YOUR FIVE-MINUTE UPGRADE | NO. 009 | OCTOBER 9, 2026
Memory feels a little like a filing cabinet.
Something happens, your brain stores it, and years later you pull the same memory back out.
Except that's not really how it works.
Our memories can fade, pick up new details, lose old ones and even become more confident without necessarily becoming more accurate. Remembering isn't simply replaying the past. It's your brain reconstructing it.
This issue is about why memory is much less reliable than it feels, why forgetting isn't always a flaw and how the stories we remember can change over time.
THE BIG THREE
Three stories worth understanding. The context, minus the endless scrolling.
BUSINESS/FOOD
1. Pepsi is selling more snacks. So why is it making less money?
The gist: PepsiCo, the company behind Lay's, Doritos, Cheetos and Pepsi, reported a 5.6% increase in quarterly revenue on Thursday, beating Wall Street's expectations. But despite stronger sales, the company lowered its profit outlook.
Here's the interesting part: PepsiCo cut prices on some of its biggest snack brands by as much as 15% earlier this year. The strategy helped improve sales volumes in North America, but it also squeezed profits. Revenue at PepsiCo Foods North America was flat, while core operating profit fell 12%.
And snacks aren't the only challenge. PepsiCo's North American soft drink business has also been struggling to keep up with competitors.
Why it matters: Selling more doesn't always mean making more money.
PepsiCo is facing a dilemma familiar to businesses everywhere: lower prices can attract customers, but those extra sales aren't necessarily worth much if profit margins shrink.
It's also a reminder that even brands people have loved for decades can't assume customers will pay whatever they charge.

CULTURE/MONEY
2. Wealthy Gen Z collectors are outspending their elders on art
The gist: Forget the idea that serious art collecting is reserved for older billionaires.
A new Art Basel and UBS survey found that wealthy Gen Z collectors spent an average of approximately $347,000 on fine art in 2025, more than twice the average of any older generation surveyed.
It's a striking shift. Earlier editions of the survey had Gen X leading on spending, but younger collectors are now reporting some of the biggest purchases.
And despite growing up with social media, Gen Z collectors aren't necessarily showing off their acquisitions. Research and reporting suggest they're particularly selective about who gets to see their collections.
Why it matters: Art collecting may be changing hands faster than expected, but it's not necessarily changing in the ways you'd imagine.
Younger wealthy collectors still favour traditional art forms such as paintings and sculptures, and family influence remains important. About 40% of Gen Z respondents entered collecting through family connections.
One important caveat: the survey covered 3,100 high-net-worth collectors, with Gen Z representing only 9% of respondents. A handful of very large purchases can also push averages higher. This doesn't mean Gen Z spends the most on art overall.
WORLD/ECONOMY
3. Why one narrow shipping route matters to the whole world
The gist: A tanker was struck by multiple projectiles off Qatar's northern coast on Wednesday, with casualties reported, adding to concerns about security in the Persian Gulf. Responsibility for the attack has not been confirmed.
The incident comes amid an ongoing conflict involving the United States and Iran over the Strait of Hormuz, one of the world's most important energy shipping routes. Before the conflict, roughly 20% of the world's oil supply passed through the strait.
Shipping disruptions have become increasingly frequent. UK maritime authorities reported nine attacks in and around Hormuz during the first seven days of October alone.
With tensions rising, oil prices climbed above $100 a barrel on Thursday.
Why it matters: The price of oil isn't determined only by how much is produced. It also depends on whether that oil can reach its destination.
When shipping routes become dangerous or unreliable, the effects can ripple through energy markets and eventually influence transportation, manufacturing and consumer prices.
It's a reminder that a narrow stretch of water thousands of kilometres away can have an enormous influence on the global economy.

WORD ON THE STREET
Confabulate kun-FAB-yuh-layt | verb
Definition: To unintentionally create or fill in details in a memory that aren't accurate.
In a sentence: He wasn't lying about what happened. His brain may have confabulated some of the missing details.
Why it's worth knowing: We tend to think there are two options: you remember something correctly or you're making it up. Confabulation describes something more interesting: a person can sincerely remember something that didn't happen exactly as they believe it did.
THE BOOKSHELF
The Seven Sins of Memory by Daniel L. Schacter
Why forgetting things doesn't necessarily mean your memory is broken.
The big idea: Memory makes mistakes, but those mistakes can tell us something important about how the mind works.
Psychologist Daniel Schacter identifies seven common ways memory fails us, from forgetting where we put our keys to remembering something that never happened quite the way we think it did.
But his bigger point is that these aren't necessarily signs of a badly designed system. Some are consequences of the same mental abilities that help us recognize patterns, make connections and imagine the future.
What to take away: Your brain isn't designed to preserve a perfect recording of your life. Memory helps you make sense of experience, and sometimes accuracy gets lost in the process.
Try it: Think about a memory you've retold dozens of times. How much of what you remember comes from the original experience, and how much might come from telling the story?
THE POWER MOVE
Give people a memory they can keep
The next time you take a great candid photo of someone, send it to them.
Not just the group photo where everyone is looking at the camera. The one where they're laughing at dinner, concentrating on something they love or having a moment they didn't realize anyone noticed.
We're usually pretty good at documenting our own lives. We're less likely to have photos of ourselves genuinely enjoying them.
And because you were behind the camera, you might have captured a moment they wouldn't otherwise have.
Send it with a little context: “This was right after you told us that story. Still laughing.”
Sometimes the nicest thing you can give someone is a memory they didn't know they had.
THE PROMPT EDIT
Turn “I know I read this somewhere” into something useful
You read an interesting article. Three weeks later you remember approximately one sentence and absolutely nothing about where you found it.
Instead of asking AI to summarize something you haven't read, use it after you've read something to make the idea easier to retrieve later.
COPY AND PASTE:
I just learned the following:
[paste your notes, article excerpt or idea]
Help me remember the core idea without oversimplifying it.
Give me:
1. the idea in one sentence,
2. one memorable analogy,
3. one real-world example,
4. one question I can use to test whether I still remember the idea a week from now.
5. three keywords I could search later if I forget where I learned it.
Don't add facts that aren't supported by what I've provided.
Try it with: an article, podcast notes, something you learned at work, a book chapter or one of the Big Three.
THE RABBIT HOLE
One thing you didn’t know you wanted to know.
Remembering something can change it
We tend to imagine remembering as opening a saved file.
But memory research suggests retrieval is more dynamic than that.
When certain established memories are reactivated, they can temporarily become susceptible to modification before stabilizing again, a process researchers call reconsolidation.
Here's where it gets interesting. Remembering something correctly can actually make that memory easier to access next time. But if you recall it incorrectly, or pick up new details along the way, those details can sometimes become part of what you remember.
So the safest version isn't the internet-friendly claim that “every time you remember something, you rewrite it.” The science is more nuanced.
But it does mean memory isn't simply an untouched recording sitting somewhere in your brain.
Remembering is part of what keeps a memory alive, and sometimes part of what changes it.
