I just happened to read about it in an anthropology magazine one time. Yes, fascinating. If you saw someone with a tattoo of a church roof dome it signified a ten year term, something like that. Your history was on your back. Many of us have had the mixed blessing of a very soft life so far. But who knows what aptitudes we may discover in ourselves as our roller coaster dips towards The Lord of the Flies and starts picking up speed? But if you ever find yourself stepping into a Russian prison, and you see a beautiful lace cloth on the floor in the doorway, be sure to step right on it and grind it slightly into the muck. It’s a test. I learned that one in The Gulag Archipeligo.
