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 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?"
