How does a person get into a fetal position after rigor mortis sets in?
Funeral directors would have more work playing with a dead body.
Does he curl the body for the wake or after?

Bodies would be buried every fifteen to thirty feet instead of side by side.

Dunno...the curling of the body seems a very natural form.....completing the circle of life.
