nice picts, mr.onzedge. i just realized i use the same blue pen at work!
ms.bc- sorry to hear about your back. i recommend the mr.gurney back exercise.
lay on floor, legs together, bend knee, then with your back and shoulders on the floor, move bent knee left/right till your knees hit the floor and hold for a few seconds. go left/right 10 times.
i do this as part of my morning warm up and it's been great.
