Also, I love sdn forever for this.
Also also, my left shoulder is killing me. I have an old injury, a bunch of scar tissue, bursitis, and a tendency to copyedit with my left elbow on the desk and my forehead resting on my left hand while I green-pencil with my right hand.
I also do this while playing mouseable computer games.
Bad bear. Bad.
