| The human brain is the third largest organ in the body. It weighs an average of three pounds and is made up of fat and protein. The brain is the control center for the whole body. It has some 100 billion nerve cells and operates other organs, creates thoughts and emotions, controls movement, and gets and keeps information all at the same time. It is what makes us different from other animals. It gives us the means to use language, think rationally, sense the world, and so much more.
The brain is quite flexible and continues to develop even into old age. However, just like the muscles in our bodies, the brain needs care and regular exercise to stay fit. If we don't do this, then our control centers won't be able to make a decision, keep our fears in check, or remember anything we did.
A good way to keep the brain healthy is to challenge it with clever games and tests, like those found on National Geographic Channel's Brain Games. Each of the 12 episodes reveals more of how the brain works, so don't miss seeing any.
