What do you think is the most important part of the body?

I think all of the part of the body are very important. However among all of the part I think the head is the most important part of the body. Inside the head there is a brain that is important. We can think and talk and move because the brain command us. If people hurt their brain seriously they could be vegetative state so they can’t think as well as move even though they have all of the part of the body. I think we have to protect well our precious head.
