forces

forces can't be created nor distroyed.
they are just merely changed into another kind of force.
so, weight is force. weight = force.
so, weight can't be created nor distroyed.
it's just changed from one form to another.
in this case, the total amount of weight on earth does not increase or decrease, it's just transfered from one person to another.
meaning. if one person on earth looses weight, one gains. therefor the amount of human weight on planet earth will always maintain the same. how depressing =(
