Back in the days when you were younger, you were taught about various things around you and you even read things in textbooks that were difficult for you to understand. As you grew older, you eventually realized that sometimes, those textbooks screwed up and got the facts wrong.
Have you ever questioned those false claims? Not everything you have seen or heard were true; and those things that you have always thought to be true can sometimes be false as well. Some of those “facts” were made out of blissful ignorance or only to make fun of you just for the sake of celebrating April Fool’s day. And although April Fool’s day is celebrated once a year, some people just can’t help but to make false facts to make people believe of something for the sake of their own entertainment. From urban legends, hearsay, hoaxes, to mere conclusions of a person, here are the 10 misleading facts that we actually thought were true ever since – but in reality, they were just pure lies.
10. Our Tongues Have “Zones” For Different Tastes
Our tongue’s four zones are liable for different basic tastes. The tip of our tongue detects sweetness, the sides are for salty, bitter is in the back, and sour is between where the bitter and salty regions are – that is what we were taught in primary school. But those textbooks showing tongue maps were wrong.
Scientists from Columbia University revealed that we detect tastes because of the neurons in our brain – not only because of the regions in our tongue. So the next time you eat a pretzel, remember that it is okay to put it on the tip of your tongue.
9. Chameleons Change Color To Blend With Surroundings
Remember Randall from Monsters Inc. whose character resembles a chameleon and purposely changes his color whenever he goes incognito to scare children? This is how people would commonly describe a chameleon – that it changes its color mainly to hide itself from a predator.
To begin with, chameleons are camouflaged with their normal coloration; and the reason behind these changing colors (contrary to what many people believe) is because it is triggered by emotional changes. If they feel angry, afraid, or aggressive they would change their color using their color-bearing cells. Also it is their way of communicating with each other.
8. Humans Have Five Senses
Another “fact” that we were taught when we were younger is that humans have five senses – sense of smell, sense of touch, sense of sight, sense of hearing, and sense of taste. And if you would get punched in the face right now, you would feel that there really is more than our five traditionally recognized senses; thanks to our sense of pain which is also known as nociception.
Also, we have equilibrioception or sense of balance, proprioception which helps you pass the cerebellar exam, thermoception or sense of heat and cold, temporal perception or sense of time and many more.
7. Humans Only Use 10% Of Their Brain
We’ve all liked the concept that we could be more intelligent if only we could use our brain to its full potential, because some claim that we only use 10% of our brains. This claim is so widely spread that a movie was even made based on this trivia.
This is merely a myth, though. In fact, we use far more than 10% of our brains. And even while a person is at rest, modern brain scans reveal that there is still activity going on our brain. Also, there is no scientific proof that humans can only use 10% of the brain.
6. The Great Wall of China is Visible From Space
Many people were told that this great brick wall is the only man-made structure that can be seen from space. Although it extends about 21,196 kilometers, it is, in reality, not the only object visible from space from a low orbit (approximately 160 to 360 miles above earth). Other human-built structures can also be seen, such as highways, tall buildings, dams, bridges, and airports. Also, the material used in constructing The Great Wall made it difficult to recognize from space.
Apollo astronauts and even China’s own astronaut, Yang Liwei, said that the famous wall is not visible from space with the naked eye.
5. The 5 Second Rule
Imagine you were about to devour that delicious piece of chocolate cake but as you are about to put it in your mouth, it fell on the floor; you pick it up, dust it off and eat it. After all, there are still a few seconds left, right?
This “fact” is just a dirty little lie because: 1) germs do not know how to count and 2) a clean-looking floor does not mean it is free from bacteria. So the next time you drop a pizza, the safest choice would be to toss it out in the trash because you’ll never know what kinds of bacteria are hiding out on the floor.
4. The Color “Red” Angers Bulls
Many people think that matadors of Spain use the color red to enrage bulls. This “fact” needs to be taken out of the ring.
Contrary to what many people believe, bulls (as well as cattle) are colorblind. They are not angered because of the color – but because of the movement of the cloth that is being made by the matador. On the other hand, the famous color of the cape (also known as the muleta) is merely rooted with its history and culture; in fact there are colors used for the cape like gold, yellow, blue, pink, or any velvet-colored capes.
3. Soap Kills Germs
For centuries, we have always been told to frequently wash our hands to “kill germs” that could cause us different kinds of diseases and infections. This is another “fact” that needs to be washed out.
Despite the general consensus, soaps don’t actually kill germs. A study by scientists from Korea University revealed that the “magic” of those expensive anti-bacterial soaps, as portrayed in many advertisements, shows not much of a difference when compared to plain soaps. As a matter of fact, what these soaps really do is just lift the bacteria off our skin forcing them to be flushed down the drain.
2. Mt. Everest Is The Tallest Mountain In The World
Mount Everest, which is 29,029 ft. tall, is considered to be the tallest mountain in the world, if we are talking about how high a mountain is elevated above sea level. However, another mountain is taking a stand to compete with Mt. Everest in another category. From its base (below sea level) to its summit, Mt. Mauna Kea leads with a height of 33,500 ft. – almost a mile taller than Mt. Everest.
So, if mountains are measured from their bases to their peaks, indeed, Mt. Everest is not in the first place nor second – it would actually be third, after Mauna Kea and Mt. McKinley.
1. Coffee Causes Dehydration
Hesitated to have that cup of hot coffee in the morning fearing that it might dehydrate your skin? Fret not because this idea is not true. In fact, a recent study showed that moderate consumption of coffee has the same hydrating feature of water. Now, that is good news for coffee lovers. The water, when mixed with caffeine, counterbalances the diuretic effect. However, if not taken moderately, this would cause excessive urinating which could eventually lead to dehydration. Just steer clear of coffee binge-drinking, okay?
Be it coffee or not, we should keep in mind that everything should be taken in moderation.
