Article: People like to look in the mirror often when they have a young and beautiful face. However, when one grows old, nobody wants to see their wrinkled old face in the mirror any more. So, many old people seldom look at their faces in the mirror. This is completely wrong. According to Wu Zhenyun, a professor from the Psychological Research Institute under the Chinese Academy of Sciences, a person's willingness to look in the mirror can reflect his or her mentality. When people don't care too much about their age, they will try to carry themselves with ease and natural poise . They don't mind looking in the mirror to see their own faces. Some people even love to look in the mirror from time to time to see whether they keep a good appearance. In this way, mirror becomes their best friend that help them to look confident. On the other hand, some people are afraid of being old. They don't want to see the wrinkles on their face and their hair turning grey. So they don't want to look in the mirror. This actually reflects a negative attitude they hold towards life. In the long term, they might suffer from psychological pressure or some sort of depression, which is actually not a wise act. " Everyone can make themselves look charming at every age stage. If one is confident, one will always look beautiful, it shows that they accept themselves." professor Wu said. Mirror cannot only give confidence to one. By looking in the mirror, one can even find the traces of some diseases from one's own face.

Article: A teddy bear from Cumbria is launching into space to raise cash for charity . Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation legend Burt Rutan's Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off in aid of the North Air Ambulance Appeal . Spaceship One is the world's first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said "flying officer" Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since. He said, "Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed--we just hope he does not burn up on re-entry to Earth." GNAAS, which needs charitable donations of more than PS2m a year, has three air ambulances . Peter Bond, spokesman for the Royal Astronomical Society, said Terence's safety was not guaranteed. He said, "This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved." Since May, Terence has spent time with members of 100 Squadron based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes. Spaceship One will fly 100km (62 miles) above the Earth's surface, just breaking through the planet's atmosphere. If it repeats the feat inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.

Article: ONE day my 5-year-old daughter, Mini, ran to the window crying: "A Cabuliwallah ! A Cabuliwallah!" In the street below was a Cabuliwallah, passing slowly along. Mini called him loudly but when he looked at her she ran away scared. Shortly after this, the two became friends. They started to hang out together, laughing and talking. Mini's new friend would give her raisins and almonds , spending the little money he had on her. The two of them enjoyed joking together. The Cabuliwallah, who was called Rahmun, would say: "Well, little one, when are you going to the father-in-law's house?" Mini did not understand this and was puzzled. One morning, I heard uproar in the street, and saw Rahmun being led away by the police. There were bloodstains on his clothes. I gathered that a neighbor had owed Rahmun money for a shawl but had falsely denied having bought it, and that in the course of the quarrel Rahmun had struck him. On a charge of murderous assault , Rahmun was sentenced to jail. Time passed, and he was not remembered. Mini grew up and we were making arrangements for her wedding. I was sitting in my study when someone entered. It was Rahmun, the Cabuliwallah, released from prison. Barely recognizable now, he asked to see Mini and said that all those years ago she had reminded him of his own daughter in Kabul. It was his belief that Mini was still the same. He had pictured her running to him calling "Cabuliwallah!". He had imagined that they would laugh and talk together. In fact, he had brought her, wrapped up in paper, a few almonds and grapes. The two were reunited but Mini had grown up. She now understood the meaning of the word "father-in-law," and when he made this joke once more she flushed up at the question. He could not revive their old friendship. When Rahmun left, I gave him a bank note, saying: "Go back to your own daughter, and may the happiness of your meeting bring good fortune to my child!" Having made this present, I had to give up the electric lights and the military band I had intended for the wedding and the ladies in the house were disappointed. But to me the wedding feast was all the brighter for the thought that in a distant land a long-lost father met again with his child. Adapted from Tagore's short novel The Cabuliwallah
