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.
