Being of the same or similar religious persuasion as PaPa I too am free of the assorted hangups. When I go, chuck the remains on a fire in a hole whatever, I don't and won't care, I'll be gone.
However the manner of my going is of more concern. I've seen far to many old folk clinging to life, unable to do anything for themselves. My mother in law, a fit, active, fiercely proud and independent, 85 year old, suffered a massive stroke which left her alive, just, and with very limited movement or mental capacity(?) she had to be nursed night and day which would have been the ultimate indignity for this woman.
Having know her for many years I know what she would have wanted and, sadly for us, mercifully for her she only survived for a matter of weeks. The living will and my families knowledge of my wishes will I hope ensure I don't go through that.
Voluntary euthanasia? fine by me, just so long as the appropriate safeguards are there. We put animals down to relieve their suffering, yet allow our loved ones to linger on, sometimes for years in extreme discomfort so there has to be a case for "pulling the plug" also, although again with appropriate safeguards.
