The problem of old age is known as one of the most serious problem in today's world. The old people can be seen everywhere. As is shown in the graph, the number of people in the world over the age of sixty will have increased to 600 million by the end of this century. And by the time, there will also be twice as many people over the age of eighty. In the ten years between 1970 and 1980, there was a 23.7% increase in the number of people aged over sixty-five in the industrial world, and an even bigger increase of 38.2% in the developing world.
With the development of economy, the rise in people's living standards and the improvement of medical conditions, people are living longer and longer. Furthermore, birth rates are falling as the pace of population growth slows down. As a result, the number of old people in the world is experiencing an increase. Though the increase will cause manifold social and economic consequences, we can take effective measures to deal with it. So I believe a bright tomorrow for old people will be achieved through efforts of every person.

老年问题被认为是当今世界最严重的问题之一。到处都可以看到老年人。如图所示，到本世纪末，六十岁以上的世界人口将增至6亿人。到那时，也会有两倍于八十岁以上的人。在1970至1980年间的十年间，工业世界六十五岁以上人口增加了23.7%，发展中世界人口增长了38.2%。
随着经济的发展，人民生活水平的提高，医疗条件的改善，人们的寿命越来越长。此外，随着人口增长速度放慢，出生率也在下降。结果，世界上老年人的数量正在增加。虽然增加会造成多种社会和经济后果，但我们可以采取有效措施加以处理。所以我相信，老年人的光明明天将通过每个人的努力来实现。
