Elderly people are growing healthier, happier and more independent, say American scientists. The results of a 14-year study to be announced later this month reveal that the diseases associated with old age are affecting fewer and fewer people and when they do suffer a stroke , it is much later in their life. In the last 14 years, the National Long-term Care Survey has gathered data on the health and lifestyles of more than 20,000 men and women over 65. Researchers, now analyzing the results of data gathered in 1994, say arthritis, high blood pressure and circulation problems -- the major medical complaints in this age group -- are troubling a smaller proportion every year. And the data confirms that the rate at which these diseases are declining continues to increase. Other diseases of old age -- dementia, strokes, arteriosclerosis and emphysema -- are also troubling fewer and fewer people. "It really raises the question of what should be considered normal ageing," says Kenneth Manton, a demographer from Duke University in North Carolina. He says the problems doctors accepted as normal in a 65-year-old in 1982 are often not appearing until people are 70 or 75. Clearly, certain diseases are beating a retreat in the face of medical advances. But there may be other contributing factors. Improvements in childhood nutrition in the first quarter of the twentieth century, for example, gave today's elderly people a better start in life than their former generations. On the downside, an increase in some cancers and bronchitis may reflect changing smoking habits and poorer air quality, say the researchers. "These may be subtle influences," says Manton, "but our subjects have been exposed to worse and worse pollution for over 60 years. It's not surprising we see some effect." One interesting correlation Manton uncovered is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their... Which of the following is NOT considered as a contributor to elderly people getting healthier? A) Medical improvement. B) Good childhood nutrition. C) Change of air quality. D) Better education.

Any of a large number of simple factors may take it difficult for someone to fall asleep or remain asleep.His matters may be too soft or too hard.If there are too many blankets on a hot night, he may be too warm; if the bedclothes are too light he may feel cold during the night.If it is not dark enough, or too noisy, this may cause difficulty in sleeping.Eating shortly before going to bed also be responsible for insomnia.Stimulating drinks, such as tea or coffee, can also keep people awake.

Q: It might sound ridiculous that goal setting could actually hold you back from completing tasks and dreams you may have. But it seems like everyone tells you should be setting goals for everything you want to accomplish, short term and long term. Goals can help you sometimes, but in some cases they just lead to constant frustration and they actually bring you down. Let's look at this a little closer with an example. A lot of people might set forth as a goal. Many people jump online and are looking to start a business online as a way to make money from home and let's say they set a goal to make $10,000 in their first month. They do this because they seem tons of people making large sums of money in very little time so they think, $10,000 a month, that shouldn't be too hard. But what happens when you only bring in $1,000 in your first 30 days online? If this is pure profit you might still be happy but this is nowhere near reaching the goal you originally set out to meet. So naturally you would feel like you failed to reach your goal and you may be a little disappointed in yourself. If you continue not to reach this goal month in month , it starts to add up and really weighs on you. I'm not saying that they are bad and you shouldn't set them but you need to realize that you should not be emotionally attached to your goals. An alternative approach would be to set certain milestones for when you want to accomplish things and start out small. Build your confidence by accomplishing smaller feats and if you overproduce, then it will be a nice surprise. You have to have some sort of end result in mind but break it down in to a day by day task. It makes it a lot easier for you to handle by just knowing everyday you have to complete a few small tasks and over time the snowball will roll into great things. In Paragraph 2 , the writer used the example to _ . A) persuade readers not to be greedy for money B) prove that goals often result in frustration. C) show goal setting sometimes stops you realizing your dreams D) advise readers not to set goals to avoid frustration
