4、 small correlation between wealth and happiness-accounting for about one percent of the happiness reported by people answering the surveys. And for some groups, that relationship may be considerably bigger. People who are poor seem to get much happier when their monetary prospects improve; so do the

5、 very sick. In these cases, Ubel speculates, people may be protected from negative circumstances by the extra cash. Another possibility is that the money brings an increase in status, which may have a greater impact on happiness. Why doesn't wealth bring a constant sense of joy? "Part of th

6、e reason is that people aren't very good at figuring out what to do with the money," says George Loewenstein, an economist atCarnegie Melton University. People generally overestimate the amount of long-term pleasure they'll get from a given object.Sometimes, Loewenstein notes, the way p

7、eople spend their money can actually make them less happy. For example, people derive a great deal of pleasure from interacting with others. If the first thing lottery winners do is to quit their job and to move to a palatial(富丽堂皇的)but isolated estate where they don't see any neighbours, they co

12、s from one body and integrate them into another, granting the lucky recipient a longer, better life. Sadly, every year thousands of other people are less fortunate, dying while they wait for suitable organs to be found. The terrible constraint on organ transplantation is that every life extended dep

13、ends on the death of someone young enough and healthy enough to have organs worth transplanting. Such donors are few. The waiting lists are long, and getting longer. Freedom from this constraint is the dream of every transplant surgeon. So far attempts to make artificial organs have been disappointi

14、ng: Nature is hard to mimic. Hence the renewed interest in trying to use organs from animals. Doctors in India have just announced that they have successfully transplanted a heart from a pig into a person. Pressure to increase the number of such "xenotransplants"(异种移植)seem to be growing. I

15、n Europe and America, herds of pigs are being specially bred and genetically engineered for organ donation. During 1996 at least two big reports on the subject-one in Europe and one in America- were published. They agreed that xenotransplantation was permissible on ethical grounds, and cautiously re

16、commended they be allowed. The ethics of xenotransplantation are relatively unworrying. People already kill pigs both for food and for sport; killing them to save a human life seems, if anything, easier to justify. However, the science of xenotransplantation is much. less straightforward. Import an

17、organ from one animal to another and you may bring with it any number of infectious diseases. That much is well known. However, coping with this danger is not merely a matter of screening for obvious ills such as parasites. Many diseases that could harm humans may be both undetectable and harmless i

18、n their natural hosts. Diseases that have been dormant for years may suddenly become active if they find themselves in a new environment, such as a human recipient's body. After that, they may start to infect other people. 1. Despite transplant surgeons' work, every year many people die beca
