I work in the pharmaceutical industry creating and maintaining databases to store and analyze clinical trial information.
Sounds more exciting that it really is.
Before that, I was a IT Support type dude at the university, a building facilities/events worker (setup tables and chairs for functions), a grocery store store accountant, a landscape worker (yes I did dig ditches), a bicycle repairman, a busboy at a restaurant, a school tutor... what else... I can't remember anymore.
