Huberman Lab · How to Improve Your Memory & Cognitive Function at Any Age | Dr. Alan Castel · 13 Jul 2026 podcast

But there's a social component you're doing with other people.

And even when I think like the Steve Jobs thing or even when I talk to older adults, they're like, I like this part of my work life when it was a challenge and we had to travel here and do that.

It was exciting.

They wouldn't say it was relaxing and it's not something they want to revisit.

And it's interesting if you ask people, what age would you want to go back to?

Not a lot of people will say 20 or 15.

It's usually kind of closer to midlife, which is interesting because maybe everything's kind of firing on all cylinders then.

Your cognition's still pretty good.

Your family's still around.

You know, you have your job.

You're reinforced by a lot of things.

But it's not going back to this age, you know, when you're like 20, 25.

any experiments that your laboratory is doing now that you can even just tell us about the design of the experiment if not the results yeah well we're we've done some work on curiosity and i think that's something that from a lifespan perspective is interesting we've been measuring different types of curiosity one is known as state curiosity and one is known as trait curiosity and trait curiosity is just in general are you a curious person do you you know kind of get into things and have trouble if you don't learn the answer

which I think a lot of people can have.

But as you get older, that tends to decline with age, which I thought was kind of perplexing, because I have a lot of curious people.

But we've found that levels of state curiosity, when I give you some interesting bit of information, but I don't give you the answer, if it's something you care about, that actually increases with age, your level of curiosity and learning.

We think this is interesting because it probably guides our memory.

As we get older, you know, we're going to remember the things we care about.

And if you're curious, especially so, and there's probably some neurochemical pathway that is still engaged, even though we know all sorts of things kind of decline with age.

So that's one.
