What I was a kid I had a strange belief about human anatomy. I knew you could see the "dangly thing" at the back of your throat. I believe it's all the uvula. I heard people cough and say that something "went down the wrong tube". For some reason I though that there were two tubes. I thought that one tube was for water and one tube was for food. Well, there are two tubes, but that's not how it works. Haha. It was interesting to finally find that out.
