There are at least 2 definitions of resilience: (1) a material definition points at the “ability to return to an original form or position after being compressed, extended or curved, and (2) a immaterial or psychological definition. The latter one describes the ability to recover, be happy or successful anew having overcome a bad or challenging experience. The American psychological literature defines resilience in the shortest form as “positive adaptation despite adversity”. The psychological construct is linked to a positive life span perspective of personal development. Other areas of application range from “resilient investments”, “resilient industries” to single resilient societies or intergovernmental organizations like the European Union or NATO.
The challenges to resilience increase with complexity of societies and social as well as technical systems. As supply chains have become longer in time and travelling longer distances as well, the improvement of resilience has become a steep challenge for globalization. Reorganizing supply chains with “own sourcing” as in countries which are cut-off from international trade will have huge consequences on sending and receiving countries.
Last, but not least, countries like Ukraine demonstrate the fact and virtue of resilience after more than 1000 days of the massive Russian invasion of its country, which threatened its survival. Resilience works best in networks of organizations and countries. Solidarity is a fundamental building block of resilience as well. Donations and funds support activities that foster resilience. 
On Woke-ability
The past particle of “to awake” is “woke“. As early as the 1960s the term woke has appeared in a New York Times article to reflect the idea that in the African-American History movement you woke up to a new movement, leaving behind discriminatory practice and rhetoric. The definition of woke in dictionaries refers to an awareness of social facts and injustices. Additionally, the use of woke has implied a need to act upon injustices due to social and/or ethnic origin. Elements of the woke movement were the use of more general non-discriminatory terms like people of color (POC) in official documents and revisions of textbooks for pupils. Subsequently, the application of the term woke spread to other social concerns like the discrimination of LGTBQ+ people in many societies.
The underlying concern was and still is (1) to recognize the discrimination and disadvantages faced by many groups in society and (2) a call for changing the way we talk about it and (3) a shift of policies to counter social injustices. Societies differ in the capacity of “woke-ability”, i.e. the capability to address social inequalities of various types including intersectionality. Societies have never simply been only homogenous. Heterogeneity, plurality and complexity are much better suited to represent societies, regions or countries. It is our willingness to deal with these complexities in an open way which includes the “woke-ability” of social phenomena. Acknowdge a social problem and act upon it. Change the way we talk about a problem and the discoursive practice in general are important steps to address old and new social problems. For example, over the last 50years the discourse with respect to handicapped persons has evolved and the Paris 2024 Paralympics have made this clear to the public on a global scale.

On Temporality
Time is passing, or is it? We tend to confound time, with passing of time or an occurrence at a specific point in time. Time has a static use, which refers to a date of birth or date of death. Time refers to durations like the lifetime or time in office of a person or a political leader. In most such cases time is considered as a continuous and linear process. The concept of temporality questions these common perspectives on time to allow additional time perspectives in the description and understanding of time.
Temporality is linked to a more flexible view on the periodization of history. The time before and after the 12 years of Nazi-terror will then be part of the extended periodization of the Nazi-Regime in Germany and Europe. Similarly, temporality widens the perspective on social phenomena by linking historical events to the time before and maybe even to what follows, seen as a consequence of the temporal and spacial co-evolution.
A deviation from the static view of time and a rigid periodization of fascism allows to study the Russian male dominated political authoritarianism as a new wave of fascism in Europe, which negates the right of existence of the state of Ukraine in its neighborhood.
Temporality expresses the need to go beyond a simplel periodization to include a spacial dimension in the defintion of time, much like modern physics does in relativity theory. Temporality, therefore, opens up a “thought space” beyond just the timing of events, which may challenge many of our day-to-day experiences. Cultures with a different understanding of time or the pace of time become a “sound board” for our way of considering and being captured in a time space. Probably many artists are forerunners in playing with time and the way time is “treating” them. Most of them face(d) hardship during their lifetime, but have an extended “after life” in terms of reputation. Some contribute to the perodization in the arts and of their time. They all shape(d) temporality.

