Hi readers! Shayla Love here, science journalist and longtime fan of Your Mileage May Vary. I’m honored to be subbing for Sigal Samuel while she’s out on parental leave. I’m diving into your questions as a way to help understand human nature and our choices through multiple lenses: philosophical, psychological, and beyond. Please send in any emotional, body/brain, sociological, perceptual, or other kind of life quandaries you might have.

I am a (gracefully?) aging mother of three and proud grandmother of four. I keep hearing about how my generation (okay, I am a boomer) is hoarding wealth and failing to pass it down. 

When I look at my lifestyle, I’m facing a fork in the road. Either I splurge on a lovely retirement, or I save so my kids and their kids can have an easier life. We’re all middle-class, so this is not a question of survival. The kids have college funds. Do I owe it to my descendants to scrimp as I age? Surely it’s not right for me to spend my savings on bucket-list vacations…How should I balance spending on myself and on the others that will come after me?

Dear Rainy Day Funder,

I’m so glad to hear you’re not in financial survival mode. But you are facing some economic constraints: You can’t splurge on a luxurious retirement while at the same time saving a substantial nest egg for your kids and grandkids. 

It sounds like this feeling of either-or is causing you some anguish. The instinctual response is, as you suggest, to hoard as much as possible for your progeny to use later on. But at the same time, that feels like it’s zero-summing your own experience in your golden years. 

So I’d like to introduce you to an economic thinker who has some advice that might surprise you. John Maynard Keynes, 19th-century British economist, would say: Don’t save your money!

Keynes wrote that when times are tough, people react by keeping their money close, and not spending it. But this sets in motion what he called the paradox of thrift. One person’s expenses are actually another person’s income, he pointed out; if everyone saved their money, no one would make money either, and a recession could drag on and on. In the end, people’s savings would, paradoxically, go down, even though they were scrimping. 

We can apply the paradox of thrift to your own family as a mini-economy. Inheritance has traditionally worked by setting aside large chunks of your assets to pass along to your children and grandchildren — which could be helpful when the day of windfall comes. But why wait? And would waiting actually stymie your family’s financial potential? 

In past generations, an inheritance like this often happened far earlier. I’m comforted that we are living longer (an average of a decade or more longer) than in the mid-20th century, but this sets up new issues, as you’re stuck in, with when and in what quantity to transfer any extra resources. 

Now, as people retire with decades of good life to enjoy ahead of them, they are often doing so at the very same time their adult children are the most financially stressed: They are trying to buy homes, they’re in the busiest middle part of their careers, and many have children of their own they’re raising and trying to save for. 

This doesn’t mean you have to give away all your money to your family so that they can spend it on the pleasures you have given up. Keynes wasn’t anti-savings so that money could be spent frivolously. He did believe that spending money was one of the best ways to give the greater economy a boost. Perhaps there are ways you could think about spending your money that stimulate your family’s internal economy, that also help you enjoy your retirement. 

For example, you could invest in a lakeside property to kick your feet up at — an asset that will appreciate in value over time and be sold at a profit, or be passed down through the generations to enjoy for many summers to come. Maybe you assist your children in buying a home — one with a comfortable guest suite. You could invest in a business your children want to start, and help them grow something that could accrue more wealth over time. Using your money these ways may even feel more like splurging than scrimping! Yet, it ideally would achieve both: a fun way to spend your hard-earned money now, and create more abundance for your family’s future. 

A hidden bonus of non-traditional inheritance moves like these is that they all involve spending more time together with your family and potentially even strengthening those relationships along the way. The Greek philosopher Aristotle wrote in The Nicomachean Ethics that there were three kinds of friends. Some are based on utility, and exist only because of what people can get from one another. Other friendships are based on pleasure, when you like doing things with someone. Finally, friendships of virtue persist because you stick by people who inspire you by their strong character. Simply setting aside your money is a relationship that leans utilitarian. Working on a shared meaningful project could help deepen your relationships with your kids and grandkids in those pleasurable and virtuous directions.   

Speaking of, I don’t think you need to be making these decisions alone. 

You used an interesting word in your question: Do you, as an individual, owe it to your family to set them up with a more comfortable financial future, at the expense of personal indulgences? A lot of the discussion around older generations’ money, and whether or how they should pass it on, avoids dealing with this sticky moral component. Why should parents give their kids money? 

I think there’s clarity to be found in thinking more closely about why we owe each other anything.  

