I know that this is on aging but I relate to the man who cared for his father who died after 5 yrs of caretaking. I was the primary caretaker for especially the last 6 yrs as he was mostly home and had challenges. I watched and didn't call 911 unknowing what was going on and blamed myself for I thought I knew what was wrong but I didn't know everything. I didnt know it was going to be fatal.
