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.

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.