There are few better thinkers to turn to than Confucius to consider our obligations to family. The fifth-century Chinese philosopher believed that we can’t understand ourselves only as individuals. You are nobody when you are alone; you only come alive as a mother, a daughter, or a sister. These relational roles each come with specific duties and ways of interacting. Successfully fulfilling these roles within the family has a bigger impact, according to Confucius. It’s what creates the foundations for a harmonious and functional society. For children in this web of relations, it’s critical to uphold filial piety, or the need to respect, honor, and care for parents as well as all of their other elders and ancestors. 

Filial piety has, over the years, been criticized for being too rigid, and setting overly high expectations for blind obedience and conformity in children. So I’ve been interested to see the concept of reciprocal filial piety emerge. In reciprocal filial piety, children have a genuine feeling of gratitude to their parents for raising them, and any obligation they feel is heartfelt — they want to return the favor and care for their parents too. 

As a half-Chinese person, I find it interesting that in family life in the West, filial piety is often reversed. There’s a lot of air time discussing what parents owe their children, and not so much the other way around.

For example, I noticed that you don’t mention how your family intends to care for you in the future, or what they might feel a sense of owing you. If you do take a Keynesian approach to your family and decide to spend your money in ways that could benefit everyone, it might be worth engaging in some Confucian-tinted conversations not only about what you owe everyone else, but what you all appreciate about each other.

You can reflect, together, on how your family is stronger because of all the ways you’ve chosen to look after one another, not only because of how much money is in the bank. 

Bonus: What I’m reading

• I think it’s worth having a copy of The Analects of Confucius lying around, which is full of nuggets of wisdom. One morsel I recently read was about how to best get along with others: “The gentleman harmonizes without being an echo. The petty man echoes and does not harmonize.” The lesson is that we don’t gain much by blindly following and copying what other people do. The most harmonious way to be in a society, or even a family, is to have interlocking roles that complement each other, like different pitches do in a choir. 
  
• I thought a lot about getting older when reading this piece on death doulas by Alexandra Schwartz in The New Yorker. It serves as a reminder that people outside of the immediate family can also help with life’s hardest transitions. 
  
• And, for something fun: I enjoyed this investigation by Natalie Wolchover in Quanta on why she (or anyone) is left-handed. She explores left-handed stigma and neuroscience, as well as a theory about humans using their right hands because they once were better to win fights with. 

A theme park next door would probably come with some trade-offs. Like, horrific screams whirring past your house, for example. 

Universal Studios Hollywood’s “Fast & Furious: Hollywood Drift” coaster—its first-ever outdoor roller coaster—has been in technical rehearsals since July, when a limited number of park guests were invited to test it. The ride hits 72 mph and features 360-degree rotating vehicles designed to simulate drifting. It sits on a hillside in the park’s upper lot, elevated above the Lakeside Golf Course, overlooking the residential streets of Toluca Lake below.

The neighbors noticed immediately. “When it’s running, it’s constant, and it sounds like bloody murder over there,” Toluca Lake resident Colby Jensen told KTLA. “It’s like a horror film going on. Constant screaming, yelling. Very intrusive.” Patrick Nazari described it to the LA Times with similar alarm: “You think something is happening. Like someone is getting murdered out there.” A third resident, Leonard R. Garner Jr., added: “I heard it, and I thought to myself, there are going to be problems with this.”

Universal Is Adding Sound Barriers After Complaints About Its New ‘Fast & Furious’ Coaster

The ride’s location compounds the issue. An outdoor coaster at 72 mph on an open hillside, with no natural buffer between the track and the residential neighborhood below, sends rider screams across the golf course and into homes with the doors shut.

Universal had tried to get ahead of this. Inside the Magic reported that sound-shield panels were incorporated around portions of the coaster in February, months before riders ever boarded. The park also promoted “sound reduction technology” as part of the ride’s design. Then the actual screaming started. LA City Councilmember Adrin Nazarian this week announced Universal would install two additional barriers, with construction expected to be complete by early September. Universal says the ride currently meets sound ordinance requirements and is adding more barriers in response to community feedback.

Universal’s statement walked a careful line, noting it welcomed community input, planned a meeting with HOA leadership, and would “continue to engage with our neighbors as the coaster remains in technical rehearsals ahead of its opening.” An official opening date has not been announced.

Universal’s first outdoor roller coaster doesn’t have an opening date yet. The neighbors, though, know exactly what it sounds like.

