What is a piece of information that you believed where true, but find out it is mnot?
Well, there is no exact question in musing that is like that but there are similar ones, so i might not deserve to be up-voted, yet I find that my answer would not fit in there question so this is a more broader one.
Anyway for me the first wrong fact I believed or thought was true is the fact that heart beats is produced from the movement of the muscles during beating. they in fact do not, however they are formed from the closure of valves in the heart allowing the blood to leave and go between chambers in the heart.
When I was young, I was told that should I lose a tooth and I allowed a lizard to see the tooth, that the tooth would never grow again in my mouth. They would show us some advanced men that some of their teeth have fallen off as a proof to the belief and I used to believe it was true. Whenever I lose a tooth I would quickly rush to bury it in the earth or throw it on top of the roof of a building since lizards hardly visits those places. Funny! Now that I am grown, I've discovered that it's a lie. Every individual stops producing new tooth after a certain age or when the number of teeth in their mouth have been fully grown
I used to believe that breeze came from trees. It was a common belief among the children back then and our reasoning was that it was always cool under trees and a bit windy. But later I learned that tress are actually wind breakers. Which means they stop wind. And that breeze is actually a result of the sun heating up the Earth unevenly. Because of this formation of hot parts and cool parts. A temperature gradient is created and as such, a pressure gradient. This causes the air to flow from the region of high pressure to the region of low pressure.
Consuming food/drinks high in Sugar makes one hyperactive!
It's a common belief around parents worldwide in which many believe and claims that after their kids eat sugary food/drinks they become hyperactive. I'm no parent myself but after hearing that a lot from many people around me, I honestly thought it was true.
After reading a lot of articles online regarding this one, it seems to be not true. There is just no scientific basis supporting this claim. There was even a study in which kids where given a sugary food/drink for a week but it didn't make them hyper.
I believed in Santa Clause and found out that he is not reality :(
