From what I understand, there is nothing overly to be worried about him, just he is getting old. The black out is possibly due to any matter of things – low blood sugar levels, his bad cold he has and his medication. He was moved to Greenslopes yesterday to be monitored for 24hrs and then decide what to do from there. He is now going to stay at Greenslopes for a couple of more days so they can keep an eye on him.
"The professor" is quite interested in his case as he has had no damage caused from his black-out, he didn’t fall out of the chair during his sleep(which is so lucky, since his skin is so frail). Again from what I understand, a pacemaker may be the go soon.
Thanks for your support.
