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.

What’s love got to do with it?

Watching Lovesick, a surprisingly profound comedy about chlamydia, prompts Beatrice Scudeler to consider permanence in relationships.

This article contains spoilers for those who have not seen Lovesick. 

I was working on my English MA in 2019, just before the start of the pandemic, when a friend first told me about a Netflix show that had just aired its final season, Lovesick. The premise, I will grant, was not the most inspiring one for an unmarried, socially conservative graduate student whose only experience of dating had been an unfortunate three-day courtship with her at-the-time best male university friend.  

In Lovesick, Dylan Witter is the usual twenty-something-year-old: out of university, sort of purposeless, dating a string of women he thinks he’s deeply in love with, but breaking up with each of them no later than at the four-month mark. Unsurprisingly, he is diagnosed with chlamydia; shaken by the realisation that eleven years of sex out of marriage has left him with little more than sadness and a disease, he decides to meet with all of his ex-girlfriends, both to warn them that he may have given them chlamydia, but most importantly to try and figure out why he can’t find permanence in his relationships.  

From this point, Lovesick spends three seasons going back and forth between Dylan’s past and his present, building towards the final confrontation, at the end of season three, with his best friend Evie, with whom, he eventually realises, he has been in love for seven years. Along the way, we meet Dylan and Evie’s other best friend, Luke, who proposed to his girlfriend while still at university, was rejected, and now lives a sexually reckless lifestyle, as well as Angus, the kind-of-forgotten friend, who married a woman he didn’t really love, had sex with a maths student turned one-time stripper, divorced his wife Helen, and is now having a child with ex-stripper Holly. 

By the time we are out of university or school, it is unsurprising that our sense of certainty and purpose should crumble, when suddenly the burden of finding meaning is solely on our shoulders. 

Based on this description alone, you’d be forgiven if you thought this show quite a depressing drama, and certainly not one worth your time. In fact, it is a surprisingly profound, honest comedy about our generation’s struggle with the false promise of freedom, and our deep-seated desire for permanence, for a more sacramental view of reality. Dylan’s trials in his youth all point him towards the realisation that making commitments (whether that’s sticking to a career and becoming actually good at your job or finding permanence in a romantic relationship) is ultimately the one thing that makes life worth living. The writers of Lovesick would perhaps not put it this way, but this truly is a show about people who desperately need God, and fail without His guidance.  

The same applies to all of us, to those who are not Christians, but also to those of us who profess Christianity, but live as though we are atomised and self-sufficient (which we can all be tempted to do). When we are children, we have our parents to guide us; they are not a replacement for God, but they provide some guidance. Later, at school and university, it’s our teachers. By the time we are out of university or school, it is unsurprising that our sense of certainty and purpose should crumble, when suddenly the burden of finding meaning is solely on our shoulders.  

If we go to church, if we have a community in Christ to support us, the burden is somewhat lifted. But Dylan, Evie, Luke, and Angus have no such thing. They rely on each other alone, and, since they are lost, all they can do is commiserate each other about how difficult adult life is.  

Even so, the suggestion is there in Lovesick that there are moral standards external to our conscience, that there is something sacred and greater than us. In the very first episode of the show, Angus begins his ill-fated marriage to Helen. They get married in what is presumably an Anglican church, and Dylan makes a curious remark that, even though he’s ‘not religious’, a wedding in a church seems more appropriate. He laughs it off by suggesting that you have to sit somewhere hard and cold to really enjoy the ceremony, but it’s clear that he’s talking about more than this.  

What he’s experiencing is an intuition which I would guess is still in so many of us even in our post-Christian society, that is, the intuition that there is something sacred about promising to love and care for another person for the rest of your life, that it’s not merely a contract. It is a duty to uphold such a promise, and this is a kind of promise that ties us in love to what some people may call ‘the universe’, though what we really mean, who we really mean, is Christ.  

They have chosen to make an attempt at permanence, not to dismiss adult life as a senseless heap of broken people.

Sure enough, the rest of the show is about our protagonists watching all their significant relationships fall apart, and trying to rebuild them. I will have to spoil the ending for you, but that does not really matter, as it’s fairly obvious which direction the show is building towards from the very first episode. Angus is left alone as Holly leaves him, but vows to find a new job in order to provide for his unborn child. Luke stops engaging in promiscuous behaviour (sort of, he has seven years of trauma to deal with, after all) and begins a precarious, but genuinely caring relationship. After being hurt and hurting many people, Dylan and Evie decide that, in spite of all the heartbreak, and after a broken engagement, it is still valuable to make ourselves vulnerable to suffering for the sake of loving another person.  

The show ends with Dylan telling Evie that he loves her for the first time, and you can tell it’s the first time in his life that he has really meant it. They are not married yet, but we can guess that’s what will happen next. They have chosen to make an attempt at permanence, not to dismiss adult life as a senseless heap of broken people, but rather to decide to take away some of the brokenness by growing up, making a commitment, and standing firm.  

To marry during a pandemic, in the wake of my parents’ divorce, and uncertain about our future, was at once the maddest, and the best decision we ever made. 

 

Something I have not yet told you is that the first time I watched this show was when I first started dating my husband. Although I could not relate to the endless dating, I could relate to the fear, the uncertainty of whether the other person wants to care for you in the way we want to care for them.  

Not long after, I told my now husband that, if he didn’t think our relationship would lead to marriage, I’d much rather we break up and move on. I did not want Dylan and Evie’s seven years of suffering. I wanted marriage, I wanted commitment, I wanted a family. We did get married, around a year later, and after a year of marriage I watched Lovesick again. Now as a married woman, and having gone through the hardships of moving country twice, having a child after a difficult delivery, and facing problems in our extended family, I appreciated more deeply what a sacred and courageous thing it is to commit to sticking by one person, no matter what.  

To marry and have children, knowing how ruthless and un-beauteous the world can be, is exactly the act of bravery our society so desperately needs. I watched Lovesick for the third time just recently, leading up to our second wedding anniversary. It was my husband’s first time watching, and we could not help but reminisce about our courtship, and how, to marry during a pandemic, in the wake of my parents’ divorce, and uncertain about our future, was at once the maddest, and the best decision we ever made 

So, yes, watch Lovesick, even though it’s technically just a comedy about chlamydia. It may spur you to reflect on the real meaning of love: the fearless and unconditional caring for the other, regardless of their brokenness, but rather because of it. After all, that is how God loves us.
