You are reading these words using input from the sensory receptors in your eyes to acquire visual signals for interpretation by your brain in concert with the output of motor systems to control eye movements required to track the words. At the same time, other components of your nervous system are managing "housekeeping" functions, including maintaining posture, breathing, and moving food through your digestive system. This is a huge task; when a body is at rest, the brain by itself is responsible for one-fifth of the body's oxygen consumption.
