The Doctor (Doctor Who)
The Doctor is the title character in the long-running BBC science fiction television programme "Doctor Who". Since the show's inception in 1963, the character has been portrayed by thirteen lead actors. In the programme, "the Doctor" is the alias assumed by a centuries-old alien—a Time Lord from the planet Gallifrey—who travels through space and time in the TARDIS, frequently with companions. The transition to each succeeding actor is explained within the show's narrative through the plot device of "regeneration", a biological function of the Time Lord race that allows a change of cellular structure and appearance with recovery following a potentially fatal injury.
World Doctors Orchestra
The WDO currently includes a pool of 1.211 physicians (49% women and 51% men) from about 50 countries. They are all medical professionals and, at the same time, are enthusiastic and active musicians, many of them with a professional musical background. About 100 members participate in each concert, depending on the availability of the members and the instruments needed for each concert. All important instruments are represented. About one third of the members are professional musicians, the others are excellent amateur musicians who engage in regular musical activity as well as practicing medicine. About 27% of the members play in professional orchestras in their free time, whereas others play regularly in non-professional orchestras and chamber music ensembles. A great variety of medical specialties are represented. Pediatricians, internists and general practitioners take the lead, and there is a wide variety of specialization in diagnostic and therapeutic areas, as well as in pharmacology.
