During the 19th century, scientists found that when certain parts of the brain of a person were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modern research has discovered that this is not so, for it is not easy to show exactly what each part of the brain does.
In the past fifty years there has been a great increase in the amount or research done on the brain. Scientists have found out that the way the brain works is not so simple as people in general may think. Chemists tell us that about 100,000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happened to us. We may not be able to think of the things we have heard and seen but it is kept there in the store-house of the human mind. Earlier scientists thought that the power of one’s brain got weaker and weaker as one grows older. But it is plenty of exercise, it keeps its power. It is now thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has proved that an old person who has always been active in the mind has a quicker mind than a young person who has done physical work without using much of his brain.

What causes your computer a slow one? The problem lies with changes that occur to the PC's software. The 2 most   51   causes of slowdown (along with easy solutions) are:

Registry errors  -  the most common problem

  Every    52    you load a program, game or file, your PC's software registry is updated with new instructions needed to operate that item.   53   , when the item is removed, these instructions usually remain on your PC.  Every time you run your computer it   54   to carry out these instructions but, because the related program can't be found, it causes a registry error.  Your PC is doing a lot   55   work than it should be and the result is a significantly   56   computer.

Like poorly managed stress, anger that isn’t handled in a healthy way can be not only uncomfortable, but even damaging to one’s health and personal life. Consider the following research on anger:

One study from the University of Washington School of Nursing studied   1   problems in husbands and wives. Researchers cited(引用) previous evidence that anger problems and depressive symptoms have been linked to all major   2   of death, but found that wives specifically found a greater association between anger and   3   of depression,   4   men tended to instead experience an   5   between anger and health problems.

According to a study from Ohio State University, those who had less control over their anger   6   to heal more slowly from wounds. Researchers gave blisters(起疱膏) to 98 participants and found that, after 8 days, those who had less control over their anger also tended to be   7   healers.    8   , those participants also tended to have more cortisol (a stress hormone) in their system during the blistering procedure,   9   that they may be more stressed by difficult situations as well.

  10   study from Harvard School of Public Health studied hostility(敌对行为) in men and found that those with   11   rates of hostility not only had poorer pulmonary functioning (breathing problems), but experienced higher rates of decline as they aged.

Research with children and   12   shows that anger   13   is important for the younger set as well. Findings showed that youth who cope inappropriately with their anger are at greater   14   for problem-ridden(受…支配的) interpersonal relationships. Their   15   is also at risk; those who cope poorly with anger tend to have more negative   16   when it comes to both mental and general health. This highlights the fact that anger management is an important skill to   17   early.

These are just a few of the many studies linking anger to   18   and emotional health problems, from the obvious to the   19   . Because poorly managed anger presents such a significant problem in so many areas of life, it’s important to take steps toward learning and using healthy anger management techniques in daily life,    20   stress management techniques.