Svalbard sits about 620 miles from the North Pole and is one of the few places left on Earth where polar bears roam freely. Thousands of tourists visit every year to see them in their natural habitat, and the Golden Rule is—look, snap some pics, and move on. Not everyone gets that. 

Earlier this month, an unidentified boat operator sailing through a fjord in northeastern Svalbard spotted a bear resting on land and responded by blasting the ship’s foghorn. The bear woke up and moved. The governor of the territory’s office issued a fine of $5,255 under Section 30a of the Svalbard Environmental Act, which prohibits needlessly disturbing, attracting, or pursuing a polar bear. The operator agreed to pay.

This wasn’t the first time this has happened. In June 2024, two guides with a French shipping company were each fined around $2,100 after steering paying guests in rubber boats toward a polar bear and cub feeding on a whale carcass in northern Svalbard. That incident was at least somewhat understandable, however dumb and misguided. Someone wanting a closer look is a human impulse. Blasting a foghorn at a sleeping bear is just being an a**hole. 

Norway Fined a Boat Operator for Disturbing a Sleeping Polar Bear in Svalbard

The rules have gotten stricter because tourism has boomed. Svalbard saw 506 cruise ships carrying 67,000 passengers in 2024 alone, a number that has doubled in under 15 years. Protections that took effect in January 2025 now require vessels to stay at least 300 meters from bears in summer and 500 meters through June. Fines are just the starting point for violations. In serious cases, the penalty goes up to five years in prison.

The bears are doing better than the headlines around them suggest. Jon Aars, a senior scientist with the Norwegian Polar Institute, led a team that tracked the weight and size of nearly 800 bears in Svalbard between 1992 and 2019 and found them healthy and reproducing despite major sea ice loss. “I was quite surprised,” Aars told CBS News, “because we have lost so much sea ice since I started.” His data suggests the bears have adapted, hunting more efficiently as shrinking ice concentrates their prey. “Some of us would predict that they should be in trouble already,” he said.

They’ve outlasted unregulated hunting and a warming Arctic. A foghorn is a minor problem by comparison, but it’s still a d*ck move.

The tiny microbes in your gut play a big role in who you are, how healthy you are, and, apparently, according to new research published in Translational Psychiatry, whether or not you exhibit psychopathic tendencies.

Scientists have found a link between certain gut and oral bacteria and traits associated with psychopathy. Don’t start chugging Greek yogurt and gobbling barrels of kimchi to veer your microbes away from psychopathy, because there are some huge caveats to that eye-popping claim.

The study involved 200 healthy adults who completed a questionnaire measuring psychopathic traits. They also supplied blood, saliva, and fecal samples. The researchers found that people with higher levels of three types of bacteria tended to score higher for traits including callousness, impulsivity, manipulation, and antisocial behavior—all hallmarks of the common psychopath.

Those three bacteria were Allisonella, Prevotella, and Cloacibacillus evryensis. If you’re wondering if there’s a bacterium that shows the opposite association, that would be Treponema vincentii.

Your Gut Bacteria May Be Linked to Psychopathic Tendencies

Now here’s the big caveat: the study does not show that bacteria make people psychopaths. As is often the case with scientific research, especially some of the more sensationalistic headlines you read out there, this study found correlation and not causation. A link and not a firm, fully established cause and effect. For now, this is merely a finding that makes you go “hmm” as you stroke your beard.

There’s also the matter of this particular study not yet undergoing peer review, so please do not use it as a means of accusing your roommate of being a psychopath because he didn’t take his probiotic that morning.

All that said, it’s an interesting find since psychopathy has traditionally been studied almost exclusively through the brain, genetics, and behavior. Examining it through the gut is a burgeoning concept that different research teams may explore down the line. Researchers already know that certain brain regions can be involved in the development of psychopathy; knowing that doesn’t provide the full story of its development. Our gut microbiome could be a huge missing piece of the puzzle.

Exactly how it fits in needs much more study. Maybe it has something to do with inflammation, neurotransmitters, or how gut bacteria influence emotional processing. For now, the researchers only have theories.

The “protein in everything” trend is rapidly approaching its logically ludicrous endgame. Recently, I wrote about how scientists are using a “gene gun” to shoot pig DNA into produce to create protein-packed lettuce. Now comes word that a separate research team is using algae proteins to create protein-enriched ketchup.

We’re really well on our way to creating a burger that, on its own, helps people get all their protein macros for an entire day in just a few bites. What hath man wrought.

