Additionally, the good doctor did not consider what an engineer would: the force that the body itself is exerting on the table/scale. Part of the reason some people feel that a dead body becomes heavier - hence dead weight - is because the live body is still exerting a lot of effort lifting itself. A dead body obviously doesn't do this. A body dying on a scale will constantly fluctuate in weight depending on whether or not the body is struggling to survive or dying calmy. Consider that it is possible to stand "heavily" on a scale or seems heavier on a scale if your are shifting your weight.

Anyway, I really can't believe I'm arguing this since the "time of death" argument hasn't ever been answered. What about those people who have been "dead" for minutes and are revived - did their souls return? or did their souls never quite leave? And how did they know?
