I've discovered that there's a community called lifein1973 - I'd hoped it was some kind of support group - I even wondered for a moment if I'm not the only coma patient stuck here. It doesn't seem to be exactly that, but maybe it'll have some useful tips for living here. Now. Whatever. I've joined, anyway.
(The people who post in it seem to know a scary amount about my situation... is it a conspiracy? A message from the future? A very bad joke? And I thought it was bad when it was just the telly and the radio talking to me...)
