I would like to be a physician because  the profession is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease and others 
Nice ,so what does it take to be one?
It  will  requires you to have  both a detailed knowledge of the academic disciplines  and a decent competence in its applied practice which is the art or "craft" of medicine.
OK what institution offers the course?
Alot across the USA but I like John Hopkins University for it. Also, know that degrees and other qualifications vary widely, but there are some common elements, such as medical ethics 
OK how many years?
I'm not sure but i think it's usually longer than others.  It would interest you to know that  the role of the physician and the meaning of the word itself vary around the world.
So where would you love to work?
John Hopkins  Hospital :) do you that Around the world the term physician refers to a specialist in internal medicine ?
