It is said that laughter is infectious. In 1962, an extreme case of “laughter infection” happened in village in Tanzania. The phenomenon originated in a boarding school for girls. On January 30, three girls spontaneously burst out in laughter and could not stop themselves from laughing. Soon after, the whole class was suffering from fits of uncontrollable laughter. The “infection” then spread throughout the school, claiming 95 of the 159 students over a stretch of two months. This strange symptom of uncontrollable laughter lasted anywhere from a few hours to 16 days. Interestingly, teachers were not affected and only girls between the ages of 12 to 18 were affected. By March 18, the school was forced to close down due to students not being able to focus during class.
The laughter epidemic was not localised to the school. After the school shut down and the girls returned home, fellow villagers were afflicted by the laughing disease, resulting in 217 villagers being “infected” by May (mostly children and teenagers). By June, the laughing epidemic spread to another nearby school, affecting 48 girls. The epidemic then went on to claim two more schools, forcing them to close down. By the time the epidemic died down (6 to 18 months after “patient zero”), it had affected over a 1000 people and shut down 14 schools.
So what was this strange disease? Was it some new viral infection causing neurological symptoms? Was it a toxin in the water supply? The answer was even simpler: mass psychogenic illness, also known as mass hysteria. Mass hysteria is a psychological phenomenon that occurs in groups placed in high-tension situations, such as within an airplane. This setting is perfect for triggering a mass delusion, causing the person to believe they are suffering from a physical disease. The trigger is usually another “patient” and the hysteria spreads like wildfire, usually by people seeing affected victims. Although the above case makes mass hysteria look like a harmless, amusing phenomenon, psychosomatism (when the mind tricks the body into thinking it is sick) can cause symptoms such rashes, fevers, vomiting and even paralysis. In fact, all of these symptoms were also reported during the Tanganyika laughter epidemic.
Phones, golf clubs, scissors, forks and knives, the order of writing… Almost everything in this world is made for the convenience of right-handed people. Because of this, there is a hypothesis that left-handed people have a relatively shorter life expectancy compared to right-handed people.
Dr. Diane F. Halpern of California State University conducted a research comparing the life expectancy of right-handed people versus left-handed people. The results were astounding; the mean life expectancy of right-handed people was 75, while left-handed people only lived 66 years on average. Dr. Halpern posited that this was due to left-handed people becoming stressed living in a right-handed world, shortening their life expectancy. Of course, there were debates about whether the results were reliable or not and there was heavy opposition from the left-handed community. But if the left-handed people are enraged about being discriminated against by society, this would stress them out and actually shorten their life, so it might not be best not to debate about the issue.
Left-handedness has historically been associated with evil. The word right also means “good”, while left-handedness is formally known as sinistrality, which shares its etymological origin with sinister. The word for right is associated with good things throughout the world, while left is associated with bad things. In Korea, 오른 (oreun, right) has the same pronunciation as 옳은 (orlheun, true)“. The Chinese character for left (左) is also used to mean “improper”. In medieval Europe, left-handed people were thought to be associated with the devil or witches and were often executed. Left-handed people have been unjustly hated throughout time and space.
Sagittarius is the Zodiac sign for those born between November 22 and December 21. The symbol for Sagittarius is centaur (half-man, half-horse) with a bow and arrow.
The model for Sagittarius is the wisest and most intelligent centaur, Chiron. Although most centaurs are known to be aggressive beasts only interested in women and alcohol, Chiron was different in that he was culture and civilised. He was interested in gathering knowledge and learning philosophy, especially medical knowledge. Chiron is also famous for being the teacher and master of many famous heroes and gods. Among his students are: the god of medicine, Asclepius; the Trojan War hero, Achilles; leader of the Argonauts, Jason; and the famous hero, Hercules. One day, Hercules ended up in a fight with some centaurs, which resulted in a bloody battle. Hercules used arrows coated with the poison of the Hydra (which he obtained during his twelve labours), swiftly killing many centaurs. Chiron saw this battle and galloped there to try and stop everyone from hurting each other. But Hercules did not see his master and accidentally shot him with a poison arrow. Although Chiron was given the gift of immortality by the gods, the Hydra’s poison still caused excruciating pain. Even though he was one of the best medical professions of his time, he could not alleviate the pain and begged Zeus to put him out of his misery. Zeus accepted this and raised him into the heavens to become a constellation as a sign of respect.
