Mildly Interesting

• Contrary to what DARE might have taught you, marijuana is not considered a substantial gateway drug, with the best evidence being limited in nature, and with most marijuana users not going on to use other drugs. (Source) Yeah learn all that DARE BS.

• You were probably taught at some point that we'd never be able to map out the entire human genome due to its complexity. However, in 2003, we documented the first 92%, and in 2022 we documented the remaining 8%. (Source) nope I was told we will map it soon

• This one got shared by school nurses all around, but did you know that you shouldn't tilt your head back if you have a nosebleed? This could cause you to choke or vomit as a result of blood going back into your throat, or - more severely - trigger a vomiting reflex and cause inadvertent harm. (Source) Nope but my mom is a doctor so I leaned from a lot from her

• You were probably taught at some point that people in the time of Christopher Columbus all thought the world was flat. However, this is a myth that pervades history - most people knew the earth was a globe! (Source) Yup

• On the topic of Christopher Columbus, you might've been taught that he was a pretty upstanding guy, or at minimum just that he was average in terms of morality. Take a second to Google his relationship to slavery and genocide. (Source) EHHH kind of, we talk briefly about him mass cutting off people hands and enslaveing people.

• A common myth that gets thrown around a lot in health classes is that cracking your knuckles can cause arthritis. This, as it turns out, isn't true - it's perfectly safe to crack your knuckles as much as you'd like. (Source) Heard that in school mom said it was wrong, I heard both the myth and the fact

• The original food pyramid was introduced in 1992, and seemed to imply that there were different tiers of 'importance' to what food you ate. Since changed in 2011, this was deemed an inaccurate and potentially harmful way to view food intake. Food is food after all! (Source) Nope never learned that there where tiers of food each part is good for you

• A fun fact about taste for you - there is actually no such thing as a 'taste map,' or the idea that different areas of the tongue result in you tasting different things. At most, there's just different regions of sensitivity to taste! (Source) Nopw, saw taste map never learned that it was supposed to show where you taste things

• You've no doubt heard of this myth, perhaps not just from school - the idea that we only use 10% of our brains. This isn't true - we use all parts of our brains, just at different times since each neural location has a specific purpose! (Source) Yeah heard that

• Another common myth is the idea that Thomas Edison invented the lightbulb. He was in fact not the inventor, just someone who helped to optimize its efficiency. (Source) yeah heard that

• There's a good chance when you were younger, you heard classical music in the classroom to try and make you smarter. However, this is a myth - there is no such link between music and intelligence (or that we can measure intelligence for another matter!) (Source) Yeah heard that

• You've probably heard a lot about Thanksgiving being a supposedly peaceful gathering among Pilgrims and Indigenous Americans, but this is actually a myth - it led to a bloodbath brought on by colonial settlers. (Source) Yup heard that.
