Its a step forward but a long road to some kind of recovery if at all.
There is a 16 year old kid I know who was in a coma for 6 months after hitting his head. He is a complete petrolhead so I usually take him for a drive every Sunday morning. He can't walk and struggles to speak. Based on this, I fear that we will never see the old Michael again.
Anyhow, great to hear some positive news.
