I think thats probably true for everyone but sadly and I think in most cases it doesn't happen. I had to watch my Mother dying of cancer she just lingered on and on with the doctors constantly feeding her painkillers and god knows what else. It was pointless. An exercise in futility. All my sisters I wanted to do was turn off the machines and stop the flow end the whole ridiculous sham and just let her go with what was left of her dignity. My lasting memory of my mother is not my mother just some grey husk struggling to breathe through chemical induced existence.
Yes, this is I call prolonging death, not life. just a few weeks ago, I was given a wake up call when my blood tests showed extremely elevated measures in my liver. Being a cancer survivor already, it was an extremely bad sign, and for a few days, the likelyhood of having to face a cancer of the liver was very real. It helped me clear up my feelings about an eventual death. . .until a cartscan showed there was no sign of cancer.
Instead, I was diagnosed with toxic hepatitis, probably due to an intolerance to some antibiotics I was taken at the time. I was told that my liver would go back to "normal" within a few months, probably without permanent damage.
All that to say that, faced with a slow and painful death, I was very glad that, in the country where I live, the right to die a dignified death is in place, and I started the paper work to choose euthanasia if/when I was faced with such a death.
I am sorry, Scotsman, that you had to witness your loved one's painful and long death. I worked as a social worker with people with AIDS in the 90's, when AIDS still led to death, before it became more of a "managed" lifelong disease. Although none of my loved ones were among my clients, I felt the pain of those clients, and the few families who chose to not abandon them (as many had!). I so wish they had a choice at that time in central California to have a choice between the long suffering (emotional as well as physical) and euthanesia.
