I've not read the entire thread but to me, this is akin to abortion. If YOU don't want assisted dying, then don't have it, but don't you dare tell me what I can and can't do.
I have watched my father die of terminal cancer in screaming agony. At least it was mercifully quick (a few months) compared to watching my mother die of dementia over a decade.
I want to live in a country where I can make an advanced decision - now - that at the point I get dementia (if I do), then as soon as I cannot live alone/recognise my loved ones/lose continence/[insert other criteria], that I'm given life-ending drugs. I can make that decision decades ahead of time. There is no-one to coerce me. I shall talk to my GP on an on-going basis, make the decision collaboratively and have it recorded.
As it is, if I get a dementia diagnosis, I shall have to get on the first plane to Dignitas and end my life whilst I still have the capacity to do so, nevermind that I could still have a good few years left in me.
I will NEVER go into a care home. Absolutely no way. I will not go through what my mother went through. It was horrific and I will never get over the indignity she suffered, being without speech, without cognition, unable to walk, doubly incontinent and spoon fed mush.
So if you don't want to choose assisted dying, then don't. But don't argue bullshit about palliative care being improved. I do not want a decade of palliative care as I lose my mind, thank you. I want to exit stage left, quickly and with dignity.
