Why smell jumps the queue when it comes to memories

Smells hardwire deep into the brain, writes Henna Cundill, as she explores why they jump-start such vivid memories.

When I was a 22-year-old undergraduate my mother died quite suddenly. I can't remember the name of the undertakers we used, nor the chaplain who took her funeral. I can no longer visualise what any of their faces looked like. I know I visited the chaplain’s house to plan the funeral, but I can't remember exactly where that house was. What sticks is that the day of the funeral was a sultry summer's day, and both the chaplain and the undertakers smelt of perspiration. To this day there are moments where I catch that same whiff of man-sweat in some other location, and for a fleeting second, I am a bewildered 22-year-old once more. 

Here is another memory. I attended a tiny, rural Church of England primary school in the middle of England. At the end of each school year, all of us donned our little Wellington boots, which smelt faintly of slurry (since this was dairy-farming country) and sweaty feet. Then we lined up in a crocodile and trudged through the bluebell-wood (damp leaves) and skirted the edge of fields (silage, which stings the nose) covering the mile or so between our school building and the village church. 

We would enter the church grounds through the back field, hurrying through an eerily muffled graveyard with tombstones towering far above our heads and the grass disturbingly lumpy beneath our little feet. To the chidings of “Quickly!” and “Quietly!” we children scurried down a gravel path, away from this unsettling place of death, to reach the cool sanctuary of a little church, and the comforting smells (for me, at least) of damp stone and dusty hymnbooks. 

Others may not have the same associations, but for me the smell of dust and damp stone will always cry “safety!” and the reassurance that “there are no ghosts in here!” in contrast to that troubling graveyard. From death to life. Yet, at the same time, getting stuck with my nose close to some man’s whiffy armpit on the Tube will forever insinuate that I am just a child pretending to be a grown-up, out of my depth, overwhelmed with one thousand decisions to make (“What flowers do you want for her coffin?”) and no-one to advise. In the midst of life, death again.  

On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances.

Of course, I am not 22 years old and lost anymore, no matter what that man’s armpit tries to tell me. My rational mind knows better, but my rational mind doesn’t get a say – or doesn’t get the first say anyway. This is because smell is the only one of our senses that bypasses the thalamus (the brain’s ‘filtering gate’ that decides which part of the brain needs to respond to sensory input) and goes straight to the limbic system, where emotional memory is stored.  

Sometimes it is very obvious that this is taking place, such as in the examples given above. On reflection I will know that my emotions are being manipulated by my nose, in ways which are more or less than helpful depending on the circumstances. But it can happen in more subtle ways too. Supermarkets infamously pump out smells to influence our buying choices, and we’re trying to sell our house right now, so we’ve been brewing a whole lot more coffee than we ever usually would.   

Intriguingly, scientists don’t really know why the human sense of smell jumps the queue when it comes to cognitive processing. There are biological theories, such as that the smell of predator could wake up our ancestors while they were sleeping and/or could allow them to follow a scent trail quickly when fleeing danger or seeking food. There are social theories too, such as that we don’t have a lot of good words to describe smells, so the brain just doesn’t bother trying to analyse them. Whatever the truth of the matter, the reality is that (whether we like it or not) our noses are an emotional trip-hazard.  

When I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. 

I can’t help wondering what this tells me about my religious practice. Do I go to church because I have made a cognitive decision to worship God each Sunday? Or do I go to church because I am following my nose, getting away from a world full of armpits and responsibilities to a place where I am a seven-year-old girl, all gingham dress and wellies, feeling safe. If so, does it matter?    

Truth is, my mind can give me a dozen reasons not to go to church every single week. In fact, two dozen reasons. More. It has always been a busy week; I’m always behind on work. The house always needs a sort out and the car is never washed. But because certain congregation members are normally counting on me for certain things, and because I’m still pretending to be a grown up, I typically drag myself out the door, and off to church I go.  

And week on week, without fail, when I walk through those great oak doors there is a moment, a glitch in the matrix, when the unmistakable smell of church hits my nose. Dust, damp… a little hint of mouse. My body registers this before my mind; my shoulders drop a little of their tension. Even if it’s just for a fleeting moment, I start to feel that I know for sure what is absolutely real in my life and what is just pretend.  

Is this knowledge irrational – since it doesn’t come from the cognitive part of my mind? Or is there a God who knows that the cognitive part of my mind sometimes tells me all sorts of untrue and unhelpful things. Is there a God who is choosing to reach out to me in more subtle, more ancient ways?  

I can only wonder if I have been following my nose all this time, without even noticing. Drawn along by an ancient scent trail that leads me time and time again…this way…and that way…until I reach a place where there is safety, and bread.

How a card game, going off-grid, and a great teacher, shaped Bill Gates

A new biography explores the man who shaped the digital decades

Krish is a social entrepreneur partnering across civil society, faith communities, government and philanthropy. He founded The Sanctuary Foundation.

It is hard to find Bill Gates the man behind Bill Gates the tech billionaire. The founder of Microsoft is consistently portrayed in the media solely through the lens of wealth, influence and innovation, and with good reason. For decades he has ranked one of the richest men in the world with a net worth of around $113 billion, and his most recent operating system running on over 400 million devices around the world.  

