God I hate packing more than antihyng I can think of right now, except for George Bush. My body seems to have cooperated with me, however. At my (somewhat) youngish age I’ve developed a bad back that prevents me from packing (the repetitive motion) and moving.Somehow, it does not stop me from lifting weights in the gym. There is a rational explanation, of course. In the gym, I use, or try to use, exactly the right form, so I don’t get injured.More cynical Freudian interpretations could be made, but I resist them with the strength of an Exegetical Hell.Best of luck to you, trooper. Better you than me!
