You have eyes in the back of your head.
Well, maybe not eyes,
Without the eye brains,
The eyes are no use,
And those eye brains
Are in the back of your head.
Look through the eyes on your face
See the world narrow but bright.
Look from the eyes at the back of your head,
Watch from your spine
The world opens up,
Perhaps less precise,
See with the eyes at the back of your head
And your forehead relaxed.
