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... Question: What is the main reason for better-educated people to live longer according to Manton? - They maintain a lower level of stress. - They have learnt more about medical care. - They have a higher income to support themselves. - They pay much more attention to their physical health.
They pay much more attention to their physical health.

Q: Read the following article and select the best answer. Article: 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. Question: According to the passage, always sticking to our goals is _ . - important - unnecessary - ridiculous - natural
A: unnecessary