The practice of wearing jewellery to signify the sacred bonds of marriage dates back to ancient Egypt, where chains and bracelets were worn. This eventually evolved into wearing a ring, where the circle symbolised endless love while the open centre represented the doorway to an unknown future. This practice spread to the ancient Greeks, then the ancient Romans, where it became a commonplace tradition around the 2nd century. The Romans called the wedding ring annulus pronubis and it was tradition for a man to give a ring to a woman at the betrothal ceremony to symbolise his eternal devotion.
A wedding ring is most often worn on the fourth finger of the left hand, so-called the “ring finger”. It is uncertain when this tradition arose, as various cultures chose different fingers on different hands for the wedding ring. One theory suggests that the tradition arose from the ancient Romans believing that the fourth finger contained a vein called the vena amoris – a vein that connects directly from the finger to the heart. As the heart is a symbol of love, placing a ring on this finger symbolised eternal love. However, this is a false belief for two reasons. Firstly, every vein, by definition, returns to the heart. Thus, it makes no sense that the fourth finger is special. Secondly, there is no such thing as the vena amoris, with all the veins in each finger having an identical structure (common palmar digital veins). As the circulatory system was not known during ancient times, it is likely that this story is a myth that arose sometime after the Middle Ages when a romantic story was matched with the tradition. It is also likely that jewellery companies marketed such a story to promote wedding ring sales (much like the marketing of the diamond engagement rings).
In the New Testament of the Bible, there is a scene where Jesus resurrects a man by the name of Lazarus back four days after his death. This “miracle” is of course a fictitious event, but nonetheless, the name Lazarus has come to symbolise resurrection after death. For example, there are two actual medical conditions named after Lazarus, both related to death.
The first is called Lazarus phenomenon, where a person who is declared to be clinically dead spontaneously returns to life. This is an extremely rare event that has only been recorded in about 30 cases. In most of these cases, the patients had suffered a cardiac arrest, with all attempts at resuscitation (e.g. CPR, adrenaline) had failed. Sometime after the person was declared clinically dead (usually around 5~10 minutes), the person’s circulatory system would suddenly start on its own and the person would be “resurrected” (quite literally). In one case, a 61 year-old woman was declared officially dead after her heart stopped and her vitals did not return after continuous resuscitation. At the morgue, however, she was found to have a pulse and breathing on her own. She later sued the hospital for the neurological and physical injury caused by oxygen deprivation during her death. There is even a case report of a patient who returned to life two and a half hours after dying (although he died again 3 weeks later).
Of course, the Lazarus phenomenon is not a miracle. In most cases, it is hypothesised that when resuscitation is attempted then stopped, there is a rare chance of the relieving of pressure causing blood to fill the heart, causing a sudden expansion and kickstarting the electrical circuit. Other factors that may influence this is hyperkalaemia resulting from ischaemia and high doses of adrenaline given to the patient during resuscitation having a delayed effect.
Because of this rare “complication” of death, doctors are advised to observe the patient for about 10 minutes after declaring them dead. Just in case.
The second is called Lazarus sign and it occurs not in dead patients, but brain-dead patients. Brain-dead patients are immobile as their higher functions such as cognition and motor functions are destroyed. However, there are rare cases where the brainstem is somehow stimulated, triggering a reflex arc from the spinal cord. This reflex is seen as the patient suddenly raising their arms and dropping them on their chest in a crossed position, much like Egyptian mummies. As the spinal cord is not usually damaged in brain-dead patients, this reflex arc is possible, similar to a knee jerk reflex. The Lazarus sign should not be misinterpreted as a sign that a brain-dead patient is conscious, as it is an involuntary movement. However, it has been mistaken for the resuscitation of a patient, or in some cases, as a miracle.
