My parents are reaching the same point, only with positions swapped - my father with dementia, my mother in incessant hip and other pain that has no cure. They are both researching options, frustrated that the Canadian MAID program offers neither a dementia option nor a couples option.

And as their eldest, it is my duty of care to implement whatever choice they make. They took care of me in the beginning, I take care of them at the end. And choice is the most powerful gift I could possibly help them retain.
