It’s always nice to learn there are proven benefits to a beloved hobby, and given all reading does for us, it seems like this is a hobby very much worth cultivating.
Reading is reading, right? To an extent, yes. Reading of any kind requires you to make connections, but a book with chapters—as opposed to, say, a newspaper article—generally requires more memory and increased critical thinking. This kind of work creates new neural pathways between regions of your brain, and that can lead to quicker thinking. So, reading something short and simple won’t necessarily be as beneficial as something that requires a deeper, longer read.
