I can tell you why people do this. My "job" isn't really a job, it is a calling. It is physically demanding at times, required a lot of training, is dangerous and really doesn't prepare me to step out into the civilian world and into a high paying civilian occupation. I get a lot of satisfaction out of what I do and no amount of money is worth the way I feel. I also get a real kick out of it. Don't pity me for what I do or what I get paid because I made the choice to stick with what I do. To be honest I sometimes pity the people I see driving to work every morning, doing the same thing day in and day out, because every once in a while I get to do something really cool like save a persons life, or I get the crap scared out of me and it reminds me that I am alive and have a lot to be thankful for.
