WTF Fun Fact 12725 – Ancient Stone Pillows

It’s hard to find a good pillow. And while some of us like our pillow firm, it would take a major adjustment to sleep like ancient Mesopotamians and Egyptians (well, in more ways than one, I suppose).

Here’s one of the most famous pillows in history, brought to you from Egypt King Tut’s tomb:

One of 8 headrests found in Tutankhamun’s tomb. The god of air, Shu, is carved in ivory. The piece resides in the Egyptian Museum in Cairo.

It’s beautiful, but it lacks the kind of functionality we typically look for today.

Until the Industrial Revolution, pillows weren’t even a household object. Yes, some ancient Greeks and Romans did stuff straw in cloth to lay their heads on, but a pillow is also a symbol of having excess lying around to use for more practical purposes. However, we can credit the Greeks with bringing us closer to the era of the soft pillow.

However, in ancient Mesopotamia, China, and Egypt, wealthy people would elevate their heads on “pillow” made of stone (or ivory – or another luxury material). They were designed to keep insects out of their ears, noses, and mouths – and probably to maintain a good hairstyle every now and then.

We’ve also found some pillows that are beautifully engraved with messages about keeping away bad spirits as well, but it’s unclear how those would be fooled by an elevated head. Still, it gives us a good idea of what ancient people were concerned about when they laid down their heads at night. — WTF fun facts

WTF Fun Fact 12724 – Creating Summer Indoor Entertainment

Without Willis Carrier’s 1902 invention of the air conditioner, we’d have a very different world. And it would have started with missing out on opportunities for indoor cultural experiences in the summer when people are most commonly off from work and school.

Carrier’s original design was meant for a publishing company in Brooklyn that needed to keep its paper from expanding and contracting so it could achieve proper print quality while it was hot and humid. But not long after that, businessmen saw the opportunities to add it to factories (which technically cut off some summer break for workers who could now work more safely in the summer) and then to department stores. The real cultural moment came when it was added to movie theaters in the mid to late 1920s and regular theaters in the 1960s.

For example, Carrier’s company put an air conditioner in Lincoln Center in 1961. This extended the performing arts season in New York City from “a single season to 52 weeks a year,” according to the Carrier website.

WTF Fun Fact 12723 – Air Conditioning Was Invented In Buffalo, New York

Willis Carrier is the man to thank if you’re cooling off in an air-conditioned space today. He was born in Angola, New York, and attended high school in Buffalo, where he would later work, he submitted the first drawings for a cooling unit in 1902.

Children and some laborers were already some time off in the summer when productivity was low because of heat and humidity. But, of course, many companies needed to keep on producing their goods.

Carrier, who got an engineering degree at Cornell and then returned to work as a research engineer at Buffalo Forge Company, was set upon the task.

But the primary goal wasn’t to give us all comfort during sweltering summers. In fact, according to the Willis Carrier website, the “young research engineer initialed a set of mechanical drawings designed to solve a production problem at the Sackett & Wilhelms Lithography and Printing Company in Brooklyn, New York.” Ironically, it was a problem with paper.

Also interesting is that Buffalo Forge was a supplier of forges, fans, and hot blast heaters. Creating cold air is the first challenge that needed addressing!

So why begin with paper? Why does paper need to be cool?

Well, it turns out it expands and contracts when heat and humidity are a problem – and that’s just not good when you need to print something.

Again, according to the website that now carries his life story:

“In the spring of 1902, consulting engineer Walter Timmis visited the Manhattan office of J. Irvine Lyle, the head of Buffalo Forge’s sales activities in New York. Timmis’ client, Sackett & Wilhelms, found that humidity at its Brooklyn plant wreaked havoc with the color register of its fine, multicolor printing. Ink, applied one color at a time, would misalign with the expansion and contraction of the paper stock. This caused poor quality, scrap waste and lost production days, Timmis said. Judge magazine happened to be one of the important clients whose production schedule was at risk. Timmis had some ideas about how to approach the problem but would need help. Was Buffalo Forge interested?”

Carrier was tasked with the problem because he already had a sterling reputation as a researcher and data collector, and this problem would need a lot of work.

But he did it. He was able to not only produce cool air but humidity as well by “replacing steam with cold water flowing through heating coils, balancing the temperature of the coil surface with the rate of air flow to pull the air temperature down to the desired dew point temperature.”

It wasn’t perfect, but it did the job. Carrier later started a company, and sold his updated creations to factories, and then to department stores and movie theaters in the 1920s.

