"Limited to one-arm activity. . ."

Just before the surgery I asked my doctor for a letter to send to my unit because I was (am) scheduled for three weeks of training beginning two days after the surgery. The unit wanted me to observe training if I could, even if I could not participate. So the doctor wrote a letter stating that my full recovery should be the primary goal and I would be wearing a sling for six weeks, but he thought after two weeks I "should be able to ride to the field in a truck." But he made clear: "He will be limited to one arm activity for the first six weeks." I faxed the letter to the unit operations sergeant pointing. He read the letter while I was on the phone and burst out laughing at that restriction. When I do go back to duty I am sure somebody is going to making loud suggestions as to what activities I can do with one arm--and how they will prepare me for next year.
