As an exercise, I suggest you try this the next time you're out and about. At a random moment, pause and consider: without looking, do you know where your nearest exit routes are? Do you know who is around you, their approximate positions, what they are doing and what they are wearing? Are you aware of any recent changes in the situation that, mentally, should prompt you to consider if-thens? Now look around and confirm; were you right? Repeat this exercise whenever you get a chance and in time your cognitive ability and recognition of situations will improve.
