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.

Tom Cruise’s Ethan Hunt offers a blueprint for life

The latest in the Mission:Impossible franchise dares to ask some surprisingly existential questions

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

Tom Cruise runs.
What happens we he stops running?

When it comes to action movies, most of us aren’t looking for philosophical musings as much as a dose of adrenaline-fuelled escapist entertainment. Few franchises understand this better than  Mission: Impossible, which has consistently delivered on that front—train wrecks, car chases, gun battles, bomb blasts, submarine fights, knife fights, fist fights, dog fights, and, of course, running. Lots of running. 

The latest blockbuster in the franchise, Mission: Impossible – The Final Reckoning — which Tom Cruise has suggested may be his last outing as Ethan Hunt — is no exception. But alongside its brilliantly choreographed action scenes, the film also dares to ask some surprisingly existential questions. 

Who wants to live forever? 

Tom Cruise has achieved legendary status not just for his acting, but for his relentless dedication to performing the most technically demanding stunts in cinema history. Over the years, he’s scaled the Burj Khalifa, clung to the side of a plane during take-off, parachuted from 25,000 feet, flown helicopters through perilous terrain, and held his breath underwater for more than six minutes—without a stunt double in sight. 

Now 62, Cruise would be forgiven for taking it easier. Instead, after performing in what one director has called the most ambitious stunt in cinematic history: launching a motorcycle off a cliff, a mid-air dismount, followed by a parachute drop in the previous movie, Cruise has upped the ante again by engaging in an aerial battle atop a biplane flying at 10,000 feet. This involved climbing onto the wing of a moving aircraft travelling at 145 mph enduring hurricane-force winds, while the pilot performed manoeuvres designed to dislodge him. 

Cruise has become something of a cultural symbol of immortality. His character, Ethan Hunt, continually evades death, rarely stopping to mourn the losses of others—even those closest to him. But this film feels different. It asks how long someone—real or fictional—can continue to outrun death. 

Watching Hunt - and Cruise - cheat death time and again may be entertaining, but it also taps into something deeper. A recent COMRES survey revealed that the top four human fears are all death-related: dying in pain (83 per cent), dying alone (67 per cent), being told they’re dying (62 per cent), and dying in hospital (59 per cent). Final Reckoning doesn't just distract us from these fears—it subtly forces us to confront them. No matter how fast, fit, or famous we are, none of us gets out alive. 

What is life really about? 

Because the line between Ethan Hunt and Tom Cruise is now so thin, Dead Reckoning plays almost like a eulogy to both. The film opens with a message of thanks from the President of the United States: 

“Good evening, Ethan. This is your President. Since you won't reply to anyone else, I thought I'd reach out directly. First, I want to thank you for a lifetime of devoted and unrelenting service… Every risk you've taken, every comrade you've lost, every personal sacrifice you’ve made, has brought this world another sunrise.” 

The sentiment feels a little self-indulgent. The camera rarely leaves Cruise, and nearly everything and everyone else feels like a garnish to his character. He gets the best lines, the best cars, the best love interests, the best scenes. At times, Dead Reckoning feels a little like Mamma Mia! — a loose thread of a plot connecting a series of spectacular set-pieces rather than musical numbers. 

Still, as the franchise nears its end, it’s bittersweet to say goodbye to a character who’s become part of global popular culture. And it prompts a deeper question: If we can’t look back on our lives and say we gave the world another sunrise, what does make a life well-lived—for those of us who don’t defuse nuclear bombs before breakfast? What have we personally sacrificed for the greater good?  

Who Is expendable? 

With a body count hovering around 500, the Mission:Impossible series has never shied away from collateral damage. Ethan Hunt has always been portrayed as someone willing to expense the few to save the many. 

But The Final Reckoning confronts that idea. It reintroduces William Donloe, a minor character from the original 1996 film, who was the CIA analyst that got reassigned to a remote outpost in the Bering Sea after Hunt famously infiltrated his high-security vault - in that iconic scene where Cruise is suspended from the ceiling, inches above a pressure-sensitive floor, and drops his commando knife, point-first, into the desk. Now, decades later, Hunt seeks him out to apologise. 

Surprisingly, Donloe responds with grace. He says the reassignment was the best thing that ever happened to him: it led him to meet the love of his life. Though he had lost everything in a house fire caused by Hunt’s team, he had managed to salvage the commando knife from the original vault heist and gives it back to Hunt as a token of his appreciation. 

This could have been a moment of genuine reflection for Hunt—a chance to reckon with the unintended consequences of his actions. Instead, it serves to reinforce the idea that even Hunt’s mistakes are somehow for the best. Hunt is presented as almost messianic—an infallible saviour whose instincts are always right. 

But this portrayal contrasts sharply with the biblical Messiah, who taught that no one is expendable. In Jesus’ teaching, every life matters, enemies are to be loved, and compassion is both the means and the end. The ends never justify the means. Love is the mission. 

Who Is my neighbour? 

One of the deeper themes of the film is the tension between loyalty to those closest to us and responsibility to the wider world. Hunt’s enemies consistently try to exploit his love for friends and family, exposing it as a vulnerability. On a number of occasions, the villains kidnap or threaten someone close to Hunt in order to manipulate him. He is faced with the dilemma - to save the one he loves, or to save everyone else? 

At one point, a character offers this reflection: 

“We all share the same fate—the same future. The sum of our infinite choices. One such future is built on kindness, trust, and mutual understanding, should we choose to accept it. Driving without question toward a light we cannot see. Not just for those we hold close, but for those we’ll never meet.” 

It’s a powerful line—one that challenges narrow tribalism in favour of a universal compassion. In recent years, some have tried to co-opt Christian ethics in support of nationalism, prioritising loyalty to family, faith, and country above all else. But this film’s ethos cuts across that narrative. 

In an age of toxic patriotism and growing division, it’s striking that an international superspy like Ethan Hunt seems to offer a profoundly global vision: act not only for those we love, but for the good of the whole world—even at great personal cost. 

Hunt’s worldview echoes a deeply biblical theology: every person has worth, and we’re called to love our neighbour—including those who don’t speak our language or share our culture. The franchise promotes a genuine Christian ethic of sacrificial love. And why not? At the heart of Christianity is the story of a God who sent His Son on a seemingly impossible mission to save the world. 

It’s hard to miss the moral and theological framework that underpins Final Reckoning. It is, perhaps, this foundation that makes Ethan Hunt’s character not only thrilling but deeply human. Amid the explosions, stunts, and spectacle, Mission: Impossible makes us think, and subtly reminds us that the greatest mission of all might be love.
