Admit It, You Still Believe At Least One of These Myths

Take a look at this list of common myths and see how many you still believe.

1. Cracking your knuckles causes arthritis.  This might cause weakness in your hands but there isn't any proof that it lead's to arthritis. Something else I remember about cracking your knuckles is that it's tiny bubbles bursting that make the noise. This is true.
2. We only use 10% of our brain.  Apparently two-thirds of people still believe this. In reality, we use the majority of our brains, even when we're sleeping.
3. Dogs see in black-and-white.  Dogs do see some colors, just not as many as we do. The are essentially red and green color blind, meaning they see the world in yellow, blue, and gray colors.
4. If you swallow a piece of gum, it takes seven years to digest.  This would mean the gum gets stuck in your insides somewhere for 7 years, and then it either randomly gets digested or expelled from your body. In reality this is similar to corn. Your body just doesn't digest it, but it still goes through your system quickly.
5. You swallow eight spiders a year in your sleep.  This "fact" was actually started to show how quickly misinformation can travel on the Internet. Lisa Holst, a columnist for PC Professional started the whole thing in an article from 1993.
6. Public swimming pools have a chemical that turns blue if you pee in them. This myth could have been with red dye or purple dye, but it apparently never existed. I remember the first time I had heard this rumor I was summer camp and all the counselors were adamant that this thing existed and to not pee in the pool. All I can say is the scare tactic worked. No one was peeing in that pool.
