The heart of the matter

Heart doctor Michael Henein steps back to consider the unseen and unique wonders of the human body’s design.

Shakespeare famously asked:

“What a piece of work is a man, how noble in reason, how
infinite in faculties, in form and moving how express and admirable, in action how like an angel, in apprehension how like a god! the beauty of the world, the paragon of animals—and yet, to me, what is this quintessence of dust?

Humans may be complex, capable of great heroism and deep depravity, yet it is worth stopping for a moment to look at the human body and mind to marvel in what we have become, and how we are made.

The visible design of the human body points out common features shared along with other members of the animal kingdom. Examples of these features are: two eyes, two ears, two nostrils, one mouth and four limbs, attached to a body and head. Detailed study of different seen parts of the body may, however, show some differences. For example, the presence of fingers and nails, hair distribution as well as a developed tail. While most members of the animal kingdom have teeth and a tongue, those two could also vary in their number and size, respectively, according to different species. Genetic investigations have shown that we humans share 99 % of our genes with animals, suggesting that our “earthly” component shares a common origin. Indeed, the twenty first century scientific findings match what is written in the Genesis story of creation, a story written over 3,500 years ago, well before genetic sciences came to light.

Creatures great and small

As for morphological differences between animal species, it is difficult to naively conclude why some are wild while others are man-friendly-even if the wild ones have different shapes, design, dietary habits, body size and life span.  Other important observed features of the members of the animal kingdom are that they are all born, they all age, then ultimately die.

If we are to look at the unseen features of the members of the animal kingdom, we can again identify similarities. For example, all have a gastrointestinal tract, a cardiovascular system, a reproductive system, a respiratory system, a urinary system and much more. While these systems may differ slightly between species, the overall structure and function achieve similar purposes.  For example, heart speed is faster in small animals like rats compared to big ones like elephants who have very slow hearts. Likewise, the respiratory system and the number of respiratory cycles per minute are significantly faster in running animals compared to the sedentary and slowly moving ones. Finally, the number of offspring also differs in different species, being just one at a time in big animals like elephants and horses, and many offspring in small animals like rabbits and mice. Such paradox between the number of offspring and animal size makes you think of the important determining role of the activity of those animals.

Unseen wonders

Now to turn to the rest of the animal kingdom and the unseen features of the human body. To start, let us look at the amazing functions of the human brain and its various functions. When humanity is sometimes described as the crown of creation, such a description is based on the superiority of human brain function and skills. Its sophisticated structure and how vital centres are created deep in the skull, to be protected from traumas, make you marvel. Also, the brain controls the different functions of the whole body, with its sensory and motor activities, various vital system functions including the lungs and the heart, all endocrine glands’ function, in addition to various receptors and centres that allow utmost precision and accuracy in everything we do. An example of this kind of precision is a doctor feeling a vein or an artery with the tip of a finger to insert a needle or a musician moving a finger a few millimetres while playing a violin, to produce the exact sound needed. Furthermore, the integrated function of human muscles, nerves and spinal cord is also amazing, let alone the synapsis between the nerve endings and muscle bundles, the chemicals secreted in them which allow electric stimulus transmission from the nervous system to achieve the motor function and desired movement.

The human brain also has the unique feature of storing knowledge. Of course, we should not ignore the importance of the training and programming ability of human brain. We learn how to drive a car, how to play games, how to study, how to operate safely on a sick patient.  Such acquired skills are quite limited in other members of the animal kingdom. Moreover, the human brain has the unique ability to invent, discover, improve and correct errors it identifies.

Another very unique feature of human brain is its ability to conduct speech, a feature of humans that is under-developed in other members of the animal kingdom. While most animals can make noise and sounds, only humans can articulate words, sentences and even sing very complex songs. This unique ability seems to be the underlying mechanism behind the development of languages which are based on the human ability to talk and transmit information and knowledge by words and phrases.

The unseen brain has allowed human life to develop over time, building skills and achievements from generation to generation. Millennia ago, humans lived in huts together with animals, and now they build houses and palaces to live in. Centuries ago, we used donkeys, horses and camels to travel but now we use cars, trains, ships and airplanes. Our ancestors burned wood and coal to cook and to warm but now we use electricity to do these.

