问答题

Prolonging human life has increased the size of human population. Many people alive today would have died of childhood diseases if they had been born 100 years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rate not an increase in birthrates, that has led to the population explosion.
Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering culture, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas, if the parents survived they could have another child.
In most contemporary societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-age people; unless they have wealth or private or government insurance, they must often “go on welfare” if they have a serious illness.
When older people become too weak and ill to care for themselves, they create grave problems for their families. In the past and in some traditional cultures they would be cared for at home until died. Today,with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and recovery hospitals have been built. These are often profit-making organizations, although some are sponsored by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply “dumping grounds” for the dying in which “care” is given by poorly paid, overworked, and unskilled personnel.

Longevity also pushes back the age of retirement, and not only for financial reason. Yes, unless people are prepared to save a lot more, our calculations suggest that if you are now in your mid-40s, then you are likely to work until your early 70s; and if you are in your early 20s, there is a real chance you will need to work until your late 70s or possibly even into your 80. But even if people are able to economically support a retirement at 65, over thirty years of potential inactivity is harmful to cognitive and emotional vitality. Many people may simply not want to do it.

4. On account of economic reason, retirement have to be delayed with the increasing number of centenarians.( )