On ambiguity
Ambiguity is defines as something which can have more than precisely defined meaning. In legal affairs or other domains this may cause confusion and invites discussions or clarification. It has become even a personality trait and a competence to endure ambiguity. If a manager distributes tasks, ambiguity creates a potential for misunderstanding. However, ambiguity may also leave room for self-organization that people might like or be afraid of. Hence. handling of ambiguity is something of a skill that you are able to operate in less well or even undefined situations or circumstances. In such cases you have make decisions yourself and take responsibility later on for your decision. Creating ambiguity or ambiguous situations is a technique in art as well. To throw into doubt what previously was the received wisdom challenges people and institutions. The ways to handle ambiguity become a challenge to the performance of individuals or institutions. In dialectic thinking you think of something as well as the opposite. The result is an ambiguity which you might want to resolve. Quantum physics created a similar challenge to classical physics as more than one kind of behavior of particles is possible. Ambiguity might be more the rule than the exception despite our continuous efforts to disentangle ambiguity. 
On Intersectionality
Society deals with individualization or individualism in various forms. One way is to take each social group as a specific singular case. This is reasonable and justified in many instances. There are cases where this form of dealing with specific social groups comes to limits. Following the rationale of plurality and individualism it has become common practice to address each target group in a specific manner. Intersectionality, however, acknowledges the overlapping of target groups, which necessitates a more specialized approach to intersecting (social) phenomena. Gender might not be the single most important factor to describe a person, just as age is a concept of various intersections. Chronological age versus age defined through biomarkers demonstrate the variety and potential for intersectionality. The Paralympics 2024 in Paris gave another positive example of intersectionality as extraordinary persons achieved previously unimaginable world records in specicialized disciplines. Individualization and classification is only a first step in the scientific endeavour, the analysis of intersectionality is an additional step to consider in a broad range of fields beyond the social sciences.

On Plurality
Most people are familiar with plurality under the term pluralism with respect to political parties or political systems. We have gotten used to have more than one political party tp represent the right or left in party politics. This is a challenge to people and parties as coalition formation can be a tough challenge to negotiate with a spectrum of parties rather than single representations of opinions and values. Plurality is, however, a more far reaching concept, which is applicable to many other fields of interest. Plurality of living styles are common fields of applications as well. Gender issues beyond binary gender identities qualify as yet another example for the pertinence of the concept. Nature has foreseen a wide variety of species even within subcategories of whatever classification system you apply, just think of trees. A broader variety of individuals is likely to increase the « requisite variety « of evolutionary processes as well. Plurality of modes of transport are another recent example of a widening of technological options available to reaching the same destination. A lot of progress and social progress is relying on allowing plurality to thrive before eventually narrowing down the spectrum. (Image: Sophie Taeuber-Arp, Composition with circles and rectangles, 1932, p. 256 from exhibition catalog 2024) 
On Uncertainty
Uncertainty is a catchword for all sorts of undetermined occurrences, which we might have to confront. We associate economic uncertainty with the difficulty to forecast or predict the economic evolution of key indicators like inflation, GDP, CO2-emissions, energy and raw materials’ prices and availability. Even factors like increases in greed of CEOs, psychological factors like insecurity about external or internal conflicts drive these macroeconomic indicators. Micro-level features of your own stage or evolution of the life course have an impact on and will be affected by uncertainty. Employment, housing, family, or household composition are subject to high levels of uncertainty. These micro- and macro- level factors are, of course, not limited to the domain of economic phenomena. Most recently, political uncertainty has reentered the international and national sphere with the re-election of Donald Trump as president of the United States. This election outcome of the U.S. is perceived by many as increasing the overall uncertainty due to the unpredictability of political decisions and even previous treaties with the U.S. or where the U.S. is a major partner in the agreement. These economic and political uncertainties are accompanied with a perception of growing legal uncertainty even in very personal spheres of life. Last, but not least uncertainty about climate changes like heating up of the planet and more devastating flooding and droughts contribute to increased uncertainty about future developments and the need to initiate adjustment processes and the financing of those.
The individual and societal ways to cope with increased uncertainty are one of the major economic, political, legal and social issues for the coming years. The answers are likely to be found in mutual, cooperative and risk sharing arrangements. The social in society will be a major part of dealing with increased uncertainty.

