when i found an old book about medicine in the attic, it was so full of big words like "preceding interpretations" that i had to start from square one just to understand a tiny bit. but there was this one page, kind of hidden, like it was overlook or something, and it said that some medicines are off limits unless a doctor says it's okay. it's like a secret rule, making sure we don't take the wrong stuff and stay safe and happy!
