Your fall on the ice does not sound like any fun at all.
The important part is the in-your-face 'Not only can I theoretically die, it may be going on now' And the checking of soul-state that invokes.
I have to admit, I was annoyed, but never frightened. When I finally do get killed off, everyone can know that I am sure and certain in my salvation. ;)
Prayers from folks here on FR, and my home church, and others probably had an effect.
But my advice is get good doctors, and try to not do that. (stepping off into open space) And be ok with God.
