A 60 year old man went to the doctor for a checkup. The doctor told him: "You're in terrific shape. There's nothing wrong with you. Why, you might live forever. You have the body of a 35 year old. By the way, how old was your father when he died?"

The 60 year old responded: "Who said he was dead?"

The doctor was surprised and asked: "How old is he and is he very active?"

The 60 year old replied: "Well, he is 82 years old and he still goes skiing three times a season and surfing three times a week during the summer."

The doctor couldn't believe it. "Well, how old was your grandfather when he died?"

The 60 year old responded again: "Who said he was dead?"

The doctor was astonished and said: "You mean to tell me you are 60 years old and both your father and your grandfather are alive? Is your grandfather very active?"

The 60 year old replied: "He goes skiing at least once a season and surfing once a week during the summer. Not only that, my grandfather is 106 years old, and next week he is getting married again."

The doctor asked: "At 106 years old, why on earth would your grandfather want to get married?"

His patient looked up at the doctor and responded: "Who said he wanted to?"
