20 classroom 'facts' we learned that weren't actually true at all
Who remembers tongue taste maps?

Look, teachers aren't perfect.
Education has certainly changed over the years, and is continuously evolving. That goes for teaching methods—utilizing more technology, providing more resources to students with special needs, and incorporating more personalized approaches—as well as what information is actually being taught in classrooms.
Surely, if you think back to your childhood, you'll remember certain "facts" being drilled by your teacher that nowadays seem like straight up nonsense. And if not, you can copy off of the Reddit community's homework.
Redditor u/authorized_join31 recently asked "What’s a fact that was taught in school that’s been disproven in your lifetime?" and people did not disappoint with their answers.
Of course, while many of these are harmless fun, it's easy to see how very problematic others are. Particularly when it comes to health and history—diet fads, medical myths, falsely idolizing historical figures to perpetuate a skewed narrative…you get the picture.
If anything, these anecdotes just go to show that we should never stop trying to learn, even after school if over.
And with that, class is now in session.
1."That strangers will give me free drugs on street corners and on Halloween candy."
2. "All fat was bad for you. Thus, fat-free foods became a thing for a while."

3. "I learned about tongue taste maps at school. Turns out it’s complete nonsense."

If this were true, I'd only be using the "sweet taste" portion of my tongue.
4. "In pharmacy school around the turn of the century, we were taught that people in legitimate pain don't get addicted to opiates and opioids."

5. "Your permanent record will follow you into adulthood."
6. "The whole 'A meteorite killed the dinosaurs' thing wasn't yet the accepted theory when I was a kid."

7. “No one is going to wait for you to look up information in the real world, you have to know it.”

8. "That George Washington’s teeth were made of wood."
A brilliant example of an inaccurate piece of history that was completely injected onto our consciousness during school, that perhaps covered up a more difficult truth to swallow. In truth, Washington's dentures were made of materials from lead-tin, copper and silver alloy, as well as cow, horse and human teeth. The latter of which were bought from slaves, or at least a portion of them. That might have been more pertinent to know.
But what's even more baffling is why this false fact was so important to teach in the first place. And is we must talk about a dead president's teeth, why not tell the more exciting (and true) story of how Washington's dental trouble helped mislead the British Army in 1781? But I digress.
9. "The Food Pyramid."
10. "Once you get to high school, nobody will accept papers not written in cursive."

Algebra was a complete waste of time for some of us.

12. "I once asked one of my elementary school teachers what a rainbow was, and she told me scientists hadn't figured it out. I walked around until my early 20s thinking that. Also, I think it was this same teacher who told me Columbus thought the Earth was flat. They were training teachers a different kind of way in the '70s and '80s. It's honestly one of the reasons I'm thankful for the internet, because depending on your teacher or an outdated encyclopedia for answers could be a real roll of the dice."
13. "So many professions that we were taught were ‘lesser-than’ or just looked down upon. Being a plumber was always a joke… wish I woulda took the 70k, Union job with excellent benefits and a pension joke at 20 years old lol."
14. "You only use 10% of your brain each day."
15. "My primary school teacher told me our bodies can't make new blood and we're born with all the blood we'll ever have. As someone who got nosebleeds, I knew it was bollocks. When I questioned that adults are obviously bigger so have more blood, she said it's watered down."

16. "Carrots are good for night vision.This was a lie the British used to explain how they could spot German bombers during WWII. The truth, that they had broken the German Enigma machine and were decoding secret messages, was kept a secret for decades. The full story was not told until the 1990s."

17. "That we would all but run out of oil by the year 2000."
—u/fatbongo
18. "That lemmings commit suicide."
19. "That Canada didn’t ever have slaves. What's worse is, to my knowledge, they still don’t teach this. I had to look it up myself."
And last but not least....
20. "If you study well and have excellent grades, you will end up with a nice job and lots of money."

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
