Why is the Drinking Age 21?

In short, we ended up with a national minimum age of 21 because of the National Minimum Drinking Age Act of 1984. This law basically told states that they had to enact a minimum drinking age of 21 or lose up to 10 percent of their federal highway funding. Since that's some serious coin, the states fell into line fairly quickly. Interestingly, this law doesn't prohibit drinking per se; it merely cajoles states to outlaw purchase and public possession by people under 21. Exceptions include possession (and presumably drinking) for religious practices, while in the company of parents, spouses, or guardians who are over 21, medical uses, and during the course of legal employment.

That answers the legal question of why the drinking age is 21, but what was the underlying logic of the original policy? Did lawmakers just pick 21 out of a hat because they wanted college seniors to learn the nuances of bar culture before graduation? Not quite. The concept that a person becomes a full adult at age 21 dates back centuries in English common law; 21 was the age at which a person could, among other things, vote and become a knight. Since a person was an official adult at age 21, it seemed to make sense that they could drink then, too.

WHO WAS RESPONSIBLE FOR LOWERING THE DRINKING AGE TO 18 FOR PART OF THE 20TH CENTURY, THOUGH?

Believe it or not, Franklin Roosevelt helped prompt the change in a rather circuitous fashion. FDR approved lowering the minimum age for the military draft from 21 to 18 during World War II. When the Vietnam-era draft rolled around, though, people were understandably a bit peeved that 18-year-old men were mature enough to fight, but not old enough to vote. Thus, in 1971 the states ratified the 26th Amendment, which lowered the voting age to 18. Legislators started applying the same logic to drinking. The drinking age, which the 21st Amendment made the responsibility of individual states, started dropping around the country.

Critics of the change decried rises in alcohol-related traffic fatalities among 18- to 20-year-old drivers in areas where the drinking age had been lowered. Indeed, one result of leaving states in charge of their own age was the creation of "blood borders" between states that allowed 18-year-olds to drink and those that didn't. Teenagers from the more restrictive state would drive into the one where they could buy booze, drink, and then drive home, which created a perfect storm for traffic fatalities. Even if teens weren't any more predisposed than older adults to drive after they'd been drinking, all of this state-hopping meant that those who did drive drunk had to drive greater distances to get home than their older brethren, who could just slip down the block for a beer or six. More miles logged in a car meant more opportunities for a drunken accident.

WHO LED THE BACK-TO-21 MOVEMENT?

Organizations like Mothers Against Drunk Driving began agitating for a uniform national drinking age of 21 to help eliminate these blood borders and keep alcohol out of the hands of supposedly less-mature 18-year-olds. As a result, President Reagan signed the aforementioned National Minimum Drinking Age Act of 1984. MADD's "Why 21?" website touts that, "More than 25,000 lives have been saved in the U.S. thanks to the 21 Minimum Legal Drinking Age." Traffic reports show a 61 percent decrease in alcohol-related fatalities among drivers under 21 between 1982 and 1998. Raw numbers show that drunk driving fatalities have definitely dropped since the early 1980s; since 1982, drunk driving fatalities have decreased 51 percent. Among drivers under 21, drunk driving-related deaths have decreased by 80 percent.

Teasing out the underlying cause of this reduction in total fatalities is no mean feat, though. Non-alcohol traffic fatalities have also declined relative to the number of miles driven over the same time period, which could be attributed to any number of causes, including increased seat belt usage, the widespread use of airbags, and other safety improvements to cars and roads. Moreover, drinking and driving for the whole population might be down as the result of increased education on its consequences, harsher penalties, improved enforcement, or increased stigmatization of drunk driving.

College presidents who supported the Amethyst Initiative—a movement launched in 2008 to reconsider the national drinking age of 21—admit that drunk driving is a serious problem, but they point out that it's not the only potential pitfall for young drinkers. They contend that by lowering the drinking age, colleges would be able to bring booze out into the open and educate students on responsible consumption. Such education might help curb alcohol poisoning, drunken injuries, drinking-fueled violence, and alcoholism on campuses.

Interesting bit of trivia: the group takes its name from the character Amethyst in Greek mythology. She ran afoul of a drunken Dionysus, who had her turned into white stone. When the god discovered what he'd done, he poured wine on the stone, turning it into the purple rock we know as amethyst. Ancient Greeks wore the mineral as a form of protection from drunkenness.

What Happens When You Flush an Airplane Toilet?

For millions of people, summer means an opportunity to hop on a plane and experience new and exciting sights, cultures, and food. It also means getting packed into a giant commercial aircraft and then wondering if you can make it to your next layover without submitting to the anxiety of using the onboard bathroom.

Roughly the size of an apartment pantry, these narrow facilities barely accommodate your outstretched knees; turbulence can make expelling waste a harrowing nightmare. Once you’ve successfully managed to complete the task and flush, what happens next?

