Researchers investigating brain size and mental ability say their work offers evidence that education protects the mind from the brain’s physical deterioration. It is known that the brain shrinks as the body ages, but the effects on mental ability are different from person to person. Interestingly, in a study of elderly men and women, those who had more education actually had more brain shrinkage. "That may seem like bad news," said study author Dr. Edward Coffey, a professor of psychiatry and of neurology at Henry Ford Health System in Detroit. However, he explained, the finding suggests that education allows people to withstand more brain-tissue loss before their mental functioning begins to break down. The study, published in the July issue of Neurology, is the first to provide biological evidence to support a concept called the "reserve" hypothesis, according to the researchers. In recent years, investigators have developed the idea that people who are more educated have greater cognitive reserves to draw upon as the brain tissue to spare. Examining brain scans of 320 healthy men and women ages 66 to 90, researchers found that for each year of education the subjects had, there was greater shrinkage of the outer layer of the brain known as the cortex. Yet on tests of cognition and memory, all participants scored in the range indicating normal. "Everyone has some degree of brain shrinkage," Coffey said. "People lose (on average) 2.5 percent per decade starting at adulthood." There is, however, a "remarkable range" of shrinkage among people who show no signs no mental decline, Coffey noted. Overall health, he said, accounts for some differences in brain size. Alcohol or drug use, as well as medical conditions such as diabetes and high blood pressure, contribute to brain-tissue loss throughout adulthood. In the absence of such medical conditions, Coffey said, education level helps explain the range of brain shrinkage exhibited among the mentally-fit elderly. The more-educated can withstand greater loss. Coffey and colleagues gauged shrinkage of the cortex by measuring the cerebrospinal fluid surrounding the brain. The greater the amount of fluid, the greater the cortical shrinkage. Controlling for the health factors that contribute to brain injury, the researchers found that education was related to the severity of brain shrinkage. For each year of education from first grade on, subjects had an average of 1.77 milliliters more cerebrospinal fluid around the brain. For example, Coffey’s team reported, among subjects of the same sex and similar age and skull size, those with 16 years of education had 8 percent to 10 percent more cerebrospinal fluid compared with those who had four years of schooling. Of course, achieving a particular education level is not the definitive measure of someone’s mental capacity. And, said Coffey, education can be "a proxy. for many things". More-educated people, he noted, are often less likely to have habits, such as smoking, that harm overall health. But Coffey said that his team’s findings suggest that like the body, the brain benefits from exercise. "The question is whether by continuing to exercise the brain we can forestall the effects of (brain shrinkage)," he said. "My hunch is that we can." According to Coffey, people should strive throughout life to keep their brains alert by exposing themselves to new experiences. Travelling is one way to stimulate the brain, he said; a less adventuresome way is to do crossword puzzles. "A hot topic down the road," Coffey said, will be whether education even late in life has a protective effect against mental decline. Just how education might affect brain cells is unknown. In their report, the researchers speculated that in people with more education, certain brain structures deeper than the cortex may stay intact to compensate for cortical shrinkage. According to Coffey’s research, the brain may benefit from ______.
