Will I Live to see 80?

I recently picked a new primary care doctor.

After two visits and exhaustive lab tests, she said I was doing fairly well for my age.
I am past Sixty Five.
A little concerned about that comment, I couldn’t resist asking her, ‘Do you think I’ll live to be 80?’
She asked, ‘Do you smoke tobacco, or drink beer, wine or hard liquor?’
‘Oh no,’ I replied. ‘I’m not doing drugs, either!’
Then she 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.
She asked, ‘Do you gamble, drive fast cars, or have a lot of sex?’
‘No,’ I said…
She looked at me smiled and said, ‘Then, what’s the point?
