Will I live to see 80???

Will I Live to see 80? 

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 30-something.) 

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 a Lots of sex?' 

'No,' I said... 

He looked at me and said,.. 

'Then, why do you even give a shit?
