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.

Last One Laughing: we’re less in control than we think

"Humour is human" and deeply strange.

Jonathan is a priest and theologian who researches theology and comedy.

Amazon MGM Studios.

10 comedians shut in a room. Last one to laugh wins. 

It’s a simple concept, and with the addition of a few gimmicks, including games and surprise guests, Last One Laughing delivers on it. The show isn’t creative – there have been at least 27 previous versions in various languages – but it is successful and is a much-needed boost for Amazon Prime, whose content has tended to flop recently. 

I enjoyed the show. It amused me, which is what it was supposed to do. I didn’t necessarily laugh out loud, and I think I probably would have enjoyed all the comedians doing their own standup better. Some of the comics have made their infectious laughter such a part of their charm that it was a bit bizarre seeing them crack jokes without having a giggle (I’m looking at you Bob Mortimer). 

But overall, I had a good time watching Last One Laughing. I was entertained and I would recommend it. Jimmy Carr is unusually likeable as a host, though I wanted to hear more from Roisin Conaty, whose role as co-host was almost non-existent. Richard Ayoade was his normal genius self. And there were a few genuinely standout moments: I think my favourite was Rob Beckett whispering to Joe Wilkinson “you’ve doing a really really good job of showing off, lots of funny bits."

In fact, as that moment suggests, the show is probably at its best when it gets a bit meta, as the comedians reflect on their own comedy and what it is like to be a comic. Moreover, there is a genuine warmth between everyone, and an appreciation of each other’s talents, which gives the show a particularly endearing tone. 

It’s good, mindless, not particularly clean (definitely not family friendly!), fun. 

So Last One Laughing doesn’t tell us much we don’t already know. It’s not supposed to. It’s light entertainment. 

Comics are funny.  

Often the unexpected makes us laugh. 

Not laughing can be very hard. 

This last point, though, is perhaps worth thinking about a bit further. It is familiar to everyone. Who hasn’t felt the physical pain of trying to restrain the giggles in a moment when we really must not laugh? 

 But this is one of those things that is so familiar we often miss how strange it is. 

Philosophers since Aristotle have speculated that laughter is one of the things that makes humans unique, since we don’t know of any animals that laugh. Whether the claim about human exceptionalism is correct or not (and I confess I remain agnostic about this), it does seem that laughter is a practically universal experience of human beings. As Philosopher Simon Critchley puts it, “humour is human.” 

But if this is true, then laughter as a phenomenon also highlights some of the eccentricity of our humanity. For, as Last One Laughing shows us so clearly, laughter is only ever partially under our control. 

Our bodies, our spirits, even our minds, can betray us at any moment. That something we don’t want, even something good like laughter, can erupt from within. 

We often like to imagine ourselves as rational beings, whose lives are characterised by making informed and free choices. We think we are in charge, at least of ourselves, and that we move through the world intentionally, with purpose and direction. 

And yet, into this nice picture of a life under control, laughter breaks in, often uncontrollably. Our muscles spasm. Our eyes stream. Our vocal cords erupt in strangely animal snorts and grunts. 

The fact that professional comedians and actors can’t maintain a straight face, sometimes in the face of their own jokes (take a bow Daisy May Cooper), should remind us that there is much in ourselves that is beyond our conscious control. Our laughter almost always has cognitive content. It involves our minds. We laugh at things. 

But it is always embedded within a body. Laughter, with all its bodily shakes and muscle twitches, sometimes just can’t be kept in, no matter what our minds and consciousness tells us. 

Christianity has long been aware of our lack of control. Paul, writing to the church in Rome, lamented that “I do not do what I want to, but I do the very thing I hate.” St Augustine, one of the greatest theologians of the Western Church, wrote in the fourth century that “I had become to myself a vast enigma.” Martin Luther, the sixteenth century German theologian, began the Reformation and changed history, in part over an insistence that we are far less in charge of ourselves than we like to think. 

Yet such writers do not counsel despair. Instead, they allow our lack of control to point to our need for God and his help. Paul, a few verses after the previous quotation, cries out: “Wretched man that I am! Who will rescue me from this body of death? Thanks be to God through Jesus Christ our Lord!” 

Now, for all these authors, the stakes are high – they are talking about sin, death and damnation. The comedians in Last One Laughing are playing a much more relaxed game, all that they stand to lose is pride. Yet they too, one by one, discover that they “do not do the thing they want.” 

And so, they are learning a version of a Christian lesson – that we are less in control of ourselves than we might like to think. That our bodies, our spirits, even our minds, can betray us at any moment. That something we don’t want, even something good like laughter, can erupt from within. 

Now most of us, most of the time, probably enjoy the uncontrollability of laughter. It’s one of the things that make comedy enjoyable, both to watch and to perform. But it should maybe make us aware of other, less benign losses of control. Or at the least it should remind us that there is much in us that escapes our attempts at self-mastery. 

Last One Laughing reminded me that laughter is stranger than we think. Just as I am stranger than I think.