Commemoration
In The month of November we commemorate those who died and particularly all those who died in the combat for freedom and democracy. The Russian aggression does not show many signs of ending the killing of soldiers and civilians on both sides. Ukrainian forces struggle to resist the Russian occupation of its territory as Russia is sacrificing thousands of lives for small gains of territory it is unlikely to defend in the coming months if Ukraine possesses longer reach weapons. A new spiral of an apocalypse is most probably the result of the Russian insistence on external aggression to cover up more internal problems. A lost generation of young soldiers who died in combat or suffered mutilation will be the outcome of these atrocities. The inflationary effects of wheat and energy prices globally have caused additional casualties in countries that had absolutely no stakes in this war. Russia is to blame for those additional casualties as well as the adverse effects on the world‘s climate due to the fighting and destroyed materials that need replacing later on. The young Russian generation will have to stand up against Putin‘s call to war and put down their weapons. This is one way to end the spiral toward yet another apocalyptic experience in Europe and the silent killing through hunger beyond Europe. (Image: BNF Paris, Apocalypses 2024)
Comprehensive Conflict
In a recent paper Mara Karlin (2024 Foreign Affairs LINK) has stated the need for the Western World to understand and even prepare for comprehensive conflict. Particularly in response to Putin‘s war on Ukraine’s territory and the threats and potential use of the full range of weapons including cyber warfare, destruction of energy resources and military production sites the current war comes close to total war. Several European countries have made significant steps to increase budgets for the new forms of comprehensive conflict management. This starts with adequate discussion in public on the dramatically changed security situation after the „Zeitenwende“ caused by Putin. The forceful Ukrainian response with much financial assistance from the West has pioneered drone counter strikes and by this put an end to the Russian progression into its territory. In order to match the total war ideology Putin is implementing in Russian society the Western world will have to rethink production models and strategic defense capabilities in all areas to match the rather real threats by Russia. The prevention of the spreading of comprehensive conflict is of utmost importance since the risk of an expansion of Russian influence and suppression of any internal resistance in Russia has devastating consequences. The 2024 book by Tatjana Tönsmeyer „Under German Occupation, Europe 1939-1945“ (own translation of German title) demonstrates what it meant to live under the domination of an inhuman dictatorship which is ready to use all out war and violence at any occasion. We have to confront this, even if we don’t want to face it. Nevertheless, the Russian aggression is also strongly targeted on its own people not to take risks of separation from Russia as this would mean devastating destruction to those regions and people who dare to do so. External explosions are therefore for Putin a prevention of implosion of the Russian Federation similar to the Soviet Union previously. Comprehensive Conflict extinguishes any remaining internal opposition as intended collateral damage. In Western countries, however, we shall have to argue with opponents and build majorities through understanding the issues at stake not through silencing opponents and opposition. The debate about comprehensive conflict is only about to start, but it is likely to last for several election cycles. (own image, Contemplation on infinite landscapes, Berlin 2024)
Bi-directional Sleep
For most of us bi-directional sleep is a question of sleeping on the left or right side, or on our back or front, head left or right. In immunology bi-directionality of sleep has another meaning. The immune system is linked to sleep in a bi-directional manner. Good sleep enhances the immune response of cells (direction 1) and infected blood cells for example send a signal to the brain to extend sleep. The study by Huynh et al. (2024) in Nature has demonstrated this bi-directional mechanism. It allowed mice who slept well after an imposed heart attack to recover in a better way than those whose sleep got interrupted during the experiment. The most natural response to a heart attack or acute coronary syndrome is more sleep. This is induced by an inflammatory reaction in the brain, which « orders » your body to increase deep sleep. 😴 Sleep is more than just rest, it may be part of healing. ❤️🩹 (people looking at Caspar David Friedrich „Infinite Landscapes“, exhibition Alte Nationalgalerie Berlin 2024)
History’s Weight
The artist Damien Deroubaix is currently exposed at the BNF.fr in its historic site Richelieu. Together with and next to some of the historic treasures of the BNF collections the unique exhibition allows to experience history’s weight on our current existence. The work of Deroubaix is following and pursuing historic art trajectories with a special historical and ethical consciousness. Techniques of art are insensitive to the moral compass of the painter in history. The collections of the BNF like all major European collections have to handle their colonial past and immoral depictions throughout history. Deroubaix accomplished to liberate techniques of art of their colonial linkages and imagination of emperors focusing on humanitarian values. War is horror, in the past and in the present. Genocide in Rwanda is war crime and dealing with the memories of people an honorable way to look forward conscious of the past. Hybrid forms of art allow multiple contextualizations of his work. In the Galerie Mansart and Pigott of the BNF the historical embedding enriches the art and vice versa. Art allows us to rise beyond the ashes mankind has and continues to inflict on us. (Images: extracts of Damien Deroubaix at BNF, Paris 2024)
Theatre Artists
Performances in the theatre are called pieces. The artists performing are actors of a play. The « Théâtre de la Madelaine », which celebrates its 100th anniversary in 2024 puts on a new production in celebration of the biography of the famous painter Claude Monet.
