I recently picked a new primary care physician. After two visits and exhaustive lab tests, he said I was doing "fairly well" for my age. A little concerned about that comment, I couldn't resist asking him, "Do you think I'll live to be 80?"
He asked, "Well, do you smoke tobacco or drink beer?"
"Oh no," I replied. "I've never done either."
Then he asked, "Do you eat rib-eye steaks and barbecued ribs?"
I said "No, I've heard that all red meat is very unhealthy!"
"Do you spend a lot of time in the sun, like playing golf?" he said.
"No, I don't," I said.
He said, "Do you gamble, drive fast cars, or fool around with sexy women?"
"No," I said. "I've never done any of those things."
He looked at me and said, "Then why do you care if you live to be 80?"
