How do you think you'd do on the ASVAB (sp?)? I think if you score high enough in the right area (i.e., linguistic ability or something), you can get a job that'll probably guarantee you're safe from most danger.
A friend of a friend of mine is an air traffic controller in the navy, seems like a great gig, and he'll be set to make a ton of money when he gets out, since civilian air traffic controllers make a ton of money.
Another friend of mine is training to be an Arabic translator (not sure if he's technically navy), and it's a great job.
So you don't necessarily have to worry about dying like everyone says. If you're SURE you want to join the military, you should do it before college, since you get your college paid for, and you can even take classes for credit while you're serving. I know a guy who earned his bachelors in management information systems while serving (relatively safely) as a computer technician in a base in Iraq. That's a pretty sweet deal - make about 40,000 a year WHILE getting a bachelors degree.
There's all sorts of ways to make the military work for you.
Definitely NOT for me, though. I think I would hate the military culture.
