In ______ doctors say that for lack of exercise of our ______, we are growing ol

A team of Japanese doctors say that most of our brains are not getting enough exercise and as a result, we are growing old unnecessarily soon.
     One of the professors, Tai Ju Matsuzsws, wanted to find out why some bodily healthy farmers soon lost their ability to think and reason and how the speed of getting old could be slowed down.
     With a team of researchers he set about measuring brain volumes of a thousand people of different ages with different jobs. Computers help them to get most exact measurement of the volume of the front and side parts of the brain which have something to do with intellects and feelings and decide the human character. The back part of the brain which controls tasks like eating and breathing, doesn’t contract with the age. Contraction of front and side parts-as cells die off, was seen in some people in their thirties, but it was still not found in some 60 and 70-year-olds.
     After the study, the professor concluded that there is a simple way to prevent contraction-using the head often and the contraction of the brain begin sooner in people in the country than in the town.
