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 heath care,everyone can get basic heath care and advice. When people are seriously ill, they can go to apublic hospital and be taken care of. Years ago, health care wasn't available to everyone. Somepeople 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 notfor 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.
People are also living longer now because of better nutrition. We 're eating better and morehealthfully than we used to .That's reduced the number of people with heart disease andcancer. We try to eat low-fat foods and eat more vegetable and fruits ,which are now availableyear-round.
Improved medical care and healthy eating habits has greatly expanded our life spans. Whatwe need to do now is make sure that everyone in the world has these benefits. |
