Today people are living to be much older thanever before. Some of the main reasons for this arethe improved health care and better nutritionavailable to everyone.
Medical care is more available to people. Although not everyone can get the best heathcare, everyone can get basic heath care and advice. When people are seriously ill, they can goto 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 theyneeded. They made do with herbal medicines or folk remedies. Of course, some of theseworked, but not for the more serious diseases.
The quality of medical care has improved. That’s also a factor in longevity. Doctors knowmore now about what causes disease and how to care it ,Years ago, doctors only knew aboutthe most basic diseases and cures. Medicine was not very advanced. You could die fromsomething as simple as an infection from a cut. Now we have antibiotics and other medicinesto help cure infections.

Improved medical care and healthy eating habits has greatly expanded our life spans. What weneed to do now is make sure that everyone in the world has these benefits.
