Sooner or later we all face death. Will a sense of meaning help us?
As a doctor, I am reminded every day of the fragility of the human body, how closely mortality lurks just around the corner.
'Despite all our medical advances,' my friend Jason used to quip, 'the mortality rate has remained constant – one per person.'
Jason and I studied medicine together back in the 1980s. Along with everyone else in our course, we spent six long years memorising everything that could go wrong with the human body. We diligently worked our way through a textbook called Pathologic Basis of Disease that described, in detail, every single ailment that could befall a human being. It's no wonder medical students become hypochondriacal, attributing sinister causes to any lump, bump or rash they find on their own person.
Jason's oft-repeated observation reminded me that death (and disease) are unavoidable aspects of life. It sometimes seems, though, that we've developed a delusional denial of this in the West. We pour billions into prolonging life with increasingly expensive medical and surgical interventions, most of them employed in our final, decrepit years. From a big-picture perspective, this seems a futile waste of our precious health-dollars.
Don't get me wrong. If I get struck down with cancer, heart disease or any of the myriad life-threatening ailments I learnt about in medicine, I want all the futile and expensive treatments I can get my hands on. I value my life. In fact, like most humans, I value staying alive above pretty much everything else. But also, like most, I tend to not really value my life unless I'm faced with the imminent possibility of it being taken away from me.
Another old friend of mine, Ross, was studying philosophy while I studied medicine. At the time, he wrote an essay called 'Death the Teacher' that had a profound effect on me. It argued that the best thing we could do to appreciate life was to keep the inevitability of our death always at the forefront of our minds.
When the Australian palliative care nurse Bronnie Ware interviewed scores of people in the last 12 weeks of their lives, she asked them their greatest regrets. The most frequent, published in her book The Top Five Regrets of the Dying (2011), were:
- I wish I'd had the courage to live a life true to myself, not the life others expected of me;
- I wish I hadn't worked so hard;
- I wish I'd had the courage to express my feelings;
- I wish I had stayed in touch with my friends; and
- I wish that I had let myself be happier.
The relationship between death-awareness and leading a fulfilling life was a central concern of the German philosopher Martin Heidegger, whose work inspired Jean-Paul Sartre and other existentialist thinkers. Heidegger lamented that too many people wasted their lives running with the 'herd' rather than being true to themselves. But Heidegger actually struggled to live up to his own ideals; in 1933, he joined the Nazi Party, hoping it would advance his career.
Despite his shortcomings as a man, Heidegger's ideas would go on to influence a wide range of philosophers, artists, theologians and other thinkers. Heidegger believed that Aristotle's notion of Being – which had run as a thread through Western thinking for more than 2,000 years, and been instrumental in the development of scientific thinking – was flawed at a most fundamental level. Whereas Aristotle saw all of existence, including human beings, as things we could classify and analyse to increase our understanding of the world, in Being and Time (1927) Heidegger argued that, before we start classifying Being, we should first ask the question: 'Who or what is doing all this questioning?'
Heidegger pointed out that we who are asking questions about Being are qualitatively different to the rest of existence: the rocks, oceans, trees, birds and insects that we are asking about. He invented a special word for this Being that asks, looks and cares. He called it Dasein, which loosely translates as 'being there'. He coined the term Dasein because he believed that we had become immune to words such as 'person', 'human' and 'human being', losing our sense of wonder about our own consciousness.
Heidegger's philosophy remains attractive to many today who see how science struggles to explain the experience of being a moral, caring person aware that his precious, mysterious, beautiful life will, one day, come to an end. According to Heidegger, this awareness of our own inevitable demise makes us, unlike the rocks and trees, hunger to make our life worthwhile, to give it meaning, purpose and value.
While Western medical science, which is based on Aristotelian thinking, sees the human body as a material thing that can be understood by examining it and breaking it down to its constituent parts like any other piece of matter, Heidegger's ontology puts human experience at the centre of our understanding of the world.
Ten years ago, I was diagnosed with melanoma. As a doctor, I knew how aggressive and rapidly fatal this cancer could be. Fortunately for me, the surgery seemed to achieve a cure (touch wood). But I was also fortunate in another sense. I became aware, in a way I never had before, that I was going to die – if not from melanoma, then from something else, eventually. I have been much happier since then. For me, this realisation, this acceptance, this awareness that I am going to die is at least as important to my wellbeing as all the advances of medicine, because it reminds me to live my life to the full every day. I don't want to experience the regret that Ware heard about more than any other, of not living 'a life true to myself'.
Most Eastern philosophical traditions appreciate the importance of death-awareness for a well-lived life. The Tibetan Book of the Dead, for example, is a central text of Tibetan culture. The Tibetans spend a lot of time living with death, if that isn't an oxymoron.
The East's greatest philosopher, Siddhartha Gautama, also known as the Buddha, realised the importance of keeping the end in sight. He saw desire as the cause of all suffering, and counselled us not to get too attached to worldly pleasures but, rather, to focus on more important things such as loving others, developing equanimity of mind, and staying in the present.
The last thing the Buddha said to his followers was: 'Decay is inherent in all component things! Work out your salvation with diligence!' As a doctor, I am reminded every day of the fragility of the human body, how closely mortality lurks just around the corner. As a psychiatrist and psychotherapist, however, I am also reminded how empty life can be if we have no sense of meaning or purpose. An awareness of our mortality, of our precious finitude, can, paradoxically, move us to seek – and, if necessary, create – the meaning that we so desperately crave.