Travelling is fun. But strangely, the etymology of the word travel is the Latin word tripalium, which means “torture instrument”. This is most likely because in the old days before airplanes and trains were invented, travelling was often long, arduous and painful. Travelling is probably the least terrifying form of torture. Let us explore the various methods of torture used throughout human history. There are many types of tortures, but they can be largely divided into physical and psychological torture. The main goal of torture is to induce maximum pain to extract information from, punish or to execute a person.
Physical torture is very simple: inflict as much pain as you can. For example, you can simply tie the person to a chair and beat them senselessly, or apply pressure to a wound to cause intense pain. A useful tip for beating someone is to place a phonebook on their stomach or hand and hitting the book, which transfers pains while not leaving a bruise or any marks. A simple way to cause extreme pain is the use of fingers. Finger tips are extremely sensitive and contain many nerve endings, meaning sticking needles under the nail bed or ripping the fingernails off causes extreme pain. Like this, medical knowledge has often been used to develop new ways to torture people. For instance, heating the sole of the feet with fire causes severe pain, electricity used in the right amount can keep the person alive while causing pain and seizures, and if you lie a person flat and on a slight decline (so the head is lower than the body), put a cloth over their face and pour over it, you can induce a sensation of drowning (this is called waterboarding and is used by the CIA). Another simple, effective torture method is the joori-teulgi(주리 틀기) from Korea, where a person is tied to a chair with the feet bound, with two long sticks inserted between the thighs, crossed, then pulled down to streth the thighs apart. This causes extreme pain and suffering.
As mentioned above, torture can be used to kill a person too. The famous hanged, drawn and quartered torture was used in the Middle Ages to punish treasonists. The convict was drawn behind a horse for a while and then hanged until just before death, when they were disembowelled, beheaded and quartered. Another strange, complicated method of torture can be found in China, where slow slicing was used. Slow slicing involves tying a convict to a post and cutting slices of flesh off him until he dies. Executioners often had an art of slicing in such a way to prolong the suffering for as long as possible without killing the person. Another execution method found in both Western and Eastern history is dismemberment by horses, where the person’s four limbs and head are tied to individual horses (or cows), which are then made to run in different directions to violently rip the person up.
Animals were used in various forms of torture throughout history around the world. Tying the prisoner to an elephant’s feet to crush them to death, putting a rat on the person’s stomach then putting a pot over it and heating it with fire to make the rat burrow into the person’s guts, feeding them to lions or vicious dogs, coating them in honey and leaving them in the path of fire ants to make them get slowly eaten… Out of all of these, the most bizarre method is the goat torture used in ancient Rome. This torture involved tying the prisoner to a chair and securing their feet, which were coated with salt water. Next, goats were released around the prisoner. The goats would lick the sole of the feet to cause tickling, which over a prolonged period is interpreted as pain by the body. This eventually drives the person insane from pain.
Unlike physical torture, psychological torture induces shame and fear rather than pain. Threatening, solitary confinement, sleep deprivation, rape and sexual torture, sensory deprivation, exploitation of phobias, loud noises (such as banging on a door constantly), blindfolding the person and rubbing a balloon on their cheeks, placing foreign objects or snakes in the anus or vagina, leaving them in a container full of insects… Psychological torture has just as much a variety as physical torture and can have longer lasting effects on the person. Furthermore, as it leaves no external marks, it is still frequently used in the modern day.
No matter what the method, inducing extreme pain to control people, extract information and cause suffering is an inhumane act that cannot be tolerated. If mankind had focussed their creativity and effort into more constructive and altruistic things rather than discovering various ways to cause pain, we would probably be living in a much better world.
In the children’s story Goldilocks and the Three Bears, the protagonist is found trying out various porridges, chairs and beds until she finds the one that is just right for her. Because of this, the name “Goldilocks” has become a symbol for something that is “just right”. A Goldilocks economy is one where there is high growth but no inflation; a Goldilocks planet is one which is not too hot or too cold, making it an ideal planet for life; the Goldilocks effect is when success is achieved because something was not too great or too little.
