Use it or lose it. Applies to all information. Find a way of using it otherwise you lose it.
Tell someone what you learned, have it in a form of easy retrieval, like mind-mapping or sketchnoting. Something that makes it possible to review the information, use spaced repetition.
Yes I can remember, the significant activations. When I've used the information. If I didn't it has no major importance in my life. If it does, I will use it to remember it. Making retrievable hand drawn notes is my preferred method.
