I'd like to echo Herts Ambo Bloke, a cracking rant fallen angel, please don't stop, in fact please blog it and tell what it's like, for real. My mums neighbour has dementia, every day she goes (as she has done for the last thirty years, to my knowledge,) out walking in the hills, no one ever has a clue where she has gone, or where to start looking for her if she wasn't home by dusk. This worries my mum, but I think more power to her brogues and cagoule, if something were to happen to her, it would not be such a bad way to go.
