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.

My conversation with... Frank Skinner

Re-Enchanting... Comedy. Frank Skinner is only interested in the weird. In the un-graspable. In the outrageous. Belle Tindall gets a lesson in "super poetry" from Frank.

Around a table with microphones, three people record a podcast, one leans in talking and gesturing with a hand while the others listen.

Recording Re-Enchanting... Comedy.

In David Baddiel’s (admittedly excellent) book The God Desire, he has a section on his long-time friend Frank Skinner entitled ‘In a Car with Frank Skinner and his Sins’ (not that Frank would know; he’s refused to read it). After my conversation with Frank Skinner for the Re-Enchanting Podcast, I’d like to similarly entitle this piece ‘On A Rooftop with Frank Skinner and his Doubts’.

Frank Skinner; a comedian, broadcaster and author who has entertained millions through TV shows such as Fantasy Football League, The Frank Skinner Show, Baddiel and Skinner Unplanned and Room 101, as well as many sell-out stand-up comedy tours. His penmanship is also a force to be reckoned with, having crafted the undeniably iconic Three Lions football anthem (which he penned with the afore mentioned Baddiel) as well as my favourite piece of his work, A Comedian’s Prayer Book. He’s always been open about his Catholic faith, determined to ‘keep his hand up’ as a (very often the) Christian in any given room. Frank’s faith has been, and still is, shot through everything he does – even his ‘sinning’.

This conversation was always going to be interesting.

And as such, there are many things one could take away from this conversation with Frank. Perhaps the value he places on doubt as a tool of refinement and source of growth, or his comparing of Richard Dawkins and Christopher Hitchens to bullies at a Christian disco, or even his efforts in ‘responsible sinning’. It’s a fascinating conversation from beginning to end, as I rather embarrassingly told him to his face, I enjoyed "every moment of it."

However, there was one salient question that was left lingering in my mind days after our conversation ended – are we (by ‘we’, I mean Christians) interesting?

There’s been a theme that’s run through Re-Enchanting thus far, prevalent in our conversations with Jennifer Wiseman, Paul Kingsnorth, Francis Spufford, and now Frank Skinner. And that theme is this: in the context of our 21st Century cultural moment, Christianity is profoundly weird, and that weirdness is the very basis of its power. It cannot, and should not, be blended into the so-called secular moment we find ourselves in. This is confronting for me, someone who has admittedly spent her life watering down the ‘oddest’ parts of Christianity (only in public, I should state) in an attempt to make it more palatable to my secular peers. As a result, I’ve ashamedly become the type of Christian that Tom Holland would tell to ‘grow up’. Well, if one finds themselves somewhat disillusioned with such a boring ‘no-man’s-land’ of compromised belief, this episode is certainly the perfect antidote. In fact, this entire series is.

Frank is only interested in the weird. In the un-graspable. In the outrageous. The way he speaks of interactions with his (beloved) atheist friends made it seem as though atheism is one of the most obvious things one could claim to be, meaning that there’s nothing particularly interesting about it:

“There’s something I find a bit confusing about people in the 21st century saying “this is how daring I am – I’m going to come out as an atheist”… atheism given over as if it’s a brave stance. I’ll show them a brave stance, and it’s not atheism.”

Speaking , in comparison, of sitting in Mass in his local church, looking on as his priest holds up a piece of wafer declaring that it is the Saviour of the world, Franks says,

“in the 21st Century, the idea that there’s a God, that he’s got a lamb, a representative that came to earth, that he takes away the sins, and that here he is in this bit of wafer… it’s outrageous. I don’t like the idea that we have to go to them (atheists). It’s made it (Christianity) a dull half-way house."

Hence this lingering question: are Christians actually the more interesting ones? My conversation with Frank made me think that we may just be.

Even though, as I have mentioned, the entire conversation was one to remember, it was the final five minutes that that truly ticked the ‘re-enchanting’ box for me. Justin and I, along with our guests, have often discussed Christianity as ‘the greatest story every told’, but Frank introduces us to Christianity as a

“living poem, super poetry, poetry that’s physical, poetry made flesh, poetry that actually exists.”

And not only that, but

“we are a part of that poem, we just need to step into it. There is a blank line waiting for us…”

How beautiful. It’s clear that, to Frank Skinner, Christianity is not only very interesting, it’s profoundly enchanting. Listen to the first episode of Re-Enchanting Season 2 enjoy Frank’s disconcerting ability to make you simultaneously laugh lightly and ponder deeply.
