Life bus

Yesterday we visited the "Life bus," we learnt all about our brain.
We learnt that the brain is about the size of our two fists together.
It controls all of our body.
Our brain is a muscle and it needs to be exercised.
Our brain sends messages to all of the body.
Messages travel along nerves.
Our longest nerve ending goes from the back of our head to the end of our big toe.
Messages can travel upto 250 miles per hour. That is 100 metres per second.
The brain is protected by the skull.
We can damage our brain by drinking alcohol or using drugs. Some boxers have damaged their brain because of the amount of times that they have been hit.
