In Britain, within the lifetime of all the old people alive today, our life expectancy has rapidly shot up from an average of forty years to an average of seventy years. Although, in the last century, it was accepted that the body had been programmed to last for seventy years, until the 1960s it was all too obvious that very few bodies ever did, and for a man to en-joy good health in old age was exceptional. Many of today's old people had such rough starts, such small scraps of education, such low wages and so few possessions generally, that they feel they are ending their days in luxury, although they may not be doing so in other people's eyes. 'Manage' is word they often use, and having 'managed' then, they manage now more easily. They will describe their poor and exhausting working lives for you without any feeling of hatred. Some are proud if they never cheated; and some are proud if they did and got away with it. However, many find that now is the deprived time. They are aware of gradual losses and of everything being taken away from them or placed out of reach by degrees. They are no longer considered as individuals. Constantly, as one talks to old people, one feels this struggle to claim their dignity and importance at the present time and not just to recall what they have been in the past. Perhaps, as the young begin to realize that they are likely to 'old' for twenty or more years, they will bring about the radical changes needed if the aged are to have the supportive conditions in their old age that they would really like. At present, both our treatment of 'the old' and the way we talk about them sometimes echo the actions and attitudes of our nineteenth-century ancestors, when they were considering' the poor'. 'The problems of the old are not our problems' is what we are often saying——politely and humanly, of course.Many old people in Britain today feel they are spending their remaining years in luxury because _______.A．they had a very hard life in the pastB．they had to manage to get away with cheating in their early yearsC．they remain as healthy as everD．they take pride in the fact that they never cheated
