I feel very privileged to live in a country where assisted dying, with very carefully drawn safeguards, has been legal from the 1940s.
I am a member of Exit here in Switzerland, and my wishes and living will are all known to my OH, children, GP and sollicitor. The big hurdle now for Exit to conquer, is to find ways to allow assisted dying for those affected by dementia or Alzheimers, as even here you have to be of sound mind not only at the time of decision, but also on Exit day. This is totally unfair, as it still forces people to end their life too soon - when still enjoying their family, friends and other joys- as otherwise it might become too late.
There should be a way to make a living will which will state exactly at what stage Exit should come and help end the misery and total lack of dignity. Perhaps a list of 5 criteria, which, when reached, should automatically lead to Exit- chosen in advance by the member. For me that would include
when I no longer recognize my OH and children
when I no longer show any joy or pleasure when above visit me
when I become totally unaware of my body functions and exhibit degrading behaviour related to such (my mil used to smear excrement in her room and wash her false teeth in the toilet- her such a proud woman)
when I no longer enjoy the sun on my face or birdsong
