    Ever see a blood draw? Blood comes out of a vein, into a non-O2 environment.

    I think we just don’t do as much critical introspection as we like to think. Its easier to imagine maybe there was a tiny amount of O2 or something than that the thing we were taught was entirely false.

      I think we just don’t do as much critical introspection as we like to think.

      It’s definitely true, and it shows that the stuff you learn as kids is even more ingrained than we even notice most of the time. Kids don’t normally have blood drawn, so it’s not like elementary schools were filled with a bunch of kids saying “wait a minute, that didn’t happen with my last blood draw.”

        There were actually about 5 of us that contested it and she tried to say “they drew that blood from your arteries”
