Walk down a street and try to notice if a person is right handed or left handed. Some are ambidextrous so take note of that too. You can check from time to time by asking a question and offering a map for orientation. Remember another person can do the same for you and put you at a disadvantage if there is a team working. With a partner have one of you keep a folding knife in one of the pockets and walk and have the other work to find it. Have him stand and bump gently into him as you pass to try to feel it and again remember others can do the same to you. This is just an example of this type of awareness work and it all comes down to the breath. Pay attention to your breath and to the people around you and always keep looking for more. Relax; this is a life long drill.
