A colleague of mine recently visited a primary care physician. After two visits he was told he was doing "Fairly well" for his age.
A little concerned about that comment, he couldn't resist asking the doctor, "Do you think I'll live to be 80?"
The Doctor asked him, "Well do you smoke tobacco or drink beer/wine?" "Oh no he replied. "I'm not doing either"
The doctor then asked, "Do you eat rib-eye steaks and barbecued ribs?" he said, "No my other doctor said 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" he said.
He was then asked, "Do you gamble, drive fast cars, or have a lot of sex?"
"No," He said. "I don't do any of those things."
The doctor looked at him and said, "Then why do you give a shit if you live to be Eighty.
