I'm not sure I really got the point here. Very few really dangerous, scary situations in life come with the opportunity to desensitize yourself and practice beforehand in a safe, controlled environment. If anything, he's got it easier in some ways! Yes, his job is much more dangerous than most things people will ever do. At the same time, he is highly trained and practiced in every aspect of his job, so that he will be well equipped to find a solution if a crisis does happen. Most of us don't get that chance!

MegaKaitouKID1412 "Which ones can't you?" There are endless unpredictable Bad Things - accidents of so many kinds, crimes committed against you, other unexpected situations that you may find yourself in with no warning and no time/opportunity to prepare. Sure, you can use common sense, be generally aware of your surroundings, and think ahead in general terms, but that's not the same as suddenly being thrust into, say, a terrible car accident where you're trapped or your kids are trapped and you have to figure out on the spot what to do. That's quite different than going through the sort of training that astronauts have to endure, where every possible problem is simulated in a controlled environment so that they can learn to troubleshoot (as well as to not panic!) so that they will be as prepared as they can be should they face the real thing. Real life doesn't often offer that sort of testing. It just doesn't.
