I was trying to teach in the Tate when this began. We were greeted by a health and safety adviser when we arrived. As we passed, for various reasons, through the bowels of the Tate 'back stage', with relays of sweaty runners under our feet and we under theirs, I warned my students not to touch 'the art works'. The sprinters, some of whom were clearly swifter and fitter than others, were under no illusions about the absurdity of the exercise but then, they were being paid quite well to trot back and forth.
