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. 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, wine or hard liquor? '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, boating, sailing, hiking, or bicycling?' 'No, I don't,' I said. He asked, 'Do you gamble, drive fast cars, or have lots of sex?' 'No,' I said... He looked at me and said,.. 'Then, why do you even give a shit?
I've never seen any 80 year olds do those things, except for smoking or drinking. Maybe a little golf... But if I'm doing all that at 80 I'll be pleased.
