Why you might be infinite

Every day you inhale billions of new atoms and breathe out or shed billions of old ones. You are not defined by the atoms in your body but rather the pattern in which they are arranged. If these are the paths taken by atoms over time, a box indicates a person's lifespan but maybe you'd rather think of your box extending back to include the atoms that would become a part of you and forward into the future to include what you might become. So in that way, your pattern could be considered never ending.
