EDIT: "In what fashion are atoms or molecules added to a body, then attached, how exactly do they get replaced?" http://imgur.com/pmR8RB9 (I realize atoms are much smaller) Sorry for the crudity of my drawing but I think you get the general idea. I can't picture what happens? I believe they stay together through some sort of ionic bonding where electrons are gained and traded, magnetic I suppose. Atoms, as I understand, bond into molecules. But what in the world happens for the atom or molecules to get to all these places in the body, what movements, a shifting?
