@JustinDerrick And yes having my remaining grandmother visit me and not know who I am is a kind of pain that is quite unforgettable.
She is otherwise happy on most days, and able to remember most of her family; it's mainly just the grandchildren who she has forgotten. It will get worse.
She will die not knowing her own identity, if it gets to that.
Senile people everywhere will die sooner, if laws like this pass. Their relatives will demand it.
