  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 said that most of our brains are not getting enough   1  , and as a result, we are   2   old unnecessarily soon.

  Professor Matsuzawa wanted to find out why quite   3   farmers in northern Japan appeared to be losing their ability to   4   and reason(推理)at a rather early age, and how the speed of getting old could be   5   down.

  With a team of researchers at Tokyo National University, he set about   6   brain volumes(容量)of a thousand people of different ages with different jobs.

  Computer technology helped the researchers to get most   7   measures of the volume of the front and side parts of the brain, which   8   something to do with intellect(智力)and feelings, and   9   the human character.As we all know, the back part of the brain, which   10   tasks like eating and breathing, does not contract(萎缩)with ages.

  Contraction of front and side parts was   11   in some people in their thirties,   12   it was still not found in some sixty or seventy-year-olds.

  Matsuzawa concluded from his tests that there is a simple way to   13   the contraction   14   the head.

  The findings show that contraction of the brain begins   15   in people in the   16   than in towns.Those with   17   possibility are lawyers,   18   by university professors and doctors.  19   workers doing the same work   20   in government offices are as possible to have contracting brains as the farm workers.
