I hope it helps me keep my mind sharp.
I think it does. At least, I reckon it slows the decay.
I always love a book series that allows me to get immeresred in a world. It doesn't happen too often though.
I wonder if fantasy or the reality type stories are more immersive?
Fantasy for me.
I think so too. Maybe it is because it requires more investment to build it, whereas reality doesn't take as much work as things are already held in the head from experience.
