popular myths

How many of these sayings do you think are true?

  • It takes seven years to digest gum.
  • The Great Wall of China is the only manmade structure visible from space.
  • Humans use only 10 percent of their brains.
  • Adults don’t grow new brain cells.
  • Water drains backwards in the Southern Hemisphere due to the Earth’s rotation.
  • Animals can predict natural disasters.
  • A dog’s mouth is cleaner than a human’s.
  • Lightning never strikes the same place twice.
  • A falling cat will always land on its feet.
  • Yawning is “contagious”.
  • There is no gravity in space.
  • The “five second rule” of food dropped on the floor.
  • Hair and fingernails continue growing after death.
  • You get just as wet by walking or running in the rain.

What do you think?

I’ve heard every single one of those in my lifetime, yet they’re all false. Some are partially correct, like that a cat will usually land on its feet. Some are not true at all. It’s amazing how these myths get spread from generation to generation, yet they’re not true. (And what can really burn your biscuits is to wonder how much stuff people believe that isn’t true, and that each of us are probably deceived in some way about some things. I’ll write more on that in future episodes.)

You can read the explanation for each of these (and more) at LiveScience.com.

You need to expound on the more! For instance, regarding the Great Wall of China, are you saying that other man-made structures are visible with the naked eye from space or that no man-made structures are? And what about Humans use only 10 percent of their brains – if not, how much do we use? And how do you know?? Just who do you think you are, N-E-Way???

Check out the link to LiveScience.com to read more about each of those.

About using only 10% of our brains, the scientists are saying it all functions together physically, like a network. But if you’re coming from the angle of whether we use more than 10% of the potential of our brain, that might be debatable for a lot of people…

As far as the brain issue. Our cognative part of our brain is the extreme frontal part of our brain, approximately 10% of the total brain mass. This is the part where everything that makes you, you is contained. Your mannerisms, Your accent, Your likes, dislikes, How you act, How you think…etc. It’s all in the front 10%. That is why so many people who get a brian injury in the frontal lobes, wind up being in a vegetative state the rest of thier lives.
