    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 heath care, everyone can get basic heath 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 care 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
vegetable and fruits ,which are now available year-round.
    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.
