23. 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 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 volumes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the volume of the front and side part of the brain, which have something to do with intellect and feelings, and decide the human character. As we all know, the back part of the brain, which controls tasks like eating and breathing, does not contract with 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 sixty and seventy-year-old.
Matsuzawa concluded from his test 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 in the towns. Those with least 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 contraction brains as the farm workers, bus drivers and shop assistants.
