Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feeling can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm, reasonable way. Others burst with anger, losing control of themselves. But still other people control their anger. They cannot or will not express it.

    For years many doctors thought that controlling one's anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain lets out the same hormones that are produced during tense situations. They speed the heart rate, raise blood pressure, and narrow the blood vessels. In general, the person feels excited and ready to act.

    Doctors said that controlling these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger too often and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.

    Some doctors say that both controlling and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

    Are you interested in students in other countries? Do they also have so much homework like you? What do they do in their spare time?

    On April 8, a report came out on the lives of high school students in China, Japan, South Korea and the US. It surveyed around 6200 students from the four countries last year. You will find the answers to many of your questions in this report.

    Who study hardest?

Chinese students spend the most time studying. Nearly half of Chinese students (48.65%) spend more than two hours on their homework every day. That's much more than students of the US (26.4%), Japan (8.2%) and South Korea (5.2%).

    Who sleep most often in class?

Japanese students fall asleep in class most often. About 45% of them said they sometimes sleep in class. In South Korea, it's 32%; in the US,21%; and 5% in China.

    Who are the most distracted?

    American students are the most active in class, but also the most distracted. 64.2% said they chat with friends in class; 46.9% said they eat snacks in class; and 38.9% said they send emails or read storybooks in class.

    What do they do after school?

    In their spare time, most Chinese students study or surf the Internet. Most American students go out to play with their friends. Most Japanese students do physical exercise. Most Korean students watch TV.

    Johnny Jennings is 86 years old, but he first visited the Georgia Baptist Children's Home when he was 18, and the visit changed his life forever.

    A child ran up to Jennings, begging to be adopted, and it was at that moment that Jennings realized his life's mission. From that day forward, Jennings did everything he could to help, and that turned out to be quite a lot. Since he wasn't ready to adopt a child of his own, he decided to contribute financially. Since he wasn't wealthy, he did so by collecting paper and aluminum (铝) products and cashing them in for money. That may not sound like it would amount to much, but Jennings has donated more than US$400,000 over the past 30 years. That's a lot of paper products.

    Over those 30 years Jennings has become a cornerstone of the children's home.

But how does he get all that paper? Now that people know about his efforts, the paper pretty much comes to him. People drop it off at his house after collecting it through churches, organizations or in their own lives. Jennings also collected pennies, and as they say: A penny saved is a penny earned. Well, he's saved 24 miles' worth of pennies. It's the truth. "84,480 is a mile of pennies," Jennings said. "We finished 24 miles. We had most people from church collecting pennies." Each and every mile was a donation to the church.

    One of Jennings' favorite events is the church's annual meeting, which is when he presents his check each year. During this time, the kids who live in the children's home are also in attendance and he loves the opportunity to spend time with them. Jennings has served on the board for 45-year terms. "I've been a trustee for 20 years," Jennings said. "I'm just part of the family." And what a special family it is, thanks in large part to Johnny Jennings.

    When it's five o'clock, people leave their office. The length of the workday, for many workers, is defined by time. They leave when the clocks tell them they're done.

    These days, the time is everywhere: not just on clocks or watches, but on cellphones and computers. That may be a bad thing, particularly at work. New research shows that clock based work schedules hinder creativity.

    Clock-timers organize their day by blocks of minutes and hours. For example: a meeting from 9 a. m. to 10 a. m, research from 10 a. m to noon, etc. On the other hand, task-timers have a list of things they want to accomplish. They work down the list, each task starts when the previous task is completed. It is said that all of us employ a mix of both these types of planning.

    What, then, are the effects of thinking about time in these different ways? Does one make us more productive? Better at the tasks at hand? Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier, they had participants organize different activities from project planning, holiday shopping, to yoga by time or to-do list to measure how they performed under "clock time" vs. " task time". They found clock timers to be more efficient(有效率的) but less happy because they felt little control over their lives. Task timers are happier and more creative, but less productive. They tend to enjoy the moment when something good is happening, and seize opportunities that come up.

    The researchers argue that task-based organizing tends to be undervalued and under-supported in the business culture. This might be a small change to the way we view work and the office, but the researchers argue that it challenges a widespread characteristic of the economy: work organized by clock time. While most people will still probably need, and be, to some extent, clock-timers, task-based timing should be used when performing a job that requires more creativity. It'll make those tasks easier, and the task-doers will be happier.
