[简答题]

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 at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
Computer technology enabled the researchers to obtain precise measurements of the volumes of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intel

If you want to stay young, sit down and have a good think. This is the research result of Professor Faulkner, who says that most of our brains are not getting enough exercise and as a result, we are ageing unnecessarily soon.
Professor Faulkner wanted to find out why healthy farmers in northern Japan appeared to be losing their ability to think and to reason at a relatively early age, and how the process of ageing could be slowed down.
He set about measuring brain volumes of a thousand people of different ages and occupations.
Computer technology enabled him to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intelligence and emotion, and determine the human character.
Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties, but it was still not evident in some sixty and seventy-year-olds.
Faulkner concluded from his tests t
A. our brains shrink as we grow old
B. the front section of the brain does not shrink
C. seventy-year-olds have better brains than sixty-year-olds
D. thinking can slow down the process of ageing