According to a new study published in ACS Food Science & Technology, researchers in Russia and New Zealand experimented with adding protein extracted from Chlorella vulgaris, a protein-rich microalgae, to homemade tomato ketchup.

Regular ketchup contains a pathetic 1.6 percent protein by weight. Researchers managed to push that number to 6.3 percent by adding algae protein. The fortified ketchup also contained more essential amino acids, minerals, and antioxidants. It’s ketchup so healthy you can practically rub it on your skin as a beauty cream.

The Protein-in-Everything Trend Has Reached Ketchup

But the researchers did find a limit to how much algae humans are willing to put up with in their ketchup. A taste panel of 15 people found that ketchup containing 1 to 3 percent algae still looked and tasted like traditional ketchup. Once things tipped over into the five percent range, that’s when the unmistakable flavor of algae started to pop up.

At 13 percent, the ketchup was darker, thicker, and the algae-ness of it was dominating the flavor profile, causing its popularity to plummet. Turns out, people are willing to tolerate a precise amount of pond scum in their ketchup as long as it means a little protein boost.

Researchers say that microalgae could be a sustainable protein source and say can be grown year-round using just a little land and freshwater. This would make it perfect for adding a sustainable, affordable bit of protein to nearly any food on grocery store shelves. At the rate that we’re turning junk foods into health foods, it won’t be long before your mayo is filled with creatine and your American cheese is loaded with HGH.

We’re all going to be shredded, and we’ll have our greasy, 1,500-calorie burgers to thank.

There’s a reason dogs are trusted as emotional companions. If it seems like they have a nearly supernatural ability to sense human emotion, it’s because they practically do. As researchers at the University of Vienna recently found, dogs are especially good at parsing the emotions we humans are expressing with our faces.

The study, published in iScience, used fMRI scans to watch what happened inside dogs’ brains while they looked at photographs of human faces showing happiness, sadness, anger and fear. One of the study’s limitations is also one of the reasons the researchers were able to complete it at all. It’s difficult to get humans to sit still for an MRI scan, let alone a dog. The researchers had to use a specific breed, border collies, because they were especially good at sitting still on command. Border collies are great at following social cues and love following human orders.

In the first experiment, researchers found that happy human faces activated areas including the dogs’ temporal cortex and caudate nucleus. In a follow-up experiment involving 12 dogs, researchers went further, finding distinct brain activity patterns when the animals viewed fearful, angry and sad faces.

Dogs Can Apparently Read Your Face, Even When You’re Trying to Hide It

The researchers found that the dogs could distinguish between several nuanced expressions of emotion, particularly negative ones. That doesn’t necessarily mean that dogs totally understand emotion. They don’t look at your sad face and know that you’re sad because of your recent breakup. They just know that you’re sad.

In the real world, they have more information to work with than a still image of a sad face. Dogs pick up on and respond to a variety of cues, including body language, vocal tics, and even a person’s smell can tip off their mood.

While the study primarily focused on collies, broadly speaking, the study does offer some direct evidence of something that dog owners have long suspected: our precious, angelic little pooches really do seem to know what we’re feeling.

They don’t know why you’re in a bad mood. But they know you’re in one, which is a lot more than some people can say about their human partners.

No matter how hard we try, remembering anything that happened to us before the age of, say, 3 or 4 years old feels impossible. Even memories before 7 years old feel hazy and fragmented.

Our brains just aren’t built to store specific memories from our first few years, something known as “infantile amnesia.”

And chances are, even the earliest memories we think we have might just be amalgamations of stories we’ve been told, images cribbed from old family snapshots and home videos, or scenes we’ve borrowed from movies or TV shows.

So does it really matter if it happened, if we can’t really remember it?

Yes, science says. Even if we don’t have a specific memory of what happened when we were babies, those experiences leave lasting impressions on us of being safe and being loved, which shapes how we form relationships later in life. But whether babies are able to encode and store permanent memories is still an open question.

Columbia University cognitive psychologist Tristan Yates put babies in MRI machines and showed them a series of images, and found that the babies tended to stare longer at an image they’d been shown before, suggesting that they remembered seeing the image the first time.

“We are showing that they’re able to form some memories,” Yates said. “The hippocampus is capable of forming specific memories over a few minutes, but now we need to start doing the research that can get us at longer durations, that can get at more complex memories.”

One theory for infantile amnesia is that an infant’s brain is prioritizing learning general skills, like how to walk or talk or eat, or learning to detect patterns like a bedtime routine, rather than storing specific memories that aren’t necessary for survival.

