If there’s one thing I’ve learned is that you shouldn’t believe everything you are told. That’s because many things you’ve already heard are not even close to being true. For years now, you learned that it’s wrong to do this or that, without getting any explanation on why you shouldn’t. Since your parents weren’t able to justify the reason, you assumed that what they said was true and that was the end of it.
However, there are many misconceptions about how the world works. These myths you’ve come to believe are just stories previous generations didn’t know how to explain. With the word of mouth the facts became twisted and embellished as everyone wanted to integrate their own story in an attempt to make it more interesting.
In order to help you understand what I mean, check out the 8 most popular misconceptions that currently exist:
1. You shouldn't wake a sleepwalker
I’m sure you have heard that you shouldn’t wake a sleepwalker as this will give them a heart attack or shock them in some way, but this is just a myth. In reality, doing so is more dangerous for you than the person who is sleepwalking.
If you wake a sleepwalker, they may not recognise you and attack you as the waking will leave them startled and confused. This happens because sleepwalking occurs during deep sleep at stage 3 and waking them will cause sleep inertia (cognitive impairment) for about 30 minutes. Check out the video above to learn how sleepwalking works in reality.
2. A Third-world country is a poor country
When you listen to the phrase ‘third-world country’ what comes to your mind? Many people think that a third-world country is an underdeveloped country, but this is not entirely the case. This phrase describes a country that’s not considered to be a capitalist country or a communist country. These country divisions were formed after the WWII as those countries aligned with the US were called ‘first world’ countries, and those aligned with the Soviet Union ‘second world’ countries. Other countries around the world were then called ‘third-world’ countries and since most of them were poor and underdeveloped, this popular misconception still exists today.
3. Fish have a three-second memory
Studies have shown that goldfish are not as forgetful as originally believed and that they can remember things for up to five months. Scientists came to this conclusion after examining how the fish reacted to certain sounds while in captivity. When it was feeding time, they would hear this sound and the fish knew that they were about to eat. Months later when the fish were freed in the ocean, they still remembered and reacted to the sound returning back to get their food.
4. Humans have only five senses
Forget all about what you have been learning at school. The truth is you have at least nine senses and even more than that. Apart from hearing, sight, touch, smell and taste, you also have thermoception (the ability to sense heat and cold), proprioception (ability to tell where your body parts are in relation to other parts), tension censor (ability to control muscle tension), thirst, hunger, pain, movement and time. Although the latter is not yet confirmed there is evidence that humans have a surprisingly good sense of time.
5. Camel humps are full of water
No they are not. Camel humps are full of fat that weights up to 80 pounds and can be used to allow the animals to survive for up to two weeks without food. While 1 gram of fat is converted to more than one gram of water, they don’t use this as a water supply. Instead in order to stay hydrated, they store extra water in their blood and other places where there is fluid in their bodies.
6. You shouldn't eat and then swim
How many times your parents told you to wait an hour before you can swim again after you have eaten? While this is good advice, diving in the pool or the ocean right after eating won’t give you cramps despite popular belief. It will however, make you short of breath because your stomach is full, and this is still pretty dangerous.
7. Being close to the TV can damage your eyes
Sitting close to the TV won’t damage your eyes or your vision in any way. Despite the fact that parents around the world still say this to their kids, TVs are not as harmful as they originally thought. They might have been in the past though, when General Electric TVs were in fashion around the ‘60s. These TVs were producing excessive x-rays due to a “factory error” and GE had to fix this by adding a glass shield around them.
8. Black holes are giant cosmic vacuum cleaners
Black hole misconceptions are common as many people are quite confused about what these are. Since black holes are hard to come by on earth, they sound unnatural and bizarre to our ears, and it’s hard to believe they even exist. So to get things right, black holes are not holes at all. They are huge dense objects that have a massive gravitational pull and are just called black holes because anything that goes in it’s gone forever. Also, they don’t pull everything in or else the entire universe would have been sucked in. It’s either that or we are living in a black hole! Imagine that.
