In the movie "21 grams", it was said that one loses 21 grams of his/her weight exactly in the moment of death.

Is this true?

Is this amount of weight loss (21 grams) independent of person's physics, gender, etc?

    'Do we lose 7 pounds when we die' is not really the same question as this. For a start, the amounts are vastly different, and also the stipulation of this question that it should happen at the moment we die. FWIW, the answer is almost certainly no. Commented Aug 1, 2014 at 11:22

    @Owen both questions are about what happen "when a person dies", not later on. The answer in the other question addresses the 21g amount as well.

  • 21g the instant you die is the 'canonical' figure. The 7 pounds version has been twisted along the way.
