How many cups of coffee did the inventor of Coca-Cola drink every day? What’s the origin of the phrase break a leg? How many times can you subtract 10 from 100 before you get to 0? These are all facts that will blow your mind, but there are so many more! Read on to find out more about facts that will surprise and amaze you, even if you’re not into trivia games.
1) The human body is made up of 7% iron
The human body contains 7% iron. Iron is one of the most common metals on Earth and is an important component of our red blood cells. Iron can be toxic to people if they have too much, but in many cases, we only need to eat a little more than usual to maintain healthy levels. Eating plenty of leafy greens, for example, helps improve the absorption of iron from food.
A single square inch of skin has 200-250 sweat glands: A single square inch (6.5 cm) of skin has around 200-250 sweat glands which produce about 1/2 teaspoon (1-2 ml) each day. That’s a lot! Sweat helps cool us down when it evaporates off our skin because it takes heat away from our bodies with it as it does so.
When you are running or exercising vigorously, this process goes into overdrive to help keep your body temperature regulated. Your body also produces sweat because it needs water to cool itself off – without water, the high concentration of salt in sweat would cause dehydration. Did you know there are different types of sweat? We make two kinds of sweat, apocrine and eccrine.
Apocrine comes from the larger apocrine glands located near hair follicles in areas like our armpits or breasts. Eccrine sweat comes from small eccrine glands found all over the body and contains mostly water with some other substances like urea, ammonia, fat, sodium chloride, potassium chloride and lactic acid.
2) You can survive longer without water than food
Every human is born with about 3,500 calories’ worth of energy in the form of fat and muscle. However, as we get older, these stores of energy slowly start to dwindle, which is why it becomes easier for seniors to lose weight and maintain a healthy lifestyle than the younger generations. Humans can survive about 15 days without food but only 3-5 days without water! So keep hydrated and stock up on bottled water or at least have some portable bottles handy if you’re traveling or hiking.
A new study shows that people who drink soda daily are more likely to be overweight: The study found an association between drinking soda and obesity – but not an actual cause-and-effect relationship. Researchers looked at data from 6,000 adults over the course of 22 years. They measured how much sugar-sweetened beverages they drank and their body mass index (BMI).
The researchers also accounted for other factors that might contribute to obesity such as age, education level, exercise habits, smoking status and total calorie intake. What they found was that those who drank the most sugary drinks were 25% more likely to become obese than those who drank less.
What’s interesting about this study is that even though it didn’t establish a causal link, there does seem to be an association between drinking soda and being overweight. That’s something many people might want to take into consideration when choosing what type of beverage to consume.
3) An ant’s heart is twice as large as its brain
An ant’s heart is roughly twice as large as its brain and has the strongest propelling force of any arthropod – it can pump at a rate of up to 80 beats per second. Ants are also one of the few types of insects that produce sounds, making clicks in their abdomens that they use to communicate with one another. If an ant colony is disturbed, some ants may emit an alarm pheromone that sends nearby ants into a defensive frenzy, even if there’s no immediate danger.
If threatened by fire or extreme cold, most ants have the ability to form clumps around the queen called heat nests or cold nests for warmth and protection until help arrives. The best-known type of ant worker is the queen who lays eggs and oversees all other tasks within the colony. There are many different species of ants found on every continent except Antarctica. Some species live underground while others live in trees or under rocks.
The word ant derives from the Latin word ante, meaning before. The smallest ant known to science is only 0.13 millimeters long and lives on trees in Thailand; this tiny insect can be hard to spot because it blends so well with tree bark! The largest ant species on record belongs to a Brazilian rainforest species: these creatures grow as big as 6.3 centimeters (2.5 inches) long, excluding the mandibles!
4) Chocolate kills dogs
Chocolate contains a chemical called theobromine, which can cause an upset stomach in humans and is toxic to animals. It’s toxic because it affects their heart and central nervous system, causing dogs to suffer from vomiting, diarrhea, muscle tremors, abnormal heart rhythms and seizures. The lethal dose for chocolate in dogs is 100-200mg per kilogram of body weight.
Methane isn’t just from cows: Methane gas comes from decomposing plant matter too! There are only two ways of communicating with a fish: Fish don’t have ears so they can’t hear anything above water. They also don’t have vocal cords so they can’t make any sounds above water either. They use vibrations to communicate below water though, so if you’re ever scuba diving with fish they’ll be able to feel your vibrations as if they were talking to each other!
A lemon contains more sugar than an apple: Apple has about 5 grams of sugar while lemon has 10 grams. Lemons actually have less fructose (a natural type of sugar) than apples do, but lemons contain more glucose (another type of natural sugar). Lemons also contain some sucrose (table sugar), but apples don’t. And even though lemons contain more sugars overall, there’s not enough juice in one lemon to sweeten a cup of tea or coffee.
