Why Do Olympians Wear That Colorful Tape?

You may have first noticed the markings on the synchronized swimmers' backs. Or cascading down a beach volleyball player's chiseled abs. Birthmarks? Accessories? A bizarre form of intimidation? No, no, and no. The answer is Kinesio tape. And, yes, it's all the rage in the sports world.

So, what is this tricked-out injury treatment?

It's a heavily adhesive, hypoallergenic, stretchy tape that comes, as we have seen, in an array of colors and patterns. It is designed to approximate the weight and thickness of skin and can be stretched over any part of the body. Made of cotton fiber, the tape has an acrylic, heat-activated backing and can stay attached for up to five days. When adhered, the tape lifts the upper layers of the skin away from the muscle, relieving pressure and pain in the affected area.

While the tape was developed by Dr. Kenzo Kase in the mid-1970s, it first started cropping up on a body part here or there during the Beijing Olympics in 2008. But that was enough to spark an interest and, following the summer games, sales of the tape jumped a reported 300 percent. Now, clearly, it has taken the athletic world by storm.

But if you, lay-athletic person, were hoping to jump on the Kinesio bandwagon, you may have to sit tight, because not just anyone can slap on the tape. To do it properly, you need to use a particular technique that requires training.

DOES IT WORK?

The research is slim, and some scientists are dubious. According to Reuters, a 2012 report in the journal Sports Medicine found "little quality evidence to support the use of Kinesio tape over other types of elastic taping in the management or prevention of sports injuries." But Kevin Anderson, director of Kinesio UK, says the research just needs time to catch up to the sports phenomenon.

"There's nothing magical in the tape," Anderson told Reuters, "it certainly can't improve your performance or make you Superman," but he says it does help relieve pain and swelling for the athletes.

German beach volleyball player Sara Goller, who wore hot pink tape throughout the 2012 London Games, says the color is nice, but its purpose is what matters. "It can release or put tension on a muscle, it depends on what you want," she told Reuters.

Lindon, Utah-based brand KT Tape is the official Kinesiology tape licensee of the U.S. Olympic team and counts Kerri Walsh Jennings, James Harden, and Kerri Strug among its fans.

Even if the tape doesn't actually do anything beneficial, physically, it can give athletes a boost of confidence, simply because they think it is working wonders on their battered bodies. And in such high-stakes, high-pressure situations like the Olympic Games, the slightest form of encouragement is sometimes all you need.

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.
