This is so sad. But maybe there is some hope. I didn't think Bozon would make it, I didn't think Schumi would wake up from his coma but I was wrong. Hoping for a miracle...
I'm a nurse and have worked with patients with severe head trauma, both in a "medical" setting and in a "mental health" setting.
He woke up, and might or might not be able to give an interview one day, but he most certainly will be a changed man forever. Wouldn't want to be in his families' shoes right now.
There are some varied and very tough consequences to such head traumas, symptoms that will affect him (pains, headaches, dizziness, etc) AND changes that will affect those around him (personality, behavior, losses in mental abilities). I've seen patients VERY happy to see their family members only to punch one of them minutes later for no reason. He has lost the ability to stop his pulsions, and for some reason felt like punching then and there.
EDIT I guess what I'm trying to say is that sometimes "a miracle" isn't so great after a while. I do wish all the best to him though, hope he comes back healthy and lives a good life.
