    Our body is made of many wonderful parts, but brain is the most amazing of all. Many things are unknown about human brain and scientists are still working hard to understand it.There are many misleading（误导的）facts about the power of the human brain.

Do you know every day we use 100% of our brain? Some think that no one uses 100% of their brain. But, in fact, we all use it completely. Every part of our brain is connected with some part of our body, and while we are still alive, we use all the parts. So our brain is fully used. But one thing we can say is that we do not use the full potential(潜能) of our brain. The human brain has more potential. For example, there is nothing in the world you cannot learn, but some give up just because they don't think they can do it. In fact, every brain is strong to learn and understand. You need to develop that untouched potential of your brain and give some more time to that work.

There are also some interesting facts you didn't know about the human brain. Our brain can't do many things at the same time. Neurons(神经细胞) in our brain work so quickly that we feel we're doing more than our task, but actually we are not. Our brain does more creativec(创造性的) work when we're tired.

Seeing positivec积极的) in others shows our positive traits(特质) ,  and seeing negative(消极的) in others shows our negative traits. Being with happy people makes happier. Happiness, anger, sadness, fear(惧怕), disgust(厌恶), and surprise are the six feelings that people all over the world show.

We are happier when we are kept busy, as this stops us from thinking about the negative things in life. Our brain makes us different from other animals and enables human to progress and grow. Just put your potential to full use and achieve (达成) the unbelievable.
