Yes, I do remember now that you mention it Minniea, being told at some point that they did that (bound his wrists to ankles) in order to pull his shoulders down so as to avoid the radiation. I don't think it is something he can release himself from though, although I don't want to bring it up to him by asking, since he has "accepted" it the way it is, and if it can't be changed, I don't want him to think about it any more than he has to. It still seems like there should be a better way, such as what you describe Nelie.
