Our World In Medicine

    One of the most important factors about people's lives is the
information of, the use of, and the growing knowledge of medicine. Medicine is
a science that nations all over the world use. It is a science because it is
based on knowledge gained through careful study and experimentation. Medicine
is also an art form because it depends on how skillfully doctors and other
medical workers apply their knowledge when dealing with patients.1
    Medicine is one of the most respected professions. The two important
goals of medicine are to save lives and to relieve suffering, which is why it is
so respected. But the medical field is not open to anyone who wants to help.
It takes many long years of college and medical school to get even a license to

    Prehistoric people probably also discovered that many plants can be used
as drugs. For example, the use of willow bark to relieve pain probably dates
back thousands of years.4 Today, scientists know that willow bark contains the
important ingredients that is included in making aspirin.
    In the Middle East, the Egyptians began making important medical
progress. Around 2500 B.C., Egyptian physicians began to specialize. Some
physicians treated only diseases of the eyes or teeth. Others specialized in
internal diseases. Egyptian surgeons produced a textbook that told how to treat
