I have a decent size reservoir of academic knowledge. I have a lot of expertise that goes unused at my job. If I changed jobs (the number of times of which is something I'm trying to minimize), I could probably use more of what I know. That being said, there's this PhD that I work under. I have a broad idea of what he knows, and a general idea of what he does at his job. I'm nearly certain that much of what he knows also goes unused, although his job relates more strongly to his area of expertise....so he seems to be in the same boat as me, although he probably makes much much more that me, which would be a good perk.
