The odor of farts comes from small amounts of hydrogen sulfide gas and
in the mixture. These compounds contain sulfur. Nitrogen-rich compounds
as skatole and indole also add to the stench of farts. The more
your diet, the more sulfides and mercaptans will be produced by the
in your guts, and the more your farts will stink. Foods such as
eggs and meat are notorious for producing smelly farts, whereas beans
large amounts of not particularly stinky farts.
Why are stinky farts generally
warmer and quieter than regular
Most fart gas comes from swallowed air and consists largely of nitrogen
carbon dioxide, the oxygen having been absorbed by the time it reaches
anal opening. These gases are odorless, although they often pick up
(and more odiferous) components on the way through the bowel. They
from the anus in fairly large bubbles at body temperature. A person can
achieve a good sound with these voluminous farts, but they are commonly
not always!) mundane with respect to odor, and don't feel particularly
Another major source of fart gas is bacterial action. Bacterial
and digestion processes produce heat as a byproduct as well as various
gases. The resulting bubbles of gas tend to be small, hot, and
with stinky bacterial metabolic products. These emerge as the
warm, SBD (Silent-But-Deadly), often in amounts too small to produce a
sound, but excelling in stench.
How much gas does a normal
person pass per day?
On average, a person produces about half a liter of fart gas per day,
over an average of about fourteen daily farts. Whereas it may be
for you to determine your daily flatus volume, you can certainly keep
of your daily numerical fart count. You might try this as a science
project: Keep a journal of everything you eat and a count of your
You might make a note of the potency of their odor as well. See if you
discover a relationship between what you eat, how much you fart, and
much they smell.
How long does it take fart
to travel to someone else's
Fart travel time depends on atmospheric conditions such as
and wind speed and direction, the molecular weight of the fart
and the distance between the fart transmitter and the fart receiver.

it will be too dilute for perception and will be lost into the
forever. Exceptional conditions exist when the fart is released into a
enclosed area such as an elevator, a small room, or a car. These
limit the amount of dilution possible, and the fart may remain in a
concentration for a long period of time, until it condenses on the

at the speed of sound, we would smell them almost instantly, at the
time we hear them.
Is it true that some people
No, not if they're alive. People even fart shortly after death.
Do men enjoy farts more?
Yes, most men take more pride in it than most women. There is a large
among individuals in the amount of fart gas produced per day, but the
does not correlate with gender. I have read that men fart more often
women. If this is true, then women must be saving it up and expelling
gas per fart than men do.
Do men's farts smell worse than
Based on what I have experienced of women's farts, all I can say is
that I hope not.
At what time of day is a
gentleman most likely to fart?
A gentleman is mostly likely to fart first thing in the morning, while
the bathroom. This is known as "morning thunder," and if the gentleman
good resonance, it can be heard throughout the household.
Why are beans so notorious for
making people fart?
Beans contain sugars that we humans cannot digest. When these sugars
our intestines, the bacteria go wild, have a big feast, and make lots
gas! Other notorious fart producing foods include corn, bell peppers,
milk, and raisins. A friend of mine had a dog who was exceptionally
of apples and turnips. The dog would eat these things and then get
gas. A dog's digestive system is not equipped to handle such vegetable
so the dog's bacteria worked overtime to produce remarkable flatulence.
What things other than diet can
make a person fart more than
People who swallow a lot of air fart more than people who don't. This
be cured somewhat by chewing with your mouth closed. Nervous people
fast moving bowels will fart more because less air is absorbed out of
intestines. Some disease conditions can cause excess flatulence. And
up in an airplane or other low-pressure environment can cause the gas
you to expand and emerge as flatulence.
Is a fart really just a burp
that comes out the wrong end?
No, a burp emerges from the stomach and has a different chemical
from a fart. Farts have less atmospheric gas content and more bacterial
content than burps.
Is it harmful to hold in farts?
There are differences in opinion on this one. Certainly, people have
for centuries that retaining flatulence is bad for the health. Emperor
even passed a law legalizing farting at banquets out of concern for
health. There was a widespread belief that a person could be poisoned
catch a disease by retaining farts. Doctors I have spoken to recently
told me that there is no particular harm in holding in farts. Farts
not poison you; they are a natural component of your intestinal
The worst thing that can happen is that you may get a stomach ache from
gas pressure. But one doctor suggested that pathological distention of
bowel could result if a person holds in farts too much.
How long would it be possible to
As I understand it, a captive fart can escape as soon as the person
This means that a lot of people who refrain from farting during the day
so at great length as soon as they fall asleep. Having been on a great
overnight field trips, long bus trips, and transpacific flights, I can
vouch for the fact that lots of people do fart voluminously as they
off. So the answer to the question would be, you can refrain from
as long as you can stay awake!
Do all people fart in their
I have not made a scientific study of this, but I don't think all
fart in their sleep. I think mainly those who refuse to fart when
awake do so when dozing off. For other people, toilet training takes
a strong hold that they let nothing pass their sphincters in sleep. For
people, the gas accumulates in the night and they vent it upon
Where do farts go when you hold
How often have you held in a fart, intending to release it at the first
opportunity, only to find that the fart has disappeared when you are
for it? I asked several doctors where the fart goes. Does it leak out
without the person knowing it? Is it absorbed into the bloodstream?

It simply migrates back upward into the intestine and comes out later.
is reassuring to know that such farts aren't really lost, just delayed.
How can one cover up a fart?
There is a company called Fartypants that sells underwear designed to
the odor of farts. If you should be caught without your Fartypants,
ploy is to blame the dog or cat, if one should be present, or complain
how the wind must be blowing from the direction of the paper mill. As

Other strategies include coughing or suddenly moving your chair so that
think that they misheard the fart. If you are with one other person,
can act as if nothing happened, and the other person may believe he was
in thinking he heard a fart. CJT addresses the problem of farting
in a public restroom as follows: "My solution: use a handful of loose
paper, cover your butthole and it will muffle the farting; my friends
I call it the 'Buff. Depending upon the company, another strategy is
to cover it up, but to proudly proclaim the fart as your own grand

Is it really possible to ignite
The answer to that is YES! (Armageddon,
Armageddon!) However, you
be aware that people get injured igniting flatulence. Not only can the

that about a quarter of the people who ignited their farts got burned

find it easier to accomplish the job using the Fartlighter. There have
been cases in which intestinal gases with a higher than normal oxygen
