I heard about that when it happened, but hadn’t realised it took nine years with a coma, paralysis, and seizures. It must’ve been horrifying for everyone involved, including the mates who dared him.
Touchy subject and Im not commenting on this specific case that I have no idea about, but for this class of cases (ruptured spine, paralysis, coma) MAID seems better than prolonging life, especially if there’s no hope for full healthy recovery.
