Hahahaa Steve! They could sing, 'Abide With Me' but their poor hands would end up with dermatitis after being washed...and washed...and washed... for the duration of all five dreary, slow verses.
At the Norfolk & Norwich hospital last year, they actually had to use a meat refrigeration lorry parked outside the mortuary door in which to store all the accumulated corpses during the flu epidemic. There was an outcry at the indignity of it, but as you say, one can't leave bodies just lying around rotting slowly away.
