I am sure the body loses 21 grams when the body dies and nobody is sure why ...there was a alleged experiment taken out numerous years ago where a doctor with consent of the patients monitored them as they was terminally ill and close to deaths door, apparantlyy they was put on a metal bed which was weighed with the patient throughout the process so any body fluids would also be accounted for and as soon as they passed away the weight loss was 21 gramms, no more no less but nobody could account for this and it is christian belief that its the soul leaving the body. Was a film made by tarantino called 21 grams based on this ??
