With the development of human society， people are living longer now. Many factors interacting together to enable the longer life. There are three most important causes： the quality of food has been greatly improved; people could have medical services; more and more people realize that regular sports benefit their health.
The improving quality of our food is the most important factor of the longer life. We could have not only enough food as we want， but also the healthier food. When we preparing food， we no longer consider the cost， but pay more attention to the nutritions of the food. With the development of transportation systems， inland people now could also enjoy seafood and tropical fruit.
Furthermore， governments are paying more and more money on medical establishments. Citizens could have medical services more easily. Because of the convenient medical service more illnesses could be detected at an earlier stage. Also， many illnesses that had been considered fatal could be cured today. The better detection and curement enable people's longer life.
Last but not least important is that people care more for their own health. Every morning you could see people doing sports outside. More and more people have realized the saying “life is locomotion”. Regular sports build up a strong body. Naturally， people with stronger body could resist more deseases.
To sum up， the development of our society causes the longer life of people. People have better food and better medical services. And people spend more time on sports to biuld up stronger bodies. As we could predict， people are going to live even longer.
Nowadays， more and more communities for old people are founded everywhere all over the world. When you walk in a department store， you will find that more and more products for old people have been put on the shelves. The population of old people in the world is growing rapidly， and the reason is people are living longer now. There are several explanations for this phenomenon.
First， under the development of science and technology， it's obviously the standards of living have been improved a lot. People work less and relax more these days than ten years ago. More entertainment has also been provided， hence people have more chances to entertain and keep a good mood everyday， which is essential for being healthy and living longer.
Moreover， highly developed health system is another significant factor for people to live for a long time. As the governments put more fund for health expenditure， more people are saved from the torture of illness.
Further more， the improvement in medicine also plays an important role. There's an undeniable fact that after people discovered the mysteries of gene， more and more newly developed medicine cured a lot of illness that can't be cured before. Besides all these explanations we discussed above， there are also many other reasons. But the main causes of people's longer life is the development of science and technology， efficient health system and improvement in medicine.
With the development of modern medicine， people are living longer now. There are many factors why people can live a longer life. In my opinion， there are three most important reasons： the quality of food has been greatly improved; people benifit from improved medical services; and more and more people realize the importance of regular sports and excercises to their health.
The improving quality of our food is the most important factor for a longer life. With the convenience of modern transportation and food processing technology， we can find any food in the market; and as our standard of living and income increases， we can affort to buy any kind of food we want. we no longer worry about the cost， but pay more attention to the nutritious balance of the food. Better food and better nutrition give us a healthier body.
Furthermore， the development of medical technolgy and method ensure a longer life for people. Many fatal deceases which were considered incurable before can now be treated and cured. Governments are paying more and more money on medical care and training of doctors and nurses. People can access medical services easily： regular physical examinations ensure that deceases can be found ealier and therefore can be treated in a timely fasion.
Last but not least， people care more about their own health and realised the importance of excercises to their health. Every morning you could see people doing sports outside. More and more people have realized the saying “Life is locomotion”. Regular sports build up a strong body. Sports like hiking， jogging， and swimming can all benifit our health. Naturally， people with stronger body could resist more deseases， and therefore can live longer.
To sum up， the progress of our society is the reason why people live a longer life now. People eat food and have access to better medical services. And people spend more time on sports and excercices to build stronger bodies. As we could predict， people are going to live even longer in the future.
Today people are living to be much older than ever before. Some of the main reasons for this are the improved health care and better nutrition available to everyone.
Medical care is more available to people. Although not everyone can get the best health care， everyone can get basic health care and advice. When people are seriously ill， they can go to a public hospital and be taken care of. Years ago， health care wasn't available to everyone. Some people didn't live near a doctor or a hospital， and others couldn't pay for the care they needed. They made do with herbal medicines or folk remedies. Of course， some of these worked， but not for the more serious diseases.
The quality of medical care has improved. That's also a factor in longevity. Doctors know more now about what causes disease and how to cure it. Years ago， doctors only knew about the most basic diseases and cures. Medicine was not very advanced. You could die from something as simple as an infection from a cut. Now we have antibiotics and other medicines to help cure infections.
People are also living longer now because of better nutrition. We're eating better and more healthfully than we used to. That's reduced the number of people with heart disease and cancer. We try to eat low-fat foods and eat more vegetables and fruits， which are now available yearround. Improved medical care and healthy eating habits has greatly expanded our life spans. What we need to do now is make 'sure that everyone in the world has these benefits.
