I'd put Stand-Up Comedians and Auto-Mechanics in there as well. Though not 'traditionally' smart, Comedians are in a cut throat environment to see the world in a different and funny light. Mechanics, the ones not on meth or in the bottle, also need to use as many senses as possible to diagnose and cheaply fix very complicated machines with unknown histories. I have found that even the ok-to-good ones (and there are a LOT of bad comedians and mechanics) are very logical people and can easily grok any Calculus, it's just that their other personality traits (ADD, tactile needs, love of attention and 'the laugh') and circumstances move them towards their chosen fields.
