Why Do We Like Our Own Farts? – Every day, humans generate about 70 billion fart, which means that roughly 10 of them are yours! But why do our own farts do not stink like everyone else’s?
Although it sounds funny, scientists have proved through a test smell with their eyes closed, that we prefer the smell of our own rather than the smell of other people.
Simply put, the more familiar we are with something, whether it be a song, a picture, or even the smell, the more we liked it. And because the population of bacteria that produce the odor in our body differs between individuals, causing fart we have a ‘brand’ (smell) is unique, where only the nose we can distinguish.
Disgust at the smell of other people is a form of self-defense
Seen from an evolutionary standpoint, we are disgusted reaction to the smell of other people the possibility of an attempt by the brain to prevent ourselves from our own bodily harm, especially when interacting with a source of disease.
Coincidentally, most of the objects that odor is usually not good for our bodies, and if the risk of disease caused by the greater, then our response will be more intense. For example, when we see the cat litter in the alleys near the home, automatically your body will try to avoid.
Fart can transmit disease
Surprisingly, it turns out fart can spread the disease. In fact, there are many cases reported that fart spread the bacteria Streptococcus pyogenes, a pathogen that causes tonsillitis (tonsillitis), scarlet fever (scarlet), heart disease and even diseases that can eat your flesh.
This pathogen is issued in the form of matter / particles of dirt in the air. Of course this will only be a problem if we live in naked as our ancestors, while those of us who are now wearing trousers and underpants, fart not be a threat.
We adapt to our body odor
Fortunately we adapt to love the smell of our bodies, so we can clean our body without disgust. By the same token, a mother is not too disgusted to ‘poop’ son, so he can clean it without disgust. (Imagine if all mothers feel disgusted with their droppings).
Of course, maybe some of you “feel that the fart is not at all disgusting thing”, and you are not alone on this. Perceptions of disgust is a combination of several variables such as age, gender, culture, and even personality. It is a very big influence, so anxious person usually more sensitive to smell than people who like adventure and making friends.
Factor ‘surprise’ affect your response to flatus
The anterior cingulate cortex, the part of the brain that processes the sense of shock, was also very influential on your response to flatus, if our own farted, we realized that our brains can anticipate and tolerate the smell. But when someone issued a deadly fart quietly in a crowded room (eg class), expectations about the reality of your brain will be crushed by negative stimuli of the fart smell, so that you smell bad.
So, the next time you feel like a fart, do not be embarrassed to give a warning to the people around you. Unless, of course .., if you are alone, then please have fun with the smell of ‘honor’.
