Why Do We Scream "Geronimo" When Jumping From Things?

© Bettmann/CORBIS

??In the early 1940s, the United States Army was testing the idea of parachuting from planes as a way of deploying troops. The first group to really experiment with it and begin developing paratrooper techniques was a unit of 50 men known the Parachute Test Platoon.

These guys were based out of Fort Benning, Georgia, and spent most of their summer working through grueling training sessions in the afternoon heat, wearing parachutes on their backs along with the rest of their standard gear. When training was done for the day, the troops liked to loosen up and cool down a little. Usually, most of the guys went to the air-conditioned Main Post Theatre in the evenings to see whatever movie was playing.

One night in August 1940, that movie happened to be the Paramount western, Geronimo, about the Apache chief.

After the movie, there was beer. After beer, there was, as there often is, a boast. On their way back to their bunks after the film, the group got to talking about the jump they were doing the next day, their first as a group. The paratroopers only had a few solo jumps under their belts, and many of them were admittedly nervous. One of the guys, Private Aubrey Eberhardt, a brawny, six-foot-three native son of Georgia, claimed that he wasn’t worried. The mass jump would be nothing!

The other soldiers gave him a hard time. They were all scared. Of course he was scared, too. He should just admit it.

"All right, dammit!” Eberhardt finally shouted. “I’ll tell you jokers what I'm gonna do! To prove to you that I'm not scared out of my wits when I jump, I'm gonna yell ‘Geronimo’ loud as hell when I go out that door tomorrow!"

The next day, he made good on his promise. Out the plane he went and everyone heard “Geronimooooooo!” The rest of the platoon wasn’t about to let Eberhardt show them up, so on subsequent jumps the rest of the soldiers took up his battle cry and a tradition was born. The next year, the Army’s first official parachute unit, the 501st Parachute Infantry Battalion, made “Geronimo” the motto on their unit insignia after their commander tracked down descendants of the real Geronimo to ask for their permission to use his name.

After World War II, the army brass put an end to the mid-air yelling, worried that a screaming paratrooper would inevitably give away some unlucky unit’s position during operations. The heavy media coverage of the novel paratroopers during the war put the “Geronimo” cry in the public’s imagination, though, and Aubrey Eberhardt’s boozy brag lives on among civilians.

Big Questions
What Do Morticians Do With the Blood They Take Out of Dead Bodies?

Zoe-Anne Barcellos:

The blood goes down the sink drain, into the sewer system.

I am not a mortician, but I work for a medical examiner/coroner. During an autopsy, most blood is drained from the decedent. This is not on purpose, but a result of gravity. Later a mortician may or may not embalm, depending on the wishes of the family.

Autopsies are done on a table that has a drain at one end; this drain is placed over a sink—a regular sink, with a garbage disposal in it. The blood and bodily fluids just drain down the table, into the sink, and down the drain. This goes into the sewer, like every other sink and toilet, and (usually) goes to a water treatment plant.

You may be thinking that this is biohazardous waste and needs to be treated differently. [If] we can’t put oil, or chemicals (like formalin) down the drains due to regulations, why is blood not treated similarly? I would assume because it is effectively handled by the water treatment plants. If it wasn’t, I am sure the regulations would be changed.

Now any items that are soiled with blood—those cannot be thrown away in the regular trash. Most clothing worn by the decedent is either retained for evidence or released with the decedent to the funeral home—even if they were bloody.

But any gauze, medical tubing, papers, etc. that have blood or bodily fluids on them must be thrown away into a biohazardous trash. These are lined with bright red trash liners, and these are placed in a specially marked box and taped closed. These boxes are stacked up in the garage until they are picked up by a specialty garbage company. I am not sure, but I am pretty sure they are incinerated.

Additionally anything sharp or pointy—like needles, scalpels, etc.—must go into a rigid “sharps” container. When they are 2/3 full we just toss these into one of the biotrash containers.

The biotrash is treated differently, as, if it went to a landfill, then the blood (and therefore the bloodborne pathogens like Hepatitis and HIV) could be exposed to people or animals. Rain could wash it into untreated water systems.

Why Does Asparagus Make Your Pee Smell Funny?

The asparagus has a long and storied history. It was mentioned in the myths and the scholarly writings of ancient Greece, and its cultivation was the subject of a detailed lesson in Cato the Elder's treatise, On Agriculture. But it wasn't until the turn of the 18th century that discussion of the link between asparagus and odorous urine emerged. In 1731, John Arbuthnot, physician to Queen Anne, noted in a book about food that asparagus "affects the urine with a foetid smell ... and therefore have been suspected by some physicians as not friendly to the kidneys." Benjamin Franklin also noticed that eating asparagus "shall give our urine a disagreeable odor."

Since then, there has been debate over what is responsible for the stinky pee phenomenon. Polish chemist and doctor Marceli Nencki identified a compound called methanethiol as the cause in 1891, after a study that involved four men eating about three and a half pounds of asparagus apiece. In 1975, Robert H. White, a chemist at the University of California at San Diego, used gas chromatography to pin down several compounds known as S-methyl thioesters as the culprits. Other researchers have blamed various "sulfur-containing compounds" and, simply, "metabolites."

More recently, a study demonstrated that asparagusic acid taken orally by subjects known to produce stinky asparagus pee produced odorous urine, which contained the same volatile compounds found in their asparagus-induced odorous urine. Other subjects, who normally didn't experience asparagus-induced odorous urine, likewise were spared stinky pee after taking asparagusic acid.

The researchers concluded that asparagusic acid and its derivatives are the precursors of urinary odor (compared, in different scientific papers, to the smell of "rotten cabbage," "boiling cabbage" and "vegetable soup"). The various compounds that contribute to the distinct smell—and were sometimes blamed as the sole cause in the past—are metabolized from asparagusic acid.

Exactly how these compounds are produced as we digest asparagus remains unclear, so let's turn to an equally compelling, but more answerable question:

WHY DOESN'T ASPARAGUS MAKE YOUR PEE SMELL FUNNY?

Remember when I said that some people don't produce stinky asparagus pee? Several studies have shown that only some of us experience stinky pee (ranging from 20 to 40 percent of the subjects taking part in the study, depending on which paper you read), while the majority have never had the pleasure.

For a while, the world was divided into those whose pee stank after eating asparagus and those whose didn't. Then in 1980, a study complicated matters: Subjects whose pee stank sniffed the urine of subjects whose pee didn't. Guess what? The pee stank. It turns out we're not only divided by the ability to produce odorous asparagus pee, but the ability to smell it.

An anosmia—an inability to perceive a smell—keeps certain people from smelling the compounds that make up even the most offensive asparagus pee, and like the stinky pee non-producers, they're in the majority.

Producing and perceiving asparagus pee don't go hand-in-hand, either. The 1980 study found that some people who don't produce stinky pee could detect the rotten cabbage smell in another person's urine. On the flip side, some stink producers aren't able to pick up the scent in their own urine or the urine of others.
