What would you call a person who moves to one place or country, stays for a few months or so and holds a job, then moves to a different country or place, gets a new job there, etc etc. I've read somewhere about a guy who was frugal with his money and moved from country to country, living in every place he wanted to travel to. And he had a job for as long as he lived there. If he got tired of the job he could quit and move to another country or new atmosphere and find a new job to learn. What would you call a person like this, a nomad, emigrate, something else? What is your opinion of this idea and would you ever consider doing it?
