[Serious] "Doing Brain-ups", how do you exercise your brain?

[brewer]

I read journals every day and exercise the dogs. 

And type.

Let's see.

I am writing up a set of notes that starts with the axioms of set theory and develops the rest of mathematics. Even though I have a PhD in math, I have learned an immense amount from this project. It is currently at 780 pages.

I am learning Chinese (Mandarin). Currently working towards HKS3 status.

I am brushing up on French. I'd like to get to the place where I can read a simple novel in French.

After I get good in Chinese, I'll move to Portuguese.

Is that all?

No. Those are just the highlights.

Good, I didn't want to put you in the slacker category without checking.

Regular exercise, number puzzles and picture puzzles along with some reading here and there. 

I just like doing those things.

I write.

[no one]

I have the best brain, the biggest brain. Scientists call me all the time, they want to study my brain. They say they've never seen someone with such smartifing neurocepters. I have like the best and most amazing brain ever.

Spent fifteen minutes looking for the new glucose meter that was on my desk.

College killed my desire to read books in text. But audiobooks are awesome and a lot of them are free these days. I listen to audio books and podcasts while exercising, mowing the lawn, working on cars, working around the ranch, etc.

The best podcast app I've found is Podcast Addict. The interface is a little odd, but there are lifetimes worth of free podcases and audiobooks. The audio books are mostly public domain stuff- which isn't a bad thing. For newer audio books I use Audible like everybody else.

Sudoku online (hard, or expert level), Scrabble online, designing and building items out of wood, both with power tools and hand tools (as in wood carving).
