Better still there were a bunch of facts that were false when they were taught to you but for some reason were still taught to you.

Like the obvious one, the tongue doesn’t actually have different regions on it for tasting different things, a fact that you probably didn’t believe even back then because anyone with a sugar cube and 5 minutes can disprove that.

Some classics:

• lactic acid buildup makes your muscles hurt after a workout
• blood that’s returning to the heart and lungs is blue, blood that’s leaving your heart to go do it’s thing is red
• sugar makes kids hyper

All three of those things have been thoroughly debunked, and are demonstrably false, and yet we teach them all the time. Sometimes it’s even SCIENCE TEACHERS that are repeating these things, and sometimes it’s right in the textbook!

Don’t forget how chocolate, even in tiny amount, will kill a dog. My mother told this to my kids, and they were all confused because our dog ate a bunch of chocolate easter candy and she was fine.
