I am without Internet while visiting family but wanted to pass along a note from Bob.
"Please rest assured that we are not trying to avoid commenting on Dad's status.
We are continuing to contact and discuss his condition with experts and carefully considering our options. His shoulder and elbow injuries are, after all, serious and we do not want to rush to a decision.
I spoke to Jo last evening and she reported that he is doing well, eating well and behaving calmly. That makes the aforementioned contacts and discussions easier in the sense that we do not have to hastily reach a hard decision as to Dad's fate right now."