«Dans les Yeux de Monet » is the inspirational title of the play written by Cyril Gely and scenario by Tristan Petitgirard. Looking through the eyes of Monet puts you into the sometimes tormented head of the great artist. The challenge Monet faces is his very own perspective on a new vision for painting. In order to capture the impression of the cathedral of Rouen on him, he experiments with colours and lighting to capture just the right moment in time. Interesting to remember, there is not just one single moment he paints, but many versions of it with each realization offering a special insight or impression. Just on the sideline we learn about the importance of plurality rather than the one and only unique moment in time.
His own personal difficulties of sufficient funding for his art work and the depression he struggled with are well represented in the script and by the actors.
Galerists as well as donors (Mäzene) encourage artists, but somehow may also contribute to the pressure on artists to produce more creative work. Precariousness of living and living conditions are often a corollary of creativity or the creative process. This is a usually forgotten part of the biography of many past and present artists. Artists have and still contribute so much to humanity, but in most countries the public or private support for artists is sketchy. This remains a societal challenge particularly during times of employment and skill shortages in OECD countries.
Masculinity Photos
After the turn of the millennium we keep questioning us about basic principles of humanity, previously called mankind as well. The Zeitenwende has occurred through Putin and other male warriors and warmongers 2 years ago. This is reason enough to keep asking us what is behind the male visions of life and living together. Any hints from social sciences, biology and media studies are helpful to broaden and deepen our understanding of what constitutes masculinity and how it evolves over the life course and within or between societies. The collection of photographs from Jérôme Prochiantz currently exposed at the BNF enlightened the issue. Ever since Max Frisch wrote „Homo faber“ we are aware of the technological transmission process a man might be subjected to. Capturing single moments or arrangements with a lot of care for details shows maybe otherwise hidden male predilections and leaning towards abstraction. An idea or undefined vision, maybe an illusion are depicted in this revelation of masculinity at the turn of the century. Creative and destructive forces are jointly presented in this continuous questioning of masculinity. (Image: BNF, exhibition 2024-11 Jérôme Prochiantz)
Language Tech
Inclusive societies can build on many tools including AI to lower language barriers. It is not only a question of translation, but many other forms of language come to mind. Sign language or easy language are necessary to facilitate broader access to public services. Reading out texts on webpages or Braille translation for the blind to interact through keyboards are additional forms that are available in digital communication as well. The audio description of videos and images is well advanced (reverse engineered through AI) and allows people with limited vision to fully participate in society. Audio messaging and transcription are used by almost everyone by now. Public services will open up to these channels of communication as well. The technology around languages is much more than just translation and AI-assisted learning of languages (talkpal for example). The new lingua franca is language technology, because it enables us to speak many languages at the same time even dialects or lost languages and in many voices. (Image: Extract of Josef Scharl, the newspaper reader, 1935, Neue Nationalgalerie Berlin)
Ed Tech
Education Technology is much more than the use of tablets and Internet access in schools or in each classroom. Some schools revert to ban mobile phones access during classes or introduce specialized social media breaks during the school day. At the other end of the intelligent use of digital technology is the digital classroom with digital whiteboards in each classroom or the first fun hands-on experience with coding for primary school pupils through, for example, the “Scratch” platform. Once you are used to the power of the whiteboard to use web-based information in teaching systematically, most teachers and pupils will no longer want to miss these tools. Public libraries become important access points for those who have no speedy access at home to assist in learning. Digital tools and e-learning are an empowerment of learners to benefit from the millions of useful learning tools and platforms on the web. A first understanding of easy coding allows children to figure themselves as producer of games rather than only a consumer of fantasy games. Create your own story instead of following the stories of others is empowerment. Scratch it, if you like. The role of the teacher in classrooms is evolving fast as well beyond the 40-60 minutes slots in class. Play the games of your pupils, is a bit like a flipped classroom.

