Haven't rtft so perhaps these points have been made already but ...
In the NL you can specify ahead of time that you receive the final injections at a certain point in your life. They won't, iirc, let you go to the End of Life clinic unless you are ill - there is always a medical assessment of this.
Being the Netherlands, once the assessment is made the end of life team can arrive very quickly. I've known a few take this choice. One marvellous man I knew was in end stage cancer and he decided after one terrible night that it was his time. His wife respected his choice and by the mid-afternoon the assessment had been made and the end of life team had come and administered the injection.
There was a case here as @OutofEverything said where someone with dementia, who had left instructions for the end-of-life team to come at a certain stage, actively fought it when the set conditions were fulfilled as she had lost all awareness of her 'own' will. The family, who sounded loving, said for the team to go ahead because the woman had been very clear when in her right mind that it was what she wanted. Her earlier stated wishes were respected. It went to court and in this very difficult area, the judgement of the team to go ahead was upheld.
Each doctor can refuse to recommend a patient for the End of Life clinic. You can refer yourself if your doctor won't. I'm told that the end of life team are generally a very compassionate bunch (friend of a friend works on one team).
I did hear a debate once in the UK between an informed person and a pro-life person. The pro-life person clearly had some extreme ... issues. He was claiming that in the NL the 'death wagons go round estates drumming up business'. Im not sure what fantasy land he was living it, but it certainly wasn't the NL.
Having said that there are some real and valid concerns about people being pressurized. This is a very difficult area where there are very often no easy answers and people who are looking for them need to acknowledge that. No assissted suicide = condemning people to live in sometimes extreme pain and distress. Assisted suicide = condemning a number of people to relations' pressure to die.
Either way the religious view of 'give your suffering to God' makes me sick, even though I have a belief. It's just cruel. On the other hand there are some rather difficult implications here; in the NL a mother can ask for and receive assisted dying for long established mental health issues even though she has young children. That sits ill with me.
I prefer the pragmatic, sensible approach in the NL where the whole issue is seen as your own choice and giving you the power to decide when to die with dignity, while you still have your own mind. It's not problem free, but it does seem to me like it's the best of an incredibly difficult situation.
I have to ask @NutellaEllaElla
People can live with Dementia for many years before it is those awful things. You're writing off years of good living
what happens when it does get to those awful things? What happens if someone actively wishes to bring their life to a close before it gets to those awful things?
What a disgusting way to speak about humans with an illness.
I don't think this sentimentality has any place in the face of someone in extreme agony who wants to die.
