Wow, it is an impressive list. No lawyers yet though!
Like many here, Maths, Chemistry and Physics were also in my student background all those many years ago. A love of geology eventually took over my B.Sc. at university and ever since I've been wandering the outback of this broad, brown, wide, wonderful land of ours looking for riches and (currently) digging them out of the ground.
My exposure to Civ was in no way work related for me, it developed from a general love of computer gaming, which in istelf stemmed (I think) from my old D & D days.
I'd be interested to see the results if this poll was run in the general forums rather than GOTM. I think perhaps that the competitive nature of GOTM is more inclined to appeal to the engineering/science types that most of us appear to be, rather than to people with a more liberal-arts background. My guess would be that they are all participating in the demo-games!
Cheers
