five points for 20 minutes of programming, no AI, maybe do three points for 30 minutes of being immersed in a craft-based hobby, and so on, right?

So we can imagine a system like that.

So if we use the sample system I just talked about, here is an example of a collection of activities that would get you to 30 points in a week.

Reading 100 pages of a moderately complex book, which gets you 10 points, taking a 30, I think I'm thinking here, two different 30-minute thinking walks,

I have to have six points.

An hour total of deliberate practice on guitar, eight points.

And an hour spent working in the garden, six points.

I might not have got that exactly right, but something like that adds up to something like 30 points on my scale, right?

So that's like a non-trivial amount of cognitive fitness work.

So you would have to actually put aside some time and have some intention to actually get there.

Now, I don't have like a final definitive point system to recommend yet, right?

And I think that's something I might actually work on for an upcoming episode.

But for now, you might consider doing something like this on your own.

Writing out a system, a point system for various cognitive fitness activities and setting a 30-point-a-week goal, keeping track of it.

And this will push you to do more stuff with your brain than you otherwise might have.

All right, so that's our second tier.

That's sort of like serious intensity of cognitive fitness activity.

As we continue this thought of experiment of taking seriously what will happen if cognitive fitness becomes $100 billion industry, let's go to our third tier, which I'm going to call insane mode intensity.

And what I want to do here is look to the future.

So the first two tiers are things you can do.
