When I died, I had myself buried in a duplex coffin. Saves money, but it was a mistake. I wasn't dead yet, as they lay me in, but I would be soon. They pulled the corpse out, arranged me, then laid it in on top of me, head on my feet, feet in my face. Dying has changed.
Death comes in stages.
It's a gradual process. Then your legs and even sometimes your arms dry up, become just bones. Often they fall off. The last thing you lose is consciousness. Strange that the power to grasp things, to change things, is last.
