Sudden Death

Unlike diseases such as tuberculosis or cancer, some disease processes are known to kill a human being within an hour of onset. Other than the obvious causes such as decapitation, massive bleeding or any other trauma-related injuries, these diseases tend to be cardiac or respiratory in origin.

A common example is coronary artery disease, where the blood vessel providing blood to an area of the heart becomes completely blocked by stenosis (narrowing, often by atherosclerosis) or a clot. This results in immediate ischaemia (lack of oxygen) to heart muscles, which causes cell death. This produces scar tissue which disrupts the electrical activity of the heart, which may lead to a condition called ventricular fibrillation where the heart beats in an uncontrolled, erratic manner. When in VF, the heart effectively becomes useless as it cannot coordinate proper pumping function. Blood circulation stops and the patient goes in to multiple organ failure (the brain goes first) within a very short time. Although it can kill within a short time, early identification and treatment may be able to prevent VF from occurring and save the patient’s life. If VF does occur, it is crucial to begin CPR or use a defibrillator if available.

VF can also occur in other situations. For example, there is a genetic condition called long QT syndrome which predisposes the patient to spontaneous arrhythmias (electrical abnormalities in the heart). Even becoming too excited can sometimes set off a VF in some LQTS patients, thus they require an implantable cardioverter-defibrillator (ICD) to shock their heart back in to normal rhythm every time they develop an arrhythmia.

Some other causes of sudden death include: aortic dissection (tearing of the aorta that may cause massive internal bleeding), pulmonary embolism (a clot obstructs blood flow in the lung, stopping circulation), commotio cordis (a blow to the heart at a certain moment in the heart rhythm triggers VF), ruptured brain aneurysm (ballooning of an artery in the brain), anaphylaxis (severe allergic reaction that cuts off airflow to the lungs) and poisoning (various mechanisms, mainly related to disrupting cellular function).

Death can strike swiftly, even from within your body.

Apple

Apples are strewn throughout history and mythology, acting as a key component of human societies. Its symbolism ranges from the sin of Adam and Eve to the love of Aphrodite. Let us look at some apples that have made a significant impact in the world – real or mythical.

Apple of Temptation: According to the bible, Eve is tempted by the snake to take the forbidden fruit from the Tree of Knowledge. By taking from the tree and eating this fruit (then sharing it with Adam), the two are banished from the Garden of Eden and humanity is cursed to live in the harsh world and for women to suffer the pain of childbirth. Although the bible never defines the forbidden fruit as an apple, artistic depictions during the Renaissance has solidified the idea. The eponymous Adam’s apple (the lump on men’s necks) is said to be a piece of the apple being stuck in Adam’s throat.

Apple of Discord: According to Greek mythology, Eris (goddess of discord) threw a golden apple into a wedding after not being invited to it. The apple was inscribed with the message: “For the fairest one” and Hera, Athena and Aphrodite all claimed the apple was for them. Eventually, the judgement was delegated to Paris, prince of Troy. Each goddess bribed him with power, strength and love respectively but Paris eventually chose Aphrodite and in return, received the most beautiful woman in the world – Helen of Sparta. This sparked the great Trojan War, resulting in the destruction of Troy by the Greek alliance.

Apple of Love: Atalanta (Greek mythology) was a beautiful woman who had sworn virginity to the goddess Artemis. To avoid marriage, she challenged suitors to a footrace and only the winner would take her hand in marriage (the rest were killed). A man named Hippomenes went to Aphrodite’s temple to seek advice and was given three golden apples. He used the apples to distract Atalanta during the race by tossing it near her. This allowed him to win the race and ultimately took Atalanta’s hand in marriage. This story also shows how the ancient Greeks saw apples as a symbol of love, as evidenced by the gesture of one throwing an apple to the person they are in love with. Catching the apple was accepted as a sign of reciprocity.

Apple of Challenge: One of Hercules’ twelve challenges was to take the Golden Apples of Hesperides, protected by Ladon, a dragon with a hundred heads. Hercules bargained with Atlas to hold the Earth while he retrieved it. Atlas tried to walk away free from his damned task, but Hercules tricked him by asking to hold the Earth while he shifted his cloak.

Apple of Death: In the fairy tale, Snow White, the evil queen uses a poisonous apple to murder Snow White. The symbolism of the apple is similar to the biblical story mentioned above. Despite the dwarves warning her about stranger danger, Snow White takes the gift of a stranger without enough caution and suffers the consequences. However, she is resurrected by the kiss of the prince. Perhaps Aphrodite’s apple of love counters the evil apple of death and sin.

