Who am I?

Who I am and what I am here for!!!

At the end of the matter, we all are set of atoms and molecules. The individuality we get is only because of the unique combination. It always amuses me as to how the minor changes in configuration could make so much of a difference in personalities.

Every 7 years all your atoms and molecules are replaced with new (similar) ones. But you still keep your identity.

There has to be more than atoms and molecules to human body and no one knows for sure as to what it is...
