England is old and small and the local folks started running out of places to bury people. So they would dig up coffins and would take the bones to a bone-house, and reuse the grave. When reopening these coffins, 1 out of 25 coffins were found to have scratch marks on the inside and they realized theyhad been burying people alive. So they would tie a string on the wrist of the corpse, lead it through the coffin and up through the ground and tie it to abell. Someone would have to sit out in the graveyard all night (the graveyard shift.) to listen for the bell; thus, someone could be, saved by the bellor was considered a dead ringer...And that's the truth...Now, whoever said History was boring ! ! !
