Where to Go After a Lifetime in IT?

Pikoro asks: "I have been working in the IT field for the past 20 years or so, and after getting hired by the largest financial company in the world, I thought I might have finally found a place to retire from. However, after working here for almost a year, I find myself, not exactly burnt out, but longing for a complete career field change. It's not that doing IT related tasks aren't fun anymore, but they have become more 'work' than 'play' over the last few years. Since all of my experience has been IT related, I'm not sure where I could go from here. What would you consider doing for a living, after being in a single field for so long?"
