In general, people are living longer now. Discuss the causes of this phenomenon. Use specific reasons and details to develop your essay.

　　People are living to be much older these days for a number of reasons. The main reasons are greater access to health care, improved health care, and better nutrition.

　　Basic health care is available to more people now. when someone is seriously ill, he or she can go to a public hospital. There are also more clinics and doctors than there used to be. Years ago, health care wasn’t available to everyone. Some people didn’t live near a doctor or hospital and other couldn’t pay for the care they needed.

　　People also live longer because the quality of health care has improved. Doctors now know more about diseases and cures. Years ago, people died young because of simple things such as an infection or a virus. Now we have antibiotics and other medicines to help cure infections.

　　The quality of nutrition has improved also. We eat more healthfully than we used to. We know that eating low-fat food can prevent heart disease, and we know that eating fruits and vegetables can prevent cancer.

　　Improved health care and healthy eating habits allow us to live longer. Now we need to make sure that everyone in the world has these benefits.