WTF Fun Facts 12723 – No Such Thing As A “Safe Tan”

It’s been decades since we’ve known that tanning beds cause cancer and yet some folks just can’t get enough. It doesn’t help that the tanning industry continues to tout the benefits despite copious scientific evidence that they’re unsafe at best (and, at worst, deadly).

Of course, sun exposure is damaging too, but some of us can’t avoid that – you actually have to walk in and pay for skin damage at a tanning salon dispute there being no physiological benefit (for example, there’s no such thing as a “healthy base tan”).

In addition, a study published in JAMA Internal Medicine estimated that more than 3,200 people are treated for tanning-related injuries in US emergency rooms every year.

It’s hard to hear for many people as “tanning addition” becomes more of a problem, especially among young, white women.

But here are just a few facts from the American Academy of Dermatology Association to provide food for thought:

  • Even one indoor tanning session can increase the risk of developing skin cancer (melanoma by 20%, squamous cell carcinoma by 67%, and basal cell carcinoma by 29%).
  • Nearly 25% of young adults the Academy surveyed were unaware or unsure that tanning beds are not safer than the sun.
  • You can’t get enough vitamin D from tanning beds because the bulbs used emit mostly UVA light; however, your body needs UVB light to make vitamin D.
  • About 20% of 18- to 30-year-old white women who use tanning beds show signs of tanning addiction. When they don’t tan, they even report feeling fidgety or depressed.

And, finally, a Forbes article laid out the issues with indoor tanning as well as some research that shows our desire to tan may actually be influenced by genetics! — WTF fun facts

WTF Fun Fact 12722 – A Tenth Of A Cent Of Savings

Yes, we know. When gas prices are over $5/gallon for even the cheap stuff, no one wants to talk about gas prices.

But chances are you’ve stared a little harder than usual at the prices on the signs lately. And if you’re observant, you’ve probably noticed that more often than not, those prices end in 9/10 cents.

Part of the reason is historical. In the early 20th century when states began taking gas to help pay for highway repair, they did it in increments of a tenth of a cent. That entire cost got added on to gas prices and passed along to drivers. But when gas was 9/10th of a cent back in the day, rounding up would have been a huge 10% hike.

Today, rounding up would hardly even register to most of us, but the pricing is part tradition and part marketing.

Nearly all prices are rounded down to the previous dollar (except for luxury goods, where paying a premium is no big deal). Think about how many prices end in 99 cents. It’s purse psychology.

Marketers study human psychology in order to understand what will make us buy things. And it turns out that we are far more likely to buy something that is $9.99 rather than $10. Our brains process that as real savings (because we’re paying in the nine-dollar range instead of the ten-dollar range).

It’s called “just-below pricing,” and it’s used everywhere. And it’s so effective that even the news doesn’t necessarily pick up a story on gas prices until they hit a new full dollar mark.

Meanwhile, there’s not much of a difference to our wallets if gas is $4.99 and 9/10ths a gallon. But seeing $5.00 and 9/10ths sets everyone off in a whole new way. — WTF fun facts

WTF Fun Fact 12721 – The Wara Art Festival

Niigata isn’t a typical travel destination, but it does draw people in for a unique festival held each year between August and October.

The Wara Art Festival is held in Uwasekigata Park and shows off amazing sculptures made of rice straw left over after the annual rice harvest.

People weren’t quite sure what to do with all the straw, but now tons of it is donated to art students at Musashino Art University in Tokyo as well as local volunteers who are tasked with making giant animal sculptures with it. Some of them are up to 16 feet tall!

The sculptures include gorillas, dinosaurs, bears, rhinos, and more. Underneath is a wood frame skeleton to ensure the sculptures stay up throughout the festival, but over two weeks, more and more layers of wara are added. Some are braided, others thatched – in fact, there are many techniques the artists use to build their sculptures.

If you do go to Niigata for the festival, be sure to try the rice, which is considered to be the best in all of Japan. And according to Japan’s tourism association, the town is also known for its sake as well “thanks to the high snowfall in the prefecture which creates pristine conditions for rice growing. Centuries-old sake making traditions are kept alive by the toji, or Sake Masters, of Niigata. Local sake from breweries in Niigata are revered nationwide for their dry, sharp finish and refreshingly crisp flavour.”

If you visit the park, there are sake breweries within walking distance as well as beer breweries to visit. — WTF fun facts

WTF Fun Fact 12720 – Let Them Eat Cake

We’ll spare you some of the legal jargon, but we did actually read the 51-page judgment of an Irish court declaring that the bread used by restaurant chain Subway is now basically considered a confectionary in Ireland.

