Why do you need your brain?

Your brain is the control centre of your body. It controls everything you do - it makes your heart beat and your muscles move. Your eye's and ears send signals to your brain and it interprets these things as sight and sound. It is also where you think and store memories. If you never thought and didn't have any memories you would not be you - you would just be a bag full of bones and blood and other icky stuff. Without your brain you wouldn't be able to live and you wouldn't be a person.
