21 Grams

OK, this is not an original piece. But I have wanted to share this monologue ever since I saw the movie.
21 Grams is basically a stark description of death and life. And everything in between. The following is a monologue at the end of the movie. I am not sure if it would mean much to those who have not seen the movie. But if it does, even a little, do watch the movie. Here it is:

How many lives do we live?
How many times do we die?

They say we all loose 21 grams at the exact moment of our death. Everyone.

How much fits into 21 grams?
How much is lost?
When do we loose 21 grams?
How much goes with them?
How much is gained? How much is gained?

21 grams.
The weight of a stack of five nickels.
The weight of a hummingbird.
A chocolate bar.

How much did 21 grams weigh?
