In the UK a man came around from a full coma after 19 years. I wish I could recall his name so as to provde a link.

He opened his eyes, and his first words were "pepsi" and "milk". His mother had cared for him daily. His memory was affected to the extent that he still thought he was 20 yrs old. He thought his daughter was his wife etc.

But he is alive and improving. Before I read his story I was in the euthanasia camp. Now I don't think I could make that decision.
