Re. Doctors. I know my dentist actively does clinical research. His day job just involves seeing patients, doing root canals (in my case), but weekends are about research, he's published a bunch papers. His eyes light up every time I'm in the chair, and we have an enjoyable discussion about NumPy, R and the statistical techniques he's using, and the medical papers he's been reading (Well.. naturally with me unable to speak in the dentist's chair, he gets to do most of the talking.) I'm a lay person, so I cannot judge his skill level, but it's obvious he loves his job. His hospital obviously supports his work.