Digital Zebra
It is a difficult task in all countries to bridge the digital divide in a society. On the one hand, there are so-called digital natives, those who have grown up with smartphones and notebooks all around them all the time. On the other hand, there are many persons who have not kept track of the digital turn and feel rather lost or are afraid of making mistakes using digital tools. As public services are also moving online, the need for a society-wide comprehensive mastering of digital information and tools have become a sheer necessity. It is much more than just nice to have.
As public services move online like registrations, payments or tax declarations, the need for training and/or assistance of millions of people in a country become a real challenge. This is where the innovative project “digital zebra” in Berlin comes into play. Through the network of public libraries you can get support in person to master your digital challenges.
The name of the project refers to the “zebra crossing” of a road, which assists persons to move from one side to the other side, just like crossing the digital divide. We shall need a lot of those guides and other multiplyers who can assist people to move safely online. Only through this form of taking people with you on the move towards online public services we shall close the gap of the digital divide. It is probably going to widen before we can narrow it again, unless we breeding digital zebras in a rapid way.

Public health info
Public services have a premordial role to play in providing reliable and up-to-date information on health issues. It is no longer only in charge of collecting this information, for example on infectious diseases, but public services are in charge of timely disemination of that info as well. This is, of course, were online services and AI come into play. Getting out this info is crucial, but in the age of fake news and the wide disemination of news on social media, public services need to check also what becomes of the news they have published. The Covid-19 pandemic has been a worthwhile experience in this respect. It is important that reliable information is transmitted via trustworthy channels, which have already been established prior to the “next” health crisis. Many innovative tools were presented at the SCCON 2024 and maybe trustworthy video calls with a medical doctor or your pharmacist may constitute a solution to many infectious pandemics. However, trust in the technology is important as well as equipment and identification systems to be sure that your medical doctor you meet online is actually a medical doctor or only a savy pretender. The issue is as old as medical assistance. The RKI in Germany is the reference information for coordinated information on many public health issues like infectious diseases.

Forced Living Space
The „Topography of Terror“ hosted the book launch of the research project on „Zwangsräume“ (forced living space or forced homes). The cooperation of an impressive network of organizations (Aktives Museum Faschismus und Widerstand in Berlin e.V., Koordinierungsstelle Stolpersteine Berlin, Alfred Landecker Foundation, Metropol Verlag) has achieved to uncover the forced relocations of thousands of German jewish people from rented place to another one, thereby regrouping and cramping Jews into ever smaller living spaces in predetermined houses within Berlin. Through this horrible step by step expropriation and extermination terror was present and visible all over Berlin. The online documentation and data access allowed citizen science projects to accompany the research and actively contribute to enlarge the data investigated, analysis and dissemination of the findings. The continuation and extension of the project is already in preparation and seeks additional funding and volunteers. The traditional book publication helps to provide an insight into the thorough historical research which started with a more adequate definition „Zwangsräume“ than the previously used term of so-called „Judenhäuser“, since the houses had and kept a mixed population sharing the living spaces until deportations of the jewish persons forced into ever smaller living spaces before. The property of the deported persons was recovered by officials from sealed apartments and sold mostly as bargains on auctions or just redistributed among officials in need or with special merit for the Nazi-movement. This adds an intergenerational dimension to the project that is also worth looking into in the next phase of this extremely valuable project based on large online archives from original register information and other documents. (Image: The map shown below in the presentation has blue signs that have already been traced and hundreds of red signs where the histories are not yet retrieved).
