Jonathan Miller was a member of the legendary English comedy troupe, Beyond the Fringe. He also happens to be a doctor.
Once, Miller was asked by interviewer Dick Cavett if he jogged.
“No,” said Miller emphatically.
“You don’t?” replied Cavett, surprised. “I’ve heard that jogging adds two years to your life.”
“That’s true,” shot back Miller. “But you spend them jogging.”
