hello all. back in early eighties in some random sci fi anthology. basic outline is Earth all frozen and deserted. A man wakes up as he is being moved from a regen pod to a rescus slab. he is being dragged by countless generations of bio engineered slave mice who keep dying from his body heat blasting them and others jostling to take their place on the haulage cords. once he is on the slab lots of tubes and wires connect as he comes to full awareness. at this point he looks at his body and realised THIS TIME he's almost full size. he looks at badly cracked weather dome above his roof and notes that he must still be at True Bath. A pharaoh mask (?) with traditional protruding tongue lowers onto his face and interconnects with his nerves to transmit some kind of warning. then he gets up and moved to window and looks upon the frozen wasteland. instantly his body temp attracts a 'tourist' who comes closer but unfortunately just as he sounds (?) and the tourist is killed by a wave of nostalgia. the death sets off alarms in massive Earth monitoring space station and the A I , named as Dr Mobious, hastily dispatches a snatch squad.the A I hurriedly checks it's systems and wipes out the rogue worm security programme that allowed this regen without sounding the alarm. back on Earth the man, now identified as Nicholas, is warned by a robot mime about the squad hurtling down . they arrive too late as he is already moving back through time. anyone ever read this? I was told on another site some years ago that this weird short was actually expanded into a full book and the short formed opening chapter. however my correspondent couldn't name it either. he stated it was in a yellow cover "like Gollancz dude"
