It's OK, I'm still here. Just busy surviving at the moment. Got a bit fed up just eating meat, so tried experimenting with various roots that I found, and some leafy plants growing near a stream. I was then very ill for a couple of days. Still feel weak. Have had a bit of time for thinking, though, and have some ideas about what got me here. Realise that I also promised to give more background to the whole project. Will try to write more in a few days.
