raise your hand if your fart smell good.

yang angkat tangan tu berdose coz menipu. haha. farts will never smells good. some people said if kentut ade bunyi, tak bau. then if bunyi pulak tak de, bau busuk hangit fulamak! ade ke camtu? plus, don't you know that animals farts too. dulu my cousin selalu cakap "eww. ashy (nama kucing) kentut busuk!". I thought she was joking around. but when I did some research, I found a fact that even cat and dogs farts smell bad too. here I'm going to share some facts about fart! :B

Where does fart gas come from?

These gases come from several sources: air that is inhaled, the air absorbed into the stomach from the blood, gas produced from chemical reaction in stomach and the gas generated by bacteria living in the stomach.

What makes farts stink?

Farts odour consists of a mixture of hydrogen sulfide and mercaptan. More diet consisting of sulfur, the more sulfides and mercaptans will be produced by bacteria in the stomach and more foul smell farts. Example: a boiled egg. Pulses will produce a smelly fart, but in large numbers. 

Why do farts make noise? 

The sound produced due to vibrations in the anal opening. Sounds depend on the velocity of the gas and the tightness of the anus muscle. Fart noise is not generated by the flapping of the butt cheeks. This is a mistake. 

Why do farts smell is usually warmer and quieter than regular farts? 

Most fart gas comes from swallowed air and consists largely of nitrogen and carbon dioxide, the oxygen having been absorbed by the time it reaches the anal opening. These gases are odorless, although they often pick up other (and more odiferous) components on the way through the bowel. They emerge from the anus in fairly large bubbles at body temperature. Another major source of fart gas is bacterial action. Bacterial fermentation and digestion processes produce heat as a byproduct as well as various pungent gases. The resulting bubbles of gas tend to be small, hot, and concentrated with stinky bacterial metabolic products. These emerge as the notorious, warm, SBD (Silent-But-Deadly), often in amounts too small to produce a good sound, but excelling in stench.

How many times a person fart a day? 

On average, a person can produce half a liter of fart gas per day, divided into about fourteen daily farts. Although it is difficult to measure the volume of wind generated, calculating the number of farts in a day is easier.  

How long does it take to fart we inhaled by another person? 

Fart spread depends on atmospheric factors such as humidity, temperature, wind speed and direction, wind is the molecular weight and the distance between producer and recipient. If not detected within a few seconds, it will be lost to the environment. But it is excepted if the departure is in a small enclosed space like an elevator, a car or small room. These sites prevent absorption into the environment and will remain bad for quite some time to be absorbed by the walls.

Do men fart more than women? 

No, women fart just as much as men. It's just that most men take more pride in it than most women. The number of individuals may be different farts, but it has nothing to do with gender. If a woman's lack of farts, meaning he is hard to keep wind and release the volume of gas per fart more.

Do men's farts smell worse than women's farts? 

Scientific studies of farts show that women’s darts have a higher concentration of odor-causing gases than men’s farts, but men’s farts have a larger volume. This will equalize the number of women that odor molecules are the same for both.

 Is it every people farts? 

Of course, if they're alive. People even fart shortly after death.  

Why do dog and cat farts smell so bad? 

A carnivore's protein-rich diet produces relatively small amounts of intensely stinky gas because proteins contain lots of sulfur. A dog's or cat's farts are rarely audible, but the odor is overwhelming. I have asked biologists why dogs and cats generally fart silently, and their theories include: 1. the amount of gas produced is small, but potent. 2.  the horizontal orientation of their gastrointestinal system puts less pressure on the anal opening, so the gas is expelled more slowly. 3.  their anal sphincters don't close as tightly as humans' because it takes less force to hold in the contents of the colon -- again because of the horizontal orientation of the gastrointestinal system -- and a loose anus makes less sound, and, my favorite. 4. dogs and cats don't feel embarrassed about farting, so their sphincters are more relaxed, leading to less noisy flatulence. If a cat farts audibly, it could be a sign of pathology. Large herbivorous animals such as cows, horses and elephants, on the other hand, produce vast quantities of relatively non-stinky fart gas. The farts of these animals are noisy and can go on for astoundingly long periods of time. Cows in particular are productive, in part because they swallow huge amounts of air. They need oxygen in their guts for the various protozoa employed there as digestive aids.
