Typhoid Mary

Posted on by Jinavie

New York City, 1901 – an upper-class family presented with fevers and diarrhoea, diagnosed with the infection typhoid fever. This was unusual as typhoid fever was classically associated with poor hygiene, overcrowding and lower socioeconomic status households. It was atypical to see typhoid fever in upper-class households. Within a year, a lawyer and his household fell ill to the same disease – 7 out of 8 people contracted typhoid. Another case emerged 5 years later in Long Island, New York – an area where typhoid fever was very uncommon. This time, 10 out of 11 family members were hospitalised with typhoid. Countless families fell victim to typhoid fever within this year and people started becoming curious as to the cause of this epidemic.

In 1906, typhoid researcher George Soper began investigating the epidemic and found a common link between all of the families who became sick. They had all at some point employed a cook by the name of Mary Mallon. Soper noticed that Mallon had worked for each of these families roughly three weeks before each of them fell victim to the illness, upon which she would leave the job for another family. Soper approached Mallon to obtain urine and stool samples to prove this, but Mallon adamantly refused and denied any responsibility in her possible role in spreading typhoid as she “was not sick”.

Eventually, the New York City Health Department appointed Dr Sara Josephine Baker to handle the situation. Mallon still refused to comply with the investigation and had to be taken into custody by the police. She was forced to be tested while in prison, which proved that she was an asymptomatic carrier of typhoid fever. Doctors discovered that she had a significant growth of typhoid bacteria in her gallbladder. It was determined that Mallon has infected the families through preparing and serving food (she was famous for her ice cream) with poor hand hygiene.

Due to her non-compliance to the order of restricting her from being a cook, Mallon was quarantined for the rest of her life until she died from a stroke in 1938. Mallon – or as the media called her, “Typhoid Mary” – was the source of at least 51 confirmed typhoid fever cases, three of which were fatal. Some estimates say she could have been responsible for as many as 50 deaths as she had worked under many aliases. All because she did not wash her hands properly.

Twelve Coins

Posted on by Jinavie

Imagine that there are twelve coins in front of you. They are exactly the same size and shape, but one is either lighter or heavier than the other 11. To determine which coin is the odd one out, you are allowed to use a scale exactly three times. How do you find the unique coin while figuring out whether it is heavier or lighter than the other coins?

Salt And Flavour

Posted on by Jinavie

A well-known cooking fact is that salt “brings out the flavour” of foods. This not only applies to meats and vegetables, but also unlikely foods and drinks such as brownies, watermelons, coffee and chocolate milk.

Salt (sodium chloride) will dissolve in water to form sodium and chloride ions. Sodium ions interfere with the way your taste buds sense flavour, suppressing bitterness. This is why adding a dash of salt to coffee and chocolate milk will make it taste fuller and smoother.

Furthermore, the sodium ions enhance flavour by making taste buds more sensitive for other flavours such as sweet, sour and umami (savoury). Lastly, in the case of chocolate milk, the slight salty taste gives a greater contrast for the sweet flavour, making the drink taste slightly sweeter.

Fortune Telling

Posted on by Jinavie

Humanity has always been interested in trying to predict the future. Even if the future cannot be changed, we seem to have a primal craving to know something that should not be known. The history of fortune telling can be traced back to ancient times in almost every culture.

The ancient Greeks were particular fans of divination – the art of foreseeing with the inspiration of a god – and the most famous example is of course the Oracle of Delphi. The priestesses of the Temple of Apollo at Delphi were known to give very accurate, yet cryptic, prophecies inspired by Apollo. For example, when Croesus, king of Lydia, consulted the Oracle regarding his invasion of Persia, he was advised: 

“If you cross the river, a great empire will be destroyed”. 

Croesus believed this to mean that he would conquer Persia, but ultimately, the invasion failed and his own empire was destroyed by the Persians instead.

However, as the Oracle of Delphi would only give prophecies on the 7th day of every month, most commoners could not afford to have their fortunes told by them and would instead turn to seers. Seers told fortune through variable method, all with the purpose of interpreting “signs from the gods”. An example would be a haruspicy – divination through the inspection of an animal’s organs, commonly a sacrificed sheep’s liver.

Divination was an important part of Native American cultures. Diviners would use potent hallucinogens to reach an altered state of mind to derive visions. Scrying was also common – the practice of “seeing” the future by using reflections in mirrors or water surfaces.
In ancient China, oracles would read the future by reading the patterns of cracks on a burnt turtle shell (plastromancy). Nostradamus, the famous French seer, would scry the future in a bowl of water. The most classic, stereotypical image of a fortune teller is a gypsy woman gazing into a crystal ball or reading the palm of a person to foresee an individual’s future.

