Doctor Simon is known as one of the best consultants on arthritis. He always has a waiting room full of people who need his advice and specialist treatment.

One day, an elderly lady, slowly struggles into his waiting room. She is completely bent over and leans heavily on her walking stick. A chair is found for her. Eventually, her turn comes to go into Doctor Simon's office.

15 minutes later, to everyone's surprise, she comes briskly out of his room walking almost upright. She is holding her head high and has a smile on her face.

A woman in the waiting room says, "It's unbelievable, a miracle even. You walk in bent in half and now you walk out erect. What a fantastic doctor he is. Tell me, what did Doctor Simon do to you?" "He just gave me a longer walking stick."
