Whenever I go to a hotel, I always know where the stairwells are. I sometimes even count the doors to them from mine. When on a plane, I know where the exits are, how many seats are between me and the exit, and what kind of people are in those seats.
My wife is puzzled by it because that kind of thing is so far from her mind, but I developed the habit of that when I was in the Navy serving on a ship. I think I had a fear of being trapped in an emergency, so I always had an idea where the nearest hatches and exit routes were, in addition to damage control lockers, firefighting gear, etc.
I don’t worry about it, but...I do know. LOL, I also carry a flashlight with me at all times when traveling too...I guess that is kind of anal-retentive.
I carry a coffee can behind the seat in the car with a multi tool, 50 feet of parachute chord, a half dozen bic lighters a roll of toilet paper, a couple of space blankets etc.
