National Pass Gas Day

Passing gas—everyone does it. The technical term for the gas that builds up is flatus, and when someone passes it out of their body we say they have flatulence. That's a nice way of putting it—most people just call it farting. The word "fart" was thought up in 1632; it means "to send forth wind from the anus," and comes from the Old English word "feortan," which means "to break wind." Farts can travel at speeds of about 10 feet per second, almost 7 miles per hour. On average, people fart about 14 times a day, producing enough gas to fill up a balloon. This means everyone should have multiple opportunities to fully celebrate National Pass Gas Day today.

It is fitting that yesterday was Bean Day, because people often fart after eating beans. Other foods that are flatulence enablers include cabbage, broccoli, cauliflower, brussels sprouts, eggs, and dairy products. Pressure builds up while foods such as these are broken down and digested in the colon, and it is released by passing gas.

A mixture of gases make up farts, such as nitrogen, oxygen, carbon dioxide, hydrogen, sulfur dioxide, and methane. About 99% of gas is odorless, but it is the other 1% that can really stink up a room. The smelly component of farts is usually sulfurous. Common gases that give it its smell include dimethyl sulfide, methanethiol, and hydrogen sulfide. Foods like eggs and meat have a higher sulfur content and help produce smellier farts.

The methane and hydrogen in farts also makes them flammable. This may not sound like that big of a deal, but there are examples of cows farting themselves into flames. That's right, animals fart too. And the belief that women fart less than men? It just isn't true. Fart sounds vary and depend on how much gas is released, the force at which it comes out, and the tightness of one's sphincter muscles. People who have tight anuses have louder farts.

Farts have been looked on as being humorous for millennia. The earliest recorded fart joke dates to 1900 BCE in Sumeria, when a jokester said, "Something which has never occurred since time immemorial; a young woman did not fart in her husband's lap." Fart jokes have continued into modern times, often being included in stand-up comedy routines and movies. Whoopie cushions have also been used to joke about flatulence.

Flatulists are those who fart for a living. Le Pétomane, whose name meant "fartomaniac," was a prominent flatulist in France during the late nineteenth and early twentieth century. More recently, Mr. Methane has been bringing his farting talent to the stage, even appearing on Britain's Got Talent. Farts have not only been performed on the stage, but have appeared in the writings of Shakespeare, Chaucer, and Dante. Benjamin Franklin even wrote an essay titled "Fart Proudly."
