our brain is like a message center. Each second,the brain receives more than a million messages from our body and knows what to do with them. People think that the weight of the brain tells how intelligent you are, but this isn't true. Albert Einstein's brain weighed 1375 grams, but less intelligent people may have heavier brains. What is important is the quality of the brain.
The brain has two halves-the right brain and the left brain. Each haft is about the same size.
The right haft controls the left side of the body, and the left haft controls the right side of the body. One haft is usually stronger than the other. One haft of the brain becomes stronger when you are a child and usually stays the stronger haft for the rest of your lift.
