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

And that's something that I'm really curious about how that will change as we get older.

And some of our research suggests that as we get older, we're more selective about what we focus on.

And I think that can be beneficial.

So maybe you don't waste as much time on trying to learn everything, but you're more focused on the things you want to learn about.

Yeah, it's a great question.

I think it's a little bit of both, and you want to have that sort of balance.

So if you play piano, my father in his 80s and 90s still plays piano.

I don't think he's learning new pieces, but he's strengthening the pieces he knows, and that keeps him sharp.

On the other hand, being exposed to new things, if you're traveling, if you're talking to different people, that can be really important for things like even neurogenesis.

You want to...

develop new brain cells, which we know doesn't just stop as we, you know, reach a certain age.

So it's probably a bit of both.

And people ask me, you know, what's the best thing to keep my brain sharp?

Is it crossword puzzles?

And that's interesting because I think as we get older, our actual verbal knowledge is maintained, if not improved.

So in a way you're strengthening a strength.

And I think that can be beneficial, but probably the other things to do are do new things.

Go outside and appreciate the birds or talk to someone who has a different perspective, or you go to a different restaurant even.

All of these things I find as I get older, I have a lot of routines.

But it's when I start to violate these routines, take a different way to work or try something different at a restaurant, I can almost feel like, wow, that was a different experience today.
