Is it normal to enter a place and look for escape methods?
My boyfriend has a background in martial arts and is a body builder/fitness trainer. However I don't know if that has to do with one habit of his. Whenever we enter a building or location, he becomes quiet and more focused looking, seeing his surroundings. He tells me that he looks around for the best escape route/plan; as in not just typical exits but also Windows or balconies/etc.
Is this a normal thing to do at a new environment? I don't do it personally besides looking for bathrooms, typical exit signs, cameras. He apparently does it for those AND much more. I don't think it's paranoia, but possibly a survival instinct that runs deep in him (he says that he needs to know in order to save his ass). Also, he's no criminal. Not sure about this habit though. Can anyone relate?
