Yeah.

I'm going to send that to you.

We'll offline about that.

So the other thing I love...

about your approach and the book, it's this idea that modern convenience and over-optimization or retirement isn't exactly helping our cognitive health.

I think about the drive where I'm on a GPS versus the famous London cabbie study where being a cab driver in London is the most complicated

tens of thousands of streets to memorize.

These guys have like no shrinkage in their hippocampus.

I think about us, GPS everywhere.

I think about AI now.

I think about just not this idea you talk about this, like mistakes, challenges.

These are amazing for our cognitive health, but we are in a world where it's just too easy maybe.

So what do you recommend in terms of your protocol?

Okay, we're doing our resistance training at least twice a week.

We're doing our VO2 max cardio maybe once or twice a week.

What does this look like in terms of brain stimulation?

Is it a crossword?

Is it reading?

Is it a pocket?

What does that look like?
