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 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 (同事) at Tokyo National University, he set about measuring brain activity of a thousand people of different ages and varying (不同的) jobs.
Computer technology enabled the researchers to obtain precise measurements of the activity of the front and side sections of the brain, which relate to intelligence and feeling, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not change with age, and one can continue living without the ability to think and feel.)
Change of front and side parts, as bits die off, was observed in some subjects in their thirties, but it was still not to be seen in some sixty-and-seventy-year-olds.
Matsuzawa discovered from his tests that there is a simple answer to the loss normally associated with age?using the head.
The findings show in general terms that the decrease of the brain's ability to think begins sooner in people in the country than in the 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 brains as the farm worker, bus driver and shop assistant.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must move around properly in the head to supply the fresh oxygen the brain needs. "The best way to keep blood moving well is through using the brain." He says, "Think hard and engage in conversation. Don't rely on pocket calculators."

Answer 1

如果你想保持年轻，坐下来，有一个好的想法。这是研究小组发现，日本的医生，谁说，我们大多数的大脑得不到足够的运动，因此，我们的老龄化不必要很快。

松泽教授Taiju想找出原因，否则健康的农民在日本北部似乎失去了思考能力和理由在一个相对较早的年龄，以及如何老龄化过程中可以减缓down.With一组同事在东京国立大学，他开始测量脑容量的有1,000人的不同年龄和不同的职业。

计算机技术使研究人员能够获得精确的测量量的前面和侧面部分的大脑，它涉及到智力（智能）和情感，并确定了人权的性质。 （车尾部分的大脑，它控制功能，如进食和呼吸，没有合同，年龄，和一个能继续生活在智力或情绪学院。 ）收缩战线和侧面部分，作为细胞死亡外有人在一些受试者在30 ，但仍然没有明显的一些60和70岁。

松泽结束他的试验，有一个简单的补救办法收缩通常与年龄使用head.The结果显示在一般条件，收缩脑越早开始在全国人民比城镇。那些最危险，说松泽，律师，其次是大学教授和医生。白领做日常工作的政府部门，然而，作为有可能萎缩大脑的农场工人，公共汽车司机和商店assistant.Matsuzawa的调查结果表明，思想可以防止大脑萎缩。血液必须分发给适当的头部提供新鲜氧气的脑细胞的需要。 “最好的方式，要保持良好的血液循环，是通过使用的大脑， ”他说， “仔细想想，并进行交谈。不依赖袖珍计算器。

Answer 2

如果你想保持年轻，坐下来好好想想。这是研究小组发现，日本的医生，谁说我们大脑的大部分都没有得到足够的锻炼和作为一个结果，我们不必要的衰老。

教授想找出为什么日本北部的健康农民失去了思考的能力，在相对年轻的年龄，以及如何减缓衰老过程。

一组同事在东京国立大学，他开始测量大脑活动的一千人的不同年龄和不同的工作。

计算机技术使研究人员能够获得精确的测量活动的正面和侧面部分的大脑，其中涉及到智力和情感，并决定人的性格。（后面部分的大脑，它控制的功能就像吃和呼吸，不改变与年龄，和一个可以继续生活，没有能力去思考和感受。）

变化的正面和侧面部分，如位死亡，观察在一些科目在三十多岁时，但它仍然是不被视为在某些sixty-and-seventy-year-olds。

松泽发现他的测试，有一个简单的答案的丢失通常与年龄？使用头。

调查结果表明，一般而言，减少了大脑的能力，认为早在乡下的人们比在城镇。那些最危险，松泽说，是律师，其次是大学教授和医生。白领工人在政府部门做日常工作，然而，有可能发生脑萎缩作为农场工人，公共汽车司机和商店职员。

松泽的发现表明，思考可以防止大脑萎缩。血液必须走动在头供应新鲜的氧气，大脑需要。”最好的方式保持血液的移动是通过使用大脑。”他说，“要与人交谈。不要依赖袖珍计算器。”