The Goldilocks effect is a law of nature that is far more important than you would think. Nature always seeks consistency, as shown in the human body. For something as complex as life to exist, a cell must maintain its internal environment in a perfect, ideal state. French physiologist Claude Bernard observed that a cell’s internal environment does not change even with changes in the external environment, and commented that “The stability of the internal environment is the condition for the free and independent life”. This is the basis for homeostasis. Without homeostasis, life cannot exist and all living things put in all their effort in keeping homeostasis. Our body constantly strives to keep various factors such as pulse, blood pressure, oxygen saturation, temperature, blood glucose, electrolytes and numerous hormones etcetera in a stable range. One could possibly argue that the meaning of life is “to maintain homeostasis” – a rather cyclical argument.
To understand the importance of homeostasis, let us look at how changes in the external environment affect us. Our core temperature is maintained in a tight range around 36.5 degrees. If it is altered even a couple of degrees, we exhibit symptoms of hypothermia or hyperthermia. If the weather is too hot, we sweat to cool ourselves; if the weather is too cold, we shiver to raise our temperature. After a meal, we secrete insulin to lower our blood glucose, while we secrete glucagon when starving to raise our blood glucose. Failure of either system leads to either diabetes or hypoglycaemic shock respectively. Homeostasis is an extremely complicated and intricate self-repair system that cannot be imitated.
The Goldilocks effect can be applied beyond physiology to our lives. Everything in moderation; to go beyond is as wrong as to fall short. If we have too little money, it is a problem. If we have too much money, it causes other problems. Whether we work or play, doing too much or too little of either can be bad for us. Medicines become poison in excess and even love in excess becomes obsession. In the marathon that is life, if you run too fast you end up collapsing from exhaustion, while running too slow will mean you never get anywhere.
The secret to happiness lies in understanding what is “just right”.
We laugh when we are happy. Laughter provides us with happiness and is the best medicine available to us, relieving the pain and stress of life. In fact, when we laugh we secrete a neurotransmitter called endorphin, which as the name suggests (endo(inside) + morphine), has the same properties as morphine.
What makes us laugh? The best theory to date is that laughter is an instinctive response to the passing of danger (also called the relief theory). For example, if our ancestor came across a predator but it passed by without noticing him, he would have laughed in response to the relief he felt. Others would see from his laugh that the danger had passed and laugh also (possibly explaining why laughter is contagious).
This theory also explains why humour makes us laugh. When you throw a joke, you are essentially giving the other person a “cognitive riddle” with a logical inconsistency. This inconsistency causes the recipient’s subconscious to become confused: “Why is it funny? Why can’t I understand it?”. As jokes are fundamentally a “surprise” to the other person’s mind, they try to solve it and figure it out whether it is a danger or not. If they get the joke, the inconsistency is solved and the person feels relief (as it has been revealed that the confusion brought on by the inconsistency was not dangerous). Once the confusion passes, the person laughs in response. But if the person does not get the joke, the “danger” has not passed and the person does not laugh. This is the basis of one of the laws of comedians: “if the audience is confused, they do not laugh”.
Laughter is beneficial for your health. Frequent laughter lowers the blood pressure, boosts the immune system, relieves pain and lowers the levels of stress hormones such as cortisol. Laughter is especially good for your mental health, therefore having a five-minute laughter yoga session every day where you just laugh as hard as you can will help you lead a happier life. However, ironically laughter can kill you too. Cases of “death from laughter” have been recorded since ancient Greek times to the modern day. The cause has not been identified but it is known that intense laughter can cause cataplexy, which is a paralysis induced by extreme emotions. It is possible that intense laughter overloads the nervous system and causes a heart attack.
When and what was the first surgery performed by mankind? Many would believe it to be a simple procedure such as suturing a wound. But would you believe that the earliest surgical procedure was brain surgery in 6500BC? Surprisingly, this is true.
Archaeologists have found a large amount of skulls with a large, round hole in them. Some of the oldest skulls with holes were found in France, where 40 skulls from the Neolithic era were excavated. Archaeologists believed these holes to be from a battle leading to a dent in the skull. However, these holes were actually the results of a surgery (signs of bone recovery can be seen around the edges of the hole, suggesting the patients were alive for some time even after the operation). These skulls all belonged to trepanation patients.
