MR. RENSBERGER'S EXACT MEASUREMENTS keep changing what caution held in check swells out again also he moves around so it is hard to be precise his skin flakes he takes a drink his eyes sparkle is any light lost? if I were him I'd carefully match breath in to breath out year by year the memories grow longer but he will not allow them to be paired against a ruler it's impossible his losses and gains seem to even out but there may be a remainder that escapes notice his motion continues even in sleep he does not need wakefulness evidently to wriggle free what falls off is lost forever but the off and the forever might be recorded as a gain while what is lost weighs heavily but at what weight exactly?
