Cloudchaser: Not a pilot but know what you mean, having lived with a pilot for a few years. And even with my own job every now and then you get a reminder that you are breakable.
I once dealt with an incident where I was on my own and thought I was going to be killed... Never wanted to go to work again, let alone go out on my own, but I did and those feelings passed.. Now back to being slightly blase but I'm sure I will be given many reminders I'm not infallible before I retire !!!!
Live life to the full and it wasn't a wasted life.