Fortune telling still plays an important role in the modern world, with a significant proportion of people in multiple cultures believing that the future can be predicted by fortune tellers. In the Western world, horoscopes are a common feature of newspapers and astrologists and tarot card readers are frequented by people seeking advice. In countries such as Korea, China and Japan, a significant number of people will seek fortune tellers to see how “well-matched” a couple are before marriage is decided.

There has been zero scientific evidence to suggest that clairvoyance is real. However, perhaps that is not the point of fortune telling. Another name for fortune tellers is soothsayers – perhaps having our fortune told gives us a sense of comfort as it eases our morbid curiosity for what the future holds. The future is an endless sea of possibilities and the realisation that anything could happen can be crippling. So maybe the aim of fortune telling is not to predict the future, but to temporarily treat your fear of the future so that you may live in the present.

Three Types Of Responses

Posted on by Jinavie

In his book Praise of Escaping (“Éloge de la fuite”), physician Henri Laborit suggests the following. When a person faces an ordeal, they face three options. The first is to fight against the ordeal, the second is to do nothing and third is to flee from it.

Firstly, fighting against a challenge is a very natural behaviour. These people are not hurt by the ordeal because they turn the attack into a retaliation. But this attitude has a problem. Continuous attacks and retaliations result in a vicious cycle. An aggressive person ultimately will be stopped by someone who is stronger than them.

The second option involves not doing anything in the sense that you act as if you hadn’t been attacked by pushing down the resentment. This is the most widely accepted attitude in modern society. Scholars call this behavioural inhibition. People with this attitude have the want to punch their opponent in the face, but swallow their anger as they recognise the risk of being retaliated against and entering a vicious cycle. And so, the punch that did not land on the opponent hits themselves instead. This may even show as medical conditions such as stomach ulcers, aches, or other psychosomatic symptoms.

The third way of escaping can be done through different ways.
Chemical escape: Alcohol, cigarettes, drugs, stimulants, relaxants, sleeping pills. All of these can soften or erase the pain from external attacks. By using these substances to forget everything and knocking oneself out, the ordeal will pass. However, because this kind of escape weakens your sense of reality, people who use this method lose their ability to live in the real world.
Geographical escape: Moving from one place to another endlessly. Some people shift their problems by changing jobs, friends, lovers and the places they live in. It doesn’t necessarily solve the problem, but they feel a little better and gain energy from changing the environment they are in.
Creative escape: Transforming your anger and pain into film, music, writing, painting, sculpting etc. Some people take the things they cannot dare say in the real world and have characters in an imaginary world say it instead. By doing this, they feel a sense of catharsis. People who like to watch characters in movies and books take revenge against those who have wronged them also fit into this category.

Genuine Smile

Posted on by Jinavie

Guillaume Duchenne, the famous French neurologist of the 19th century, conducted many experiments to study facial expressions. Part of his research involved determining how certain expressions are produced – such as stimulating different muscles with electricity to see what muscle produced what expression. During this research, Duchenne identified that a smile could be divided into two distinct groups.

The first – what he called the “Duchenne smile” – involves a muscle called zygomatic major, which raises the corners of the mouth, and also orbicularis oculi, which raises the cheeks and wrinkles the corners of the eyes. The second (“non-Duchenne smile”) type of smile involves less muscles; more specifically it only uses the zygomatic major muscle.

To better visualise this, think of what a natural, genuine smile looks like – a wide grin on the mouth, lifting of the cheeks and slanting of the eyes. This is a Duchenne smile, as opposed to the forced, non-Duchenne smile you see often in photographs. Duchenne concluded that a Duchenne smile only showed when the person was genuinely experiencing a positive emotion. Non-Duchenne smiles were more associated with polite social behaviour when people were pretending to have a good time.

The easiest way to distinguish the two is to look at the eyes, for a real smile is when the eyes are smiling as well. This is a useful physiological trick to remember when you want to figure out whether someone is smiling because they are genuinely happy, or because they are just trying to be polite. Also, knowing how to smile with your eyes to fake a “genuine” smile can be a handy social skill.

Evolution Of Colour

Posted on by Jinavie

We often take the beauty of colour for granted. How would you explain the colour red to a blind person? With that in mind, how do we know that the colour we see with our own eyes is the same hue that others see? A scholar by the name of William Gladstone came across a similar question in 1858 while studying ancient Greek literature. He noticed that in most literature of ancient times, the description of colour was wildly inconsistent, such as the sea being described as “wine-dark”, the sky being “copper-coloured” and other oddities such as violet sheep and green honey. After further analysis, Gladstone found that white and black were referenced frequently, while other colours were much rarer, with red, yellow and green being the most common colours respectively.

Another scholar named Lazarus Geiger expanded on Gladstone’s research and found that throughout ancient literature – including the Bible, Hindu poems, ancient Chinese stories and Norse tales – described beautiful scenes while omitting a certain detail: a blue sky. It appeared that the colour “blue” did not appear in most languages until a certain point in time, despite the people having lived under the same blue sky that we do now.