Noam Hassenfeld spoke with Yates and Dr. Dana Suskind, a professor of surgery and pediatrics at the University of Chicago, on the latest episode of Explain It to Me, Vox’s weekly call-in podcast.

Suskind studies early childhood development and the important role that parents and caregivers play, and she told Noam about how our early childhood experiences can shape us.

You started out as a cochlear implant surgeon and now you’re working on childhood development. How did that happen? What’s the connection there?

It actually makes a whole lot of sense. When I first started our pediatric cochlear implant program at the University of Chicago, I started implanting cute little kids who all look like they had the same potential to thrive after implant surgery, and found very quickly that I could implant two children who looked very much the same, who had parents who loved them equally, with the same technology, but they would have very different outcomes, with one of them really thriving after surgery in terms of language learning and trajectories, and others barely able to communicate. 

It was that experience and seeing these huge differences in outcomes after the same surgery that led me into this incredible world of childhood development and the importance of the early years and the importance of parents.

Humans come out with brains that are literally only one-third the size of adult brains. That’s very different than any other species. It’s why the puppy can start feeding itself pretty quickly and start walking, whereas the human infant is helpless. In those first three years of life, 85 percent of the physical brain is built during those periods of time. 

A million new neural connections happen every second. The environmental input, the input from parents and caregivers — every serve and return, every touch, every gaze — literally is helping shape and strengthen the neural connections that happen in our brain. 

The brain isn’t being just built for your child’s vocabulary development or their literacy ability. It’s building their social brain, their ability to relate to and connect to the rest of the world. The relationships and the expectations for relationships are built in those early years.

Tell me if this is maybe an oversimplification, but I’m a parent of a young son; he’s a little over 7 months old. And I feel like what I’m doing when I’m raising him is building the structure of his brain, or building the architecture, and all the other stuff, all the specific things, are going to fill in all the rooms of the big building that we’re constructing together. But he’s not going to start filling those in with specific ideas or specific memories until later on in his development. 

The analogy you make is exactly right. I think of building the physical brain — if you were thinking about it through a computer lens — as building the hardware, the firmware, the memory, the RAM. I think of K-12 as really important, but I think of those as software updates. But these early years are building that infrastructure.

“I want you to not strive for perfection, because the one thing that AI has shown us is that humans don’t grow from perfection and frictionless existence.”

At the end of the day, it’s your attachment with him, being the perfectly imperfect parent. I want you to not strive for perfection, because the one thing that AI has shown us is that humans don’t grow from perfection and frictionless existence. So feel okay every time you misstep, misunderstand and repair, because that is, for him, building the understanding of, “I can be loved by another human who missteps but is able to repair.” He is starting to understand how to expect to be treated. 

That’s why it’s almost like you’re building the relationship map for him that’s going to allow him in the future to have expectations of how he’s going to be treated and loved by an imperfect human: building that strong bond, showering him with rich language, that back and forth, looking at him as a conversational partner from day one. 

It’s interesting you brought up AI and friction. What do you think this idea of a more frictionless existence is going to start meaning for kids?

I had a book that just came out on this called Human Raised, and that’s a lot of the argument of the book. Children learn from imperfect parenting through friction, through the productive struggle. And we’re seeing that friction that we’ve always looked at as a bug in the system — like, “Oh my gosh, I wish this was a more frictionless existence with the other humans in our world” — what we’re finding is that it is key for relationships development, learning to have relationships, and actually even learning. 

That’s why, writing an essay with an LLM — you don’t remember it at the end of the day. There’s something about what happens in the brain that we’ve discounted on the friction side of things. So I actually think in some ways friction should be the word of the year, and we need to embrace it a little bit more. We don’t need to friction-max, but we do need to see the power of the friction.

It sounds like even if my son is going to forget all of this, maybe on a deep level it’ll stick with him. But should I still have a nice big 1-year-old birthday party?

Heck yes. Because you’re doing it partially for you — and the grandparents, let’s be clear. Those are wonderful moments that they do remember at some level. My son, who’s now 20-something in medical school, was obsessed with Thomas the choo-choo train. I still have the box of the Thomas the choo-choo train. 

He may not remember exactly that birthday party and the cake that I worked very hard on, but it’s even fun to talk about it now in his twenties. So yes, do enjoy every moment. Don’t get obsessed, like everything has to be perfect, but those are memories for everyone.
