Last week when I wrote about the guy who turned blue, I knew there were two reasons for people to turn blue, but I couldn't recall what the other one (besides colloidal silver) was. Now I remember! It's methemoglobinemia. I've even written about it. What does that have to do with Tylenol? You'll have to watch the video to find out. 
  
Tylenol has been sold since 1955, but its history goes back much further. The underlying medicine's fever-reducing talent was discovered purely by accident, and I mean an accident at a pharmacy that could have been much, much worse. But it worked, not only to reduce fever, but to squelch pain as well. Testing has deemed it safe and effective, but scientists still don't know the exact mechanism of that effectiveness. It's possible that we might never know, because there are much more important problems than the exact mechanism of a drug that's already safe and effective. This video from Half as Interesting is a minute shorter than it looks, because that last part is an ad.    

     

When we think about an uprising of the common people against ruthless overseers, we think of the French Revolution or maybe the Haitian Revolution, but one story from medieval Spain illustrates the concept well, whether it's true or not. And it all started over a single fish. 

In 1158, in the town of Zamora on the border between the kingdoms of León and al-Andalus, a marketplace dispute began. A shoemaker bought the last trout of a fishmonger, when a servant of the local ruling knight Gómez Álvarez showed up and demanded the fish for his lord. A dispute ensued, and other townspeople joined in both sides. The servant left without the fish, and Álvarez was angry that the peasants didn't know their place. He gathered other knights together with the idea that such resistance cannot stand because it would undermine their authority. Meanwhile, the townspeople who supported the shoemaker gathered to  burn down the church where the knights were meeting. The battle eventually escalated to the King of León. Some doubt the details, or if it ever even happened, but it's a great story you can read at Amusing Planet.

The board game Monopoly was invented by Lizzie Magie in 1904. She called it The Landlord's Game, and it was designed to illustrate the evils of capitalism. Charles Darrow stole the idea and made Monopoly to appeal to a player's greed, and that's when it took off. The game has been teaching children how to be ruthless ever since. 

But people don't read the rules of the game anymore. They are long and involved and the print is too small. People tend to just play Monopoly the way they were taught, forgetting half of it, and many of the original rules have fallen by the wayside. Simon Whistler explains some of the most common Monopoly rules that are altered or ignored in the 21st century, and how the way most folks play it these days slows the game down and makes it more boring. It's still pretty ruthless, though. Your children will learn better things by playing Scrabble, or even Candyland.

People who are born blind and have their sight restored at a later age tend to not look at people's faces when they speak to them- they instead look at their hands. That's because they have built their sensory world around touch, hearing, and other senses and have more experience with someone else's hands than with faces. But that's only one way newly-sighted people have to learn how to deal with a world they can suddenly see. 

Children born with cataracts can be treated surgically, but in developing countries this treatment may be out of reach. This gives us a population of people to study who have their sight restored after they have learned to live as a blind person. Their brains have to adjust to perceive the signals that an infant learns naturally over time, like separating shapes from colors, depth perception, distinguishing outlines, and facial recognition. During blindness, the visual cortex is often rerouted to process non-visual signals. Still, the brain is very adaptable. Read about the way people see for the first time at Big Think.

I had to look up a lot of terms to understand this video, but you don't really have to understand it to be impressed. The sarabande is a dance that dates back about 500 years that is notable for being three times as fast as a normal dance. Sarabande 2X Co-Op is a very difficult video game that uses a sarabande song at 157 beats per minute. It's played on the Pump It Up arcade game console that you play with your feet, like Dance Dance Revolution, except there are five foot pads, or ten if you play with a partner. Got all that? 

Gamers ElijahTS and Tomatonium recently became the first team ever to finish this truly difficult game with a perfect score, during a livestream with plenty of witnesses. This is not just watching two guys play a video game; this is serious fancy footwork. They don't really get going until about 50 seconds into the video, and by then you'll be glad you stuck with it. -via Born in Space 

Disney animated movies are not all sweetness and light. A good drama tugs at your heartstrings, and Disney has perfected the art of building up your hopes and dreams by making you care about the characters, and then yanking them away in a minute. A consulting firm called sheets.works crunched the numbers and found that the moment of heartbreak most often comes halfway through a Disney film, although they vary from five minutes in (Encanto) to 96% of the way through the story (Pocahontas). Almost half involve the death of a parent. 

They have a chart listing 33 Disney animated films, ranked by where the heartbreak comes in. Click the movie title to bring up the moment and its statistics, such as its type and how devastating it is. If you've seen the movies, it will take you back to how you felt watching it for the first time. -via Metafilter 

A superhero's costume must be skin tight, colorful, and come with a cape. But superhero costume designer Edna Mode says, "No capes!" and therefore some of the more modern superheroes don't. So why do the old school heroes like Superman and Batman wear capes? It's not just because capes are cool. 

To get the real story, we have to go back to the pop culture that inspired the comic book superhero in the first place, back in the 1930s. Once a character has been designed, artists found all kinds of ways to use the cape to illustrate different aspects of the character or the story. As more and more superheroes came about, some went without capes just to be different, or as a statement that they aren't a slave to obsolete fashion unless the character was designed to be old-fashioned. My mother made a red cape and a blue cape for my brother and me to play superhero with. Whoever had the red cape was Superman, and the other was Batman. I made capes for my kids, too. When you have a cape, you don't need a full costume to be a superhero. -via Laughing Squid 

On March 16, 1926, Robert H. Goddard launched the first liquid-fueled rocket in Massachusetts. It was a small rocket that flew for a short time and crash-landed, but it reached a height of 184 feet. Forty-three years later, another rocket of its kind would take men to the moon. 

