Knowing things

Generally speaking, people like to know things. The more things they know, the more they think they know. They like to be able to stand up and say, “I know all about it.” But even though it is good to know things, it’s not always good to know all things. There are some things you are really better off not knowing. Sometimes it is better not to know a thing than to know it. In fact, too much knowing of things that you need not to know can cause all sorts of problems. It can even cause your head to get overheated and catch fire.
