Where is it written what the written form of one's title should be?
Is it correct to use the "Dr." _and_ the "PhD" ie Dr Fulano de Tal, Ph.D.
Or Dr Fulano de Tal, O.D. or M.D. for medical types
How much work is involved in getting a "M.D., Ph.D." did these guys do
several years of grad school and research and a dissertation before or
after med school or is this like a J. D. for lawyer types?
