FYI, my father had some health issues Sunday night which required surgery Monday morning for colitis. In his health situation surgery is and was the last resort. Not unlike a lot of people in that age range with the last stage of kidney function, getting him to wake up and removal of the ventilator were among many major concerns.
So far, so good. This morning there was no change but I just visited him after lunch today (Thursday) and he was sitting up and able to speak. His speech is hoarse and not very legible, but a big improvement from earlier.
I will keep you updated.
