My back hurts. It does that sometimes, and when it does the ache plays hell with any plan to sit and/or concentrate for more than a few minutes at a time. So I get up and down and press my hands against my lower back (a firmly established medical principle by the way). Any attempt to focus and thus distract does not go well.
Quite a shame since I had so much bloggy brilliance building up inside me. It was all scheduled to burst forth this very day! But my back hurts.