5) Cats have 9 lives
Facts about cats are some of the most popular Google searches of 2017. But did you know they actually have 9 lives? Why not spend a day learning all the cool things about this pet we love so much! It is National Cat Day after all!
-In honor of National Cat Day, take a break from scrolling through Facebook and watch these cute cat videos!
-The average lifespan for a cat is 12 years, but some breeds can live up to 20 years.
-Cats sleep an average of 16 hours per day and can see at night better than humans because their pupils enlarge to let in more light.
-A group of kittens is called a kindle or litter
-Cats have scent glands on their faces, lips, neck and paws. They rub against furniture and people to mark their territory with pheromones. Cats also lick themselves to keep clean and maintain healthy skin and fur.
-There are 39 species of wild cats worldwide, including lions, tigers, leopards, cheetahs and jaguars. Domestic cats aren’t considered wild animals because they depend on humans for food.
-The first domesticated cat was discovered near where Nineveh used to be located around 4500 BC by a farmer who found the kitten near one of his grain stores.
6) According to Einstein, 99% of the Universe is unknown
And of course, if we only knew what the other 1% was made up of. Until then, these five facts about space should be enough to keep your stargazing fire burning bright for a little while longer.
1) There are more stars in the Universe than there are grains of sand on all the beaches on Earth.
2) You can’t see as many stars in cities as you can in rural areas because there’s too much light pollution
3) The Moon is closer to Earth than any other moon in our solar system: It orbits at an average distance of 238,900 miles away from us. That’s roughly 30 times farther away than the next-closest planet, Mercury.
4) Our galaxy, the Milky Way, contains about 400 billion stars and has been around for 13 billion years. But it’s not just this galaxy alone – there are some 100 billion galaxies just like ours spread out across the universe. So go outside and look up – you’ll be amazed at how far out into deep space your eyes will take you!
5) A black hole is a phenomenon where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. If this happens, the black hole will continue to grow. The gravity of a black hole is so strong that not even light can escape it. Black holes come in two types: small ones with the mass of our sun and large ones with millions or billions times more mass than our sun. Smaller ones are called stellar-mass black holes; larger ones are called supermassive black holes (which power quasars).
7) A crocodile cannot stick its tongue out
A common misconception is that a crocodile can stick its tongue out. But, they cannot. The inside of the mouth is not connected to the outside of the mouth and, hence, there is no need for the tongue to protrude from it to enable it to suck up food. Crocodiles swallow their prey whole or rip it apart with their teeth.
They then allow the prey’s stomach acid to break down the tissue in their throat before digesting them in their stomachs. In contrast, lizards have tongues which they can use to catch insects. They also use their tongues to help push objects into their mouths. They curl their tongues around whatever they are trying to eat, like a snake would.
When they want to release an object they’ve caught on their tongue, they press it against the roof of their mouth with one of the spines on the underside of their tongue called papillae. It works just like a conveyor belt where the tongue pushes what has been captured forward towards the front of the mouth.
Their saliva contains enzymes which start breaking down the food while they’re still eating it so that by the time it reaches their stomach, there is nothing left but liquid nutrients. A sloth spends nearly all day hanging upside down: Sloths spend nearly all day hanging upside down – except when they descend from their tree at night to go to the ground and feed on leaves, shoots, fruit, twigs and cecropia leaves. The giraffe’s tongue is 20 inches long: Giraffes’ tongues are 20 inches long! That’s about half as long as their entire body!
8) There are no clocks in Las Vegas casinos
The first casino in Las Vegas opened in 1905 and time never mattered until the mid-1960s when they added a few clocks. There are no clocks in any of the casinos so gamblers don’t count cards based on how long a deck has been dealt. Casinos did this to limit people from counting cards. A card counter is someone who counts cards, usually in blackjack, by noting which cards have already been played or face up, and guessing which might be drawn next.
For example, if six 10s have already been played out of an original 52 card deck, then there would be only 16 left (52 divided by 4). Knowing what’s left makes it easier to guess whether a card coming up is likely to be higher or lower than those still hidden. Gamblers can also use their knowledge of probabilities to improve their odds. In order for a card counter to succeed, he must predict with about 80% accuracy every round about whether the new card is more likely to be higher or lower than the other cards left in the deck.
Casinos say there is no advantage for players because even with perfect information about what’s remaining in the deck, a player would need tremendous luck to consistently beat Blackjack odds over time. Many of these games involve bets on things like red and black; odd or even; high hand or low hand.
When playing roulette, there are 38 numbers on the wheel: 0-36 plus 00 and 1/2. These numbers correspond to numbers 1 through 36:One can make single number bets or multiple number combinations. You win if your bet matches one of the winning betting combinations at the end of the spin. So where do chips come into play?
