　　It is said that 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 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 volume of the front and side parts of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual on economical faculties. 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. Matsuzawa concluded from his tests that there is a simple way to the contraction normally connected with age—using the head.
　　The findings show in general terms that contraction of the brain begins sooner in people in the country than in the town. 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 (萎缩) brains as the farm wors drivers and shop assistants.
　　Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain. ” he says. “Think hard and engage in conversation. Don’t rely on pocket calculators. ”

　　Some of us feel well-rested after a solid eight hours of sleep. For others, closer to nine feels best. For others still, a little less will do. How much sleep we prefer to get is highly subjective. But how much sleep we need is a bit more concrete.
　　“Sleep time was one of the most visited pages on the NSF website, but it wasn’t really clear how those recommendations had been arrived at. ” Max Hirshkowitz, a sleep expert said.
　　To reassure that the information provided there was the most accurate and up to date, a group of 18 experts conducted a formal literature review. They focused on the body of research surrounding sleep duration in healthy human subjects that had been published in peer-reviewed journals between 2004 and 2014. Then they were able to fine-tune existing sleep duration recommendations as detailed below:
　　Newborns (0-3 months): 14-17 hours (range narrowed from 12-18)
　　Infants (4-11 months): 12-15 hours (range widened from 14-15)
　　Toddlers (1-2 years): 11-14 hours (range widened from 12-14)
　　Preschoolers (3-5): 10-13 hours (range widened from 11-13)
　　School-age Children (6-13): 9-11 hours (range widened from 10-11)
　　Teenagers (14-17): 8-10 hours (range widened from 8. 5-9. 5)
　　Young Adults (18-25): 7-9 hours (new age category)
　　Adults (26-64): 7-9 hours (no change)
　　“It’s the first time that any professional organization has developed age-specific recommended sleep durations” Hirshkowitz said, “It’s not an exact science, but it’s a start. Like most things, it’s successive approximation that gets you to the goal. The first time somebody built a wristwatch, it wasn’t very good, but after hundreds of years of making precise changes, to have a timepiece that doesn’t tell time is pretty unusual. ” As more and more research is conducted around sleep duration, subsequent minor changes will be made, he said, helping experts to zero in on the absolute best recommendations to give to patients.
　　【文章大意】本文中作者介绍了一些专家通过对发表在2004年到2014年期间杂志上对人们需要多长时间的睡眠给出的科学依据。
