Miscellaneous

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.
