you start off with a structure
the bones
and the bones are covered
by flesh
and flesh is covered with hair
and freckles and things like
ears and eyes and a mouth
for hearing
seeing
and breathing

and then you get into deeper things like
the lungs and heart and various organs
and the brain somehow controls all of this

every thought you've ever thought
every dream you've dreamt
it's all happened
inside of an ***** no larger than your two fists
put together
so when they say that it's all in your head
they're telling the truth
