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.

Fun is dead

When video games turn play into work, we need to play without fear of consequences.

Imagine there’s been a sudden change in plans. The evening meeting is cancelled at the last minute, or your friend is sick and can’t come round. There are no looming tasks that need doing, so you set out to have some fun. What do you do?

Karen Heller’s recent article in the Washington Post suggests that we don’t really know how to answer that question. ‘Fun is dead’, proclaims the headline, and her analysis is simultaneously insightful and depressing. Weddings have become stressful extravaganzas, holidays require a constant stream of activity, retirements should have a purpose and a plan. Our fun, our play, requires a reason to exist. Can we have fun without it having some larger purpose? Can we play without needing to post it on social media? Everyone else, it seems, is having much more fun than we are.

Take video games. You might think this ought to be the very definition of a playful activity, one with no particular end or purpose in mind. But even here, it seems we don’t know how to have fun without some type of incentive. Conversations about video games online are frequently so self-serious and toxic that you’d be forgiven for thinking that it was a matter of life and death, not differing preferences about fun. Some of the world’s biggest games – things like Fortnite, Genshin Impact, and EA Sports FC – give rewards to players who turn up to play every day. It sounds generous until the psychological hooks of these methods grip you far past the point of fun. Players talk about not being able to sustain more than one of these types of games, because otherwise they won’t be able to keep up. What starts as play quickly turns into a form of work.

The world of play is a world of grace, where we are free to find pleasure in an activity on its own merits.

I am as much a sucker for this method as the next person. I find myself drawn to games which start out as free and fun, but the fun inevitably seems to turn into a chore that I cannot dislodge. There is an unwritten pressure to turn up to play every day to complete daily tasks and keep up with the competition. I end up feeling guilty for wasting my time playing games, and anxious to keep up with what’s required when I do. No wonder, with all these contradictory pressures on play, I find myself more often than not vegetating in front of Netflix rather than really playing.

This is all a bit of a first world problem and might seem like another depressing indictment of modern society, but perhaps it shouldn’t be that surprising. As humans, we are always looking for some way to justify ourselves, some way of finding proof that what we do matters. Play, by contrast, demands that we step into a different sort of world. The world of play is a world of grace, where we are free to find pleasure in an activity on its own merits, and not for anything we might get from it in the end. Play, in its best sense, is purposeless apart from the joy of playing. "When we try to give our playful activities some wider purpose for why they matter, we are turning them into something else."

The world of the Christian faith is not often seen as a playful one. It seems so very serious, dealing as it does with matters of life and death. But within the serious world of the Church, a space for play emerges. After all, it is first and foremost a world of forgiveness from what we have done wrong in the past, present, and future. This forgiveness takes away the fear of failure. Whether I am greatly successful or not I am loved and forgiven by God. This is God’s gift, which cannot be earnt and cannot be lost.

The result, perhaps surprisingly, is that I am free to play, because I do not need my play to achieve anything for me. As the theologian Simeon Zahl puts it,

In play a person is free to engage with the world creatively, actively, energetically, but without fear of ‘serious’ consequences. The Christian is free to play with things that once seemed deadly serious, to find delight in what were formerly objects of fear, and to take themselves much less seriously.

In the world of video games, this idea is perhaps most clearly seen in the games produced by the Japanese game developer Nintendo. Their games, from Mario to Zelda, epitomize a vision for gaming which is driven by creating joy for whoever is playing, and not unnecessarily burdensome tasks. One of their best games of last year, The Legend of Zelda: Tears of the Kingdom, doesn’t offer a prescriptive path for how players should approach its challenges. Instead, the player is given a toolkit and set loose to use it in the world as they see fit. The result is a sense of joyful freedom, a feeling that its world is full of delight and even silliness. It gave me some of the most fun playing games in recent years, without me even coming close to finishing it.

It's this playful attitude that I want to take into the rest of my life. What would it look like for us to see the world as a playground rather than an exam hall? The result wouldn’t just be a lot more fun. I think it would also be deeply Christian.
