I'm curious how those like you who are extremely intelligent feel about teaching, specifically topics which are very rudimentary to you, and whether this bores you to death or provides you with any enjoyment or sense of fulfillment?

I'm a decidedly not smart person, but through some good fortune I work with some extremely smart people. I work in aerospace as a technician and many of my coworkers are Engineering/CompSci/Math/Physics people. I frequently pester them with all sorts of questions that to them must be very mundane. Unless they are really good at humoring me, which is entirely possible, I get the feeling that many of them genuinely enjoy explaining things, even when they have to dumb it down, to me.
