With TV shows like Mythbusters on the air now, many old wives tales and urban legends are finally being exposed for what they are – myths. Here now some things which mainly of us believe, but which turn out to be plainly untrue.
The Great Wall Of China Is The Only Man Made Structure Visible From Space
We’ve heard this one since we were school kids, depending on our age of course, but it turns out that astronauts can spot several other human crafted things while in low-Earth orbit, including; the Giza Pyramids and even many airport runways.
Humans Only Use 10 Percent Of Their Brains
Some would say certain people use even less, but all jokes aside this just isn’t true. Modern marvels like MRI imaging can now clearly show that we utilize most of our amazing cerebral cortex to maximum efficiency.
Adults Don’t Grow New Brain Cells
Here again, some people would say that by virtue of the thickheaded people in our lives, this has to be factual, but it isn’t. While it’s definitely true that most crucial brain development does occur during childhood, numerous studies have shown that neurons continue to grow and change well into our adult years. That’s a relief to an aging population!
Animals Can Predict Natural Disasters
Does Fido or Fluffy have a sixth sense when it comes to earthquakes or storms? Sorry, but no. There’s just no evidence animals posses any mysterious sense which warns of natural disasters. They do have keen senses of hearing, smell and other sharp instincts which most likely sends them scampering off sooner when disasters do hit, but the overwhelming numbers which die in natural disasters tells us this is fable.
A Penny Dropped From A Skyscraper Will Kill
Pennies are far too light and also lack any real aerodynamic properties to be of much danger. Their light weight combined with wind friction means that even tossed off the Empire State Building would only give a passerby a bad sting. Ouch, but hardly fatal.
A Dog’s Mouth Is Cleaner Than A Person’s
Fido’s mouth may be smellier or just plain unattractive to humans, but you just can’t compare it to a person’s mouth. Oral bacteria are finicky things; they’re so species specific that it’s not really dirty to us human beings, just different. Does this mean you can go around kissing your dog on the mouth? Well, that’s your business – and his!
The Five Second Food Rule
Gorge or garbage? Drop a piece of food on the floor, so be quick! Eat it before five seconds and all is well? Not really. Numerous tests performed just don’t bear this one out. Germs can stick right onto food upon contact. Wash it off? Maybe, but I’d leave it for the cat.
