10 Facts That Everyone Gets Wrong

How many times has it happened that you know you're right but nobody believes you? You know you can prove it, but you're getting embarrassed and stumbling over your words.

Well, your day is finally here. Let out a deep sigh of relief, because now the world will finally see that you've been right all along. Here are 10 facts you know are correct that everybody else has wrong, from Reddit.

Tae Kwon Do is only around 60 years old

There is a lot of misinformation because Korea wants the world to believe TKD is an ancient art. Some people think I'm saying tae kwon do isn't based on older martial arts. That's not what I'm saying. I'm saying tae kwon do is NOT based on taekkyon or other so called "ancient" arts from Korea and is fact based on karate and a little chuan fa. I lay this all out in great detail in my thesis.

A Car Is Safe In A Lightning Storm

A car is safe during a lightning storm because the metal frame will conduct the electricity around you. The tires have nothing to do with it.

Cracking Your Knuckles Won't Give You Arthritis

I know that cracking your knuckles does nothing detrimental to the joints, but everyone tells me I am going to get arthritis. Can someone provide reliable sources that demonstrate how cracking knuckles reduces grip strength?

There's a doctor who cracked the knuckles on one hand but not the other for 60 years, earning him an Ig Nobel prize (he did it to prove his mother wrong).

We don't only use 10% of our brain

I don't know if anyone really believes this, but since it was like the crux of that Bradley Cooper movie, we don't only use 10% of our brain.

Skunked beer doesn't really exist

Unless taken to extremes (like almost freezing), allowing beer to go from room temp to refrigerator temp to room temp will not cause it to skunk, spoil or otherwise go bad. Beer goes through somewhere between three to five temperature swings between the time it's brewed and the time it arrives in the beer cooler at your local store. If moderate temperature swings had any effect, the beer would all be ruined before the store even received it.

Fans Can't Kill You

Well, I live in Korea, but literally every Korean I have ever had this conversation with believes that fans can kill people under the right circumstances. It's not a once or twice thing; it has been probably 30/30 people, with one girl admitting that she wasn't 100% sure. It blows my mind.

Hold Your Head Forward When You Have A Nosebleed

To hold your head backward when you are having a nosebleed. Tilt itforward, my friends, and hold just above the bridge of your nose.
- ACHollywood

EMT here. Absolutely true. My parents knew about this when I was younger and always had me tilt my head forward. Made things confusing when the school nurse said to do the opposite.

EDIT: I didn't see the part about holding above the bridge of your nose. If ACHollywood is referring to the hard tissue at the top (the part that is resistant to bending), I don't know how effective that is. I always held my nose along the compressible inferior part.

Belly Dancing Is Not A Dance Of Seduction

Belly dance was not a dance of seduction, and wasn't done by harem girls for the sultan. It's a community folk dance with a rich and long history, done by both men and women during family celebrations and gatherings. The two-piece costume was invented by early Hollywood and adopted by Egyptian dancers in nightclubs to cater to Western tourists. The term belly dance was invented at the 1893 World's Fair by Sol Bloom because it sounded salacious, would attract scandalized Victorian patrons and sell a boatload of tickets.

Toilets don't flush clockwise vs. counterclockwise as a result of being on one side of the equator or another

This fact is so engrained into our public consciousness that even shows likeThe Simpsons get it spectacularly wrong, and we've almost all had teachers cite this in class while explaining the Coriolis effect. The thing is, it's balderdash. To get a sink or toilet to drain in different directions is much more a matter of drain shape, the motion of the water when the container was filled and so on. You literally need to leave a big reservoir of water sitting for days to be able to get it to behave in a manner that's observably changed by Coriolis forces, and that's after protecting it from wind, sun, vibration, etc, and using a special drain and tub.

Diamonds can be shattered with a hammer

There is a difference between how tough something is and how hard it is.

Diamond Swords vs. Metal Swords
So as I'm assuming iron and steel are much tougher than diamond, would it be correct to say a sword made of diamond would be useless when clashing with a standard metal sword? This myth seems greatly perpetuated by many video games in which diamond weapons and armor are among the highest class.
- IkananXIII

Not as useless. The force between the two has to overcome the peak stress of the diamond sword. The metal sword would bend and the diamond sword shatter like glass.
