Glad you're still alive mate.
When out in the middle of nowhere, a lot of stuff can get you, even if some things arent that apparent. (like dehydration, i once had a group to guide with a pregnant woman, it was a burning hot day and we told the group to take plenty of water. However, they took a small AA drink bottle per person in the group, which wasnt nearly enough for even 1 hour, and they had to walk all day and do intensive activities. It wouldnt surprise me if she could have lost that baby)
I havent experienced anything that serious myself, but once i went rock-climbing in France for examinations.
We had to show we could save people from a stone cliff, and i was playing a victim.
This one guy had to 'rescue' me, but he didnt quite know what to do and he was a millisecond away from cutting my last safety line, which would mean i'd fall to my death.
The examinator was just barely in time to notice it and calling him out to his error.
In the end though, he did let me hang there long enough for my legs to go completely numb. Once i finally got on the ground, they were like spaghetti and i couldnt even stand for 5 minutes.
