It is reported that people are living longer than acient time. What are causes of this phenomenon?I think there are three reasons to this phenomenon. Neat living enverinment, approprate diet and skilled medical treatment are essential departments which propel the longevity of human being.

Firstly of all, cleaning living enverinment is a fundemanted solution. It inludes cleaning and comfortable living enverinment, healthful habits and hygienic behavious. For example, the averiage life year of the Swiss has exceedes 70 years-old.The Swiss standard of cleanliness and hygiene is not only evident in the streets and houses, it is also found in the public toilets. It is represted in every aspects of soical life. It is easy to make a conclusion that cleaning surrding paly an important part in the longevity.

Next, balance diet play an important role in longevity. Try to balance the diet by eating more fruit and less fat. In India, there are so many vegeterians, meanwhile vegeterism is booming in western world. In developed world, balance diet always outweighs the one in developing countries. Japan is a milestone in all of developed countries.

lastly, medical treatment is important either. With the development of medicine, so many disease have not be untreated- hypertension, diabate, cadiovascular diseases and so on, even some cancers or sarcomas. In China, the average life expectancy is only 36.6 years before 1949. After half of century, it reach 71.8 years in 2002, close to that of a medium-level developed country, advandenced medical treatment contributes to progress of the longevity.

In sum, there are so many reasons contribute to the longevity of human being. As we believeing, with the dvelopment of science and technology, the longevity of human being would become longer than before.