Nazi Reinterpretations
Even almost 80 years after the end of Nazi terror and the 2nd World War started by Germany, we witness attempts to reinterpret the lives and careers of many Nazi officials. In the same realm, the crimes committed to pull out „Stolpersteine“ try to negate the horrible crimes committed by the Nazi leadership and their followers. The special exhibition at „Topography of Terror“ on „Reinhard Heydrich. Career and Violence” allows to study the biography of this high ranking and convinced Nazi official. After the usual career trajectory of a marine soldier he entered the Nazi secret police and made his career moving up the ranks showing readiness to use above average violence. This seems to have been a precondition to qualify for fast career trajectories. These personality traits have been demonstrated for thousands of Nazi officials in their professional life. This exhibition has additional merits to provide shocking evidence that the wife of Heydrich even many years after the end of the Nazi terror and 2nd WW does not show any signs of regret for what were her husband’s crimes against humanity. They had a splendid life and lived in a palace near Prag before her husband died after an attack by partisans. This is a great lesson to sharpen our awareness of those trying to reinterpret the lives of Nazi leaders and many of their followers. It is a timely reminder to not focus on rosy pictures of the Nazi time without the acknowledgment of the responsibility for millions of people who died. (Image: Extract of exhibition on Heydrich, Topography of Terror, Berlin 2024, book publication).
Risk Takers
We are all risk takers of one form or the another. Those of us who ride motorbikes or enjoy rock climbing have an above average taste for risk taking. Since the publication of „The risk society“ we are aware that collectively as a society we have taken on additional risks like nuclear energy, atomic weapons or the risk associated with silent climate change with the persistent reliance on fossil fuels to a large extent. Holman W. Jenkins (WSJ) has added an additional perspective on risk takers which originates from government policies to encourage building homes in places subject to high risks of flooding. Several policies come to mind that encourage individuals to take high risks and construct and repair buildings in flood prone areas. Government grants, insurance policies and relocation subsidies are at issue here. Regulations like driving licenses try to build on competences to ensure „more rational risk taking“ in people. Teaching about nutrition might alleviate the obesity pandemic as much as awareness of an active lifestyle can avoid a large number of cardiovascular diseases. Risk taking should be to a large extent an individual’s choice with the consequence to live up to the consequences of the risks taken also more an individual’s responsibility. Collective solutions are a powerful way to encourage additional risk taking. The consequences of those well-defined solutions have to be funded collectively as well. A society-wide discussion and voting process on such issues has to be organized and updated from time to time. (Image Skateboard high and long jumps Brussels 2024-10)
Aging Politicians
The process of aging is usually a process which is progressing slowly. For politicians this process seems to run in fast forward. The churning of people through careers as politicians is quite unpredictable despite the fact that a career track through youth organizations of political parties or non-governmental organizations is a fairly good predictor of prospects of a career within this party. As the political culture has become even more rough through the comments and criticism of official media and social media, the expectations to be available for comment and debate are almost instantaneous.
Burn-out and frustration are a more frequent occurrence. As such this is not surprising, but the young age of these occurrences are real concern. The profession of politicians bears many risks and even threats to their lives. Democracies rely heavily on politicians who master complex subjects and can communicate effectively about these topics.
Aging societies can no longer just claim that politicians should reflect the age structure of society. It remains a challenge to train and support young people for jobs in politics. It is also an issue to prepare for a sustainable career in politics and keep motivation high to go the extra mile in the interest of society as a whole.

Of or about
There exists a fundamental difference between taking a picture of something or someone as opposed to taking a picture about someone or something. With the term about we denote or refer to a more abstract category of trees, animals or human beings. The use of of, however, refers to a specific realization within a specific category. Painters or photographers have applied this distinction for a long time. It is similar to social scientists who consider persons or relationships as belonging to more general categories. Gender is such a category which has preoccupied us for years before concluding that just 2 gender categories are not enough to come up with reasonable descriptions and predictions of behavior. The realizations of gender are manifold and not necessarily or only binary in nature as well appearances. Eventually social categories are enlarged to fit empirical patterns in more adequate ways. The image of someone/something therefore is something very different from an image about someone/something. (Image of: Children’s corner at Musée Rodin Paris.