When we look carefully at the unseen parts of the human body, we also realize that we cannot alter any of it, despite the scientific advances made over the years. We can understand what harms our body and take measures to avoid it. Out of the ability of our brain to discover and invent, we have now produced science-based means for curing various diseases. Consider how we can replace a dysfunctional heart valve or a mobility-limiting joint. These inventions have resulted in a better quality of life, alleviating of symptoms, even helping to avoid early death, in some cases such as heart disease and cancer. 

The heart of the matter

Another unseen source of life in humans is the heart. This fist-size organ is so complex in its structure and function. Recent scientific advances have enabled us to study heart function in milliseconds, hence the development of pacemaker treatments. They have also allowed clear imaging of the inside of the heart and the identification of pathologies, developments that guide practitioners to the optimum treatment of heart conditions. Recent discoveries have also allowed us to better understand how people develop coronary artery disease and how the pathology starts at the innermost layer of the arteries, particularly in individuals carrying significant risks for atherosclerosis including, smoking, high blood pressure, diabetes, high cholesterol and obesity. Amazingly, obesity has been shown to be the strongest underlying cause of other risk factors, hypertension, diabetes and hypercholesterolemia. So, nature cannot be blamed in many of these patients but our own patterns of behaviour. Science has shown that walking at least 5,000 steps each day, complying with the design of our body, reduces the likelihood of developing coronary artery disease by 15 per cent.

The unseen physiology of the rest of our body systems and the interaction between systems make us wonder how we are made.  A rise of our body temperature by one degree due to a bug infection affects all body systems from the brain to the heart. A virus which cannot be seen by the most powerful microscope can destroy our lungs and cause premature death, as was the case with COVID-19 and others.

Finally, human inventions in the form of powerful microscopes have allowed scientists to study the human cell, which is the smallest living component of our body.  Such small cells cannot be replicated in any factory in the twenty-first century, despite the vast scientific developments that surround us. You'll be surprised to learn how complicated and meticulously fine-tuned a human cell is and also how it functions, connects with other cells and other parts of the body. An example of this is the interaction between body minerals, calcium, sodium and potassium with heart and muscle individual cells. Such a function is critically controlled by many factors such as time, electric stimulation and pressure differences producing remarkably harmonious contractions and relaxation of the muscles without missing a beat.

Two years on: the tragedy and the trauma of Gaza

As the anniversary of 7th October comes round again, an ancient story helps shed a new light on this conflict

It is now two years since Hamas' vicious attack on Israeli citizens at the Nova music festival. Two years later, much of Gaza lies in ruins, nearly 70,000 of its people have died, and Israel continues its campaign to rid itself once and for all of Hamas, a hostile neighbour. The spectre of antisemitism has raised its ugly head again on the streets of Manchester. Meanwhile, the world waits to see if the Trump peace plan has a chance of working. 

The world is also deeply divided on the question of who is to blame here. Is it, as the Israelis say, firmly Hamas’ fault, the result of a fanatical Islamist group, sponsored by Iran, determined to extend militant Muslim control over the Middle East in general and Israel in particular? Or, as the pro-Palestinian crowds chant, are we watching a genocide which is the inevitable outcome of Israel’s ongoing occupation of the West Bank and Gaza? Everyone is pushed to decide. As a child of a friend asked his mum the other day: “Which side are we on?” 

Yet what if we try to see this conflict in a different light - not so much in terms of blame but pain?

Echoes of the past

Of course, this is not the first time there has been war between the people of Israel and their enemies on the coastline of Gaza.

The book of Judges in the Bible recounts a series of confrontations around 3,400 years ago between the Israelites and the Philistines, who harassed and taunted the Hebrew tribes as they struggled to establish themselves in the land of Canaan (NB - the Philistines are not the ethnic ancestors of modern Palestinians, despite the similarity in name. The Romans. partly to annoy the Jews, simply decided to change the name of the region from Judaea to Palestina.)

One of those ancient stories tells of Samson, an immensely strong Israelite warrior, who kills numerous Philistines in a spree of violence lasting several years. Samson eventually marries a Philistine woman, Delilah, who betrays him into the hands of his enemies. He is captured, and his eyes are gouged out. In a final act of violence, he brings down the roof of the Philistine Temple at the height of a religious feast, killing both himself and more of his enemies than he killed in his lifetime.

