Here is an astonishing and signficant fact:Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.

So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.

Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England’s most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.

When I was six years old, my mom told me that I could find anyone's number in the phone book. I used to look through the phone book for hours trying to find Michael Jordan's phone number. When I couldn't find it, I just dialed seven numbers. When someone answered, I'd ask, "Is that Michael Jordan?" Obviously, I always had the wrong number.

A year later I started playing basketball at my local recreation center. It was very big. I never thought in my wildest dreams that a basketball court could be inside a building. The recreation center had a special smell in it, sort of like hot rubber. I guessed it was from the shoes hitting the floor so fast and hard. The atmosphere on the court was carefree. Our biggest excitement of the day was when we actually made a shot. We celebrated wins over ice cream at a fast food restaurant.

I got good at it, and my confidence grew. I played it all the time until the sixth grade. As soon as junior high school came, I stopped playing basketball and focused on school. When senior high school started, I tried out for the school team and made it. We worked hard. Every week we did 300 push-ups and 300 sit-ups on our own. Our coach encouraged the sit-ups to keep stomach power, because it gave us so much control when we were playing basketball. If we didn't want to do the sit-ups and push-ups, we could practice dribbling (????) and shooting more. It's just us, the ball, the court and the net. But don't take my word for it. See for yourself. After all, I'm just one kid playing the game.
