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

Some scientists declare that most of our fatigue comes from our mental and emotional(情绪的) 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 sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired Joy Satisfaction No! A feeling of being bored, anger, anxiety, tenseness, worry, a feeling of not being appreciated---those are the emotions that tire sitting workers. Hard work by itself seldom causes fatigue. We get tired because our emotions produce nervousness in the body.

What is the hottest topic at your school recently? In Taiyuan No. 55 Middle School, it’s money.

The school held an activity called “making money” last weekend. About 200 Junior 1 and Junior 2 students were divided into 30 teams. They went out to make money by selling things.

What did they choose to sell? Some sold newspapers; some chose bottled water; some sold environmentally friendly shopping bags and bamboo baskets.

Hu Qing’s team decided to sell some useful books in front of the Children Activity Center. They thought parents would like to buy the books for their children. But unfortunately, they met urban management officers (城管). The officers asked them to leave. “We played hide-and-seek (捉迷藏) with the officers for the whole morning” said Hu. “Finally we had to give up.”

Wang Bing and her team sold ice cream in a square. They didn’t meet any officers. But few people were interested in what they were selling. The team then put up a board saying “For Country Kids”. It worked. More people came to their stall (小摊). A foreigner even gave them 100 yuan. “He didn’t want any change. He said he wanted to help the children,” said Wang. “We were touched.” Later that day they gave the 100 yuan and more to the “Project Hope” office.

Meng Zhaoxiang and his team were luckier. They sold all their cakes in four hours, spending 39.5 yuan and getting back 80 yuan. They made 40.5 yuan. “It was not easy to make the money,” said Meng. “Some people just looked. Others just tasted but didn’t buy. Now I know how hard it is for our parents to make the money we need to lead happy lives.”
