There were five men and four women in the elevator.
A suspicious smell… A smell without sound… If it
had been a dirty(?) situation, it would have been a sour smell, but this rotten egg smell was clearly pure fart. Who could it be?

The components of farts include air (oxygen/nitrogen) that comes in with food when you eat it, carbon dioxide (CO2) that you breathe in, sulfur dioxide and ammonia that you breathe in through the chemical reaction between digestive fluids and food, and various aromatic gaseous compounds (skatole, indole). And most importantly, various gases (hydrogen, methane) that your intestinal microorganisms produce when they eat food waste are added.

The technology to biochemically produce hydrogen and methane gas has already secured dozens of bacteria and is in the process of commercialization. Hydrogen is produced by bacteria in the intestines of many people, such as Clostridium, Enterobacter, and Klebsiella. In addition, there are more than dozens of bacteria that produce methane gas, and the methane gas emitted by cows is so enormous that it threatens the Earth’s ozone layer.

If your stomach is full of hydrogen and methane gas, it is like a time bomb, so it is better to not hold in your farts as much as possible for your health.

The components that create the smell of fart are mainly aromatic gases called skitol and indole. First, if you look at the molecular formula of skitol, you can see that it has two benzene rings with a methyl group attached to them. If you remove this and attach an amino group, it becomes a perfume that produces a grape-scented scent(!). Also, indole, which creates the savory smell of fart, has a molecular structure similar to strawberry or rose scent and is even used as an ingredient in some perfumes. It is said that
sperm whale feces is also an important perfume ingredient, so farts and perfume may be just a little different.

The difference between the smell of poop and the smell of farts is that poop contains various acids and has a sour smell.
And if the ratio of air is high, you poop often but the smell is not toxic, but if the ratio of air is low and the ratio of meat intake is high, the ratio of ammonia production increases and the smell becomes very toxic. In particular, hydrogen sulfide is a toxic gas and is a toxic gas that caused suffocation and death in old-fashioned toilets and septic tanks.

Men who eat quickly inhale relatively more air, so most of their farts contain more air. They also have shorter bowel movements, so they smell less.
On the other hand, women who like meat inhale less air, so their farts are more pure, so they smell more. If the food they ate yesterday was rich in protein, such as cheese and steak, it’s even worse…
So was the culprit in the elevator earlier him or her?

Most Koreans are a very polite people who don’t make a big fuss about this situation. They know about it but pretend not to know and go to their offices. They may even have a good laugh about farting during morning meetings. Is it a beneficial function of farting?
