In your humble opinion, I'm sure.
I may not agree with your humble opinion however. I am in a geriatric specialty too though it's far from pulmonology or internal medicine. Nonetheless treating on average 80 geriatric patients a week I know better than to believe my dad's case is "the exception."
So what percentage of patients diagnosed as terminal do not die within 6 months?
And what percentage of patients in a similar condition as your father’s condition make it another 6 months?