But in the first instalment of his planned three-volume biography Bill Gates reveals something of his personal story - of the rituals, coincidences and relationships that have shaped the man who, like it or not, is shaping all our lives

As someone who grew up riding the wave of the technological revolution of the 1970s, 80s and 90s, I found Bill Gates’ deeply personal portrait particularly fascinating. But the themes of his book resonate even wider - the way he talks about relationship and risk, inclusion and inspiration, memory and morals, are poignant however much time you spend on your computer and however much money you have in your pocket.  

Hearts with Grandma shaped Gates’ childhood 

The powerful influence of Gates’ family, particularly his grandmother, is unmistakable. The biography opens and closes with the woman who called him “Trey,” recognizing his place as the third William Henry Gates in the family. Their close bond developed over the card table, where Gates sat in awe of her mental sharpness. Even into old age she regularly beat him at her favourite game, Hearts. It’s likely not a coincidence that this game made it into Microsoft’s early operating systems: Gates’ way of sharing something of his grandmother with the world. But Hearts was more than a card game. It symbolises the space Gates was offered to learn strategy, logic and focus. It was a levelling of the playing field across generations and an opportunity to discover and refine his sense of identity, competition and connection.  

I found myself reflecting on my own childhood, and those long dark evenings playing Carrom and Rummikub with my mum, at least until I was seduced by Pacman and Elite on my microcomputer. Then I thought about how that played out with my own children who I once taught to play Uno and Connect 4 and who have subsequently introduced me to the challenges of Catan, Carcassonne, Codenames, Ganz Schon Clever, and so on. Card and table games have had their own mini-revolution since the days of Hearts and Patience: they continue to be the school where early learners develop strategy, connection, and identity.  

Off-grid and online life shaped Gates’ young adult life  

Gates’ childhood, as portrayed in his biography, feels like it belongs to a completely different era. It makes me feel uncomfortable as he describes the way he used to disappear as a teenager on a nine-day hike through the Cascade Mountains in Washington State with friends—no mobile phones, no contact with home. In one remarkable story, his parents managed to reach him by phoning a random stranger in a town along his route. That stranger successfully relayed the message that his family’s planned rendezvous had changed. It’s an image from a different world, one of off-grid trust, risk, and adventure—far from the always-on, hyper-connected digital culture Gates would go on to help create. How ironic that the skills Gates needed to become one of the central architects of digital transformation were formed in the middle of nowhere. The infrastructure of today’s information age—its fluidity, reach, and depth—was birthed in mountain walks, wild camping and lake swimming. 

The image of a young Bill Gates forging resilience and perspective far from the digital world is both nostalgic and instructive. Perhaps the next great innovators won’t emerge from the data diet or coding camps but from tents under the stars and homes where screens are conspicuously absent.  

Gates’ neurodiversity is his superpower 

One of the most important influences that emerges during Gates’ school education was Mrs Blanche Caffiere, the school librarian at View Ridge Elementary in Seattle. She not only managed the library but also invited young Gates to work as her assistant—a role that empowered him, nurtured his curiosity, and profoundly shaped his sense of belonging at school. Socially awkward but intellectually gifted, Gates was given a position of responsibility, and that act of trust and inclusion gave structure to his experience of school as well as a place where he could flourish. It’s a powerful reminder of the transformative role teachers can play—especially those who go beyond the curriculum to draw out the unique gifts of each student.  

In the book’s epilogue, Gates reflects on his neurodiversity:  

“If I were growing up today, I probably would be diagnosed on the autism spectrum… During my childhood, the fact that some people’s brains process information differently from others wasn’t widely understood.” 

 His parents seemed to respond to his difference with patience and ingenuity. While they clearly struggled, they also invested in his education and in supporting his mental health. Instead of framing neurodiversity as a deficit, Gates’ family recognised it as a form of untapped potential. And, on reflection, Gates agrees. Seeing the world differently, he has said, is something he wouldn’t trade. 

These three themes come together in one story that really struck home to me. As a child Bill Gates attended church with his sister, and on one occasion this church issued a challenge: any young person who could memorize the entire Sermon on the Mount would earn a meal at the city’s iconic Space Needle in its lofty rotating restaurant. With his agile brain, his family relationships and his growing resilience Gates memorized the entire passage verbatim, passed the test, and earned his reward.  

Memorising 150 verses is no mean feat, but it wasn’t the end of the story. That challenge sparked a deeper interest, and Gates went on to read the entire Bible from cover to cover. He recognized that discovery as a vital part of his journey toward adulthood, forming part of the moral and intellectual foundation that would shape his later life. 

Gate’s story, as told in this first volume, isn’t just a biography of a tech mogul - it is a window into the formation of a complex human being. What emerges is not just a tale of one success, but a testament to the quiet, often overlooked forces that shape a life, a community, and a moral framework. The time spent with a grandmother, the vision of a school librarian, the stillness of a night spent under the stars, the power of a sacred text:  perhaps here is the true source of the man who is Bill Gates.
