    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.

      First thing I did when I read that was to put rub something all over my tongue just as a sanity check. When I tried to tell someone they went bonkers trying to defend the school book. From that point on I never took anything school books or adults said as fact without evidence.

      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.

          Dogs, and cats although they’re unlikely to actually eat it, cannot eat artificial sweetener as their livers cannot break it down and it becomes toxic to them in moderate quantities. It is often used in a lot of cheaper chocolate, particularly American chocolate. Sugar’s fine though, other than the obvious issues with it.

          Somehow dogs cannot eat large amounts of artificial sweetener, got changed into dogs cannot eat small amounts of sugar.

            I thought the problem with chocolate is theobromine, same effect as you describe, but bitter and comes from cocoa, so less sweet / more expensive chocolate with higher amount of cocoa is actually more dangerous.

            But still, as with any poison, the dose is important, this veterinary page says “One ounce of milk chocolate per pound of body weight is a potentially lethal dose in dogs”, so a dog would need to eat 1/16th of its own weight for it to be deadly, even for small dogs that’s more than a whole bar.
