I could work on something. I'm not sure how much I can learn to do in a couple of days. I lost the arm 70 years ago, but until a couple of weeks ago, I had a really comprehensive prosthetic device that I couldn't remove. Well. In a way, I guess I could have always removed it, since someone did successfully blast it off. But it wasn't the sort of thing you could remove and reattach.
Keep forgetting it's not there. Although I guess I won't forget much now.
