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.

Worry: bug or feature of our lives?

The ancient root of common or garden worrying.

Climate change, smartphones, a loss of social cohesion: these are just some of the potential culprits for an oft-discussed, much worried about, anxiety epidemic. But what if our worries can’t be fully explained by any particular feature of the modern age? What if worry is in fact an ancient problem that afflicted the first  century no less than the twenty-first? What would that mean for how we should respond?

I’m not a psychologist, or a social scientist, but I am a common or garden worrier. And worry worms its way into my life through the gap between responsibility and control. 

I first encountered this at work. As someone who organised events, I felt responsible (and would be held responsible) for how many people signed up. But I soon came to the painful realisation that I didn’t control how many people signed up. I had responsibility but not control - and worry wormed its way in through that gap. And that didn’t seem fair to me - it seemed like a “bug” that should be fixed. Maybe my bosses just needed to relax a bit. That way my responsibility would shrink to match my control. Or maybe I needed better comms, better marketing - some way of making sure people came.  That way my control would expand to match my responsibility. Either way, the gap between responsibility and control should be eliminated somehow.

And then I had kids - three of them. As a dad I am responsible for my children. But I am not in control of them - sometimes I can barely get them to eat their tea. And so worry worms its way in - through that gap between responsibility and control. But I began to realise that when it comes to my kids, I just can’t close the gap and I shouldn’t even try. To abdicate responsibility or to seek control are just two different flavours of failure. The gap between them isn’t a bug in the code of life, it’s a feature. It’s part of being human, and so human flourishing means learning to live well with, even in, that gap. But how?

In the earliest record we have of Christians trying to explain themselves, a book of the Bible called (confusingly) Acts, we follow Paul, convert to Christianity, to Athens, the cultural capital of the ancient world. And there he meets people different from us in almost every way… except that like us they are worriers. And they are worried because they feel responsible for something they can’t control. Paul finds an altar with this inscription “to an unknown god”. What makes people erect an altar to an unknown god? The worry that worms its way in between responsibility and control. We’re not sure if we know about all the gods - we’re not in control. But that god we don’t know about might hold us responsible. So let’s try to close the gap by erecting an altar to a god we don’t even know.

Paul offers a better solution - to them and to us. He’s invited to give a speech to the leaders figures of Athens, but he doesn’t present his audience with a more sophisticated technique for closing the gap between responsibility and control. Rather, he introduces them to his God, to the truth that allows us to flourish in that gap. This God, Paul says, marks out the appointed times and places of all people: that is, he is in control of all things. This God, Paul says, wants everyone to seek him and find him: that is, he wants the best for all people. This God, Paul says, doesn’t need anything from us: that is, our responsibility is his invitation to be part of what he’s doing in the world. Know this God, trust this God, Paul says, and you can see the gap between responsibility and control as a feature of life and not a bug. You can flourish in and not worry about the gap.

But how does that work in the midst of tea-time tantrums and the day-to-day worries of life? Well for me, on a good day, it works a bit like this. When I’m confronted with the reality of quite how much is beyond my control, I’m not faced with chaos. I’m just faced with the fact that I’m not God, but God is - and nothing is beyond his control. And the God who is in control when I’m not loves my kids more than I do, better than I do. And he doesn’t need me. He’s not delegated responsibility for my kids to me because he’s too busy to look after them himself. I’ve been given the responsibility of being their dad so I get to share in the joy of watching them grow into all they were made to be. The gap is still there - I’m really responsible and I’m really not in control. But maybe I’m ok with that.

There may well be certain features of the modern age that heighten our anxiety. But the people of first century Athens didn’t have smartphones or face climate change and they still worried. Because they felt responsible for something they didn’t control, just like we do. It’s an ancient problem, a feature not just of our culture, but of being human. And what if an ancient problem needs an ancient solution?
