This actually is pretty close to what I did do to make a chunk of money. Worked as a contractor in a war zone for 3 years making about $200k a year. It feels like a prison at times. You are stuck in a walled compound with guards, guns, gates, concertina wire, people trying to kill you, terrible food, sleeping on a cot, and can't leave that compound for 8-12 months. Little connection with the outside world, days are repetitive, and nothing fun to do beyond same activities a prisoner has; reading, movies, exercise. So I guess my answer was...yes?
