Do you remember doing that weird thing with your arms when you were a young teenager? You know, the trick where you took turns with your friends standing in a doorway with your arms by your side and the back of your hands pressed hard against the frame? You applied pressure for a full minute then released it and stepped from the doorway. Letting your arms go slack you impressed your friends and yourself when your arms began to slowly rise all on their own.
It was as if someone had cast a magic spell on your body, wasn’t it?
