I don't know that Diaboli guy but there is one picture in the "Czech Eden" book in which his look-alike still has all his hair and even a beard. In all the other pictures he is all bald like in the picture where he is standing in the water with his girlfriend holding (I assume) their child. As I said at first I didn't even realise it's the same person. When I did, this conjured up fears of cancer, illness etc. Some general uneasy feeling that can also be felt in some other pictures. Yet he looks like he's alright with how he looks, leading a normal life. I think that was interesting.
