We are all recycled humans - the atoms and molecules in your body will go thru nature and be reused... some of what you are made off may have been part of a cow, a little spider, a tree, a roman gladiator, a french politician etc. - and when you die, and your body either rot or burn, then some of your atoms might end up in some other humans - ex. in socialists, republicans etc.
Actual most of your body recycles every 7-10 years, so who knows where "you" will be in 10 years time, and where your new body have been before...
Now thinking we got a soul, which stays with us no matter what changes is done to our bodies, and which we take with us when we die is kinda of a interesting theory, but just like humans killed God, because we had no use for him, then I think there is a slime chance that we once in the future will be reading "Soul is dead" by a person who consists of parts of Nietzche´s atoms...
