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.

'The smell of dust and damp stone will always cry “safety!”'

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.

'Do you guys ever think about dying...?' - Barbie

Pat Allerton reflects on the Barbie movie, the societal questions that it answers and the existential question that it doesn't.

Margot Robbie as Barbie in Greta Gerwig's Box-Office smash hit movie

So I’ve just got home from watching the brand new and much acclaimed ‘Barbie’ at the cinema (don’t worry, I also watched ‘Oppenheimer’ last week). It’s 11pm, my wife and our 8.5 month old daughter are asleep upstairs and despite having church in the morning, I feel stirred to write some thoughts.

First and foremost, huge congratulations to Margot Robbie, Ryan Gosling, the whole cast, crew and team. It’s an absolute belter! Full of laughs from beginning to end. I thoroughly enjoyed myself and would encourage anyone else to go and see it.

But secondly, far from being the shallow, plastic cliché that you might expect, what you actually get is an intelligent, searing critique, albeit somehow gently done, of the world we live in and what’s predominantly wrong with it. Which is, you guessed it, men. Or more specifically, patriarchy.

The film begins in ‘Barbieland’ where everything is seemingly perfect, as encapsulated by Barbie when she describes the day we first meet her as, ‘the best day ever. So was yesterday, and so is tomorrow, and every day from now until forever.’ That is, until we meet Ken (played by the excellent Gosling). It is here that the first inkling of imperfection or wrinkle in their world is detected. As the narrator (voiced by Dame Helen Mirren) makes clear, ‘Barbie has a great day every day, but Ken only has a great day if Barbie looks at him.’ (We’ve all been there guys). His niggling insecurity and consequent competitiveness towards other Kens however, still aren’t enough to wake Barbie from her dream-like state and reveal that all is not well in paradise.

Issues of equality, respect, independence and identity are addressed in a way that left this 'pale, stale male' challenged but not condemned.

That moment arrives unexpectedly, during what appears to be a standard evening with ‘a giant blowout party with all the Barbies, and planned choreography and a bespoke song’ to which Ken is told he should ‘stop by’. The dance is breathtaking, the happiness palpable, and yet suddenly, as if from nowhere, Barbie blurts out the pivotal line in the film, the hinge on which the whole (Barbie) world turns, ‘do you guys ever think about dying?’ Cue the DJ’s vinyl record screeching to a halt, the choreography closing down, the dancers looking at her in disbelief, and the general sense of a serious buzz-kill. ‘Dying to dance’, she disingenuously adds, desperate to keep the party going, to shrieks of relieved delight and Dua-Lipa's return. Disaster averted, reality restored.

Except it’s not, it’s simply avoided. Avoided by everyone that is, bar Barbie. Something has changed for her, she knows it, and she must somehow find out why. That wrinkle in her world (along with the wrinkle on her thigh) turns out to be caused by a tear in the fabric separating her plastic world from the real one.

Long-story short, avoiding spoilers where I can, Barbie and Ken then embark on an eye-opening, perspective-shattering, journey from their world to the real world in order to find out where such unnerving questions (and cellulite) were coming from. Major issues with (or norms within) our world are encountered, from the objectification of women (Barbie receives immediate unwanted attention from all kinds of men), to the totally unmerited respect of any man (with someone even asking Ken if he had ‘the time’). They each go on an existential journey of discovery, with Ken delighted to learn that in the real world, men rule the roost (except for a brief time when he thought that horses did). Inspired with fresh vision, he quickly returns home in order to make some fundamental changes to and establish much of the best practice that he’s witnessed in patriarchal L.A.

I won’t say how things end up, but suffice it to say, issues of equality, respect, independence and identity are addressed in a way that left this ‘pale, stale male’ feeling both challenged but not condemned. Kudos to the team for getting that balance right! However, as big and important as these issues are, and as satisfying an ending as was reached from a social justice warrior’s point-of-view, it struck me that the biggest elephant of all was still left there in the room, or at least charging around on the beach. Because the very question that began her journey, the deepest one that woke her up, is the very one that’s just left hanging, unaddressed and ungrappled with.

The music stops and that is it. And yet don't our hearts long for more?

It’s almost as if that moment of existential angst on the dancefloor (and who hasn’t had one of them), realising the fragility of our own mortality, did nothing more than focus Barbie on the need to lay hold of everything she can in this life, rather than exploring the reality (or not) of the next. Our culture has a word for it. YOLO, if you didn’t know, standing for ‘you only live once’. Which of course is true, whether you’ve got faith or not. But the Christian worldview would go further, saying that whilst indeed you only live once, the Scriptures tell us that you also live forever (or YALF, to coin a phrase). Which sounds ridiculous on the face of it (the concept, not the phrase, although granted, YALF might not catch on). After all, as the creator of Barbie, Ruth Handler, tells us in the film, ‘ideas live forever, humans not so much.’

Unless, of course, they do, or can, which only our creator could possibly make possible. And so Ruth’s appearance raises another interesting question, if she made Barbie, who made Ruth? Only when we’re dealing with questions of this nature can we be positioned to take on the big mama (I was tempted to say ‘daddy’) question of, ‘do you guys ever think about dying?’ Which, of course, every one of us does. You can’t be human and avoid doing so. You’d have to be a doll in a made-up world.

But it’s a frightening thing to do, whether in Barbieland, in England’s green and pleasant land or anywhere for that matter. Because it all just looks so final. Like the music stops and that is it. And yet don’t our hearts long for there to be more? For one more song, for the beat to continue? Dare we hope for resurrection where life and light beat death and darkness? Because as beautiful as this life is, with all its opportunity for growth and freedom, be it in self-revelation and actualisation like Ken (the film ends with him wearing a hoodie that says, ‘I am Kenough’), or greater progress and equality on a socio-political level, experience tells us that until we have an answer for Barbie’s first and biggest question, then our own days here on earth, however good, happy and choreographed, will always be rudely interrupted by the reality of death and its long shadow. Find an answer for that... and let the DJ’s music play.
