He's now out of hospital...which is a plus.
However that only means he's out of the coma...and can breathe unassisted.
There weren't many who thought he'd wake from the coma, even some medical experts, so this is a step in the right direction for him.
It is, as you allude to, only the beginning of his recovery process, so let's hope it is not too prolonged or difficult for him.
I recall endless months of physiotherapy after my accident to regain muscle tone and balance after what seemed like an eternity laid up in bed [almost 3 years]... and when I had regained enough strength, having to learn to walk all over again. Schumi has all that ahead of him, but he is a fighter, and if he's half as determined as I was he'll be back on his feet sooner rather than later.
All the best Michael.