Story telling is an ancient and honored art. Story tellers entertained during the long dark hours before sleep arrived after the sun disappeared over the western horizon. But the story teller’s job is more than just entertainment Before the printed page appeared, story tellers provided cultural continuity, preserving the past to serve as guide through the future. Storytellers told tales of heroes to provide positive examples, the legends that held the tribe together and provided its identity, and the stories of foolish or evil beings to remind young and old the penalties for not riving correctly. Even behavior too horrible to speak of directly, such as cannibalism, cowardice or death, could be examined through the mediation of a story. Even today, books, magazines, radio, television and movies still have not replaced the storyteller. None of these permanent, reproducible media are able to deliver a personal, individualized message with the impact of a well-told story. Whether the purpose of a story is to set a mood, to entertain, to teach a lesson, to amuse or to scare, nothing works like a good story at the right moment. A story with an obvious message concerning the results of another person’s misbehavior can deliver a warning and deterrent that a direct confrontation can not produce and the story will do so without hurting egos. A positive relationship can be maintained and, sometimes, even strengthened while still delivering an unwelcome message. This is the power of the storyteller. Not every story will fit every situation. The story teller needs to select a story which will meet the needs of the situation and thon the story teller must tailor the story to fit the time available, the age of the audience, the location and the mood desired. A good story choice will capture the interest of the audience. Audience members will relate to a location, experience or emotion that they share in common with the story teller and will suspend disbelief long enough to be drawn into the story as it unfolds. Good stories build to a climax with a beginning, a middle and an end. The elements of the story revealed in each section will lead to the next. Predicaments and solutions will depend on the details of the story revealed in an earlier section. However, better stories may add a twist to make the ending unexpected and, therefore, more interesting. Scary stories should be matched to the age of the audience. A little feeling of fright as the story is told may be beneficial in learning how to deal with scary things, but the use of lingering fear that is carried away from the stow is simply terrorizing a susceptible person and helps no one. It is the responsibility of the story miler to determine what is appropriate and not to abuse the audience’s good faith. Stories can come from nearly anywhere. Folk tales, myths, legends, history (especially local history), Indian stories, adventure yams and other stow tellers are all sources of inspiration. A short listing of collected stories is appended along with several examples of good stories. However, the best sources of stories for good stow tellers are their own experiences. When inspiration and opportunity unite, a story is ready to be born. No matter what the source, the best stories are those of which the story teller has some personal experience or knowledge. This can be combined with other sources and a little practice to produce the tale to be told. When personal experience is the base on which a story is built, the stow will "ring true" to the audience and have a greater vitality. A dislike of insects crawling on your skin, an encounter with a wild animal or the memory of a weird noise experienced when you were home alone can each provide the experience or feeling that will form the basis of a story. The experience need only be a wee part of the story, but that can be enough. When you have chosen a source from a book or another story teller, learn the stow thoroughly before giving it publicly. Do not memorize the story! Memorize the outline and flow of the stow. Take special note of key points, events and names that the story hinges on. Also note where and how they fit in the narrative. If there are key phrases make sure you anchor them in your memory so they come out naturally where they should. Don’t try to deliver a stow verbatim, a story should be told in your own words. Make the story a part of you and then share that part with you. Live the stow as you tell it. To deliver a story, you should do all of the following EXCEPT ______. A. capturing the audience’s attention right at the beginning. B. making as few gestures as possible. C. appealing to the audience’s sense of sight. D. monitoring feedback from the audience.
The single most shattering statistic about life in America in the late 1990s was that tobacco killed more people than the combined total of those who died from AIDS, car accidents, alcohol, murder, suicide, illegal drugs and fire. The deaths of more than 400, 000 Americans each year, 160, 000 of them from lung cancer, make a strong case for the prohibition of tobacco, and particularly of cigarettes. The case, backed by solid evidence, has been made in every public arena since the early 1950s, when the first convincing link between smoking and cancer was established in clinical and epidemiological studies—yet 50 million Americans still go on smoking. tobacco-related illness. It is a remarkable story, clearly told, astonishingly well documented and with a transparent moral motif. Most smokers in America eventually manage to quit, and local laws banning smoking in public have become common, but the industry prospers. The tobacco companies have survived virtually everything their opponents have thrown at them. At the end of his story, Mr. Brandt writes: "The legal assault on Big Tobacco had been all but repelled. The industry was decidedly intact, ready to do