About 70 scientists were working on a very busy project. All of them felt really desperate due to the pressure of work and the demands of their boss but everyone was loyal to him and did not think of quitting their job.

    One day, one scientist came to his boss and told him, “Sir, I've promised to take my children to the exhibition going on in our township so I want to leave at 5:30 p. m.” His boss replied, “OK. You're permitted to leave the office early today.”

    The scientist started working. He continued his work after lunch. As usual, he got involved to such an extent that he looked at his watch only when he felt he was close to completion. The time was 8:30 p. m. suddenly he remembered his promise to the children. He looked for his boss but he was not there. Having told him in the morning himself, he closed everything and left for home. Deep within himself, he was feeling guilty for having disappointed his children. He reached home. The children were not there. His wife alone was sitting in the hall and reading magazines. The situation was explosive; any talk would boomerang on him. His wife asked him, “Would you like to have coffee or shall I straight away serve dinner if you are hungry?” The man replied, “If you would like to have coffee, I too will have but what about the children?” His wife replied, “You don't know? Your boss came here at 5:15 p. m. and has taken them to the exhibition.”

    What had really happened was the boss who gave him permission was observing him working seriously at 5:00 p. m. He thought to himself: this person will not leave the work, but he's promised to take his children to the exhibition. So he took the lead in taking them there. The boss does not have to do it every time. But once it's done, loyalty is established.

    That is why all the scientists at Thumba continued to work under their boss even though the stress was extraordinarily huge. By the way, can you boldly guess who the boss was? He was none other than the mastermind behind India's successful nuclear weapons program, Dr. APJ Abdul Kalam, former president of India.

     "You see someone just sitting there, looking like they're stupid," explains teenager Manny Logan excitedly. "You just run up to them, slap(掌击) them and run off. It's funny."

    The 16-year-old Logan was describing "happy slapping". It's supposed to be fun but it's a new problem in Britain. Young people will attack passers-by while their friends record the whole thing on camera phones. It was first reported in south London six months ago. But, the practice has spread to other parts of the country and videos of attacks have become popular on the Internet.

    The young people are called "hoodies" because they usually wear a sweatshirt with a hooded top. The top can be used to cover the head or face.

    One study in England published earlier this year suggested that as many as one in four teenagers is an active offender. That includes both serious crimes and small acts like not paying for a bus ticket.

    The fear of youth crime has left some parts of towns empty of ordinary people.

    So, the British government declared war on public disorder last week. The Prime Minister has supported a decision by the country's biggest shopping centre in southeast of England to ban teenagers wearing hooded tops. The clothing helps troublemakers hide from the centre's cameras.

    This week, the government is going further. It plans to force teenage offenders to wear orange jackets while they do public service. The idea is to shame them in front of others.

    But some teenagers and experts have complained that, in their rush to stop the hoodies, politicians risk tarring all teenagers with the same brush.

    When I was 10 years old, I tried out for the cheerleading squad. I had taken gymnastics classes for two years to prepare for these tryouts. However, I didn't make the team. It was a heavy blow to me. I cried all night.

    Kids today won't experience that kind of rejection. They're growing up in “everybody gets a turn” world where every child gets a chance to kick the ball, sing the song, and win the award. But that's not always such a good thing.

    Parents have become fearful of letting kids fail, thinking that our children are easily hurt and will never recover from anything—that's a serious problem. Last week, my 7-year-old daughter didn't get into the school play. At first, I was upset by it. How would she react? When I gave her the news, I was ready to hug her and cry with her. She looked at me, made a slight face and said, “That's too bad. What's for dinner?”

    It clearly wasn't the end of her world. Maybe if we let our kids experience rejection once in a while, we'd realize they are much stronger than we think. Kids need to be able to handle disappointments; doing so helps them to prepare for real life. Most importantly, rejection carries the possibility not only for growth and can also motivate kids to try harder the next time.

    Rejection is pain. There is no way around that. How will our kids ever discover their true talents if we don't let them? Instead of complaining, maybe we should consider rejection an opportunity.

    Teenagers who spend hours in front of the television may have a poorer diet as young adults.

    A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?

    On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.

    On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

    Lead researcher Dr. Daheia J. Barr-Anderson, of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who'd watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.

    As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

    Try this: For an entire day, forget about the clock. Eat when you're hungry and sleep when you're tired. What do you think will happen?

    You may be surprised to find that your day is much like most other days. You'll probably get hungry when you normally eat and tired when you normally sleep. Even though you don't know what time it is, your body does. These patterns of daily life are called circadian rhythms(生理节奏), and they are more than just habits. Inside our bodies are several clocklike systems that follow a roughly 24-hour cycle. Throughout the day and night, our inner clocks direct changes in temperature, body chemicals, hunger, sleepiness and more.

    Everyone's rhythms are different, which is why you might like to stay up late while your sister always wants to go to bed early. But on the whole, everyone is programmed to feel tired at night and energetic during the day. Learning about our body clocks may help scientists understand why problems arise when we act out of step with our circadian rhythms. For example, traveling across time zones can make people wake up in the middle of the night. Regularly staying up late can make kids do worse in tests.

    "There is a growing sense that when we eat and when we sleep are important parts of how healthy we are," says Steven Shea, director of the Sleep Disorders Program at Brigham and Women's Hospital in Boston.

    One way to learn about how our body clocks tick is to mess them up and see what happens. That's what neurologist(神经病学家)Frank Scheer and his workmates did in a recent study. Staying up night after night, their studies suggest, could make kids extra hungry and more likely to gain weight. And regularly sleeping too little, Scheer says, may be one cause of the recent increase in childhood obesity.

    What is the number one favorite pet in the UK? If you think the answer is dogs, you are wrong. There are 8.6 million cats and 8.3 million dogs in Britain according to recent figures. But experts predict that there will be more dogs than cats next year as dogs become more and more popular.

    Dogs as decorations

    We like to spend time with our pets. The Queen is famous for her affection for dogs and is often photographed with them. Nowadays some dog owners are more extreme — a few TV celebrities even take their dogs shopping or to restaurants. Chihuahuas are especially popular as "handbag dogs" because they are so tiny.

    Dog holidays

    People are also giving their pets holidays. Many UK hotels and holiday parks now welcome dogs as guests. What about owners who go abroad? They can leave their pets at a dog hotel or dog spa while they are away. Some even provide their dog guests with a TV.

    Dogs are for life

    The British charity, Dogs Trust, finds homes for thousands of lost and abandoned dogs every year. Their famous slogan "A dog is for life and not just for Christmas" was created in the 1970s to teach people about the responsibility of owning a dog. Dogs Trust told British people not to give dogs as gifts or treat them like toys.

    Dogs on TV

    Victoria Sitwell is the host of the popular TV programme called "It's me or the dog". In the show Victoria helps dog owners with their pets' bad behaviour. She tries to find solutions to problems such as a Dalmatian who thinks he owns the house and won't let the family sit on the sofa, dogs that will only eat ice cream and biscuits and even a bulldog who uses the owner's bed as a toilet.

    Fashion for dogs

    You can shop online or on the high street for the latest in dog clothes and accessories. Specialist shops sell items such as dog boots, dog fancy dress costumes, dog coats, dog dresses and dog pants.
