I'm afraid I would be quite a boring inhabitant. I'd probably be a wonderful bookkeeper... which is about the most boring job in the world except to people like me who love keeping lists, arranging data, and generally being picky about patterns and precision. In real life, I'm a psychology/engineering student with an aim to go to graduate school and design assistive technology, with a focus on research. Some of the best times of my life have been spent making Excel and various specialized statistics programs turn thousands of numbers into graphs and p-values. Sometimes I even do it for school or work.
In DF, I'd be one of those bookkeepers who just kind of stays at the desk all the time until they start flashing blue arrows, and random dwarves keep complaining that they can't bring them water because there aren't any buckets, and keep updating stockpile records even when you got to Highest Precision fifteen years ago.
Yeah, boring, to anybody but a statistics geek. But it's my kind of life. Not that I wouldn't be willing to bite the fingers off invaders if they disturbed me at my work. Do not dare touch my circles! And I won't be near as passive about it as a certain ancient mathematician. You stop me from counting on my fingers, and I will bite off your fingers, one-by one, very precisely. And then I will go back to counting blocks of microcline.