Apple of Revolution: A famous Swiss folklore describes how William Tell had to shoot an apple from his son’s head with his crossbow as punishment for not submitting to the occupying Austrians’ leader, Gessler. Being an expert marksman, he successfully hit his target instead of killing his son. When he was questioned why he drew two bolts from his quiver, Tell replied that he was aiming to shoot Gessler if he accidentally killed his son. This infuriated Gessler, who arrested William Tell. However, Tell escaped and went on to lead the revolution against the oppressors, aiding in the liberation of Switzerland (according to the legend).

Apple of Philosophy: There is a record of a young Martin Luther (who founded the protestant church) writing in his diary: “Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree”. The philosophy behind this saying is not that gardening is important. Here, Luther is saying that we should live every day as if it is the last day. Live without regrets. Besides, would we not look silly if the world did not end and we had wasted a day panicking and doing absolutely nothing productive?

Apple of Knowledge: The story of how Isaac Newton devised the theory of gravity after being hit on the head with an apple is a famous story. Although the “hitting on the head” part is dubious, evidence suggests that he used apples falling from a tree as an example of how gravity works. Although the concept of gravity was already established, Newton focussed on how apples always fell perpendicular to the ground and deduced that objects have a gravitational pull on other objects (as the Earth pulls the apple and vice versa). He extrapolated from the apple to discover how Earth’s gravitational field controls the orbit of the Moon. Thus, it can be said that apples played a “crucial” role in the advancement of modern physics (although Newton probably did not need the apples for his theory).

Apple of Innovation: In 1976, Steve Jobs co-founded Apple Inc. to develop the first personal computer. The company would go on to revolutionise mainstream digital technology by coming up with innovative products such as the iPod. Steve Jobs was the face of this new wave of innovation; with his bold outlook on the future and powerful leadership he made Apple Inc. one of the most successful companies in the 21st century. Jobs successfully popularised many pieces of technology, such as personal computers, portable music players and tablet PCs. Interestingly, he came up with the logo and name of the company after seeing a cartoon of Newton and his apple. Perhaps Jobs was seeking to create a company that would be one of the many “apples” that were turning points in history.

Zombie

Clairvius Narcisse died in Haiti on May 2, 1962. In 1980, he returned to his hometown. Alive.
How did a man who was dead and buried come back to life?

According to Clairvius, he was cursed by a bokor (sorcerer) to become a zombie but returned home after the curse was undone. The sorcerer had enslaved him in a sugar plantation for 16 years and many others were working as “zombie slaves” until they revolted, killed the sorcerer then ran away.
Harvard ethnobotanist Wade Davis studied and investigated this case extensively. According to his research, most “zombies” were placed in suspended animation to fake death and were then (often after being buried) put under psychosis by the sorcerer. Many Haitians believe in the ancient African religion of voodoo, where one legend says that when a sorcerer curses a person, they are revived after death to become the sorcerer’s slave. Thus, Haitians strongly believe in the legend of zombies. In reality, the sorcerer was using drugs to zombify people and Davis used his expert knowledge in botany to deduce what the chemicals were.

The so-called zombie powder was a combination of tetrodotoxin (TTX, blowfish poison) and datura (from the poisonous plant Datura stramonium). The TTX simulates death due to its paralytic effect and datura is a powerful hallucinogenic that causes the person to confuse reality and fantasy (dissociation). Also, it may cause memory loss which allows the sorcerer to easily manipulate the victim. Long-term maintenance of the datura dose could allow the sorcerer to enslave someone for a long period of time. However, the zombification is not the same as perfect mind control and more like a strong hallucination or hypnosis (as seen as the above mentioned revolution).

As it involves the handling of poisons, only an experienced sorcerer could give the right mixture of doses while avoiding the lethal dose. Although science has advanced greatly, there are still many things we can learn from magic and sorcery. The reason being, magic and sorcery are simply undiscovered science.

Bleach

The most potent and frequently used household cleaning product is bleach. Bleach is a diluted solution of sodium hypochlorite (NaClO), which has powerful antimicrobial properties thanks to the element chlorine. This is also the reason chlorine is used to treat tap water and disinfect pools.

Although it is an extremely useful chemical, chlorine also has a very dark side. Chlorine gas is a highly toxic gas, which forms hydrochloric acid when breathed in and seriously burns the respiratory tract. Due to its toxicity, chlorine gas was used as a weapon of mass destruction in World War I. However, this terrifying gas can be made very simply at home. Unfortunately, this is often done accidentally (but sometimes on purpose) and causes significant damage.

