Once upon a time, there lived a wise man. Everyone respected him. His son, however, was very lazy and did nothing all day.
The wise man was worried about his son’s future. One day, he said to his son, “I want you to go and find some treasure. I have drawn a map to guide you.” Then he handed his son a bag. Inside the bag were clothes, some food, a little money and the map.
The son set out on his long journey the next day. He had to travel across forests, rivers and mountains. Along the way, he met a lot of people. He was helped by some with food and by some with shelter. He also came across robbers who tried to rob him. He saw changing landscapes (风景) and experienced different kinds of weather.
Finally, after a long year, he reached the treasure’s location. He spent two days looking and digging for the treasure, but found nothing.
Disappointed, he headed back to his home. On his way back, he experienced the same changing landscapes and seasons. Sometimes, he would stop to enjoy the beauty of nature. He also learned to hunt and make meals. He had to fix his own clothes and shelter himself. He was now able to tell time by the position of the sun and protect himself from wild animals. He met the same people who had helped him earlier. This time, he stayed and helped them in order to repay them.
When he reached home, he apologized to his father for not finding the treasure.
“There wasn’t any treasure in the very first place, my son,” the father answered with a smile. “But I think you have found your life’s true purpose.”

Fear may be in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting (收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain reacts to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: "Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart."
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr. Garfinkel said, "The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Thus our hearts can also affect what we see and what we don't see-and guide whether we see fear."
To further understand this relationship, the scientists also used a brain scanner (扫描仪) to show how the brain influences the way the heart changes a person's feeling of fear.
"We have found an important mechanism by which the heart and brain 'speak' to each other to change our feelings and reduce fear, "Dr. Garfinkel said.
"We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety (焦虑) disorders, and also for those who may be suffering from serious stress disorder."
