And lastly, you talked about brain training.

There's the classic story of someone retires or they stop working and

they're less engaged and the brain kind of goes to mush over time.

So in your view, what are the things, no matter what stage of life you're at, maybe you're not working, maybe you're retired, maybe you're not challenged, like what must you do on a daily basis to engage and train your brain?

So in terms of learning, would it apply to, say, listening to a podcast or watching a documentary where your brain, you know, maybe you're driving and you're listening to an engaging podcast where it's passive, but the brain is engaged.

You're actively listening and soaking information.

Would that qualify as brain training?

So I'm assuming reading a book would be better than listening to a book.

So you mentioned HRV earlier.

It feels like possibly a metric we should be paying attention to.

in terms of our brain health?

Yes.

And so for one who wants to track how they're doing here, HRV inching higher would indicate I'm doing a better job of managing my day-to-day stress and vice versa, HRV dipping lower, maybe have some more room for improvement.

So if someone's wearing a wearable, like a Whoop or an Aura, just does it overnight, and you wake up and you see your HRV, yeah.

Intelligence.

You outline over 30 forms of intelligence.

Why do you think so many successful, bright, smart adults don't think they're smart?

Can you spend a moment, why is hand-eye, you know, I think of all the great hand-eye activities one can participate in as they get older.

You know, ping pong, you know, pickle, the list goes on.

Why is hand-eye just so great for the brain?
