Every action and every thought is cut down to exactly what is needed and no more. For a short period of time, the rescuer goes into a sort of trance, becoming a machine devoted entirely to the matter at hand. Nothing is sped up. That might lead to error. So everything that isn't absolutely necessary is cut out.
Every action is deliberate.
Every word is direct. Every thought is efficient. Last chance to make sure HQ knows where I am. Just trust them. I cast my radio into the sand, made sure my buoy was secure on its rope and high-stepped into the water.