The story is both a tragedy and a trauma. John Milton’s great verse drama Samson Agonistes, written around 1650, presents Samson as a tragic figure, gifted and heroic, a hero of Israel brought low into his Gazan prison by a fatal character flaw of pride and lust, betrayed by his cunning wife, and in his famous phrase, ‘eyeless in Gaza at the mill with slaves, Himself in bonds under Philistian yoke’. The tragedy ends in his final act of destruction of both himself and his enemies.

Yet besides a tragedy, this is also trauma. The roots of the trauma lie deeply hidden in the history between Israel and the various tribes that surround them. Samson is one of many dragged into a history of tit-for-tat violence which ends in this scene of death and devastation. In the story of the Bible, he is caught up in the long history of human wrongdoing – as both victim and perpetrator - that stretches right back to Adam and Eve in the garden. The result is Samson and his enemies all lying dead in the rubble of a demolished building in the heart of Gaza.

In this one small strip of land today we find two peoples living out the trauma of what has happened to them in the past. And without a new approach, the result will be the same – destruction and devastation.  

On many trips to Israel/Palestine over the past 35 years, as I listened to Palestinians and Israelis look at the same issue with such different eyes, this conflict often struck me as both a tragedy and a trauma. That sounds bleak. Yet this perspective can, despite its apparent gloom, bring a glimmer of hope.

Tragedy and trauma don’t avoid the question of blame, but they don’t start there. They start with a posture of empathy. Tragedy makes us pause before making moral judgments and instead, simply to notice and enter into the sadness, the grief of it all. When we watch the final scenes of Hamlet or Macbeth, or even the Samson story, we are simply left in silence. We don’t rush to judgment, but simply acknowledge the heart-breaking sorrow experienced by the ordinary people caught up in this. Tragedy sits with the grief and darkness, and does not reach immediately to blame, realising that real life is usually more complex and the causes of conflict more opaque.

At the same time, understanding this as trauma forces us to enter into the pain underlying the conflict. Samson is born into traumatic times with his people under attack, and ends up living out the trauma he has experienced by brutal revenge on his enemies. In a similar way, in this one small strip of land today we find two peoples living out the trauma of what has happened to them in the past. And without a new approach, the result will be the same – destruction and devastation. 

The Jewish people of today, especially in Israel, remain deeply traumatised by the history of anti-Semitism which climaxed in the Holocaust of the 1930s and 40s. A determined attempt by a sophisticated, modern European nation to systematically exterminate every single one of the Jewish race is not just a historical event but one whose ripples or perhaps better, stormy waves, reach us today. Alongside this there is the expulsion of Jews during the C20th from Muslim countries such as Syria, Iraq, Yemen, Algeria, Tunisia and Libya. For those of us who are not Jewish it is hard to imagine the impact of such a reality, not just as a fact of history but as a real danger in the future. After all, if it happened once, it could happen again. It explains why Israel has always paid scant attention to international opinion and resolutions of the UN for a ceasefire, such as the one recently called for. As the Jewish writer Daniel Finkelstein put it:

“The origin of the state of Israel is not religion or nationalism, it is the experience of oppression and murder, the fear of total annihilation and the bitter conclusion that world opinion could not be relied upon to protect the Jews. So, when Israel is urged to respect world opinion and put its faith in the international community the point is rather being missed. The very idea of Israel is a rejection of this option. Israel only exists because Jews do not feel safe as the wards of world opinion. Zionism, that word that is so abused, so reviled, is founded on a determination that, at the end of the day, somehow the Jews will defend themselves and their fellow Jews from destruction. If world opinion was enough, there would be no Israel.”

So, with such a trauma behind them, it is not surprising that when a Muslim kills Jews in a British synagogue, when rockets rain down on Israeli towns, or Hamas militants swagger through kibbutzim, shooting people just because they are Jews, it triggers exactly the memory of the trauma that they have been through as a people. What Palestinians think of as resistance to an occupation of their land, is experienced by Israelis as an echo of the desire to exterminate the entire Jewish people, in a way that sends a shiver down the spine for anyone who has lived this story.

Just like Samson and his enemies. An eye for an eye leads both to end up eyeless in Gaza.

