It is ingrained. Maybe it was my upbringing? Maybe it was the familiarity with the Marines and then joining and serving myself? If I hear gunfire, I move towards the sound. Don't get me wrong, every instinct says to turn tail and run away! But, I run to help - or at least see what the hubbub is about. (That's just an example. I don't actually hear unknown gunfire. If I hear gunfire, it's a neighbor or someone hunting.) If I see an accident, I stop to help - unless there are already a ton of people there. I'll stand there for hours, in the cold and ice, directing traffic. I used to be on the volunteer search and rescue crew. I taught 'em to use ropes properly for rescue purposes, for example. (I can't now, now I have a smashed femur. I am of no help to them except coordination.) I run to help, not run away. Hell, I'll stop and help old ladies load their groceries into their car.
