I am back in Zurich. Will start writing about this in a few days. I have lots of pictures.
I also have interviews with (and pictures of) former slaves and some pictures and reports on medical cases.
Tess, thank you. But it wasn't courage, it was suicidal insanity. I knew what to expect but I never expected to see what I knew. Lots of insects. no toilets but smelly and insect-infested (and lizard-infested) drop holes, heat, heat, heat and, quite logically but still utterly surprising, lots of absolute darkness. There are no lights there. It's near the equator. From 7 to 7 there is just DARKNESS. Try finding (or using!) the drop hole at night. I didn't eat for days.
And there is fear. Fear of the darkness, the animals (mostly insects), the heat, the fact that the heat can get worse, fear of not being able to breath the dusty hot air for enough days, and fear of not finding any water that isn't even hotter than the air. Even "showering" in the early morning was an exercise in avoiding hot water. I don't know how people there can live like that.
We live in paradise.
