[Here](https://www.richroll.com/podcast/andrew-huberman-533/) is one of many podcasts with Dr. Andrew Huberman. He’s a neuroscientist who talks about neuroplasticity. Basically it’s expanding your brain’s ability to learn new things. I think he mentions how this is linked to reducing late age cognitive disorders.
So basically you’re flexing your brain by being creative or learning a new instrument, etc.
