Question

    If you want to stay young, sit down and have a good ________ . 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 growing old unnecessarily soon.

Professor Taiju Matsuzawa wanted to ________ 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 ________ .

________ a team of researchers at Tokyo National University, he set about measuring(测量)brain size of a thousand ________ of different ages with different jobs. Computer technology helped the researchers to get most ________ measurements of the size of the front and side parts of the brain, which have ________ to do with intellect and feelings, 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, which means becoming smaller, with age.

Contraction of front and side parts-as cells die oil-was seen in some people in their thirties, ______ it was still not found in some sixty and seventy-year-olds.

Matsuzawa concluded from his tests that there is a simple way to ________ the contraction-using the head. "Those with ________ possibility," says Matsuzawa, "are lawyers, followed by university professors and doctors. White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm worker, bus driver and shop assistant."
