I'm stunned too. One minute he was one of the brightest minds out there, the next he suffers major head trauma, is decapacitated for months, and noone knows if he will ever recover fully since he has short term memory problems currently. It is absolutely terrifying!
I can't even imagine what his mom and sister have been going through. That phone call is what nightmares are made of. Their lives have been on hold these past few months in order to be by his side.
It looks like he is recovering miraculously well given the extent of his injuries. Here's hoping he keeps it up. He will never be the same but here's hoping he comes pretty darn close.
