General consensus is...Go for it!
I'm typing this from about 200 miles ENE of Rio De Janeiro right now...granted, Brasil ain't Saudi Arabia, but like you, and others have said, the money is great. I'm 51, married, with kids and a grandson...don't much care for being gone 6 months a year, but you get used to it. And did I mention the money is great? Money won't buy you happiness, but it WILL afford you a whole different class of misery! Wouldn't hurt my feelings to spend the rest of my career in the oilfield overseas.
