I had a similar experience to yours, Yaya, except it was with my middle-aged brother who had advanced, uncontrolled diabetes.
The article was interesting. The thing is, modern medicine DOES often extend a life for too long, but they can also help bring certain patients back from the edge, "healing" them to a degree where perhaps their acute pain is gone, their circulation renewed or perhaps even give the patient a transplant.
It's all a judgment call in the end. It's fine to die at home - if you HAVE a home, and caring relatives - but if you're all alone in the world what really are your choices? Especially when you're racked with chronic pain to the point where you spend your days crying?
