Here's something to think about.

    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 had just turned 65)  A little concerned about that comment,
    I couldn't resist asking him, "Do you  think I'll live to be 90?"

    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 damn?"
