I like books. I have a ton of them in all different genres.
I have both fiction and non-fiction. I have how-to manuals, biographies, classic literature and futuristic Science Fiction as well as textbooks and several books on string theory, including one really huge, thick book.
Of course, that one is mostly obsolete now.
The thing is, books allow you to visit places you could never go on your own.
I believe the picture in today’s jigsaw puzzle represents that quite well.
Enjoy!
