Jim, I have to say if I need a question researched or an answer, Freepers usually come up with not one, but a dozen sources in less than 20 minutes. Almost any of us who have posted here for over 5 years know that you can't get away with anything---that someone is actually in the profession or line of work or endeavor of science that you are commenting on and will call you on it instantly.
Course, if you write off the cuff as I frequently do, that can be a problem . . . .
