It’s been proven that when you read a book, your brain power increases. This is due to a few different reasons.

There is a romantic kind of relationship that we have with books too. Even the front cover can invoke a feeling based on a special memory. Reading a paperback can bring you back down to Earth, ground you, and give you the brain power to do deep work.
