Will You Live to See 90?

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 reached 81).
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, 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 the  hell do you want to live to 90?
