Assisted dying aside, what I do think there is too much of, is ‘striving to keep alive’. My DM was in her (dementia only) care home for her final 8 years, so I saw quite a bit of it, though not for her, since past a certain stage, family wishes for her welfare were made very clear. TBH we thought it would be verging on cruelty to try to prolong her life, given the pitiful state she was in.
But a lot of it did go on with others - in and out of hospital, on drips, stuffed with tablets for this or that to keep them ‘healthy’ - for what?? Not to mention people being badgered to eat and drink (albeit with the best of intentions) when they no longer wanted to.
From all I’ve ever gathered, the ‘striving’ is often at the insistence not of medics but of relatives, who are outraged/terribly upset at any suggestion that it might be kinder to let nature take its course, and give palliative care only.
Possibly the most extreme case I heard of was of an over 90 year old with at least moderate dementia, who was fitted with a pacemaker. This despite relatives being told that without it, s/he would very likely just drift away in their sleep. But no, the relatives wouldn’t hear of that, and it was their choice, for a person who no longer had the mental capacity to decide for themselves.
