Listening to Radio 4 just now I heard a programme on noses. I wasn't really interested as I was putting a meal together but one of the speakers said that Alzheimer's sufferers loose their sense of smell. If only I'd known that before. No wonder mum couldn't smell the gas escaping when she'd failed to light it yet again. And now I understand why she liked the hyacinths which used to drive her crazy with their scent..and left me gasping for breath because in the past we used to both suffer together, however much we liked the look of them and had to put them out of the room!
