Person Asks Others To Share What Widely Accepted Facts They Know Are Wrong, And Here Are 30 Of The Most Interesting Responses

The British have worse teeth than Americans. Brits have fewer missing teeth on average, and the DMFT index is 0.8 for Brits but higher at 1.2 for the United States.

That you have to buy new razor blades every week or 2. Razors dont dull because use, they dull because they rust, if you thoroughly dry them or oil them they can last for almost a year and still work just fine. This is coming from a bald guy who shaves his head every other day.

That the Great Wall of China can be seen from space.

According to NASA, you can't see the Great Wall of China from space without any visual aids. "It certainly isn't visible from the Moon," NASA writes. The theory that you could see the wall from space was shaken when Chinese astronaut Yang Liwei admitted he couldn't see the structure.

That if you have a cold, you should get lots of Vitamin C. This is completely down to one scientist named Linus Pauling who had a theory that massive doses of Vitamin C would cure colds. Subsequent studies have shown he was wrong and any benefits are minimal at best. Yet I still get everyone telling me to drink orange juice whenever I get a sniffle.

However, Harvard Health Publishing states that taking at least 200 mg of vitamin C each day seemed to reduce the duration of cold symptoms by around 8 percent in adults and 14 percent in kids. Or, in other words, around one less day of being ill. While it doesn't seem like a lot, it could have a huge effect nationwide or worldwide.

The idea that chloroform quickly knocks you out. In the real world, it takes several minutes to knock you out, not the seconds you see in TV and movies.

How quickly you're knocked out depends on your bodyweight, air circulation, the strength of the solution, etc. You'll stay knocked out by the chloroform for as long as you're breathing it. Once it's removed, however, recovering from the effects can take roughly 20 to 30 minutes during which you will feel nauseous and might even vomit. Headaches can last hours.

That if you swallow gum, it stays in your stomach for seven years. Not true. Your body processes it, and you poop it out just like anything else.

It can take up to 7 days for the body to pass through your system. However, swallowing gum still isn't a good idea because it can cause constipation, gas, abdominal pain, diarrhea, and even mouth ulcers.

That Einstein failed math/was otherwise a poor student.

Napoleon wasn't small. He was just the victim of good propaganda by the eventual winners.

Napoleon was most likely around average height: 1.69 meters or just over 5’5”. The myth that Napoleon was short comes from two sources. First of all, the French inch (pouce) at the time was 2.7 centimeters while the Imperial inch was just 2.54 centimeters. So using the French measurement system of the time, Napoleon was 5’2” (aka '5 pieds 2 pouces') tall which is equal to the 'normal' 5’5”. Secondly, British cartoonist James Gillray was very much responsible for depicting Napoleon as being tiny leader prone to rage and the image stuck in the public's mind.
