Go outside and go to a place filled with people like a shopping center or a library. Start a conversation with a stranger and while you talk to him on (the weather, the book you want to buy, the local rugby team…) keep your eyes open to look all around note how you can move naturally to get a view of all around you without looking like you are doing this and repeat the drill in another location minding your surrounding such as big reflecting surfaces, high fences, side doors and so on. Survival is about not being where it is not safe. The odds are better that way and you don’t have to be the fastest.
