I found tremendous amount of valuable information when I do intensive reading on a long form article, such as historical context, locations of cities and places, and other info that's only loosely related to the topic at home. Like I now know that spaced repetition systems that people uses for studying was a product of Soviet era research by a Polish academic. Though whether it's a warm morning or not is kinda useless to me.
