Most damagingly, anger weakens a person's ability to think clearly and keep control over his behaviour. The angry person loses objectivity in evaluating the emotional significance of the person or situation that arouses his anger.

    Not everyone experiences anger in the same way; what angers one person may amuse another. The specific expression of anger also differs from person to person based on biological and cultural forces. In contemporary culture, physical expressions of anger are generally considered too socially harmful to be tolerated. We no longer regard duels(决斗) as an appropriate expression of anger resulting from one person's awareness of insulting behaviour on the part of another.

    Anger can be identified in the brain, where the electrical activity changes. Under most conditions EEG(脑电图) measures of electrical activity show balanced activity between the right and left prefrontal(额叶前部) areas. Behaviourally this corresponds to the general even­handed disposition(意向) that most of us possess most of the time. But when we are angry the EEG of the right and left prefrontal areas aren't balanced and, as a result of this, we're likely to react. And our behavioural response to anger is different from our response to other emotions, whether positive or negative.

    Most positive emotions are associated with approach behaviour: we move closer to people we like. Most negative emotions, in contrast, are associated with avoidance behaviour: we move away from people and things that we dislike or that make us anxious. But anger is an exception to this pattern. The angrier we are, the more likely we are to move towards the object of our anger. This corresponds to what psychologists refer to as offensiveanger: the angry person moves closer in order to influence and control the person or situation causing his anger. This approach­and­confront behaviour is accompanied by a leftward prefrontal asymmetry(不对称) of EEG activity. Interestingly, this asymmetry lessens if the angry person can experience empathy(同感) towards the individual who is bringing forth the angry response. In defensiveanger, in contrast, the EEG asymmetry is directed to the right and the angry person feels helpless in the face of the anger­inspiring situation.

    Here is an astonishing and signficant fact:Mental work alone can't make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲劳). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.

    So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.

    Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England's most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”

What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated—those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.

Easy Habits That Help You Live Longer

    Go for a jog

    Among all the things you can do to achieve longevity, one of the most critical is to exercise. Aerobic activity, like running, is important for getting your blood pumping and your heart working. A recent study showed that a one-hour run adds seven hours to your life, up to four hours per week. People who run have a 25 to 40 percent reduced risk of early death, and live about three years longer.

    Get more sun—but not too much

    The “Sunshine vitamin” -vitamin D, that is-has been shown to fight disease, improve bone health, and avoid depression. One study even found it to extend lifespan by 33 percent. But because vitamin D comes from the sun, and our modem lives don't let us spend much time outside, we might not be getting enough. Getting 15 to 30 minutes of sun exposure a day should be enough for vitamin D production.

    Eat more plant protein

    A recent study from Harvard found that people who ate a diet high in processed meats like ham, were at a higher risk of death—but those who got their protein from plants had a lower risk, especially of heart disease-related deaths. The study said that for every three percent increase in calories from plant protein there was a reduction in risk of death by 10 percent.

    Eat nuts

    Although you may think nuts are unhealthy because they are calorically high, the exact opposite is true—they can actually extend your life. A study from Harvard found that daily nut-eaters were 20 percent less likely to die during the study. Specifically, the rates of death from heart and breathing disease were reduced. Other research has shown walnuts have a huge role in heart health because of the amount of antioxidants (抗氧剂）they contain.

    Modern life is impossible without travelling. The fastest way of travelling is by plane. With a modern airline you can travel in one day to places which it took a month or more to get to hundred years ago.

    Travelling by train is slower than by plane, but it has its advantages. You can see the country you are travelling through. Modern trains have comfortable seats and dining-cars. They make even the longest journey enjoyable.

    Some people prefer to travel by sea when possible. There are large liners and river boats. You can visit many other countries and different parts of your country on them. Ships are not so fast as trains or planes, but travelling by sea is a very pleasant way to spend a holiday.

    Many people like to travel by car. You can make your own timetable. You can travel three or four hundred miles or only fifty or one hundred miles a day, just as you like. You can stop wherever you wish where there is something interesting to see, at good restaurant where you can enjoy a good meal, or at a hotel to spend the night. That is why travelling by car is popular for pleasure trips, while people usually take a train or plane when they are travelling on business.
