Well, or you could join the Navy, bust arse for several years till you were tapped for the SEALS, survive Hell Week, and then the HARD training
begins.
...or you could join the Marines as a grunt. Either one would teach you how to survive in some god-awful circumstances. Of course, the downside is
that it's at least a 4-year course, and lately, more like a 6 year course. And there's a pretty good chance you'll die, but I hear the fringe
benefits are great.
But they do pay you to take the class.
