You hang around people long enough and you learn their tells. Pain has a way of exiting the body, and most will let you know when it's on its way out. Seldom do they know what their "tell" is telling you. Most often it's silent. Sometimes it can be loud. However it comes out, it leaves a trail. Jittery fingers. Itchy skin. Headaches. Always tired. Always hungry. There are hundreds, I guess.
