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 90?"
He then asked, "Do you smoke tobacco or drink beer or wine?"
"Oh no," I replied. "I'm not doing either."
Then he asked, "Do you eat rib-eye steaks or barbecued ribs, or any of those types of meats?"
I said, "No, my other Doctor said that all red meat is very unhealthy!"
"Do you spend a lot of time in the sun, like playing golf, sailing, hiking, or bicycling?"
"No, I don't," I replied.
He asked, "Do you gamble, drive fast cars, or have a lot of sex?"
"No," I said. "I don't do any of those things."
He looked at me and said, "Then why do you care how long you'll live?"
