In spite of all the training you get and precautions you take to keep yourself alive, it's largely a matter of luck that decided whether or not you get killed. It doesn't make any difference who you are, how tough you are, how nice a guy you might be, or how much you may know, if you happen to be at a certain spot at a certain time, you get it. I've seen guys out of one hole to a better one and get it the next minute, whereas if they'd stayed still they wouldn't have been touched. I've seen guys decide to stay in a hole instead of moving and get it. I've seen guys move and watch the hole they were in get blown up a minute later. And I've seen guys stay and watch the place to which they had intended to move get blown up. It's all luck.
