Proust Effect

Posted on by Jinavie

In his novel In Search of Lost Time, French writer Marcel Proust explored the power of smell in invoking memories. He tells a story of how he would have tea-soaked madeleine to trigger memories from his childhood. Proust called these memories involuntary memories, because it is not recalled on purpose, but automatically triggered by a sensory stimulus such as smell.

Our brain processes memory in a strange, abstract way. Because it doesn’t record memories like a photograph or video, memories become unreliable the older they are. We have very limited memories of our childhood, unless they are paired with specific emotions or memorable events.

Smell triggers involuntary memories because the part of the brain that senses smell, the olfactory bulb, lies right next to the hippocampus and amygdala. These sections of the brain handle memory and emotion respectively, so there is a theory that we form memories linked to different smells, especially if it is an emotional one. There is also some research to suggest a phenomenon called reminiscence bump, where we have a tendency to recall more triggered memories from adolescence and early adulthood. This may be because these are the years when we form our self-identity.

This may be why smells of certain dishes or baking may act as powerful mediums to recall treasured childhood memories, such as the love we received from our parents. Even as adults, we all have specific dishes that we crave to comfort us when we are feeling stressed or lonely. More often than not, these dishes will have a story behind them, whether you remember it consciously or not. When we smell the dish being prepared, we become drowned in nostalgia. The emotions of happiness, safety and love linked to these memories distract us from the pains of life for just long enough that we can have the strength to make it through another day.

Proust talked about a tea-soaked madeleine being his key to his memories. What food is the proverbial madeleine to you?

What food triggers your nostalgia?

The Importance Of Television

Posted on by Jinavie

Fire is considered one of the most important discoveries in the history of our species. Since the dawn of time, it has provided us with warmth, light, cooked food and the power to invent even more things.

We can see how important fire was to our ancestors from how integral it was within a house.
In prehistoric times, there would always be a fire at the centre of a cave or hut, where the family could gather around for warmth and light. Here, they would warm themselves on a cold winter’s day and cook meat that they hunted during the day to tenderise it.

Unlike the old days, we no longer have open fires in the house. Instead, fire has been split into three different forms.

  • Instead of huddling around an open fire for warmth, we have boilers and hot water cylinders to warm our houses.
  • Instead of cooking our food over a campfire, we have gas or electric stoves and ovens.
  • Instead of the flickering flames providing us with light and distraction, we have television and computers.

Of course, we still have fireplaces, barbeques and candles, but the modern person tends to rely more on modernised versions of fire.

An interesting takeaway from this theory is how television is the modern form of the psychological comfort that fire provided us. In prehistoric times, people would struggle to stay alive, running from predators and hunting to feed the family. Looking at the fire mindlessly at the end of a hard day’s work would have been a way to destress and unwind.

Nowadays, most of us are lucky enough to not have to fear death on a day-to-day basis, but we still suffer constant stress from the busy modern life. Perhaps sitting in front of a television or computer to procrastinate for half an hour is not the worst thing in the world.

That said, everything should be done in moderation. It is good to relax for a set amount of time, but if you spent every evening after work staring at a screen without an original thought, your mind will dull and atrophy.

So, it is good to balance out the mindless entertainment such as comedy or reality shows with films that provoke thoughts and emotions, documentaries that provide you with knowledge, and shows that stimulate your creativity.

Most importantly, what you think and feel and learn after watching these should act as fodder for conversations that help deepen your connection with other people.

Time Divided

Posted on by Jinavie

Even though time is continuous, we like to think of think of time in segments.

The most basic unit is the year. Every time the Earth rotates once around the Sun, we take stock of the year gone by, while setting resolutions for the next year. Technically, whether it is 300 or 400 days, time has passed, yet we always mark changes by the number of years. For example, we use age as a marker of what stage of life we should be at (even if it is not a very accurate marker).

