Will Self muses on change as he prepares for a stem cell transplant, an operation 'which will result in the greatest change in what has been a notably changeable life.' And he discusses the preparations he's making which he believes put him 'in pole position to race with this ...devilish adversary.' He concludes that the art of living is about recognizing that 'life is in continual flux - and our vacillating wills and changeable natures, psychic and physical alike, are just part of the cosmic churn - nothing in fact endures, but change itself.'
