I can honoestly say that I can tell you how just about everything works. I may not be able to do it off the top of my head, but if you let me take it apart or gave me a diagram, I would get the jist of it. Have you ever tried to imagine how everyone else lives? Most of the /. users have the same capabilities that I have. Just riding the bus to and from campus or even walking around the liberal arts campus give me a dose of the stupidity that inhabits the world.
