I think what I'm focusing on is the fact that I think of "myself" or my "self" as being closely related to conscious awareness. So stuff that happens without my conscious awareness and control (like digestion, or my hair growing, or aging...or finding the thought I was looking for, or stopping thinking for a minute), is a part of me, but isn't "me."
Does that sort of make sense?
Peace.
