So only the core of the apple is the true apple?

If you want another example, say a bread roll. If you eat a bread roll, is it still a bread roll or does it become part of 'I'?

It's a mass of particles the whole time. It's a bread roll when it plays the causal role, or set of such roles, which we term a bread roll. It's "I" when it plays the causal role we term "I".

Sure, but then the question becomes... Where does "I" start and end? For example, the air in your lungs, is that part of "I"? If it is, where does it stop being part of "I"?