Trepanation is the surgical opening of the skull by drilling a hole in it. This is an ancient surgery that can be found throughout history. Hippocrates and Galen from ancient Greece both recorded detailed instructions on trepanation, ancient Incans performed the surgery and it was also common during the Middle Ages and the Renaissance in Europe. These surgeries were most likely indicated for skull fractures where fragments were embedded in the brain. During the Middle Ages when it was better known that the brain was the seat of the soul, trepanation was used for psychiatric treatments too. For example, in 15th century Netherlands, trepanation was used to excise a so-called stone of madness that was supposedly the cause of insanity. Like this, it was believed that trepanation could release the demons and insanity trapped in the skull.
Although this operation sounds hilariously misled, it is still used in modern medicine. Of course, it is not known to treat insanity, but rather to treat brain bleeds. Extradural and subdural haemorrhages occur when a rupture of an artery in the brain causes a collection of blood in the skull, compressing the brain. This is a dangerous situation which can lead to a stroke or even death. One treatment of this condition is trepanation, or a burr hole, where a small hole is drilled in the skull to relieve the pressure, lowering intracranial pressure and stabilising the patient. Trepanation is an excellent example of how we can learn from the past and how medical knowledge from ancient times is sometimes still valid.
This world endlessly tells us to live for the desires and wants of others. We live every day to fulfil the desire of our parents, our teachers, our friends and our lovers. But to live for other people’s desired, you must first fulfil your own desires. For our weak “self” identity to survive and develop, we cannot allow other people’s desires dominate us.
There is a mental illness called delusional disorder where the patient is obsessed about a “false belief” and is completely convinced that it is the truth. The word “delusion” brings to mind strange cases such as “I was abducted by aliens” and “the government is monitoring my phone calls”, but these delusions are more common with conditions such as schizophrenia. Instead, delusional disorder presents with delusions such as Othello syndrome (believing your spouse is having an affair) or hypochondria that are not too strange and allows for a relatively normal day-to-day life, making delusional disorder very hard to detect. Furthermore, the patients form these delusions in a very logical and highly structured manner, causing the patient to become easily obsessed with it and make the delusions more believable.
Delusional disorder can be categorised into six types:
Erotomanic type: delusion that someone is in love with you
Grandiose type: delusion that you are godlike and possess greater value, strength, intelligence or identity than others
Jealous type: delusion that your lover is unfaithful
Persecutory type: delusion that someone is acting malevolently or trying to harm you
Somatic type: delusion that you have a medical condition or physical defect
Mixed type: delusion showing characteristics of more than one of the above types, with no one type being prominent
As these patients are so attached to their delusions, treatment is extremely difficult. As soon as a psychiatrist or psychologist attempts treatment or even a close friend denies the delusion, they instantly become an “enemy”. The patient automatically incorporates those people into their delusion and antagonise them to worsen the situation. This is why the key principle of treating delusion is “do not touch the delusion”. For example, if the patient believes they are someone else, instead of negating that delusion you should give them a chance to be that person. A treatment called “psychodrama” uses impromptu acting to bypass the delusion and tries to reach the patient’s subconscious, or their “self”. Through this, one can approach the patient’s “self” via affirming their delusions, allowing the psychiatrist or psychologist to ask what the patient’s “self” wants and discover the source of the delusion. The important point is that this treatment is not an instant cure for the delusions (it takes a while for the patient to rid themselves of the delusions completely).
Delusional disorder is a phenomenon which is not uncommon in people who live for the desires of others. A perfect example would be young celebrities. If young teenagers begin life in the entertainment sector and live for the audience before they develop their own “self”, they may not be able to find answers to questions such as “who am I” and “what do I want”, ultimately causing a weakening of their identity. As the “self” is highly capable of tricking itself, it creates a delusion that can rationalise this situation and works to create a different identity.
Thus, the most important tool for surviving in this world is not money, power, wisdom or love: it is your identity and “self”. If you do not know what you truly want, then life cannot give you happiness and success.
