Thinking ... All the while thinking. Our brain (I gather that this do not read things without brains, and that those who read it are mostly human) is an organic machine of unknown power. One thing is sure; it hasn't a pause button, stand by or glitch. It is always flowing from one thing to another... The five senses are receivers of information. Incoming data without stop flow to the brain which analyzes everything and sends replies and commands to handle the body.
