Avoid falling off stairs (8/9)

If your gait is too static, and most of the time you keep your hands in your pockets, we have bad news for you. This is a terrible way to walk, because the nature of your body requires balancing with the swing of your hands, especially if you are going up or down some stairs, if you stumble and your hands are stuck in the pockets of your pants, they will not be able to come out to defend you from the encounter with the ground.
