A 75-year-old man went to the doctor for a check-up. 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 75-year-old responded, "Who said he was dead?"

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

The 75-year-old responded, "Well, he is 93 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 75-year-old responded again, "Who said he was dead?"

The doctor was astonished. He said, "You mean to tell me you are 75 years old and both your father and your grandfather are alive? Is your grandfather very active?"

The 75-year-old said, "He goes skiing at least once a season and surfing once a week during the summer. Not only that," said the patient, "my grandfather is 112 years old, and next week he is getting married again."

The doctor said, "At 112 years old, why on earth would your grandfather want to get married?"

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

A reporter was interviewing a remarkable man, who at sixty-five had just run the Boston Marathon. "Oh, it's nothing really, compared to what my father just did," the runner told him. "He's ninety and he just swam the English Channel. Right now he's in Arkansas being best man at my grandfather's wedding. Grandpa is 114."

"That's absolutely amazing," the reporter said. "You're sixty-five and a marathon runner. Your ninety-year-old dad just swam the English Channel. And now your grandfather, who's 114, wants to get married."

"That's not quite right," the runner said. "Grandpa doesn't want to get married -- he has to!"
