It really depends
on how badly you want to vanish. Disappearing means becoming a street person or a nomad in the woods. It means to consistent bed, no constant source of income, not knowing where you're going to eat next, and all the rest. If you're living off the land, it means possibly accidentally poisoning yourself and eating things that ordinarily you would never consider.

I looked very closely at doing it about ten years ago, and in retrospect I'm glad I didn't.
