True or false

in #steemit7 years ago

Remember when you were a kid and you liked to know the why of everything?
If you still have that same curiosity .. I will invite you to continue reading this post ..

True o false

1- The myth says that you can see the Chinese wall from outer space ... and not only this but you can even see it from the moon .. will it be true?
When an astronaut travels to outer space you can clearly see the boundaries of continents and countries, seeing some detail like man-made buildings is totally impossible! Even from the space station that is 278km from the earth is impossible to see the wall and much less since the moon.

What you really see.

2-Is it true that fish have poor memory? As we have been told they can only remember what happened a few seconds ago.
It's fake: In fact these animals are smarter than you imagined, they can remind each of the predators that they had before and can even learn tricks!
If they associate sounds with food they can do the same tricks as a dog would ... is not it amazing?

3- And this is one of the most common lies spread by our parents, grandparents, and uncles, they said that if we swallowed a gum this was going to stick to our stomach for years! (Oh, how much evil in those minds)
The truth is that it is a big lie. Because if the chewing gum stays wet there is no way to stick it,.

4- We have all heard that when a person or animal dies their nails and hair continue to grow.
This is false and I will tell you why .. our nails and hair do not contain large amounts of water as our skin, which begins to shrink when we die and this causes the illusion that the nails and hair continue to grow !!!

5- Another thing that is common to hear is that the blood is inside the body is the color of our veins, it may be blue or green, and it turns red when leaving our body - FALSE -
although there is something Truth in this is that the blood changes from a bright red color (because it is oxygenated inside the body) to a darker red when it has no oxygen..

5-Do we only use 10% of the brain? So if we took the remaining 90%, nothing would happen?
The brain weighs around 1400g and if you removed 90% you would only have 140g of brain .. easier? You would stay with the cerebellum of a sheep ...

Actually we use 100% of the brain even when we are sleeping .. there is not a single part that is turned off or unusable !!!
