“Love lasts about seven years. That's how long it takes for the cells of the body to totally replace themselves.”
“Every single cell in the human body replaces itself over a period of seven years. That means there's not even the smallest part of you now that was part of you seven years ago.”
“Every seven years our bodies change, every cell. Every seven years, we disappear.”
“Body cells replace themselves every month. Even at this very moment. Most everything you think you know about me is nothing more than memories.”
“If it's true that every seven years each cell in your body dies and is replaced, then I have truly inherited my life from a dead man; and the misdeeds of those times have been forgiven, and are buried with his bones.”
“Every few years we disappear, Zoey. All our cells are replaced by others. Not a single bit of me is the same as when I was last in this room.”
