Doctor, doctor, I think I've found a lump on my testicles!

Everyone knows the timeless 'Doctor, doctor' jokes. They are set in a parallel universe. But did you realise that doctors exist in this universe too?
Yes, if you've ever had a serious accident, such as cutting off your eyes or bursting your knees, a doctor is exactly they type of person you would need to visit. It is the duty of a doctor to help anyone who is in pain - it's the hippocratic oath!

History is full of famous doctors: Dr Socrates, Dr Sherlock Holmes and Dr Dolittle, to name them all. But none of them are the oldest doctor!

The oldest doctor is Dr Pepper, who invented the odd tasting fizzy drink that now bears his name: Fanta.
He is 92.
