How much do 21 grams weigh?

They say we all lose 21 grams at the exact moment of our death.
Everyone.
And how much fits into 21 grams?
How much is lost?
When do we lose 21 grams?
How much goes with them?
How much is gained?
Twenty-one grams.
The weight of a stack of five nickels,
the weight of a hummingbird,
a chocolate bar,
How much do 21 grams weigh?

One of the mornings, you call...

I am in the middle of nowhere,
you are far away of the reachable,
suddenly, I decide to have no one, nor you, nor him, nor anyone.
I have myself,
either a sad being or a happy being,
or a good being or a bad being,
I have myself.

Maybe there is some one who loves you more than me,
I am sure that my love to you will never less than her.
