6、lderly 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 afflicting fewer and fewer people and when they do strike, it is much later in life.In the
7、last 14 years, the National long-term Health 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
8、 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 accelerate. Other diseases of old age dementia, stroke, arteriosclerosis and emphysema are also troubling fewer and fewer people.It really raises t
9、he 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 retrea

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 education
13、live an extra seven years.

Almost 80% of those in the 1994 surv
14、ey could complete everyday activities ranging from eating and dressing unaided to complex tasks such as cooking and managing their finances. That represents a significant drop in the number of disabled old people in the population. If the trends apparent in the United States 14 years ago had continu
15、ed, researchers calculate there would be an additional one million disabled elderly people in today population. According to Manton, slowing the trend has saved the United States governments Medicare system more than $200 billion, suggesting that the greying of Americas population may prove less of
16、a financial burden than expected.The increasing self-reliance of many elderly people is probably linked to a massive increase in the use of simple home medical aids. For instance, the use of raised toilet seats has more than doubled since the start of the study, and the use of bath seats has grown by more than 50%.
