Justin Bieber used to be an ordinary Canadian boy, but his life totally changed in 2008. With his great musical talent, this seventeen-year-old boy has become a superstar in the music industry.

    Justin Drew Bieber was born in 1994 in Stratford, Ontario and was raised by his single mother. Bieber learned to play musical instruments when he was very young. In 2007, he took part in a local singing competition in his hometown, and he did it just for fun. He never took singing lessons before but surprisingly he placed second in the competition. Then, with the help of his mother, he uploaded (上传) videos of him singing on a website and they successfully attracted the attention of thousands of viewers. His videos got popular through word of mouth and some of them have received up to 10,000,000 views.

    Justin Bieber would have never gotten a career in the music business without his videos. Scooter Braun, a former marketing executive (主管) of So So Def Recordings, had watched Bieber's videos and he was impressed by the boy's talent. Braun then contacted Bieber and he flew the boy into Atlanta seven months after the first video was posted. Bieber showed his talent in singing as well as his ability in playing musical instruments. He then got a record deal.

    In 2009, Justin Bieber released (发行) his first single “One Time” while he was recording the debut album (首张专辑). The single “One Time” tells a story about love. This song had success not only in Canada and the US, but also in the international market. Then he released his debut album “My World 2.0” in 2010 and the song “Baby” became the lead single. This album successfully entered the Top Ten Charts in seven countries. In June 2010, he started his first world tour in Hartford, Connecticut. One month later, he started recording his second album.

    It is said that if you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise — and as a result, we are growing old unnecessarily soon.

    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side parts of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual on economical faculties. Contraction of front and side parts — as cells die off — was observed in some subjects in their thirties, but it was still not evident in some sixty-and seventy-year-olds. Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected with age — using the head.

    The findings show in general terms that contraction of the brain begins sooner in people in the country than in the town. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as the farm worker, bus driver and shop assistant.

    Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain, good blood circulation is through using the brain.” he says. “Think hard and engage in conversation. Don't rely on pocket calculators.”

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    It is widely acknowledged that nearly every kid might come across some kind of school bullying(欺侮), however, the age at which kids were first bullied could influence how strongly they are affected, suggests a new study. And, surprisingly, it is not the youngest kids who are hurt the most in the long term.

    Bullying can have long-lasting effects, but particularly when it begins in adolescence(青春期), the researchers say, people subjected to either verbal or physical bullying are known to be at greater risk of developing depression, anxiety disorders or to behave violently. But not everyone reacts in this way.

    Children who were bullied for the first time before they hit adolescence seem to get over it, but those who are bullied for the first time later on in adolescence seem to become more aggressive(富有攻击性的) or are more likely to turn to drinking as a means of coping with it. These are the conclusions of psychologists Matthew Newman and colleagues of Texas at Austin, US.

    The team gave questionnaires to nearly 1,500 college students about their experience of physical and psychological bullying before adolescence- before high school- and in late adolescence- at high school. They assessed mood and mental state, judging by signs of anxiety or depression, such as sleeplessness. The group was also questioned about how they would react to certain challenges, such as humiliation.

    People who were bullied all showed slightly higher levels of stress. But while those bullied earlier in life seemed to respond normally to provocation (煽动), people bullied for the first time late in adolescence are more withdrawn and sensitive to violence.

    There are also sex differences between those bullied for the first time during adolescence: females are more likely to react aggressively when provoked and males are much more likely to turn to drinking to escape bad situations. The best solution in all cases was strong social support, whether from friends, family or school. Those with no one to share their problems with suffered the most.

    So perhaps it is best not to shelter children completely from bullying early on, suggests Newman, "They may get stressed, but unhealthy coping really jumps out when they are bullied for the first time later on."

    Forest Schools originated in Sweden in the 1950s and spread to other countries, particularly Denmark where they have become an important part of the Danish early years program.

    In a typical Danish Forest School, young children from 3 years are taken into the forest for 4 hours each day of the week. They take no toys with them, but instead use only what the forest provides (and their imaginations) to develop their games. There is a primitive hut in the forest, which is used in extreme weather. Activities are child-led and fun, such as finding small animals or stomping in puddles. Because of high adult to child ratios, children can safely try out activities which are often considered too dangerous, such as climbing trees or lighting fires, and by dressing the children in good protective clothing, they are able to play freely. By setting children small manageable tasks at which they are unlikely to fail, and giving genuine praise, children's independence and confidence grow.

    A Swedish scientific study found that children in the Forest School are more balanced and socially capable, have fewer sick days, are more able to concentrate and have better co-ordination than the city nursery children. The primary reason appeared to be the greater opportunities to play in nature, so that children play for longer at a time, tending not to disturb each other as much as children in the city nursery. The study observed that where children were interrupted, they became irritable, their stress level rose, and their ability to concentrate fell.

    The study also showed that the Forest School children had 25 % fewer sick days than the city children. One reason for this is that the air is nearly always better outside than indoors. Outside a child is not so exposed to virus and bacteria and not so likely to be infected by other children. Another reason may be that, since stress has been shown to have a negative effect on the immune system, high stress levels may be weakening the city children. The Forest School children, on the other hand, are in a pleasant, natural, fun and less stressful environment.

    A traditional Chinese cough syrup (糖浆), called Nin Jiom Pei Pa Koa (念慈庵川贝枇杷膏), is flying off the shelves in New York stores this flu season, following a US news report.

    According to a report in The Wall Street Journal last week, Mr. Alex Schweder, a professor of design at Pratt Institute suffering a cough for about 10 days, felt better 15 minutes after he drank a bottle of Nin Jiom Pei Pa Koa. It had been recommended by his girlfriend, who first learnt about the cough syrup 30 years ago when she was living in Hong Kong.

    Mr. Schweder was shocked by the magical effects of the cough syrup, and recommended it to many people. This, together with other factors, soon made the Chinese medicine popular in New York City.

    A 300ml bottle is now sold at US$13.29 on Walmart's website. This is more than double the former price in some pharmacies (药店) in Manhattan's Chinatown, selling at about US$6 per bottle. "The number of Nin Jiom Pei Pa Koa we sold over the past few days was much more than usual," said Winnie, a sales staff member of Buy-rite pharmacy in Chinatown. "More and more Westerners are accepting this medicine because it is effective," she said.

    According to the Kingworld Medicines Group's official website, Nin Jiom Pei Pa Koa is made of "valuable Chinese herbs and honey, and has surprising effects in treating coughs." However, experts warn that taking the cough syrup can carry health risks, including when it is used with other medicines, used too much or taken instead of prescription medication (处方药).

    Dr. Keith Brenner, a specialist in pulmonary medicine at Columbia University Medical Centre New York Presbyterian Hospital, said, "I think people who use these things may not even tell the doctor about them, and it's a problem."
