As we know, our atoms change, atoms are not created, therefore, we are just a recollection of already existing atoms arranged into a human form. This problem begs the question, Are we ever really ourselves?
Perhaps you have some atoms from Mozart, or from Beethoven, perhaps some from MLK. Atoms are passed from generation through generation, the atoms in these figures aforementioned were from someone else's or perhaps they came each little bit from every different human that ever lived. So, who are you? What will you do, so that future generations like me, wonder about having this same exact thought and say: "So I have a little atoms from...(your name here)".
How will you be remembered for the milennia to come? Will you be ever remembered at all? What impact are you going to make?
