I grew up in a world that some people might consider a paradise. Or was it more like hell? In any case, I was regularly surrounded by naked strangers. Sometimes I knew these encounters were coming my way, while other times they took me by surprise.

The scene was Europe in the early 1970s. I can remember long-haired students running naked through the streets of West Berlin, my home town. These “streakers” were so fast that those in the vicinity only glimpsed them for a moment. As far as I can recall, the streakers’ physical exploits were not tied to any political agenda. I think they simply enjoyed shocking or provoking people by intentionally pushing boundaries – but I was too young to have an opinion about it or even find it all particularly interesting.
