When I Am Exhausted

When I am exhausted but not yet ready for bed I flip myself upside down letting blood come to my head Inverting myself like a moth, or a bat Ideas come quickly, all succinct and pat. When I am tired, I know what to do. I hang from a limb after I take off a shoe. The blood comes to my brain and gives me new thought. It is something I learned by myself, without being taught.
