Suffering from the effects of over-reading (as per usual), I was just thinking about the commonalities between some notable self-defense moments in fiction and in real life. These included (but were not limited to): the sword duel between Oscar and the Eater of Souls in Heinlein's "Glory Road", the boar hunt in "Thais of Athens", the two big battles in "IT", Richard Cypher's "dancing with the dead" in "Wizard's first rule". What all these things have in common is - the protagonists ultimately emerged successful from them all, but not because they knew what they were doing. All these fights were basically forced on them and, somehow, even while bungling it, they managed to live through it and inflict damage on their opponents. The "Glory Road" duel in particular is notable in the description of that decisive maneuver Oscar ends up using. He admits to only remembering the maneuver, not even seriously thinking about using it, because it is extremely dangerous unless executed perfectly. And then, at just the right moment, his wrist takes over and he corkscrews the other guy.
Yes, of course, it's all a fantasy, and yet... Had we nod had situations where we did something, having not a clue how we did it, to escape a dangerous situation? I think that's the point where you can tap yourself on the shoulder and say "yup, I am getting kind of good at this", because your mind and your muscles have reached the level of conditioning you are not even aware of. At the crucial moment, some weird little autopilot takes over and does what he does just right.
I wish I could ask Captain "Sully" Sullenberger what it was like when he landed the plane on the Hudson. Considering the pilots train for stuff like that but don't really get to execute this particular operation on a regular basis, I wonder what level of conditioning he was at when he pulled it off.
