This week we will explore the profession of medicine as seen in physicians, we will investigate other health professionals.

"There are two kinds of practicing physicians in the United States: allopathicphysicians (MD's) and osteopathic physicians (DO's). Both are fully licensed physicians, trained in diagnosing and treating illnesses and disorders, and in providing preventive care."

What's the difference in training time? education? cost? and actual practice of these two kinds of physicians?

Do you prefer to see one or the other? Why?
