I once almost fell off of a cliff to my death - my camera in my pocket first fell out, as I was hanging there on the rock ledge by one hand, legs in the air - I felt it slip out, then I heard it hit the rocks below rather too long a pause later. (It was in its case, so it actually survived). Later someone came by and helped me up. I was done climbing for the day.

Then silly me, I'm crawling through a cave a month later and I climb up this cliff inside the cave, and when I get to the top, I'm having a conversation with someone else there and for some reason, without thinking, I take a step back - and find my foot connecting with air. Fortunately for me, there was a V-shaped impression, and that is what I stepped into, so my thigh caught on the "V" and stopped me from falling backwards onto solid, jagged rock 15 feet below. (And then good luck getting help deep in the bowels of a cave we spent an hour crawling and climbing through to get that far.)
