I imagine this uniqueness defines each one of us i.e. my particular combination/permutation is me. — TheMadFool

I guess what I am wondering is these permutations and combinations of the genes and elements cause my body to maybe produce more of one chemical and less of another, just like how programming affects what a computer does. But they are not self-aware. My computer is unaware of itself, as is my phone, they don't know that they are who they are. How can I?