It wasn’t exactly riveting, but it was enlightening. And to summarize – it all had to do with paying taxes. Otherwise, we doubt Ireland would have bothered to consider it any more closely. And no one is saying you can’t call it bread – the judgment is only referring to how the bread is categorized for tax purposes.

This started when an Irish Subway franchisee, Bookfinders Ltd. filed a suit claiming that they were due a refund for value-added tax (VAT) payments between January 2004 and December 2005.

Their argument hinged on 2 paragraphs of the Value Added Tax Act of 1972, which described which goods and services should have VAT added to them. Bookfinders claimed that the majority of their goods fell into the category requiring a 0% rate (rather than the 13.5% they had paid).

That category includes: “chocolates, sweets and similar confectionary (including glacé or
crystallised fruits), biscuits, crackers and wafers of all kinds, and all other confectionary and bakery products whether cooked or uncooked, excluding bread…”

And “bread” is specifically defined as “food for human consumption manufactured by baking dough composed exclusively of a mixture of cereal flour and any one or more of the ingredients mentioned in the following subclauses in quantities not exceeding the limitation, if any, specified for each ingredient…”

To spare you more jargon, we’ll just say that the subclause in question is the one that says that in order to be considered bread, the weight of any fat, sugar, or “bread improver” cannot exceed 2% of the weight of the flour included in the dough.

It actually gets pretty complicated since there are different tax rates for different items and part of the argument is about averaging out tax rates, how tax rates might differ for businesses offering primarily take-out goods, and whether the temperature of the food makes a difference when it comes to taxing it.

This might be the very best (and by best we mean absurd) sentence: “They [Bookfinders] also submitted that the 1972 Act breached the principle of legal certainty by making the difference between ambient air temperature and the temperature of the food central to their VAT classification.”

Anyway, in the end, the fact that Subway’s bread had too much sugar in it (5 times as much as allowed by the tax code), means it is not considered bread for tax purposes.

Subway was pretty miffed at the implication that their bread was not bread, saying:

“Subway’s bread is, of course, bread. We have been baking fresh bread in our restaurants for more than three decades and our guests return each day for sandwiches made on bread that smells as good as it tastes.”

Our favorite commentary on the matter is this Tweet:

If anything, people got a warning that their sandwich bread had a lot of sugar in it, but there doesn’t seem to be much proof that anyone cared. — WTF fun facts

WTF Fun Facts 12719 – When Weather Kills

Heat waves (typically regarded as 3 or more days in a row with a temperature above 90 degrees) are a time to take special care and to check in on the elderly and those with young children who may need help. While the heat makes many of us miserable, it’s also a killer. And because it gets misdiagnosed and is considered a fact of life in the summer by many, we easily forget what a calamity it can be for some (even for those with A/C who experience increasingly frequent power outages!).

Technically, all heat-related deaths are preventable. That’s why it’s so sad that around 658 Americans are killed by extreme heat each year. And the numbers are likely much higher since heat-related deaths aren’t mandatory to report to public health agencies.

Heat deaths as well as deaths in which heat was a contributing factor are easy to misdiagnose or mislabel. Looking back at deadly heat waves in Chicago and Paris, for example, show that far more deaths were related to heat than were recorded at the time.

Here are some sobering facts from the Environmental Protection Agency:

  • Between 1979 and 2018, the death rate as a direct result of exposure to heat (the underlying cause of death) generally hovered between 0.5 and 2 deaths per million people…
  • A total of more than 11,000 Americans have died from heat-related causes since 1979, according to death certificates.
  • In some years, recording has included heat as a contributing factor, and in other years it has not – but in the years where only direct heat deaths “counted,” the estimates may be twice as high as the records show.
  • There was a peak in heat-related deaths in 2006, one of the hottest years on record in the contiguous 48 states.

And while many kids do get special attention during traumatic weather events, it’s the elderly who are often forgotten. However:

  • Since 1999, people aged 65+ have been several times more likely to die from heat-related cardiovascular disease than the general population, while non-Hispanic Blacks generally have had higher-than-average rates.
  • The interaction of heat and cardiovascular disease caused about one-fourth of the heat-related deaths recorded since 1999.

