discovering the wonder of the brain

our brain is our boss. It tells us what to do. When something hurts, nerves send messages to the brain which quickly responds with a message of what you should do. Ex. you touch fire, the message through the nerves reaches the brain. the brain tells you to quickly move.
we say a model of a person. the light bulb was his brain center. When a body part had something bothering it, the brain lit up.
