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.

This City is Ours – truth and lies about the global drugs trade

The drug-dealing family drama reflects the impact of the drugs world.

Henry Corbett

Henry Corbett, a vicar in Liverpool and chaplain to Everton Football Club.

Family saga.

BBC.

I asked a thoughtful Scouser and cinephile “What do you think of This City is Ours? – the crime drama TV series set in Liverpool. I wondered if he would hate all the talk of drugs, the power games, the violence and that the series about a global trade is located in our city.

“Well, it’s true.”

As a priest in Liverpool, I have taken the funerals of drug dealers and users, including one where the family quoted me Jesus’ saying, “Those who live by the sword will die by the sword.” I have known too many people caught up first in the heroin trade of the 1980s and then more recently with cocaine.

I agreed that the series is truthful, and on many levels. Those involved in the criminal world of illegal drugs are still people.

I remember Peter (not his real name) who I knew when he was a young lad in the youth club I helped with. He was sitting in our kitchen with a mug of tea. He had bruises all over his face because of a drugs debt he hadn’t paid. One of my daughters came in to get something out of the fridge, and Peter apologised to her for the state of his face, explained it was because of being involved in drugs, and advised her strongly against it. He then asked after her interests and what she enjoyed and was ‘made up’ – happy - when she spoke of liking art. My daughter never forgot that conversation. She learned that people in the drugs trade were still people and could be kind, and that the illegal drugs world was to be avoided. People are both made in the image of God, capable of love and concern, and also flawed and able to be drawn into a trade that affects people so badly across the world.

So, the eight episodes of the first series of This City Is Ours show that the global criminal world of illegal drugs is brutal, violent and full of jeopardy. There are chilling deaths, executions, and vengeance. All truthful to that world. There are power struggles and a vicious family succession battle too. But there are also scenes of the same family at the dinner table, of the longing for a baby with a girlfriend who is very much loved. One moment a character is a hard-hearted killer and the next moment a tender partner. That is so truthful to the different compartments that people can live in: someone can be a loving son who cares for their mother and a ruthless power-hungry toxic gangster.

The consequences of that unnecessary “necessary” action are tragic.

A further truth that I see at every funeral is the ripple effect on partners, siblings, parents, the wider family, and friends, and outward across the community. Every episode of the show features family members: some in the gang, some outside the gang, some wanting a cut of the lucrative proceeds, others desperate to get out from this dangerous, chilling world. What we do can massively affect others close to us. So often family and friends, and a community, must live with the consequences of actions taken in a criminal underworld they are often excluded from and fearful of. Even young children can be affected and dragged into a battle for power.

So, there are truths, but what about the lies? Here’s two stand outs:

“Are we safe?” “Yes, babe.”

We know they are not safe. Definitely not. There’s a target on your back, and often on the family’s back as well.

And the second:

“It was necessary”. Or “f***ing necessary”.

No, it wasn’t. He didn’t have to become engaged in a succession struggle for power, money, and control. He didn’t have to kill someone he looked up to, respected, even loved. The consequences of that unnecessary “necessary” action are tragic.

Then there is the third lie about loyalty and trust. That false sense of being in a gang that will look after you and look out for you, that will secure your future and give you a sense of being someone who counts. From early on, this series shows that people are expendable, can be shot and tossed over a cliff, and that person you looked up to may be an informant to the police. That is maybe how they have stayed out of prison.

A fourth lie the series so truthfully nails is the notion that it is easy to walk away once you have seen through the attractions of money, of Spanish villas, of designer gear, of fragile power. It very often isn’t. You may desperately want a worthwhile life that brings good not bad, peace not killings, a freedom from looking over your shoulder and from a troubled conscience. But there may be money demanded by your supplier, there may be enemies you have made along the way. I have known people successfully move away from it all but that has often only been after a spell in prison, and with a sound alternative - whether a job to keep, a daughter to look after, or a move away.

Wisdom is a much-valued quality throughout history. Five of the Bible’s 66 books are often called Wisdom books and Jesus called Christians to be “wise as serpents and innocent as doves.” This City is Ours is beautifully shot, expertly scripted, brilliantly acted, and it truthfully lifts the lid on the world of the drug-dealing criminal underworld and on some of the lies peddled in that world. And I did explain in the funeral service that when Jesus said “Those who live by the sword will die by the sword” he was not recommending that way of life but warning against it.