According to the CDC, those most likely to suffer from heat-related illness and death include:

  • infants and children up to 4 years old
  • People 65 years of age and older
  • People who are overweight
  • People who have existing medical conditions, such as diabetes or heart disease
  • People who are socially isolated
  • Those who take medications that impair the body’s ability to regulate its temperature or that inhibit perspiration
  • People who are poor

Behaviors that put people are at risk for serious illness or death during heat waves include:

  • Those who engage in strenuous exercise during high heat
  • People who drink alcoholic beverages during high heat

Heat is also worse in urban areas where buildings, parking lots, sidewalks, and roads absorb heat and create even hotter “heat islands” that aren’t recorded in the local weather estimates.

From 1999 to 2010, 8,081 heat-related deaths were reported in the United States. In 72% of these cases, excessive heat was actually the underlying cause of death (often in those who already had a cardiovascular condition). Only in 28% of cases was it a contributing factor.

So, what can you do to make sure everyone handles the heat?

  • Check on people at risk, such as the elderly, disabled, or homebound.
  • Never leave any living creature locked in a car. (Sometimes we don’t even know how bad the heat is getting to us until it’s too late.)
  • Limit sun exposure during midday hours, even at places like beaches.
  • Avoid sunburn and treat it right away if it happens by applying aloe vera and hot compresses – never pop blisters.
  • Drink plenty of nonalcoholic fluids (and avoid caffeine).
  • Replace the body’s salts and minerals by eating fruits and vegetables (NOT salty snacks – because while your body needs salt, they have too much for your kidneys to handle).
  • Dress in cool, loose clothing (this also helps avoid heat rash).
  • Shade your (and especially children’s) heads and faces from the sun – use an umbrella if that’s all you have.
  • Provide plenty of fresh water for pets and put it in the shade.
  • Create circulation with fans if you don’t have a/c – and make there’s a fan pointing outward to push hot air out of the room.
  • Put a bowl of cold water (with ice, if possible) in front of a fan for an extra cooling effect.
  • Try closing all doors, windows, and curtains right before the sun comes up to keep cooler evening air inside longer.
  • Cover your feet and shoulders with wet towels and washcloths.
  • Create a space in the basement, if you have one, since it’s often cooler down there.
  • Turn off electronics that give off heat when plugged in (such as computers and lamps with incandescent light bulbs).
  • Try not to use the stove or oven.
  • If there’s no relief in your home, visit public buildings (such as shopping malls or libraries) with air conditioning.
  • Avoid large, protein-rich meals to keep the body from creating its own metabolic heat.
  • Lay down in a shaded area and sip water if you get clammy, pale, lightheaded, nauseous, or develop a headache – this can turn into an emergency quickly, so don’t hide away in a hot room.
  • Keep some Gatorade or Pedialyte (or any oral hydration with essential minerals and potassium) to stave off dehydration.
  • Call 911 if you experience: cramps, swelling, fainting, a temperature over 100 degrees and rising, confusion, a rapid pulse, severe nausea, a severe headache, and skin that’s warm and dry – it could be heat stroke, which can lead to coma and death.

WTF Fun Fact 12718 – Crickets Can Tell You The Temperature

Let’s get one thing out of the way up front. While we call the method of measuring temperature using cricket chirps “Dolbear’s law,” the idea was first laid out in 1881 by Margarette W. Brooks. Her report “Influence of temperature on the chirp of the cricket” was published in Popular Science Monthly, it just wasn’t noticed until after Amos Dolbear published an 1897 article called “The Cricket as a Thermometer” 16 years later.

Regardless, it’s known as Dolber’s law, and it states that there is a connection between the air temperature and the rate at which crickets chirp. And it’s accurate for the field cricket within about 1 degree Fahrenheit.

It’s kind of like counting the seconds between lightning strikes and thunder, except way more inconvenient.

However, it is true that crickets chirp more speedily as the weather warms up. Dolbear realized this because crickets chirp consistently – that makes it possible to use the numbers in an equation.

In the original paper, Dolbear said you can get the approximate temperature in degrees Fahrenheit based on the times a cricket chirps in 1 minute – but you have to do some more math.

T_{F}=50+\left({\frac {N_{{60}}-40}{4}}\right).
In other words, T = 50+[(N-40)/4]
T = temperature
N = number of chirps per minute

If you want a shortcut for Celcius, you can use the number of chirps in 8 seconds and add 5.

Of course, there are many types of crickets, and Dolbear realized they each had a different rate of chirping. So he created new equations for other species. The problem for us is that we have to know which type of cricket we’re dealing with.

In fact, the common field cricket really isn’t the best cricket to use since its age, and whether it’s mating season can also affect the speed at which they chirp (so they’re not entirely consistent). But they’re probably good enough for a quick experiment. –WTF fun facts
