Skysue, never forget that we academics are very good at SOUNDING like we know everything LOL! It's all a crock... something I only discovered when I became a professor and realized that people with PhDs know a lot about SOMETHING, but not necessarily a lot about more than one small area. Not to belittle my colleagues and myself, we are knowledgeable in our area of research... but people seem to think that when you have an advanced degree you are better or smarter than the general population... SO NOT TRUE! It just meant we had the time, resources, and desire to study something.
