Mostly you can only be your head right? However the existence of your own head is questionable. Can you be your foot? Like when you smash your toe because it’s dark and the bathroom door is closed but normally it’s open so you assume it’s open and you walk confidently through the doorway only to smash your toe into the door and then other parts of your body too kind of. Are you then all those parts? Can you be? Are you back to being your questionable head when you’re like why is this fucking door closed inside your head while your mouth kind of whisper-yells ahh shit. Are you the clatter that wakes up your wife? It was sound that did it but you will ask did I wake you up? But you don’t have any choice in the matter because you had to go to the bathroom in the middle of the night who was that poking at your bladder? Your head says you’re not the first to wonder these things so who is the idea of wondering about this? It’s an information. Like an integer. Who is four?
