Computer technology enabled the researchers to obtain precise measurements of the activity of the front and side sections of the brain, which relate to intelligence and feeling, and

determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not change with age, and one can continue living without the ability to think and feel.)

Change of front and side parts, as bits die off, was observed in some subjects in their thirties, but it was still not to be seen in some sixty-and-seventy-year-olds.

Matsuzawa discovered from his tests that there is a simple answer to the loss normally associated with age?using the head.

The findings show in general terms that the decrease of the brain's ability to think begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.

Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must move around properly in the head to supply the fresh oxygen the brain needs. "The best way to keep blood moving well is through using the brain." He says, "Think hard and engage in conversation. Don't rely on pocket calculators."

Ours is a big world, and full of many different people. People with many varying (不同的) points of view are often running up against others who have different opinions. Those of us who smoke are just one group of many. Recently, the activism (采取行动) of non-smokers has reminded us of the need to be considerate (体谅的) of others when we smoke in public. But, please! Enough is enough! We should like to remind non-smokers that being polite is a two-way street. If you politely request that someone not smoke you are more likely to receive an agreeable response than if you give an ugly look and say something unkind. If you speak directly to someone, you are more likely to get what you want than if you complain to the management.

Many of us have been smoking for so long that we sometimes forget that others are not used to the smell of burning tobacco. We' re human, and like everyone else, we occasionally offend unknowingly. But most of us are open to friendly suggestions and comments, and quite willing to change our behavior to accommodate others.

Smokers are people, too. We laugh and cry. We have hopes, dreams, and aspirations. We have children, mothers, and pets. We eat our hamburgers (汉堡包) with everything on them and give respect to the flag at Fourth of July picnics. We hope you'll remember that the next time a smoker light up in public.
