My mother (85) has been in a home for over 7 years - can't speak, can't move. Whenever I visit her, I never know whether she knows me or not.
I can't speak for her but, if ever I get like that, it would be nice to know that, with due provisions, my son would be able to allow me to go without any difficulty. Quietly, simply, quickly, legally.
My dream, of course, is to go out like a light, on stage, smoking a Havana cigar, drinking a large Hennessey VSOP, playing my best guitar, with a chickadee on my knee, to the rapturous applause of an appreciative audience - and have the whole thing filmed and put on YouTube.