Happy Time
“The times are a changing”, so is happiness. This is the spice of life we might add as well. Trajectories of happy life run not as flat lines simply on different, but largely parallel levels. Curves of different persons intersect. Even the focus of what determines personal happiness is different from one person to other. A job-focused person deviates substantially from a person deriving happiness mainly from her/his private life. The time dimension of happiness is yet another puzzle. Some persons have a focus on now and today, others consider a future time perspective for a happy life as less, equally or more important. Even the retrospective experience of happiness or unhappy childhood experiecences can override current emotions and oveall satisfaction with life. Economists apply a so-called discount rate to benfits or costs that accrue in future, which means that 1000 € in future, usually are estimated to have a lower value than 1000 € now. Happiness at some point in time in the future is likely to “suffer” from the same rationale. Satisfaction now is valued higher than even the same satisfaction at a later point in time. This probably explains a large deal why fewer people are concerned with their retirement benefits early on in their professional career and their job satisfaction trajectory. Many artists, apparently have a deviating time horizon. They endure economic hardship now for some recognition in future, but still have a happy time now.

Happy Runner
The happy runner is a nice example of how hard it maybe to experience happiness through running. The so-called runner’s high is available to everybody, if you manage to run long enough already. Most predictions put the threshold distance at about a 1 hour run. The reward for this effort is a special feeling that exceeds the pain or it makes you forget or supress the pain at least temporarily. Special reinforcements can be achieved through the big city runs in exciting places with thousands of people cheering you on. This has become a big business as well. Training for such an event might raise your feeling of happiness substantially. The chemistry of the endogenous production of stimulants of happiness in our body has been enlightened substantially in recent years (partly as doping control). Most of the brain active drugs our body can produce itself, although this involves a lot of physical and mental effort. The rewards are pretty healthy for most runners contributing to their basic level of happiness. Running outside, has contributed more to happiness for me more than the same exercise on a treadmil. Maybe, the environment is part of the happy runner’s high effect. 
Happy Biology
At first glance happiness from a biological perspective is easy to understand. Its hormones, stupid, that regulates it all. Only problem, there are many of them that interact and, apparently, a lot depends on the right dosis and duration of exposure or deficiency. Oxytocin deficiency seems to be a corollary of anxiety and lack of pro-social behavior, potentially making people less happy – to put it bluntly. There are other complex interactions between hormones not only in the circadian circle of humans like for cortisol, but also related to differential reactions to stress. Genetics and epigenetics are involved as well stress regulation and early exposition to stress during the life course has longer lasting consequences later on. How much stress is good for you? Climbing Mountains induces physical stress, but most people report lasting happiness referring back to such singular events. Hormones seem to play tricks with us as well.
Some time after the novel “Klara and the Sun“, endocrinologists have documented the positive effect of a robot on oxytocin levels in humans. Improvements to mental health and well-being are apparently easy considering that oxytocin is a driver of feeling happy as well. Maybe we should take our depressors and drivers of oxytocin more seriously to be “biologically” happy.

Happy Employee
The research on happiness, subjective well-being or overall satisfaction with your life is also an empirical question. Analyses of being happy donot only focus of overall happiness, but look much more into the details of happiness. Beyond the tricky longitudinal observations of happiness it is common scientific practice to deal with subdomains of happiness like satisfaction of employees with their job, satisfaction with one’s job beyond the honeymoon and hangover effect, best known from family studies.
Each of those subdomains has a significant effect on overall happiness. The novel “Happy Life” by David Foenkinos is an interesting example which focuses mainly on the subdomains of job satisfaction, satisfaction with private and romantic partners as the major domains of a happy life. As developed in the novel, people make job changes to re-orientate professional careers or reset their private life. A low point on the happiness scale in one domain might be compensated by higher levels in another domain. These impact from one domaine to another might have substantial time lags involved as well. More drastic resets (à la Foenkinos) can be avoided through focus on other subdomains of overall happiness as well.
How happy are you with your housing situation, neighborhood, your pet, your physical health? There a multiple +/-spill-over effects to overall happiness. Reading a novel might be one as well, just take time reserved to yourself.(Image BnF expo “women in sport”, 20024)
Happy Maths
The link of maths and happiness is not straightforward. Individual accounts of a happy (euphoric) or unhappy (dismal) life are mostly referred to psychologists for treatment. The biografies (documentaries) or fictional biografies told in novels or cinema allow to trace the changing moods of the personalities over time. This resembles life course research. In happiness research social scientist ask questions like “Overall, how satisfied are you with your life“. Measured over time or coded from biografies this allows to reconstruct happiness trajectories. At this point the maths of happiness enter the stage. Long periods of observations yield interesting patterns of curved lines, rarely simple linear trajectories. Social scientist speak of within person variability in contrast to between persons variability. After all, the (short-term superior) happiness of your neighbor might simply be due to the fact that they are doing drugs.
