Sorry for the blogs which have been coming one after another but here's a change from my regular which I am sure you will find very interesting. Most people have heard the phrase, 'Graveyard Shift'. This is how it originated:
In the 1500's England was 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, one out of 25 coffins were found to have scratch marks on the inside and they realized they had been burying people alive. So they thought 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 a bell. 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 bell" or was considered a "dead ringer."
I found this quite fascinating but what's more, is every Instructor was absolutely astounded when I told them this. The students now know that Instructors don't just talk about martial arts, they also drink good coffee! Pleasant dreams!
