Well....it's not good at all.
My wife stopped in to see him on her way home from work, and she was able to talk to the two neurologists that are monitoring his condition.
They were very frank with her, and said they doubted if he'd ever regain consciousness. When she asked them what would happen if they took him off the ventilator, they told her that he'd stop breathing on his own after "a short time".
They didn't quantify how long a "short time" would be, but she got the distinct impression it would be less than 24 hours.
I'm greatly saddened by this..............
