Tired Old Myths People Still Believe


Here are a few myths a lot of us still believe: We don’t only use 10% of
our brain. Dogs don’t see in black-and-white. Shaving doesn’t make your hair grow
back thicker. And you don’t swallow eight spiders a year in your sleep

Myth #1: Cracking your knuckles causes arthritis. It might cause weakness in your
hands, but there’s no proof it causes full-on arthritis.

Myth #2: We only use 10% of our brain. A survey a while back found two-thirds of us
believe that one. But even with simple tasks, you’re still using most of your brain. It
takes so much energy that up to a fifth of the calories you eat go toward keeping your
brain working.

Myth #3: Dogs see in black-and-white. The newest science says they probably DO
see colors, just not as many as we do. They’re basically red-green colorblind.

Myth #4: If you swallow a piece of gum, it takes seven years to digest. The truth is that
just like corn, your body CAN’T digest it. But it doesn’t stay in there for seven years. It
moves through your body just like everything else you eat. It just doesn’t break down.

Myth #5: Shaving makes your hair grow back thicker. Some people think that because
the tips of your hair feels coarser after they’re been cut. But shaving doesn’t make it
grow back thicker
