Thanks a lot. We have a foreign teacher from Uganda in my present school who told me something differnt from what you mentioned. First, if I were sick, I would go to see a doctor in a hospital who would tell me what kind of disease I suffered and then would give me instructions and would tell me which physician I should go to. And she told me that a physician is different from a surgeon. What a doctor does is general while a physician is detailed and at the same time a physician earns more money because he/she works under a lot of pressure. And she doesnot know anything about surgeon. Unfortunately,I have a cold now.Thanks.
