Facts:
The average number of gas passages is 13 ± 4 in one day
Most of us pass somewhere between 200 and 2,000 ml of gas per day (average, about 600 ml)
Farts are composed of: nitrogen (N2), oxygen (O2), carbon dioxide (CO2), hydrogen (H2), and methane (CH4)
Despite the flammable nature of flatal H2 and CH4, no hazard is likely to those working near open flames
Gas gets into our guts by air swallowing (which accounts for very little), production within the bowel and colon (which accounts for a lot), and diffusion from the blood

What makes farts stink?
The odor of farts comes from small amounts of hydrogen sulfide gas and mercaptans in the mixture. These compounds contain sulfur. Nitrogen-rich compounds such as skatole and indole also add to the stench of farts. The more sulfur-rich your diet, the more sulfides and mercaptans will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts.
Why do farts make noise?
The sounds are produced by vibrations of the anal opening. Sounds depend on the velocity of expulsion of the gas and the tightness of the sphincter muscles of the anus. Contrary to a popular misconception, fart noise is not generated by the flapping of the butt cheeks.
SBD (Silent-But-Deadly)
A 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.
Why is there a 13 to 20 second delay between farting and the time it starts to smell?
Actually, the fart stinks immediately upon emergence, but it takes several seconds for the odor to travel to the farter's nostrils. If farts could travel at the speed of sound, we would smell them almost instantly, at the same time we hear them.
Is it true that some people never fart?
No, not if they're alive. People even fart shortly after death.
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.
Do men's farts smell worse than women's farts?
All I can say is that I hope not. Scientific studies of farts show that women's farts have a higher concentration of odor-causing gases than men's farts, but men's farts have a larger volume. The two factors equalize out (the same number of stench molecules for both), so the odor is about the same.
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 in the bathroom. This is known as "morning thunder," and if the gentleman gets good resonance, it can be heard throughout the household.
Is it possible to leave a brown spot on your pants because of a fart, and if so, what causes it?
I'd say that the answer to the first question is definitely yes.
As for the causes, we must remember that what we call "fart" and what we call "poop" are just end-members of a continuum. That is, we can have a pure fart, or a pure poop, or anything in-between, depending upon the admixture of the two.
If a sample consists mostly of poop with only a small fart component, you get such things as jet-propelled bowel movements and spongy, floating fecal masses (you know, the ones that refuse to be flushed down the toilet -- they keep popping back up).
If the sample consists mostly of fart with only a small poop component, you get what is known as "skid marks" or "fart art." These can also result from inadequate wiping, but the shape of the stain is different in the two cases. Inadequate wiping leads to elongate marks parallel to one's crack, usually with well-defined edges, whereas fart art is generally more circular and has an air-brushed look.
Fart art is most likely to occur if (1) a person is suffering from diarrhea, (2) the person is trying too hard to fart, and (3) the person mistakenly perceives the pressure against his sphincter to be gas pressure rather than liquid pressure. Again, that last situation is most likely to occur if the person is afflicted with diarrhea.
Can excessive farting cause impotence?
That depends on the tolerance level of the person with whom one is trying to be potent!
Fortunately for humans, farting doesn't cause tissue damage. Other animals aren't so lucky. Soldier termites can actually turn themselves into bombs by detonating themselves via the explosive release of gas and feces, a process called "autothysis."
If you were in space without a suit, would a fart have the energy to propel you forward?
Yes, a fart should propel you forward, since there is virtually no opposing force in the form of friction or gravity to counteract the force of the fart.
