Will I Live To See 80?

I recently picked a new primary care doctor. 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?

"Do you smoke tobacco, or drink beer or wine?"

"Oh no," I replied. "I'm not doing drugs, either!"

"Do you eat rib-eye steaks and barbecued ribs?"

"No, my former 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 said.

"Do you gamble, drive fast cars, or have a lot of sex?"

"No," I said.

He looked at me and said,...

"Then, why do you even give a shit?"
