I have a friend who works on an oil rig off the coast of Brazill. They fly him on and off. I think he works 10 days on, 3 weeks off? I can't remember. The hours are awful when he is on the job but the money and time off makes up for it.
There is a lot of drawbacks working on the rigs. If you are smart with your money that can be a good go. Do this for a few years then start a business.. is just an example.. Most people go for the easy stuff like buying huge homes and nice toys then got stuck with the job for years.. There is a lot of drugs and alcohol also in that game..
