76:5.5

Adam lived for 530 years; he died of what might be termed old age. His physical mechanism simply wore out; the process of disintegration gradually gained on the process of repair, and the inevitable end came. Eve had died nineteen years previously of a weakened heart. They were both buried in the center of the temple of divine service which had been built in accordance with their plans soon after the wall of the colony had been completed. And this was the origin of the practice of burying noted and pious men and women under the floors of the places of worship.
