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 sixty-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?

Joking aside, it's a fair point.
