Do you think I'll live to be 80?!

Do you think I'll live to be 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?"
He asked, "Do you smoke tobacco, or drink scotch, 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, "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 ride a chopper ,
"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 sh*t?"

Living to 80 is up to Chuck Norris to decide.
