Being an expert on one small segment of European history (or whatever).....
Maybe writing a book or something... Going on "field trips" to investigate historical sites or some jazz like that....(really just drinking wine in the French countryside....).
Come back to your cozy little "Tudor" home just off campus. Ofcourse the campus would be one with lots of old buildings, lots of ivy etc. Hell, I think I might just need to take up pipe smoking since that seems it would go great while reading next to the fireplace.....(which is essentially your job, no?)
Teachin a coupla classes per day..... Talkin about a bunch of BS all day long.... Philosophizing.... Existing in a state of near immunity (hell, let's just call it bliss) from the economic realities of the real world.....

O.k. Enough is enough! Back to reality.
