Do I need to be available 24 hours a day?

Q. Do I need to be available 24 hours a day by some electronic means or other? It seems like everybody else is. Uncertain in WY

A. I would say that unless you are expecting a heart transplant or are a member of the Secret Service, probably not. The fact that these people look like idiots walking around with rectangles stuck to the sides of their heads are a tip off that they are not people you would want to emulate.

We have begun to think that if for one instant we aren't available to share our vast knowledge or be ready to answer the burning questions of the Universe, the world as we know it will end. Or - have we all just grown panicked at the thought of sitting quietly, alone, with one's thoughts - if we had any.