Another classic example is the four seasons. The making of accurate calendars and units of time was critical in the development of agriculture as it allowed us to plant many different crops with high efficiency and yield. In older times, people may have marked time by reminiscing what happened around the time of the last harvest while eating food made with ingredients harvested at that time.

Some segments are less regular, such as the last time you caught up with someone, or whenever you have a big life change such as moving cities. Some people may mark the chapters of life by the person they were dating at the time, or the stage of professional development, such as what year of university they were in.

Why do we obsessively divide time and remember our lives in artificial, bite-sized chunks? Our brains are very good at noticing patterns and change, but not so good when the changes are gradual and continuous (change blindness). Ergo, dividing up time into segments help us process the past.

It is hard to notice how much someone’s hair has grown if you see them every day. It is hard to notice how different you and your partner have become with time until a conflict arises. It is hard to notice how much we have grown and matured and changed without consciously reflecting from time to time.

Another interesting thing to consider is that what you use as a marker of time may suggest what you are prioritising. When you look back, what is the unit of time you use to divide your life? Is it the last time you moved cities? Your last boyfriend or girlfriend? Your last big trip? A moment where you came to an epiphany?

Whatever it is, it is a useful practice to periodically look back on all the segments that make up your life, such as by keeping a journal and reading it later. This will let you be more aware of how you are developing as a person and help you steer yourself in the general direction that you want your life to take you. At the very least, it is amusing to notice the subtle differences between the past and the present you.

Day By Day

Posted on by Jinavie

How was your day? Did something good happen that made you feel happy? Or were there a series of dramas that left a sour taste in your mouth? On average, the answer to the question is almost always just: “it was fine”.

For most people, the typical day tends to be a working day. We wake up, fix breakfast (hopefully), go to work, do the same work we have done for years, come back home, try to relax as we brace for the next day, then go to sleep. People tend to feel worn out and tired after a hard day of work and are just looking forward to the next weekend or the next vacation.

But this means that we are looking forward to only (at most) 10-20% of our lives. The other 80% of our days, we are surviving instead of living. Isn’t this such a waste? We only have a limited amount of time on this Earth, with even fewer years where we are young and full of vitality. Yet we spend the majority of it looking forward to just a small portion of it.

This presents a few problems. For one, we set high expectations for our days off, which can result in disappointment if things don’t go as planned. Sometimes, we feel so exhausted from our work days that we waste our precious free time binging TV shows or scrolling through social media. In essence, because we split our lives into “miserable working days” and “hopefully enjoyable resting days”, we become very inefficient when it comes to living happy lives.

One solution is to find a way to make your typical days more enjoyable. You have to try to find a routine that you wouldn’t get tired of. This might mean finding a job that continues to challenge you in different ways, finding a passion that keeps you interested and motivated to improve yourself, or finding a life partner who you never get sick of talking to and spending time with. These are all achievable, but nonetheless difficult because of the limitations set by reality. Then again, they are well worth trying for.

The other option is changing the way you reflect on your life. A major barrier to happiness is that our brains always focus on only new or negative things. That is why when we look back on our day, it feels featureless and mundane because it will either be routine, or a bad situation overshadows the whole day. To fight this, we have to consciously remind ourselves of the few good moments.

Think of one thing you did well today.

Think of something you were grateful for today.

Think of something that made you smile today, no matter how briefly.

These are all simple questions that will remind you that a typical day is really not that bad if you change your perspective.

Happiness is not a climax that you reach from stimulating yourself with new experiences and excitement. It is a state of mind, a perspective, a way of life. If you seek sustainable happiness, find a way to make each day – no matter how routine it is – more enjoyable, whether by changing something in your life or changing the way you view your life.

For Versus With

Posted on by Jinavie

What do you look for in a potential partner? Everyone has their own set of criteria and features that they find attractive. But a common point of the things that people look for in a potential mate is that they subconsciously ask the question: “What can this person do for me?”.

Let’s take some examples.

