgusted with other people’s fart?
Now that we know the reason why we can tolerate the smell our own fart, let’s find out why do we find the smell of other’s fart extremely disgusting.
“From an evolutionary perspective, a reaction of disgust to other people’s odour is likely our brain’s attempt to prevent us from doing harm to our own bodies, specifically, interacting with sources of disease.” says the video.
Farts can spread diseases
AsapSCIENCE also revealed that farts are capable of spreading diseases. In fact, one fart can spread Streptococcus pyogene. This pathogen, which is released as fecal matter in the air, is responsible for tonsilitis, heart disease, scarlet fever, and even a flesh-eating disease.
Fortunately, there’s no need for us to run away when someone farts since humans now wear underwears.
