In the old days medical euthanasia for suffering and for dreadful birth defects was commonplace, mainly unchallenged. Today at birth, MUCH less so, too many are likely to have an agenda of ill placed sensitivity.
Today under suffering the usually diamorphine syringe driver is used, probably the time / volume graph is manipulated differently by different "health professionals", but as a way to normalise euthanasia it's certainly in use. I've got my own morphine supply secreted away and enough knowledge to make a viable syringe driver, hopefully if the worst comes to the worst and I'm compus mentis enough to know when to use it I can make my own decision.
Time for a beer, what a depressing thread, sorry the OP has the dilemma of thinking of and discussing this subject, life's a bitch
