" Empires die, like all of us dancers in the strobe-lit dark. See how the light needs shadows. Look: wrinkles spread like mildew over our peachy sheen; beat-by-beat-by-beat-by-beat-by-beat-by-beat, varicose veins worm through plucked calves; torsos and breasts fatten and sag...as last year's song hurtles into next year's song and the year after that, and the dancers' hairstyles frost, wither, and fall in chemotherapeutic tufts; cancer spatters inside this tarry lung, in that ageing pancreas, in this aching bollock; DNA frays like wool, and down we tumble; a fall on the stairs, a heart-attack, a stroke; not dancing but twitching...They knew it in the Middle Ages. Life is a terminal illness. "