  • “Someone with a good, stable job” – Someone that offers me financial stability.
  • “A tall, dark, handsome guy” or “A beautiful, sexy, blonde girl” – Someone who is aesthetically pleasing for me to look at.
  • “Someone who can cook well” – Someone who can feed me.
  • “Someone that makes me laugh” – Someone who will make me happier.
  • “Someone who makes me feel loved” – Someone who will make me feel special.

As individuals, we are allowed to make some selfish decisions when it comes to important life choices. But a relationship involves two individuals, meaning that both parties should be considered. There is some room for compromise, but the more selfish and individualistic people act, the more resentment that builds up in the relationship.

Furthermore, the question of what your significant other can do for you builds expectations. Human beings never act predictably, so this is sure to lead to disappointment. As you get used to each other’s company and your partner starts doing less “for” you, such as cooking you dinner every day or giving you gifts, you will feel as if they don’t love you anymore. Eventually, you grow apart from each other and the unrealistic expectations threaten the relationship.

Perhaps the more important question to ask is: “What can I do together with this person?”.

For example, what hobbies or passions do you share and can you do it together? Do they spend their days off in a similar way to you? Are your values and beliefs aligned in a way that you could share a life together without too much clashing? How are they different from you, what can you learn from them and how can you help them?

The advantage of this question over the first one is that it respects that a relationship is something shared by two equals. Instead of asking what value your partner will add to your life, it instead asks how you can add to each other’s lives to produce something greater.

1 + 1 = 3

Exoskeleton

Posted on by Jinavie

If you look at a crustacean, such as a crab or lobster, you will notice that they have a very tough exoskeleton. Unlike us, they have their skeleton on the outside to act as armour to protect their weak, soft insides. This allows for great protection against injuries and when battling.

But if they are contained in a rigid shell, how do these animals grow? The answer is that they moult. As they grow, crustaceans will periodically shed their armour, so that the growing inner tissues can create a larger exoskeleton to hold their body in. This is a critical period as the animal is most vulnerable, as the new exoskeleton is still soft and does not offer much protection.

Even though human bodies contain skeletons on the inside, we could consider our hearts as having an exoskeleton. Like all animals, we want to avoid pain – both physical and emotional. So as we grow up, we put up resilient walls to try to protect our weak psyche and ego, to prevent being hurt by others. But a heart with a rigid, hard shell cannot grow. Only when we lower our guard, climb out of our shells and allow ourselves to be vulnerable can we grow and mature.

Life is full of suffering and hardship. We all have our scars and traumas, but at the end of the day, we survived. If we decide to shut ourselves in to avoid connection and refuse to open up to others, we may protect ourselves from some pain. But these are the moments – when we feel like all is lost, when we feel so weak and helpless, when we are anguishing – that we are growing as a person.

Don’t be afraid of feeling weak and vulnerable – it is a necessary step for your heart to grow.

Brocken Spectre

Posted on by Jinavie

There is a Scottish legend that speaks of a terrifying giant that lives atop Ben Macdui, the second highest peak in Britain. Am Fear Liath Mòr (Gaelic for “Big Grey Man”), is describes as a gigantic, dark figure with a fuzzy appearance. It is said to inspire a feeling of fear, eeriness and apprehension. It has been sighted by multiple lone climbers exploring the peaks of Ben Macdui.

Am Fear Liath Mòr has been classically described as a supernatural being, rather than a cryptid such as Bigfoot or the Yeti. However, there is an even more interesting and scientifically plausible explanation. Am Fear Liath Mòr is the climber themselves.

As poetic as this sounds – that you are confronted by a gigantic shadow of your inner self at the top of a misty mountain – it is a well-documented phenomenon known as a Brocken spectre.

This happens when the sun is at an angle, shining from behind the observer into mist or fog at the top of a peak. A shadow is cast and appears magnified because of the vast distance between the observer and the fog. Because the background is a fog with little feature, the observer loses their depth perception and see an ill-defined, massive being. The rippling of the water droplets, wind and the observer’s own movements all contribute to the shape appearing alive.

