Remember how lucky you are!

No explanation for firefighter's recovery: "The latest case involves firefighter Donald Herbert, 43, who has lived at a nursing home in suburban Buffalo, for more than seven years.
In December 1995, the roof of a burning home collapsed on him. He went without oxygen for several minutes before he was rescued, and he ended up blind with little, if any, memory. He was largely mute and showed little awareness of his surroundings.
But last Saturday, he suddenly asked for his wife, Linda. And over the next 14 hours, until he fell asleep early Sunday morning, he chatted with her, his four sons and other family and friends, catching up on what he'd missed.
'How long have I been away?' Herbert had asked.
'We told him almost 10 years,' said his uncle, Simon Manka. 'He thought it was only three months.'
...
And Tennessee police officer Gary Dockery, left paralyzed and mute after a 1988 shooting, began speaking to his family one day in 1996, telling jokes and recounting annual winter camping trips. But after 18 hours, he never repeated the unbridled conversation of that day, though he remained more alert than he had been. He died the following year of a blood clot on his lung."
