I play video games sometimes. They’re silly brainy games – Brain Age (1 and 2) and Big Brain Academy. One of them asked me to contemplate fictional objects. “Imagine a cat. Imagine a ladder. Now imagine a cat ladder. Was it furry?”
I guess it’s good for the brain to think about stuff like that. Imagine things that don’t exist (at least, not yet).
So is it good for the brain to create speculative fiction worlds? It seems like we’d have an advantage with all that.

That is funny. A cat ladder being furry. lol Or it could just be a ladder designed for cats, kind of like those cat homes that are carpeted with different levels. hmmmm
I’ve never heard of those games. Seems better than the mindless ones I used to play.
Sadly, the first thing I thought of when I heard ‘cat ladder’ was a smallish ladder made of cat bones. I guess that is why I write dark fiction.
