SOCIAL DEVELOPMENT AMELIORATES PEOPLE'S LIFE
Obviously, people today live a longer life than ever before. It is quite common to encounter folks whose ages surpass seventy, or even eighty; while in ancient times, average life span of multitude was merely approximate fifty, or even younger. As we can imagine, people who will be born in coming century can no doubt have longer life than us today. Generally speaking, several factors have contributed to this phenomenon; however, there are a few direct and paramount causes.
As a threshold matter, ameliorated medical conditions result in a healthier and thus longer life span. For instance, in the 19th century, masses suffered from several lethal diseases, including influenza, pneumonia, and so forth. Doctors of that period had nothing to do with these fatal illnesses; and thus myriad people died from unhealed diseases. With the development of medical facilities and methods of curing, flu or pneumonia is no longer a serious illness that can cause a man or woman to death. As a result, a much healthier life can be predicted.
Second, developed agricultural techniques also contribute much to longer life of human beings. For example, multitudes who were born in ancient period had no advanced automated instruments. Food they took as primary intake was limited to a few common foodstuff: grain, wheat, etc; even fish were extremely luxurious and not easy to catch. While in contemporary, developed agriculture provides us with affluent subsistence, such as all kinds of man-made food.
Third, various insurances is another factor that benefits our age. People today who are going to work in society will be offered a plan of insurance, which will help them throughout when they catch health problems later. The insurance will ensure that people can only spend a small portion of money that has to be used to work out sticklers -- for example, unemployment, flood damage, fire damage, and of course diseases.
In summary, developed and advanced scientific techniques and improved social welfare are the pivotal causes that effects on our longer life span. Furthermore, the pace of development of human beings never halts or slows down; people will own a happier and prolonged life in next century.
