It is one of the weirdest body modifications I’ve ever seen. An on/off switch was attached to Dominic Wilcox’s head in 1996. Here what he says: ‘The switch was worn day and night for close to a month. I remember after leaving the place where it was done I had to overtake some people on the path. I knew they would see it, so that was a big moment, then after that I relaxed a little. I went into a pub once and ordered a drink. It felt like the music and pool balls came to a stop for a second or so. Then started up again.
