From reading books about cognitive learning, you can take the example of a toddler learning about dirt. The parent can show the kid dirt, talk about dirt, point at dirt, but until the kid eats dirt it will not know what dirt is and what to do or not do with it. The same thing with emergencies, IMHO. Unless you train for it in some way, an emergency will set your brain into confusion and overload. You can learn from it that way.
One example, I recently wrote that I was a calm sailor-dude that kept a smaller Bruce anchor on a 1/2" line (with no chain) at my feet near the helm and when my motor stopped recently I reached down and threw it out to stop my boat from hitting a oncoming big cruiser in the ICW. What I conveniently left out was that on a previous motor-problem occasion last year I let the wind drive my boat and me and screaming Admiral 150 feet into marsh grass in a strong wind. It took hours to kedge myself out of that mess that I could have avoided with my present always-handy anchor.
So for those future and inevitable mishaps that we all will have, consider it "eating dirt."