Whatever, try to remember a bit of your high school maths and the bore to deal with “curve discussions or sketching” beyond the manifold shapes of your classmates. Lots of interesting information derives from growth or decline rates, tangent lines, stationary or inflection points. Different starting points or so-called intercepts vary between individuals as well as he potential to cross the Zero-line on one of the axes. Additionally, in geometry you would compare syncronicity of curved lines as well as forms of symmetry for the curve(s). This will simplify or comlexify your perspective on the happiness trajectories of people or characters in a novel.
We are so used to narratives or videoss with a happy end, yet we appreciate the complex trajectories and (multiple) troughs main characters have to pass. Novels teach us about tricky inflection points and subsequent trajectories as well. The maths of happiness, however, is rather simple in comparison.

Happy Life
There are countries in this world that want to prescribe to their citizens what constitutes a happy life. Religious beliefs are another powerful instigation of what may be called a happy life now or in the future. Most people on earth, however, have their very own idea about happiness and how to get closer to this moment, phases or destiny of their lives.
Happy life is also the title of the novel or „une fable optimiste“ by David Foenkinos with the almost programmatic title „La vie heureuse“. It has been qualified as a bit absurd, but at the time of celebrating 100 years of surrealism, this fits into the surreal world episodes and narratives that surround us. The novel is full of ups and downs for the major characters, which reflects the inevitable links of happy relative to unhappy moments in life. The pseudo experience of death allows to press a kind of reset button in life after which love and life can start afresh. This might not work for all us as Foenkinos seems to tell us with the choice of the dedication and citation of Charlotte Salomon „On devait même, pour aimer plus encore la vie, être mort une fois“. Charlotte Salomon, however, lives on through her formidable artistic work accomplished in her short life.
Own Insulin
People who suffer from type 1 diabetes do not produce enough insulin themselves. The World Health organization estimated that „in 2017 there were 9 million people with type 1 diabetes; the majority of them live in high-income countries“ (WHO 2023). The report on successful reprogramming of stem cells of a person to produce insulin again and subsequently transplanting these cells into the same person allowed to produce own insulin again for that same person (Mallapaty, 2024). The hope for millions of people with type 1 diabetes is high that eventually there will be a cure to the disease. Scientists caution that there are no data yet for how long the transplanted own stem cells will produce insulin. Hence, the hope is driving research forward on a promising way forward. The case of type 2 diabetes is very different as additionally the absorption of insulin in the body causes problems. We keep walking and building muscles to facilitate the insulin absorption in the body to guard against the onset of type 2 diabetes. Interaction of diabetes and aging is another topic that needs our attention as rapidly aging societies are at higher risks to face many more people with various forms of diabetes.
Russian Demographics
Dictators prepare their countries long before for upcoming wars. One indicator of such strategies is the pursuit of “natalist” policies. These are demographic policies that aim to increase a country’s population so that the human losses endured during war maybe recovered faster. Russia has had such a policy doctrine in place for quite many years. Only, it didn’t work. Alain Blum and Sergei Zakharov (2023) have shown this in their paper on “L’obsession nataliste de Poutine“. Rather than achieving a growth in the population, at best, the further rather rapid decline of fertility and the population size before the war is reflected in the data (until 2022). The recent objection of youth and women to bear more children is subject of massive opposition of Putin’s forces inside the country. So-called total fertility of 1.5 per woman before the war is as low as or lower than in many other European countries. However, on the other end of aging is mortality or life expectancy. The data show a rather bleak picture of Russia already before the invasion of Ukraine. Based on data published from INED in France Russia has about 1.000.000 more people dying in 2022 than babies born. Bad handling of the Covid-19 pandemic (inefficient vaccines) is also a reason for this dent in population size. Adding outmigration of youth that does not want to stay in a country that goes to war with peaceful neighbors, this bleak population outlook is the disastrous heritage of the Putin years of Russia in the 21st century for generations to come as well.
