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 (I just turned 60). A little concerned about that comment, I couldn't resist asking him, "Do you think I'll live to be 80?"

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

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

Then he asked, "Do you eat rib-eye steaks and barbecued ribs?"

I said, "Not much... 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.

He asked, "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?"