The key warning for using bleach is that it must never be mixed with other cleaning products. If mixed with an acid cleaner, it causes a chemical reaction that produces chlorine gas, while mixing it with ammonia creates chloramine, another deadly gas (although dangerous in itself, chloramine can sublimate into chlorine gas too). Therefore, many people suffer a loss of smell, consciousness or their lives by accidentally mixing two cleaning products or cleaning up urine with bleach. A major problem is that these victims tend to be children who unknowingly mix the chemicals, creating a horrible accident. What is more unfortunate is that some people choose to end their lives using this method.
If you do find a person rendered unconscious by chlorine, it is imperative to quickly move them to a well-ventilated area, while not endangering yourself. An ambulance should be called right away.

As seen from above, simple chemicals found easily at home can produce toxic gases, which can cause irreversible damage. Thus, one must never mix bleach and cleaning products and should educate their children on the dangers of chlorine gas.

Shrew

A shrew is a small rodent, similar in size to a rat, that has many fascinating characteristics.

Funnily enough, this animal has a notorious name in history. Ancient Egyptians considered shrews the spirits of darkness and the English believed that if a shrew ran over a lying animal, the animal would suffer great pain. The name shrew comes from the Middle Age English word shrewe, which meant “evil” or “scolding person”.
This is probably attributable to the putrid smell a shrew makes when threatened, and its poisonous bite.

Despite its tiny figure, the shrew has the greatest surface-area-to-weight ratio out of any mammal on the face of the Earth. Because of this, they also have a high heat expenditure, meaning they have to eat constantly to replenish the energy. This means that they sometimes die from starvation during prolonged naps.
Also, they have an extremely high heart rate, averaging about 700 beats per minute. When they are frightened, the heart rate can spike leading to cardiac arrest. For example, shrews are known to die from being frightened by the sound of thunder.

An animal that dies if it naps too much or when thunder strikes – the shrew is a very sad animal.

Get Psyched Mix

The Get Psyched Mix is a list of 24 English rock & roll songs carefully handpicked by Barney Stinson. His intention was to create a mixed CD that steps up from the traditional rule that a mix CD must “rise and fall”; instead, it is all rise. This means that the mix allows for maximum psychitude with no time wasted, giving you that amped feeling to clear away all the worries and troubles of your life.
After listening through the entire mix, you will indubitably feel the need to high five or fist bump your bro and appreciate the beauty of life. Whenever you are down, the Get Psyched Mix will cheer you up without failure.

Madness

“As mad as a hatter” – this is a well-known English idiom, particularly famous after Lewis Carroll created the Mad Hatter character in his work Alice in Wonderland. However, what is less known is the fact that this idiom is based on actual events.

In the 18th and 19th centuries, hatters used mercury to treat felt (traditionally made from rabbit fur or the more luxurious beaver fur). Unfortunately, mercury is a highly toxic heavy metal, which causes severe damage in the human body. In the case of mercury poisoning (also known as Minamata disease or the Mad Hatter disease), it infiltrates neurons to cause severe neurological symptoms. For example, it can impair vision and hearing, cause paresthesia (pins and needles), anxiety, depression, tremors and hallucinations. The famous physicist, Isaac Newton, also suffered from Mad Hatter disease.

Another mad character from Alice in Wonderland is the March Hare. As one may deduce from his name, he is modelled after a normal hare. The reason why the March Hare is mad is that March is around the time when rabbits enter their mating season, and male hares are in heat. They then have only one thing in mind: sex. 

Maybe, as the Cheshire Cat explains, “we’re all mad down here”.

Schroedinger’s Cat

In 1935, Erwin Schrödinger, a famous quantum physicist, devised a thought experiment in an attempt to explain the Copenhagen interpretation of quantum physics (which posits that the state of every particle can be described by a wave function, and that the process of calculating its position determines it). It goes as follows:

A cat is placed in a box with a sealed vial of poison that is set to release when a radioactive material has decayed. As the time taken for the decay varies (roughly 50:50 chance), it is unknown whether the vial has broken after an hour if the box is closed. This also means that it is unknown whether the cat is alive or dead. To solidify this variable reality, one must open the box, whence the cat is determined as either alive or dead. 

This experiment may be hard to understand for a non-physicist, but it is still a fascinating thought experiment. This is because there are many times in life where one cannot know the outcome of something unless action is taken. Ergo, if you want a state of uncertainty, do nothing; if you want a set answer, take action. This is a particularly useful answer to someone questioning whether they should start a relationship with someone and are unsure of the outcome.
