As I write, attached to each of my nipples is an alligator clip. These clips are connected by wire to a foot operated button switch, thence to twelve volt car battery placed unassumingly next to my PC.  For technical officianados  my left nipple is positive, my right nipple is negative. The reason for my present condition is a tendency to digress from the task at hand at every opportunity when work of some kind simply must be done.  Concentration is my grail in an attempt to combat an attention span rightly compared to that of a goldfish.
