Scientists know that there are two basic approaches to prolonging life. One approach is the elemination of the diseases that generally affect older people -diseases such as cancer, heart attcaks, strokes and high tension or cholestrol. The other is the delay of the process of growing old -the deterioration(bozulma) of the body.

In recent years scientific researchers have spent a lot of time in the study of the process for 10 to 15 years. The result will be that more people will live longer, more healthful lives. At present, scientists believe that the right diet, exercise, medical advice and mental attitude(tavir) many people can live to be 100 years old.

Gerontologists, people who specialize in studies of the problems of growing pld, are investigating why body cells slow down and eventually die. They feel that delaying this slowing down process would help postpone(ertelemek) death. In a number of American Universities, scientists are studying the activity of cells, the immunities of cells; and the effects of diet and internal body temperature on aging. If their studies are successful, the results should help to improve the quality of life for older people in the next few years, as well as increase in the life span of the next generation.

What will some of the effects of longer life be? For one thing, by adding extra, more healthful years to a person's life , youth and middle-age will be prolonged(uzatmak). A person's productivity and efficiency will be increased. In addition, it is possible that such persons will contribute(katkida bulunmak) more to the benefit of society and will, in turn, enjoy more of the benefits society society has to offer

Longer lives for more people would affect the life styles of a society. People who retire in middle-age might want education and training to begin new careers; thus, colleges and universities would have to offer classes designed to help such people. Communities especially planned and built for older people would greatly increase in number and might even serve as "second-career" communities in which older persons could work in their second or even third career after retirement.

One major problem that longer lives for more people would bring is that of money. Pensions(emekli maasi) would have to last longer which means that governments would have to plan to provide adequate funds to meet the increased cost of pensions. Otherwise, tragedy could be the result if people lived longer but did have any financial stability.
