Yesterday, while watching Madonna at Wembley, the stadium was pin-cushioned with thousands of tiny points of light. This time around the light sources were mobile phone screens. Thirty years ago, when I started attending concerts in earnest, I saw the same pin-cushioning. In those days the light sources were cigarette ends. There wasn’t a cigarette end to be seen at Wembley yesterday.
How times change.Â Or do they? As happened with cigarettes, mobile phones emit light at concerts, are habit-forming and appear to have the capacity to make people ill.
