Health

My father was a dynamic person who never slowed down until a couple of months before his death. He had asthma/emphysema (never smoked) but that didn't get in the way of playing tennis or vigorous walks. He did suffer from urinary tract blockage late and a botched bladder stone removal. Still kept on plugging. At some point he lost the ability to talk (probable stroke), and just gave up on trying. Was ready to die. His death certificate was COPD.

I guess it's hard to sort out the actual cause when there are so many contributors.
