DOES THE HUMAN BODY LOSE WEIGHT AT THE MOMENT OF DEATH?

Do you believe that the human body loses weight at the moment of death? It is belief made popular by the 2003 film, 21 Grams, based on the experiments of Dr. Duncan "Om" MacDougall (c. 1866 – October 15, 1920), who also killed a dozen dogs during his research. However, the "good doctor's" results were never duplicated and his methods unable to produce consistent results. Supernatural claims are a dime a dozen; don't be duped. http://en.wikipedia.org/wiki/Duncan_MacDougall_(doctor)
