Dr. Tony Gardner (born 10 January 1964) is an English actor and doctor. He qualified as a doctor at Guy's Hospital in 1987, then as a general practitioner in 1993. He combined medicine and comedy during the 1990s as half of the award-winning comedy duo "Struck Off and Die" with Phil Hammond. Using only the above description and what you know about the world, "Tony Gardner worked as a GP in 1992." is definitely correct, incorrect, or inconclusive?
