Sort of on topic... my Step-Dad had a massive heart attack with emergency Quad By-Pass. Which then developed into polymyalgia and Farmer's Lung. He never came out of that situation the same man. He went from a Volunteer fireman/Farmer.... to a very weak man, who spent the 1st 2yrs of recovery almost bed ridden. His quality of life was never the same, and he hated it! (not to mention the horrendous medical bills and pills that came along with all this) At the time of the surgery, doctors informed him, that the typical by-pass surgery was only good for about 10yrs.
The 10yr mark hit, and his daughter was begging him to go back to the doctors and see what could be done for him. He refused. On the 12th year, he had another heart attack. While in the ER, the family attending to his side, his daughter wept, "Dad, why didn't you go back to the doctors like I begged you to?"
His answer was, "because I'm sorry I agreed to it, the 1st time". And then he died.