Furthermore, there are many factors that would cause the eeriness commonly reported by people who witness a Brocken spectre. Winds echoing through a pass tend to create very low-frequency sounds that cause uneasiness in people. There is likely a large psychological component as well, as the climbers tend to be alone in a dark mountain, while fatigued from their long climb.

Brocken spectres are a classical example of just how awe-inspiring natural phenomenon can be, especially after understanding the scientific principle behind them.

Meaningful Gift

Posted on by Jinavie

People have been giving gifts to each other since the dawn of time. It is a way we show that we care about someone by giving them something that we think they might like. There are many kinds of gifts, from sharing a snack, a flower from the side of the road, hard cash, a book, an expensive piece of jewellery or a heartfelt letter.

Even though we give and receive so many gifts – such as for birthdays, holidays and anniversaries – choosing the right gift is a difficult job. To give a good gift, you need to know the person’s needs and interests, have decent tastes and be original to some degree. Otherwise, you make the mistake of giving them something that they already have, will never use or find absolutely boring.

So what makes for a good gift? Some people may take the consumerist approach of giving an expensive gift, because it shows the other person how much they are worth to them. To practical people, the best gift may be something that the person needs at that moment, such as a new pencil case or furniture. Some may even say that they would rather give cash so the person can buy what they want instead of you having to guess it.

The problem with the above approaches is that they miss the point of gift-giving. The best gift is a gift that we got for someone because we sincerely wanted to – because we felt that this gift might bring a smile to the person receiving it. Gifts do not hold absolute value; they are not something you should treat like transactions, nor must they fulfil a certain purpose. They hold relative value, in that the value of the gift lies in how the person receiving it feels when they open it up.

For example, cash is useful, but it says nothing about how well you know someone. An expensive necklace is pretty, but anyone with enough money can buy it. If the person is financially stable, they can buy things that they need themselves. A small gift that makes the person feel special and loved is far more valuable than any jewellery.

Here are some alternative types of gifts if you cannot think of a decent gift.

The first are experiences. Money cannot buy happiness, but they can buy experiences that leave everlasting memories, such as a fancy dinner or skydiving.

The second are things that they would be hesitant or not consider buying for themselves, even if they would enjoy them. This may be an experience like above, such as a degustation, or an investment in to their hobby such as a better instrument or accessory.

Lastly, consider giving the gift of time. These are gifts that may not have much financial value, but they hold sentimental value and that require the investment of your own time. Examples include: a scrapbook of your special memories with that person, dedication of practising a performance for the person, or a mix of songs you think the person would enjoy. Because in our busy lives, the scarcest, most valuable resource is our time. By spending our precious free time to create something that celebrates our connection with the recipient of the gift, we can truly show how much we care about that person. It also ticks the box of being original and useful, because each connection is unique and they can be looked back on for nostalgia.

A gift is only as good as how the person feels when they receive it. Instead of showing how much you care through materialism, try showing how well you know them as a person and how much you value the connection that you share. A thoughtless gift is no better than not giving a gift at all.

Voodoo Death

Posted on by Jinavie

We inherently fear death. Much of what we do biologically is struggling against death. We eat and drink to sustain ourselves. We feel pain to avoid things that may eventually kill us. Even moments before our death, our brain will flash our life before our eyes to grasp at any past experiences that may help us survive.

Because of this, we are also inherently neurotic. Some fear flying in a plane because they can imagine the plane crashing and burning, even knowing that flying is safer than a car ride. Childhood traumas where we thought we might die cause long-lasting damage to how we behave and think as an adult.

The most interesting example of how the fear of death can affect us is the phenomenon of voodoo death.