Inventions with revolutionary potential made by a mysterious aerospace engineer for the U.S. Navy come to light.
- U.S. Navy holds patents for enigmatic inventions by aerospace engineer Dr. Salvatore Pais.
- Pais came up with technology that can "engineer" reality, devising an ultrafast craft, a fusion reactor, and more.
- While mostly theoretical at this point, the inventions could transform energy, space, and military sectors.
The U.S. Navy controls patents for some futuristic and outlandish technologies, some of which, dubbed "the UFO patents," came to life recently. Of particular note are inventions by the somewhat mysterious Dr. Salvatore Cezar Pais, whose tech claims to be able to "engineer reality." His slate of highly-ambitious, borderline sci-fi designs meant for use by the U.S. government range from gravitational wave generators and compact fusion reactors to next-gen hybrid aerospace-underwater crafts with revolutionary propulsion systems, and beyond.
Of course, the existence of patents does not mean these technologies have actually been created, but there is evidence that some demonstrations of operability have been successfully carried out. As investigated and reported by The War Zone, a possible reason why some of the patents may have been taken on by the Navy is that the Chinese military may also be developing similar advanced gadgets.
Among Dr. Pais's patents are designs, approved in 2018, for an aerospace-underwater craft of incredible speed and maneuverability. This cone-shaped vehicle can potentially fly just as well anywhere it may be, whether air, water or space, without leaving any heat signatures. It can achieve this by creating a quantum vacuum around itself with a very dense polarized energy field. This vacuum would allow it to repel any molecule the craft comes in contact with, no matter the medium. Manipulating "quantum field fluctuations in the local vacuum energy state," would help reduce the craft's inertia. The polarized vacuum would dramatically decrease any elemental resistance and lead to "extreme speeds," claims the paper.
Not only that, if the vacuum-creating technology can be engineered, we'd also be able to "engineer the fabric of our reality at the most fundamental level," states the patent. This would lead to major advancements in aerospace propulsion and generating power. Not to mention other reality-changing outcomes that come to mind.
Among Pais's other patents are inventions that stem from similar thinking, outlining pieces of technology necessary to make his creations come to fruition. His paper presented in 2019, titled "Room Temperature Superconducting System for Use on a Hybrid Aerospace Undersea Craft," proposes a system that can achieve superconductivity at room temperatures. This would become "a highly disruptive technology, capable of a total paradigm change in Science and Technology," conveys Pais.

Another invention devised by Pais is an electromagnetic field generator that could generate "an impenetrable defensive shield to sea and land as well as space-based military and civilian assets." This shield could protect from threats like anti-ship ballistic missiles, cruise missiles that evade radar, coronal mass ejections, military satellites, and even asteroids.
Dr. Pais's ideas center around the phenomenon he dubbed "The Pais Effect". He referred to it in his writings as the "controlled motion of electrically charged matter (from solid to plasma) via accelerated spin and/or accelerated vibration under rapid (yet smooth) acceleration-deceleration-acceleration transients." In less jargon-heavy terms, Pais claims to have figured out how to spin electromagnetic fields in order to contain a fusion reaction – an accomplishment that would lead to a tremendous change in power consumption and an abundance of energy.
According to his bio in a recently published paper on a new Plasma Compression Fusion Device, which could transform energy production, Dr. Pais is a mechanical and aerospace engineer working at the Naval Air Warfare Center Aircraft Division (NAWCAD), which is headquartered in Patuxent River, Maryland. Holding a Ph.D. from Case Western Reserve University in Cleveland, Ohio, Pais was a NASA Research Fellow and worked with Northrop Grumman Aerospace Systems. His current Department of Defense work involves his "advanced knowledge of theory, analysis, and modern experimental and computational methods in aerodynamics, along with an understanding of air-vehicle and missile design, especially in the domain of hypersonic power plant and vehicle design." He also has expert knowledge of electrooptics, emerging quantum technologies (laser power generation in particular), high-energy electromagnetic field generation, and the "breakthrough field of room temperature superconductivity, as related to advanced field propulsion."
Suffice it to say, with such a list of research credentials that would make Nikola Tesla proud, Dr. Pais seems well-positioned to carry out groundbreaking work.

