I recently visited my new doctor. After two visits and an exhaustive lab test, she said I was doing "fairly well" for my age.
A little concerned about that comment, I couldn't resist asking her, "Do you think I'll live to be 80?"
She asked, "Well, do you smoke tobacco or drink beer or wine?" "Oh no", I replied. "I've never done either."
Then she asked, "Do you eat rib-eye steaks and barbecued ribs?" I said, "No, I heard that all red meat is very unhealthy."
"Do you spend a lot of time in the sun, like playing golf / sailing / ballooning / motorcycling / rock climbing?" "No, I don't," I said.
She said, "Do you gamble, drive fast cars, or fool around?"
No," I said. "I have never done any of those things."
She looked at me and said, "Then why do you give a feck if you live to be 80?"