American physiologist Walter Cannon published a paper in 1942 studying cases of “voodoo death” – where healthy people (usually from tribal societies) suddenly passed away after being cursed. Voodoo death starts when a person is cursed or condemned to die by a medical person, such as a witch doctor or shaman. The victim and those around them must believe that the curse will actuall kill them (due to the culture or tradition). The victim’s family may even prepare a funeral. The victim loses all hope that they can survive the curse. They then die, even though their body shows no signs of physical ailment.

For example, the Australian Aborigines are known to have practised “boning”, where a witch doctor would point a vexed bone at an enemy, causing the victim to immediately convulse and die. A Nairobi woman passed away within 24 hours of finding out that the fruit she ate was sacred and she committed a great sin. A Maori man, who was told he should never eat wild game meat, died a day after finding out that he had accidentally eaten wild game meat – even though he had eaten it 2 years ago.

Voodoo death is not only limited to pre-modern societies. In the 1990’s, there was a documented case where a patient was diagnosed with terminal metastatic oesophageal cancer. After saying his goodbyes to his family as were his last wishes, he swiftly passed away. On autopsy, they discovered that the cancer had not actually spread that much and was not the cause of death.

There are many theories as to what may cause voodoo death. The traditional thought was that intense fear and stress stimulates the release of catecholamines such as adrenaline, inducing a massive fight-or-flight response, as seen in broken heart syndrome. The surge of adrenaline causes the heart to beat too fast and too strongly, until it gives out and causes cardiac arrest.

However, more recent studies showed that animals that die from stress exhibit signs of the opposite happening – that is, the parasympathetic nervous system (responsible for the common type of fainting spells called vasovagal syncope) is overactive. Because the parasympathetic nervous system has the opposite effect to the sympathetic (fight-or-flight), it can cause the heart to slow to the point of stopping.

This parasympathetic overactivity may be triggered by a sense of absolute hopelessness, essentially causing the body to “give up” on life. On a related note, the hopeless victim will likely not be eating or drinking much while under extreme emotional duress, so dehydration and catatonia may play a role as well.

Voodoo death is an excellent example of how much power the mind has over the body. Ironically, the fear of death itself can cause death.

The Loneliest Whale

Posted on by Jinavie

In 1989, an array of US Navy hydrophones (underwater microphones) in the North Pacific Ocean discovered a peculiar sound. It sounded very similar to a typical whale song, but there was a crucial difference. Most whales sing at about 10-40Hz, which is a very low frequency sound. However, this specific whale song played at 52Hz – significantly higher than other whale songs.

Bill Watkins was a scientist who became fascinated by this sound. He detected the same sound year after year for over a decade and recognised that it was coming from the same whale. It followed seasonal migration patterns and the song had definite, common features of whale songs. But this song was higher pitch than every other whale he compared it to.

This whale has since been called the “52-hertz whale”, also known as “the world’s loneliest whale”. There have been no other recordings of whale songs like it. There are many theories about what kind of whale it might be, with the leading theory being that it is a hybrid of a blue whale and a fin whale. Because hybrid animals (crossbreeds) have different body morphologies to the parent species, theoretically it could produce a unique sound.

Whales sing to communicate with each other. In the vast ocean, sight becomes easily obscured, but the low-pitched vocalisations of whales can carry on for hundreds of miles. This raises the question of whether the 52-hertz whale’s calls are heard by other whales, given that it is talking in a different frequency range. If they can’t, there is a chance that this whale is calling out into the void, only to be ignored by every other whale. It might have been swimming alone for decades, in search of a partner who can communicate with it.

In some ways, we are all somewhat like the 52-hertz whale. Because we are all unique individuals, even when we talk in the same language, we often misinterpret each other or fail to make a connection because we cannot understand their way of thinking. This is why when you meet someone who thinks on a similar frequency to you, it is a connection worth holding on to. There is no greater thrill than meeting another soul who you can say one thing to and they will understand ten things.

These are the kinds of relationships you should treasure, because for all you know, you may end up like the 52-hertz whale – drifting along the deep blue ocean, desperately calling out in hopes of hearing any kind of reply.