Unlike our home toilets, planes can’t rely on water tanks to create passive suction to draw waste from the bowl. In addition to the expense of hauling hundreds of gallons of water, it’s impractical to leave standing water in an environment that shakes its contents like a snow globe. Originally, planes used an electronic pump system that moved waste along with a deodorizing liquid called Anotec. That method worked, but carrying the Anotec was undesirable for the same reasons as storing water: It raised fuel costs and added weight to the aircraft that could have been allocated for passengers. (Not surprisingly, airlines prefer to transport paying customers over blobs of poop.)

Beginning in the 1980s, planes used a pneumatic vacuum to suck liquids and solids down and away from the fixture. Once you hit the flush button, a valve at the bottom of the toilet opens, allowing the vacuum to siphon the contents out. (A nonstick coating similar to Teflon reduces the odds of any residue.) It travels to a storage tank near the back of the plane at high speeds, ready for ground crews to drain it once the airplane lands. The tank is then flushed out using a disinfectant.

If you’re also curious about timing your bathroom visit to avoid people waiting in line while you void, flight attendants say the best time to go is right after the captain turns off the seat belt sign and before drink service begins.

Why is Friday the 13th Considered Unlucky?

Today, people around the globe will feel uneasy about getting out of bed, leaving their homes, or going about their normal daily routines, all because of a superstition. These unfortunate folks suffer from paraskavedekatriaphobia, a common neurosis familiar to us all: the fear of Friday the 13th. But just where did this superstitious association come from, and how did it catch on?

The truth is that no one is absolutely sure where the idea that Friday the 13th is unlucky originated. Donald Dossey, the founder of the Stress Management Center and Phobia Institute in Asheville, North Carolina, suspects the fear can be traced back to a Norse myth about 12 gods who had a dinner at Valhalla—the fabled hall where legendary Norse heroes feasted for eternity after they died—that was interrupted by a 13th guest, the evil and mischievous god Loki.

According to legend, Loki tricked Höðr (the blind god of winter and son of Odin, the supreme god in Norse mythology) into shooting his brother Baldr (the benevolent god of summer who was also a son of Odin) with a magical spear tipped with mistletoe—the only substance that could defeat him. Thus the number 13 was branded as unlucky because of the ominous period of mourning following the loss of such powerful gods by this unwanted 13th guest.

For whatever reason, among many cultures, the number 12 emerged throughout history as a "complete" number: There are 12 months in a year, 12 signs of the zodiac, 12 Gods of Olympus, 12 sons of Odin, 12 labors of Hercules, 12 Jyotirlingas or Hindu shrines where Shiva is worshipped, 12 successors of Muhammad in Shia Islam, and 12 tribes of Israel. In Christianity, Jesus was betrayed by one of his 12 Apostles—Judas—who was the 13th guest to arrive for the Last Supper. Surpassing the number 12 ostensibly unbalances the ideal nature of things; because it is seen as irregular and disrespectful of a sense of perfection, the number 13 bears the stigma of misfortune and bad luck we know today.

WHY FRIDAY?

Friday joins in the mix mostly because all of the early accounts of Jesus’s crucifixion agree that it took place on Friday—the standard day for crucifixions in Rome. As Chaucer noted in The Canterbury Tales, "And on a Friday fell all this mischance." Yet perpetuating Friday as an unlucky day in America came from the late 19th-century American tradition of holding all executions on Fridays; Friday the 13th became the unluckiest of days simply because it combined two distinct superstitions into one. According to the Oxford University Press Dictionary of Superstitions, the first reference to Friday the 13th itself wasn’t until 1913. (So despite actually occurring on Friday, October 13, 1307, the popular notion that the Friday the 13th stigma comes from the date on which the famed order of the Knights Templar were wiped out by King Philip of France is just a coincidence.)

The repercussions of these phobias reverberated through American culture, particularly in the 20th century. Most skyscrapers and hotels lack a 13th floor, which specifically comes from the tendency in the early 1900s for buildings in New York City to omit the unlucky number (though the Empire State Building has a 13th floor). Some street addresses also skip from 12 to 14, while airports may skip the 13th gate. Allegedly, the popular Friday the 13th films were so-named just to cash in on this menacing date recognition, not because the filmmakers actually believed the date to be unlucky.

So, is Friday the 13th actually unlucky? Despite centuries of superstitious behavior, it largely seems like psychological mumbo jumbo. One 1993 study seemed to reveal that, statistically speaking, Friday the 13th is unlucky, but the study's authors told LiveScience that though the data was accurate, "the paper was just a bit of fun and not to be taken seriously." Other studies have shown no correlation between things like increased accidents or injuries and Friday the 13th.

And Friday the 13th isn't a big deal in other cultures, which have their own unlucky days: Greeks and Spanish-speaking countries consider Tuesday the 13th to be the unluckiest day, while Italians steer clear of Friday the 17th. So today, try to rest a little easy—Friday the 13th may not be so unlucky after all.
