How much time do you have once the trap opens to realize life is done. I suspect you know it while waiting for the trap to open. When I watch the hanging scene in Dadah is Death, I think of those two Australians with the hoods over their heads being led to the gallows and then cuffed and standing there. When did they realize their life was over - was it when the hood went over their head? Was it when they reached the gallows and were turned to face the front? Was it when they felt the cuffs on ankles and wrists? Or was it when the noose was slipped over their heads. To watch them breathing heavily as they wait for the drop, they know they are dead but don't know yet wheat the breaking of the neck will feel like.