business profitably at home and abroad. "Although the conclusion is not to his liking, Mr. Brandt’s is the first full and convincing explanation of how they pulled it off. Cigarettes overcame any lingering opposition to the pleasure they gave when American soldiers came to crave them during the World War I. War, says Mr. Brandt, was "a critical watershed in establishing the cigarette as a dominant product in modern consumer culture. " Cigarettes were sexy, and the companies poured money into advertising. By 1950 Americans smoked 350 billion cigarettes a year and the industry accounted for 3.5% of consumer spending on non-durables. The first 50 years of the"cigarette century"were a golden era for Big Tobacco. That was simply because, until the 1940s, not enough men had been smoking for long enough to develop fatal cancers (women did not reach this threshold until the 1970s). The first clinical and epidemiological studies linking eigarette-smoking and lung cancer were published only in 1950. By 1953 the six leading companies had agreed that a collective response was required. They paid handsomely for a public-relations campaign that insistently denied any proof of a causal connection between smoking and cancer. This worked well until 1964, when a devastating report from the surgeon-general’s advisory committee in effect ended medical uncertainty about the harmfulness of smoking. But Big Tobacco rode the punches. When the Federal Trade Commission (FTC) ruled that health warnings must appear on each pack, the industry, consented. But it shrewdly exploited the warning: "In a culture that emphasised individual responsibility, smokers would bear the blame for willful risk-taking," notes Mr. Brandt. Many cases for damages against the companies foundered on that rock. Cigarette-makers also marshaled their numerous allies in Congress to help the passage of a law that bypassed federal agencies such as the FTC, and made Congress itself solely responsible for tobacco regulation. Describing the pervasive influence of tobacco lobbyists, he says: "Legislation from Congress testified to the masterful preparation and strategic command of the tobacco industry. " However, the industry was powerless to prevent a flood of damaging internal documents, leaked by insiders. The companies were shown, for instance, to have cynically disregarded evidence from their in-house researchers about the addictive properties of nicotine. Internal papers also showed that extra nicotine was added to cigarettes to guarantee smokers sufficient" satisfaction". Despite such public-relations disasters, the industry continued to win judgments, most significantly when the Supreme Court rejected by five votes to four a potentially calamitous attack that would have given the Federal Drug Administration the power to regulate tobacco products. The industry’s shrewdest move was to defuse a barrage of eases brought by individual states, aiming to reclaim the cost of treating sick smokers. The states in 1998 accepted a settlement of $246 billion over 25 years (the price of a pack rose by 45 cents shortly afterwards). In return, the states agreed to end all claims against the companies. But the settlement tied the state governments to tobacco’s purse-strings; they now had an interest in the industry’s success. For those who thought the settlement was akin to" dancing with the devil", it appeared in retrospect that the devil had indeed had the best tunes, reports Mr. Brandt. To his credit, he manages to keep his historian’s hat squarely on his head. But you can feel the anguish. According to the author, Allan Brandt’s attitude towards the cigarette reflected in his book is one of
During the reign of Augustus the Rome army became a professional one. Its core of legionaires was composed of Roman citizens who served for a minimum of twenty five years. Augustus in his reign tried to eliminate the loyalty of the legions to the generals who commanded them, forcing them to take an oath of allegiance directly to him. While the legions remained relatively loyal to Augustus during his reign, under others, especially the more corrupt emperors or those who unwisely treated the military poorly, the legions often took power into their own hands. Legions continued to move farther and farther to the outskirts of society, especially in the later periods of the empire as the majority of legionaires no longer came from Italy, and were instead born in the provinces. The loyalty the legions felt to their emperor only degraded more with time, and lead in the 2nd Centry and 3rd Century to a large number of military usurpers and civil wars. By the time of the military officer emperors that characterized the period following the Crisis of the Third Century the Roman army was just as likely to be attacking itself as an outside invader. Both the pre- and post-Marian armies were greatly assisted by auxiliary troops. A typical Roman legion was accompanied by a matching auxiliary legion. In the pre-Marian army these auxiliary troops were Italians, and often Latins, from cities near Rome. The post-Marian army incorporated these Italian soldiers into its standard legions (as all Italians were Roman citizens after the Social War). Its auxiliary troops were made up of foreigners from provinces distant to Rome, who gained Roman citizenship after completing their twenty five years of service. This system of foreign auxiliaries allowed the post-Marian army to strengthen traditional weak points of the Roman system, such as light missile troops and cavalry, with foreign specialists, especially as the richer classes took less and less part of military affairs and the Roman army lost much of its domestic calvary. At the beginning of the Imperial period, the foreign auxiliaries ______. A. made up 60 legions B. equalled the legionaires in number, C. didn’t make up a big portion of Rome army D. declined in Rome army
