> why am I digesting my food and not yours

haha :D

To take it a bit further, I am not sure if the first question makes a lot of sense either.

I think the first question does make sense. By the same analogy, asking what is digestion precisely and how the stomach digests food is perfectly sensible.

I would also note that the second question can make sense, but only if you believe consciousness is not strictly tied to the brain and body.
