If you want to stay young, sit down and have agood think. This is the research finding of a team of Japanese doctors who say that most of our brains are not getting enough exercise and as a result, we are aging unnecessarily soon.

    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the

process of aging could be slowed down.With a team of colleagues at Tokyo National University,

he set about measuring brain volumes of a thousand people of different ages and jobs.

Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.

    The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.

    Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."w

The team of doctors wanted to find out ______.

A. why certain people age sooner than others   B. how to make people live much longer

C. the size of certain people's brains          D. the people with more intelligence

On what are their research findings based?

A. A survey of farmers in northern Japan.

B. Tests performed on a thousand old people.

C. The study of brain volumes of different people.

D. The latest development of computer technology.

Matsuzawa thinks that _______.

A. our brains grow as we grow older

B. the front section of the brain does not shrink

C. sixty-year-old people have better brains than thirty-year-olds

D. the contraction of brains is connected with brain exercise

According to the passage, which people seem to age slower than others?

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of out brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎缩) with age.
Contraction of front and side parts, as cells(细胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The findings show that contraction of the brain begins sooner in people in the country than those in the towns.

If you want to stay young，sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise, and as a result，we are ageing unnecessarily soon.

Professor Taijiu Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could be slowed down.

With a team of partners at Tokyo National University，he set about studying the brain volumes（体积） of a thousand people of different ages and various jobs.

Computer technology enabled the researchers to get exact measurement of the volume （容量）of the front and side sections of the brain，which relate to intellect（智能）and feelings，and determine the human character. The back section of the brain，which controls functions like eating or breathing，does not connect with age. One can continue living without intellectual or feeling abilities.

Contraction（收缩）of front and side parts - as cells die off - was observed in some subjects in their thirties, but it was still not obvious in some sixty and seventy year olds.

Matsuzawa concluded from his tests that there is a simple cure for the contraction normally connected with age using the brain.

The findings show in general conditions that contraction of the brain begins soon among people in the country than in the town. Those are at least at risk，says Matsuzawa，who are lawyers，followed by university professors and doctors. White collar workers doing regular work in government offices are, however，as likely to have shrink （收缩） as the farm workers，bus drivers and shop assistants.

Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must flow through a circle properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood movement is through using the brain，"he says. " Think hard and engage in conversation. Don’t depend on pocket calculators. "

　　Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)