The patents won't necessarily lead to these technologies ever seeing the light of day. The research has its share of detractors and nonbelievers among other scientists, who think the amount of energy required for the fields described by Pais and his ideas on electromagnetic propulsions are well beyond the scope of current tech and are nearly impossible. Yet investigators at The War Zone found comments from Navy officials that indicate the inventions are being looked at seriously enough, and some tests are taking place.

These Roman Emperors were infamous for their debauchery and cruelty.
- Roman Emperors were known for their excesses and violent behavior.
- From Caligula to Elagabalus, the emperors exercised total power in the service of their often-strange desires.
- Most of these emperors met violent ends themselves.
We rightfully complain about many of our politicians and leaders today, but historically speaking, humanity has seen much worse. Arguably no set of rulers has been as debauched, ingenious in their cruelty, and prone to excess as the Roman Emperors.
While this list is certainly not exhaustive, here are seven Roman rulers who were perhaps the worst of the worst in what was one of the largest empires that ever existed, lasting for over a thousand years.
Officially known as Gaius (Gaius Caesar Augustus Germanicus), Caligula was the third Roman Emperor, ruling from 37 to 41 AD. He acquired the nickname "Caligula" (meaning "little [soldier's] boot") from his father's soldiers during a campaign.
While recognized for some positive measures in the early days of his rule, he became famous throughout the ages as an absolutely insane emperor, who killed anyone when it pleased him, spent exorbitantly, was obsessed with perverse sex, and proclaimed himself to be a living god.

Among his litany of misdeeds, according to the accounts of Caligula's contemporaries Philo of Alexandria and Seneca the Younger, he slept with whomever he wanted, brazenly taking other men's wives (even on their wedding nights) and publicly talking about it.
He also had an insatiable blood thirst, killing for mere amusement. Once, as reports historian Suetonius, when the bridge across the sea at Puteoli was being blessed, he had a number of spectators who were there to inspect it thrown off into the water. When some tried to cling to the ships' rudders, Caligula had them dislodged with hooks and oars so they would drown. On another occasion, he got so bored that he had his guards throw a whole section of the audience into the arena during the intermission so they would be eaten by wild beasts. He also allegedly executed two consuls who forgot his birthday.
Suetonius relayed further atrocities of the mad emperor's character, writing that Caligula "frequently had trials by torture held in his presence while he was eating or otherwise enjoying himself; and kept an expert headsman in readiness to decapitate the prisoners brought in from gaol." One particular form of torture associated with Caligula involved having people sawed in half.
He caused mass starvation and purposefully wasted money and resources, like making his troops stage fake battles just for theater. If that wasn't enough, he turned his palace into a brothel and was accused of incest with his sisters, Agrippina the Younger, Drusilla, and Livilla, whom he also prostituted to other men. Perhaps most famously, he was planning to appoint his favorite horse Incitatus a consul and went as far as making the horse into a priest.
In early 41 AD, Caligula was assassinated by a conspiracy of Praetorian Guard officers, senators, and other members of the court.
Fully named Nero Claudius Caesar, Nero ruled from 54 to 68 AD and was arguably an even worse madman than his uncle Caligula. He had his step-brother Britannicus killed, his wife Octavia executed, and his mother Agrippina stabbed and murdered. He personally kicked to death his lover Poppeaea while she was pregnant with his child — a horrific action the Roman historian Tacitus depicted as "a casual outburst of rage."
He spent exorbitantly and built a 100-foot-tall bronze statue of himself called the Colossus Neronis.
He is also remembered for being strangely obsessed with music. He sang and played the lyre, although it's not likely he really fiddled as Rome burned in what is a popular myth about this crazed tyrant. As misplaced retribution for the fire which burned down a sizable portion of Rome in the year 64, he executed scores of early Christians, some of them outfitted in animal skins and brutalized by dogs, with others burned at the stake.
He died by suicide.

Like some of his counterparts, Commodus (a.k.a. Lucius Aelius Aurelius Commodus) thought he was a god — in his case, a reincarnation of the Greek demigod Hercules. Ruling from 176 to 192 AD, he was also known for his debauched ways and strange stunts that seemed designed to affirm his divine status. Numerous statues around the empire showed him as Hercules, a warrior who fought both men and beasts. He fought hundreds of exotic animals in an arena like a gladiator, confusing and terrifying his subjects. Once, he killed 100 lions in a single day.