Still, the American investment in rocket technology was slow. The Germans used V2 missiles in warfare during World War II, and the scientists who developed it came to the US after the war. Still, American investment was slow in the next years. But then, the USSR launched a satellite in 1957, and America was thrust into a competition for space. Millions of dollars were poured into the new agency called NASA with the goal of outdoing the Soviets. That battle was won when Neil Armstrong walked on the moon in 1969. Since then, NASA's budget has waxed and waned, through joint operations with the Soviets and then the Russians, satellites, long-range unmanned probes, the space shuttle, and various space stations. Now that rocketry has fallen into the hands of private companies, it's time to look back at how far the technology has come in 100 years. Read a timeline of rocket history at the Conversation. 

Michael Jackson is second on the list of the most successful recording artists in history, behind only The Beatles -whose music Jackson bought in 1985. That musical legacy was tarnished by the very weirdness of his personal life. Whether he was nefarious or just plain eccentric, he knew how to make headlines. But you might not know what came before. Yeah, that was the Jackson 5, which was the product of Joe Jackson. 

While Joe chased fame all his life without success, it was always just outside his grasp. But Jackson's father saw his musically-talented young sons as a ticket to the big time, which must be cultivated by any means necessary. The cost was enormous for all his nine children, but especially for Michael. Michael spent his adult life rebuilding a fantasy childhood to make up for the normal one he never got. Weird History looks back in time to the Jackson family and their ascent to fame.

When a franchise has been running for 49 years, the kids who were fans from the start grow up, and some of them end up with enough clout to talk themselves into being in another movie. Casting a Star Wars film is a big job, but celebrity volunteers for the small roles and the extras just come out of the woodwork. It's as easy as "This is (someone already famous). Can I be in your movie?" Sure thing! Put a movie star into a stormtrooper helmet, and you don't have to give them screen credit. Some of these stars are such avid fans that you wouldn't even have to pay them, but that's probably against union rules. In some cases, you don't even have to be a movie star, if the crew already knows you. 

Read up on 15 of the unlikely cameos and extras that celebrities talked Star Wars producers into at Cracked. 

We've heard plenty of stories about offices, stores, and other work places that adopted a cat or a dog, but this tale is a bit more offbeat. A hen wandered into the Public Works department in Truman, Minnesota, about a year ago, and never left! Employees said she was pretty bedraggled, and they suspect she had been chased there by a dog. But no one in the area seems to have lost a chicken, or at least they didn't claim her. That's understandable. I asked a friend how many chickens she had, and she couldn't say because they won't stand still long enough to be counted. 

Anyway, this chicken decided that the city facility was now her home, and they named her Noodles. She is well loved and fed. Noodles spends her days supervising the staff from a high perch and her nights laying eggs for the utility workers, and they couldn't be happier about it. 

The common brushtail possum is native to Australia, but is an invasive species in New Zealand, where they threaten both agriculture and native bird species. Trapping or poisoning possums is a problem because some are too smart or too shy to approach traps. Wildlife biologist Graham Hickling needed an irresistible bait to lure possums to the traps. He discovered the Selena Gomez limited edition Oreo cookies, which have a layer of cinnamon between the chocolate wafers. Hickling found that Oreos are easy to use, because you can drill a hole in the middle and affix them with a nail, much better than Tim Tams. 

"Oreos are quite a bit cheaper, and they actually stand up to the rain quite well too, which is a little disconcerting.”

Possums found the combination of cinnamon and chocolate irresistible. Traps without the Oreos caught one possum in nine days, while the "Selena Gomez regime" traps caught 15 possums in 20 days. Read how this success came about at the Spinoff.  -via Nag on the Lake 

When you can choose your own name for the internet, the temptation can be overwhelming. Many people learned their lesson years ago about the names they chose for an email address in the 9th grade when they later had to use those addresses to apply for jobs. But usernames for specific platforms are still fair game, and gamertags are part of the creative process in customizing your character. Who's going to care if you sign up as "Poopyfartybum69" to play your favorite online multiplayer fantasy adventure game? The poor NPC who has to introduce you, that's who.

In this video from Viva La Dirt League, the usernames get worse and worse as it goes along. Some are even too salacious for YouTube. You have to admire the stoicism of the actors, because this is just too close to a certain Monty Python routine that we are all familiar with. -via Geeks Are Sexy 

At 42, with three young kids, I got a diagnosis that would have me dead in a year. That was, somehow, just the beginning. https://t.co/KWx2pdbiWo

Longtime Neatorama readers might remember Christopher Ingraham, who crunched the numbers to rank all the US counties by scenery and climate and found that Red Lake County in Minnesota was the worst of them. The reason you might remember that is because Red Lake County invited Ingraham to visit, and the people were so friendly and he liked it so much that he moved his family there in 2016. 

What's happened since then? In 2022, Ingraham received a diagnosis of cholangiocarcinoma, or cancer of the bile duct. This cancer has a survival rate of about 10%, with most patients dying within a year. He was only 42. The best treatment is get a liver transplant, if you are medically eligible. Ingraham has written about the ordeal of facing death at a young age with three young children for Slate. Here is an alternate link. There are two surprises at the end. -via Metafilter 

You've probably noticed that the hair on your head grows a lot longer than the hair on, let's say, other parts of your body. Hair follicles each have their own terminal length, meaning how much time they spend on growing a hair, and how fast, before they give up and let the hair fall out. And then that follicle will start over again, or maybe not. The hair follicles on your body come in different types with different programming, and those on your head are the most productive, up to a point. Believe it or not, these follicles can be transplanted to a different body part! 

But everyone's follicles are different. Some women never cut their hair, and they still have different lengths because their hair follicles are programmed differently. This TED-Ed lesson from Maksim Plikus explains what's going on inside those follicles to give you the hair you have. -via Damn Interesting
