Q: Article: They tell us when to get up or when we're running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body's own internal clock---have a powerful influence on our health and behaviour. _ are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns. In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music. The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end. "The body clock has a great effect on us all," says Professor Jim Horne from the Sleep Research Centre at Loughborough University. "Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That's because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece." So what effects do circadian rhythms have and what's the best time of day to take advantage of them?

Q: Article: A young man approached the foreman of a logging crew and asked for a job. "That depends," replied the foreman. "Let's see you fell this tree." The young man stepped forward and skillfully felled a great tree. Impressed, the foreman said, "You can start Monday." Monday, Tuesday, Wednesday, Thursday went by -- and on Thursday afternoon the foreman approached the young man and said, "You can pick up your wages on the way out today." Shocked, the young man replied, "I thought you would pay me on Friday." "Normally we do," said the foreman. "But we're letting you go today because you've fallen behind. Our daily felling charts show that you've dropped from first place on Monday to the last place today." "But I'm quite hardworking," the young man disagreed. "I am the first to arrive and the last to leave and even have worked through my coffee breaks!" The foreman thought for a minute and then asked "Have you sharpened your axe?" The young man replied, "No, sir. I've been working too hard to take time for that!" Our lives are like that. We sometimes get so busy that we don't take time to "sharpen" the axe. In today's world it seems that everyone is busier than ever, but less happy than ever. Why is that? Could it be that we have forgotten how to stay sharp? There's nothing wrong with hard work. But we shouldn't get so busy that we ignore the truly important things in life. We all need time to relax, to think, to learn and to grow. If we don't take time to sharpen the axe, we will become dull and lose our effectiveness.

Q: Article: For a long time people have believed that high self-esteem is the key to success. However, new research shows that focusing just on building self-esteem may not be helpful. In some cases, having high self-esteem can bring bad results if it makes you less likeable or more upset when you fail at something. "Forget about self-esteem," says one of the psychologists involved in the new research. "It's not the most important thing." This idea may sound a bit strange to you because studies also show that people with high self-esteem are less likely to be anxious, shy, or lonely than those with low self-esteem. In short, to feel good does you good. But, after reviewing about 18,000 studies on self-esteem, Roy Baumeister, a psychologist at Florida State University, has found that building up your self-esteem will not necessarily make you a better person. He believes that violent and evil people often have the highest self-esteem of all. He also said, "There's no evidence that kids with high self-esteem do better in school." All types of people have problems. "People with high self-esteem can have big egos that can make them less likeable to their peers," said Kathleen Vohs, a psychology professor at Columbia University. "People with high self-esteem tend to think more of themselves," Vohs says. People with low self-esteem are more likely to rely on their friends when they need help. Researchers say it is best to listen to and support other people. Find positive ways to contribute to society. If you fail at something, try to learn from the experience. The best therapy , as they suggest, is to recognize your faults, accept yourself, understand your weaknesses and then do something about them.