The burning desire to kill living creatures as a gladiator for the New Year's Day celebrations in 193 AD brought about his demise. After Commodus shot hundreds of animals with arrows and javelins every morning as part of the Plebeian Games leading up to New Year's, his fitness coach (aptly named Narcissus), choked the emperor to death in his bath.
Officially named Marcus Aurelius Antoninus II, Elagabalus's nickname comes from his priesthood in the cult of the Syrian god Elagabal. Ruling as emperor from 218 to 222 AD, he was so devoted to the cult, which he tried to spread in Rome, that he had himself circumcised to prove his dedication. He further offended the religious sensitivities of his compatriots by essentially replacing the main Roman god Jupiter with Elagabal as the chief deity. In another nod to his convictions, he installed on Palatine Hill a cone-like fetish made of black stone as a symbol of the Syrian sun god Sol Invictus Elagabalus.
His sexual proclivities were also not well received at the time. He was likely transgender (wearing makeup and wigs), had five marriages, and was quite open about his male lovers. According to the Roman historian (and the emperor's contemporary) Cassius Dio, Elagabalus prostituted himself in brothels and taverns and was one of the first historical figures on record to be looking for sex reassignment surgery.
He was eventually murdered in 222 in an assassination plot engineered by his own grandmother Julia Maesa.
Emperor for just eight months, from April 19th to December 20th of the year 69 AD, Vitellius made some key administrative contributions to the empire but is ultimately remembered as a cruel glutton. He was described by Suetonius as overly fond of eating and drinking, to the point where he would eat at banquets four times a day while sending out the Roman navy to get him rare foods. He also had little social grace, inviting himself over to the houses of different noblemen to eat at their banquets, too.

He was also quite vicious and reportedly either had his own mother starved to death or approved a poison with which she committed suicide.
Vitellius was ultimately murdered in brutal fashion by supporters of the rival emperor Vespasian, who dragged him through Rome's streets, then likely beheaded him and threw his body into the Tiber river. "Yet I was once your emperor," were supposedly his last words, wrote historian Cassius Dio.
Marcus Aurelius Antoninus I ruled Rome from 211 to 217 AD on his own (while previously co-ruling with his father Septimius Severus from 198). "Caracalla"' was his nickname, referencing a hooded coat from Gaul that he brought into Roman fashion.
He started off his rise to individual power by murdering his younger brother Geta, who was named co-heir by their father. Caracalla's bloodthirsty tyranny didn't stop there. He wiped out Geta's supporters and was known to execute any opponents to his or Roman rule. For instance, he slaughtered up to 20,000 citizens of Alexandria after a local theatrical satire dared to mock him.

One of the positive outcomes of his rule was the Edict of Caracalla, which gave Roman citizenship to all free men in the empire. He was also known for building gigantic baths.
Like others on this list, Caracalla met a brutal end, being assassinated by army officers, including the Praetorian prefect Opellius Macrinus, who installed himself as the next emperor.
As the second emperor, Tiberius (ruling from 42 BC to 16 AD) is known for a number of accomplishments, especially his military exploits. He was one of the Roman Empire's most successful generals, conquering Pannonia, Dalmatia, Raetia, and parts of Germania.
He was also remembered by his contemporaries as a rather sullen, perverse, and angry man. In the chapter on his life from The Lives of the Twelve Caesars by the historian Suetonius, Tiberius is said to have been disliked from an early age for his personality by even his family. Suetonius wrote that his mother Antonia often called him "an abortion of a man, that had been only begun, but never finished, by nature."

Suetonius also paints a damning picture of Tiberius after he retreated from public life to the island of Capri. His years on the island would put Jeffrey Epstein to shame. A horrendous pedophile, Tiberius had a reputation for "depravities that one can hardly bear to tell or be told, let alone believe," Suetonius wrote, describing how "in Capri's woods and groves he arranged a number of nooks of venery where boys and girls got up as Pans and nymphs solicited outside bowers and grottoes: people openly called this 'the old goat's garden,' punning on the island's name."
There's much, much more — far too salacious and, frankly, disgusting to repeat here. For the intrepid or morbidly curious reader, here's a link for more information.
After he died, Tiberius was fittingly succeeded in emperorship by his grandnephew and adopted grandson Caligula.
- As the material that makes all living things what/who we are, DNA is the key to understanding and changing the world. British geneticist Bryan Sykes and Francis Collins (director of the Human Genome Project) explain how, through gene editing, scientists can better treat illnesses, eradicate diseases, and revolutionize personalized medicine.
- But existing and developing gene editing technologies are not without controversies. A major point of debate deals with the idea that gene editing is overstepping natural and ethical boundaries. Just because they can, does that mean that scientists should be edit DNA?
- Harvard professor Glenn Cohen introduces another subcategory of gene experiments: mixing human and animal DNA. "The question is which are okay, which are not okay, why can we generate some principles," Cohen says of human-animal chimeras and arguments concerning improving human life versus morality.
