A similar story;
A couple of years ago a dear friend's son wrecked his motorcycle in the desert. He was comotose, and had to be airlifted to a nearby hospital. He had brain swelling, and had a door of bone removed from his skull. The door was stored in his abdomen to stay alive. All was restored after he regained conciousness several weeks later. With a lot of terapy, he returned to normal, (except for a slightly mis-shapen head), and even allowed to remain in the Marine Corps.
As you might have guessed, the hospital staff was one of the best in the area. The family however is devout Roman catholic, and are still convinced that the young man's recovery was due to prayer.
