6) Cold weather causes colds.
Contrary to concerned mothers everywhere, cold weather does not contribute to catching a cold. Actually, it’s the warm air being recirculated throughout your house in the winter time that spreads the virus.
So next time your mom tells you to bundle up, tell her to open a window and turn down the heat!
7) Eating carrots improves eyesight.
During WWII, The U.K. Ministry of Food told British civilians that the key to our pilot’s success is navigating the dark was eating carrots, and they encouraged people to eat more in order to withstand any blackouts during the war. According to Scientific American, theories suggest that this carrot campaign was manufactured to distract from new top secret night vision technology.
The truth is, unless you are deficient in Vitamin A, eating carrots won’t do a damn thing for your vision. If you are deficient in Vitamin A, you’d have to eat a truckload of carrots to see things clearer.
No thanks, I’ll stick with glasses.
8) Blood is blue until it's exposed to oxygen.
9) You can't teach an old dog new tricks.
According to Wonderopolis, historians have traced this common saying all the way back to 1523. Yet, while the phrase has been around for hundreds of years, it’s not entirely accurate.
10) Bats are blind.
Bats aren’t blind. Actually, they can see almost as well as humans do. While they do rely on their hearing abilities at night by using echolocation capabilities to navigate caves and dark places, they can still see just fine. In fact, some species of bats can even see ultraviolet light rays that humans cannot.
So if anyone ever tells you that “You’re as blind as a bat,” take it as a compliment.
Additional proof that this common saying is baloney: Batman.