Yet the Palestinian people also have a trauma of their own. In 1948, at the time of the creation of the State of Israel, hundreds of thousands of Palestinians were made homeless and stateless, deprived of their homes and their land, often at gunpoint, and many killed by Zionist fighters. The Arab nations did little to help, only interested in their own interests. The European nations stood by. America continue to fund Israel so that their army vastly outweighs any other army in the region, and certainly enough to crush the stones, knives and bombs of various intifadas. Their deep sense of injustice also leaves a scar, one that can continue to be used by groups like Hamas for their own purposes.

And so today when Gazans watch their cities pummelled to dust, when Palestinians are made to queue at checkpoints simply to travel from one place to another,  when land is taken through the building of a security wall, and Israeli settlements continue to get permits to build on Arab land, while it is much harder for Palestinians to get planning permission to build a new home, all this triggers the memory of what Palestinians call the Nakhba or the disaster. What Israelis see as legitimate self-defence, security measures to keep terrorists at bay and to keep their people safe, is experienced by Palestinians as an echo of their own past trauma of dispossession.

The result is that both sides end up caught yet again in a cycle of violence, just like Samson and his enemies. An eye for an eye leads both to end up eyeless in Gaza.

Yet this approach perhaps places upon us who look on, the responsibility to try to enter into the pain of the other side.

Now of course, we can argue about which trauma is the greater. We can debate the merits of each moral case, or where real blame lies. But trauma doesn't work like that. Trauma sits within the mind and the body, and spreads, overwhelming any ability to cope normally and react with a sense of proportion and balance. The effects of trauma are not deliberate or logical but involuntary. Reactions to trauma are notoriously complex and differ according to individuals. Trauma stays with individuals for years and with communities for generations.

Understanding this conflict not so much as through the lens of blame but of pain may help us understand this conflict differently. Of course, it doesn't avoid the question of blame, because terrible things have been done here. It also doesn’t deny Israel’s right to defend itself against Hamas’s attack with legitimate force. Most of us tend to lean towards one side or the other of the conflict. Yet this approach perhaps places upon us who look on, the responsibility to try to enter into the pain of the other side. And when the dust of battle settles, it perhaps promises a better way to cut the cycle of violence in the future.

Understanding this conflict as both tragedy and trauma helps us see it in a new light. And perhaps it gives us the glimmer of a hope of a way forward. The memory never goes away, but trauma victims can find ways to approach the memory of what happened to them in different ways.

The story of Samson ends with destruction and his burial in the family tomb. It ends in death. Within the long story of the Bible, however, the chaotic period of the Judges is superseded by the monarchy – the kings of Israel, the best of whom is King David – a ruler with flaws, but described as ‘a man after God’s own heart’. Beyond that, the story of David points to a later ruler also born in Bethlehem, whose rule meant not hating and killing his enemies, but loving them to the point of dying for them, thus, finally, bringing peace. It is that kind of Jesus-shaped, self-sacrificial, radical, counterintuitive leadership on both sides that can show a way out of the cycle of violence and hatred that was there in the period of Samson, and is there today.

Only leaders who are not concerned with doing whatever it takes to stay in power, nor willing to sacrifice others for their own purposes, who don’t care about personal reputation, but are willing to take the risky path of reconciliation, as I have argued elsewhere on Seen and Unseen - only this kind of leadership can lead us beyond the tragedy and trauma of the past into a more hopeful future.

The last word might come from Audeh Rantisi, a Palestinian evicted from his home in Lydda in 1948. He went on to become an Anglican priest and an activist for reconciliation between Jews and Arabs and the need for both to recognise the scars and humanity of the other:

I still bear the emotional scars of the Zionist invasion. Yet, as an adult, I see what I did not fully understand then: that the Jews are also human beings, themselves driven by fear, victims of history's worst outrages, rabidly, sometimes almost mindlessly searching for security.

Four years after our flight from Lydda I dedicated my life to the service of Jesus Christ. Like me and my fellow refugees, Jesus had lived in adverse circumstances, often with only a stone for a pillow. As with his fellow Jews two thousand years ago and the Palestinians today, an outside power controlled his homeland - my homeland. They tortured and killed him in Jerusalem, only ten miles from Ramallah, and my new home. He was the victim of terrible indignities. Nevertheless, Jesus prayed on behalf of those who engineered his death, "Father, forgive them..."

Can I do less?
