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.

Race across the world: you can go fast and go far

Forget the tight travel connections; it’s the human ones that enthral us.

Lauren writes on faith, community, and anything else that compels her to open the Notes app.

Ready to race.
BBC.

After years of peer pressure, my husband and I have joined the bandwagon and become Race Across the World evangelists. The BBC series, currently in its fifth season, follows five competing duos on an expedition between far-flung locations with limited resources and no forward planning.  

Viewers love the show wherever they are in the world. In America, The Amazing Race, which has a similar format, is now on its 38th series. 

‘No flights, no phones,’ boast the rules – but Race Across the World is a far cry from retreating to simpler times before smart devices and online banking, nor does it shy away from the complexities of modern life. Though there is a cash prize, the format of Race Across the World prioritises connection over competition. Each episode is a picture of messy, frantic humanity and examines how we cope in an environment where all we really have is each other.  

The challenge is real. In the current series, the couples trek across China, Nepal and India, the start and end checkpoints spanning more than 14,000km. This cohort is an eclectic mix: two sets of slightly estranged siblings, teenage sweethearts from Wales, former spouses and a mother and son. Their vulnerabilities, as well as their triumphs, take prominence. In their conversation and in confessional, each person demonstrates a remarkable willingness to face the hard stuff of life with resilience, tenacity and enough convivial spirit to please the production team. 

This emotional depth maps the physical and logistical demands of the race, as the viewer follows the pairs’ fast-paced journeys, stopping occasionally to enjoy some wonderful view amid countless train stations and overnight busses. 

My sympathy derives from a belief that I would fare horrendously as a contestant – I think my excellently organised, exceedingly patient husband would flat-out refuse to compete with me. But the wider response to Race Across the World is one of empathy. Unlike similar shows, we are not called to blindly favour for the frontrunner, but to enjoy spending time with and bearing the burdens of all. We feel every frustration of the missed shuttle that just departed. When the ferry disembarks late due to poor weather, our response is not to scoff, but to share, in some small way, their lament. As their successes and failures are magnified, so is our compassion, willing them not to get lost in comparison’s snare but to keep moving forward. 

Race Across the World exhibits the reality of community, speaks to the ache of life’s unpredictable nature, and extends grace for struggling humanity. We learn, alongside those racing, that the point is not always to fix our frustrations, but in being able to sit with them, to acknowledge disappointment rather than dismiss it, and to allow setbacks to spur us onto the next step. Sometimes, things get hard and we acutely feel that a situation is beyond our control. What have we then? Still, each other. Still, communion. Still, God. 

Most of the time, the competitors’ issue does not disappear; they arrive at the checkpoint 24 hours late, they board the wrong train, the persistent typhoon ruins their chance of first place. But this hardship renews their strength and determination, promoting the notion that while suffering is never easy, it somehow shapes us. We endure and, in that endurance, we are refined and strengthened in ways we never thought possible. In the testing of our own endurance (or lack of), it turns out that some things actually are immovable. 

This resilience permeates to the heart of who we are, forming us into people who can carry disappointment and hope simultaneously. It is an unwavering, defiant hope that finds us and never leaves us stranded. From this new position, fresh possibilities arise out of a deeper satisfaction, a greater victory, than found in being first place. This hope is rooted in something deeper, and it cries from the other side of difficulty: ‘Here I am, not lost.’ 

In his poem, Vow, Roger McGough reminds us that when, 

Things seem to go from bad to worse,  

They also go from bad to better …  

Trains run on time,   

Hurricanes run out of breath, floods subside,   

And toast lands jam-side-up.’ 

It speaks to how the relatively small disappointments help us cope with the bigger stuff of life, the stuff we feel we will not emerge from. In the gritty, heavy, unfair stuff of life, we appreciate the weight of the enduring hope we possess, manifested in the belief that things not only can, but will go from bad to better. This is not a fragile optimism, but a fortitude and faith that sees the world as it is yet maintains that good and better is possible. 

In the same way, Race Across the World urges us to consider what we can handle – not in our own strength, but in community, in reliance on another. Though our complex, strained humanity may attempt to deter us, life’s hardships are eased when shared, whether on a televised journey or from our sofas. We are strengthened in, by and through devoted community. In keeping pace with another – slowing down or rushing to keep up – we are mutually inconvenienced, and that is a source of beautiful fellowship. In letting go of the things that enslave us to self – ambition, insecurity, pride – we encounter the gift of each other, and give life to love that serves. We commit to community; we choose connection over competition. 

The saying goes, ‘If you want to go fast, go alone. If you want to go far, go together.’  In Race Across the World, significant effort is understandably made by competitors to go fast and to go far, to place first and take home the cash prize. But the viewer’s delight is not so much in seeing the winning duo cross the finish line, as in witnessing the journey of two muddling through, sharing the load, bearing burdens and multiplying joys. 

In our lives, too, the road can be unpredictable, full of detours, missed buses and, yes, a few painfully overpriced cabs. Yet it is in the community of fellow travellers we learn the worth of endurance, the refining possibility of suffering, and the hope that is cultivated in its place.