Geiger tracked the appearance of different colours in different languages and found a pattern of development. Each language would typically describe white (light) and black (dark) first. The next colour to develop was red, then yellow and green, with blue being one of the last colours to appear. This is likely related to the abundance of each colour (e.g. blood, dirt, vegetation) and the ease of making coloured dye (blue dye is notoriously difficult to make).

This raises an interesting question: if the ancient Greeks did not have a word for the colour blue, could they still perceive the colour blue? Biologically speaking, our eyes are not so different to that of the ancient Greeks. But of course vision is a two-part process – your eye captures the image and then your brain processes the image. Does language have a significant enough impact on how we perceive our world?

image

There is a tribe in Namibia whose language does not distinguish blue and green. A study was held where people from this tribe were shown a circle of 12 squares – 11 green and 1 blue. To the researcher’s intrigue, the men and women of the Himba tribe could not tell which square was the odd one out – suggesting that their brain was processing the two colours as identical. However, the Himba language has more words distinguishing shades of green than English. In another study involving a circle of green squares with one square being a slightly different shade of green, the Himba tribe could pick out the different square much more easily than English-speakers.

The so-called “colour debate” is a hotly debated topic, with some arguing that language plays a crucial role in determining our perception of the world, while others state that language is separate to our senses. What did the ancient Greeks see when they gazed up into the sky? If we cannot describe something with words, then does it truly exist? But one thing is clear – things are not always as they seem.

Doing The Opposite

Posted on by Jinavie

Routines make you become more and more rigid in your thinking. At times, doing the complete opposite of what you want to do may be more beneficial. For example, staying awake when you feel sleepy, sitting in silence when you want to listen to music or walking to your destination instead of driving there. These small acts may allow you to discover fresh feelings and new directions.

Six Month Break

Posted on by Jinavie

Imagine if you will, that you could drop whatever is happening in your life and have a six-month break. No matter what you are doing – studying, working, preparing to get married – you are allowed to forget about your life and have six months off. During this time, you may go wherever you want and do whatever one thing you have always dreamed of doing as a profession. 

Whether you want to be a walking tour guide in Europe, a scuba diver in the Caribbean islands or a professional gambler in Las Vegas, you can be it. Furthermore, there are no consequences of your break (i.e. you will return back to your normal life afterwards as if it did not happen) and you do not have to worry about skill levels (i.e. you will be at the perfect skill level for your job before you start).

Now that we have set up the perfect “break”, what will you choose to do with it? This question may seem simple, but it helps you search deep inside you for what you truly want in life. Too often in life, we have to set aside our dreams and aspirations just to survive reality. In such a world, telling people to “do what you love” or “chase your dreams” can sometimes seem ignorant as many people do not have the luxury of doing so.

That being said, there is no harm in dreaming – in imagining a world where things could be different and you could do what you really wanted to do. Even if you couldn’t take six months off to chase your dreams, perhaps there are other ways to live a little happier. If your fantasy was to be a barista in Italy, learn to make coffee using a filter. If you dream of being a rap star, spend five minutes of every day writing down some sweet rhymes on a notebook.

Dreams will make your life happier one way or another. All you have to do is give your dream a chance. So what is your dream break?

The Gift Of Flowers

Posted on by Jinavie

Why do we give flowers to express our love for another person? Handwritten letters take effort and pouring out your heart, while diamonds represent eternity. Flowers on the other hand, are easy to acquire and will eventually wilt away. Of course, that is a rather cynical view. There are numerous reasons why people choose flowers as gifts.

Flowers have a language of their own, so choosing the right flower can mean all the difference for a person who has an interest in flowers. For example, red roses represent true love and passion, lilies represent innocence and purity, while lilacs represent memories of youth and your first love.

It is true that flowers are not permanent things, but they symbolise an aspect of love that is more important than “eternity”.
A flower wilts when it is not cared for. Flowers wilt when they are not given enough water or just left in stale water for days without changing the vase water. Every flower needs different kind of care, for example, an orchid may wilt if left in direct sunlight and should be kept in indirect light.

Relationships are inherently dynamic – if you do not pay enough attention to the other person and constantly care and make an effort, it will slowly wilt until it dries up into bitterness. In that regard, perhaps flowers are a better gift than diamonds to symbolise love, as it is a reminder how true love is not something you expect to always stay the same, but something that you have to work hard to maintain.

Or perhaps there is a simpler reason we give flowers to each other. They are simply beautiful to look at add a fresh aroma to the environment. At the most superficial level, a lovely bouquet of flowers is a pleasant thing to receive. Perhaps beyond all the metaphors and hidden meaning, all we wish to say is: “I want to put a smile on your face”.
