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 able 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.
Traffic Speed
Most people use cars or other automotive vehicles (e-bikes, e-scooter) to get faster from point A to point B. However, speed of traffic causes trouble for other groups of mobile persons. Demands on attention rise, despite the abundant use mobile phones even during driving a car. Mapping systems and services from A to B have become an almost daily exercise. Statistics on road accidents that involved inadequate speed are between 20 and 30 percent of all deadly road accidents, depending on the source of information and country (Example D). Frequently, speed is not the only cause, but other behavioral mistakes occur jointly.
Traffic signs are a basis to make drivers aware of accident prone locations. Too many of them may even lead to the opposite effect of ignoring the signs. Reducing the speed of traffic in inner cities is a steep challenge and many cities invest substantial amounts of money and effort to monitor and try to control better excessive speed. Schools, sports centres and shopping areas are all hot spots of automotive and pedrian encounters. They deserve special attention. Penalizing excessive speed is one way to nudge behavioral change. Although the statistics on the huge amounts of penalties awarded does not seem to alter the behavior of traffic participants in the short run. For some it appears to be a regular part of their budget of mobility with no consequence for behavioral changes.
For years the dangers of inadequate traffic speed in cities made young families and older persons leave more risky inner cities, but adaptations of hot spots and increased control systems seem to work in the long run. The “externality” of inadequate traffic speed is higher costs for the health system and society at large. About time to make a “behavioral turn” in traffic speed.
Sufficient
What do we mean by sufficient? Sufficient of what? French philosophers currently debate the topic under the French notion of sobriété (sobriety). They give as English translation sufficiency, but the notions do not match exactly in the usual understanding of the words. In breaking with the economic rationale of more is always better, the idea of having sufficient food, room to live in or social contacts to not feel lonely, the notion of sufficiency hints towards a rethinking of our customary lifestyles. How many trousers are sufficient? Well, as with shoes there might be gender differences or more generally interpersonal differences or preferences to come to the conclusion of how many is sufficient. If we bring in the notion of sobriety in additional, we allow another social and/or ecological dimension. This may redefine what is sufficient based on judgments how much our planet can handle (emissions) and distributional judgments. The western lifestyle of the last 100 years is no role model for other countries to follow. It is urgent to rethink our growth based economic model to develop new socially viable ways of production and consumption. It seems to be a necessary condition to reconsider the notion of wellbeing and wealth from a sufficiency perspective. It is a sobering thought, isn‘t it?
Phase Shifting
The Berlin “Hamburger Bahnhof Nationalgalerie der Gegenwart” recently acquired “Phase Shifting Index” by Jeremy Shaw. As part of an exhibition of new acquisitions, Sam Bardaouil, the director of the museum and curator of this exhibition has installed the large-scale video and sound installation at the end of the long corridor of the “Rieckhallen”. The impressive, even overwhelming art work was created in 2020. It was first shown at the Centre Pompidou in Paris.
The piece consists of seven large suspended screensand creates a space like in dance club, discotheque or dance studio. The visual and sound experience is allmost psychedelic. The near obsessional dancing shown on the screens represent different periods of dancing with their particular patterns of movements and choreographies. The phase of the electromagnetic waves is shifting from one screen to the other and towards the end of the performances it becomes clear, that they all follow a similar wave or rave pattern. Sublimation or ecstasy are the underlying index-like common traits. Each period or decade 50s, 60s, 70s, 80s, 90s, all had their peculiar dance and movement patterns. The video-installation is like a history of art of expression through body movement, amplified and indexed through rhythm and sound.
Electromagnetic waves can be characterized through wave shifting in various forms. This work gives us a feeling for the fascination of movement and phase shifting emotions. Don’t worry, the immersion ends after 10+ minutes and, if you like, you might read up on the physics of electromagnetic waves and phase shifting to calm you down.

Walking Danger
Autumn brings color into nature. This is for some the bright side of life. However, the sun sets much earlier every day and many people begin to walk to school or work and back during the dark time of the day. Unfortunately, this entails an additional danger to those walking the cities as bad light conditions cause many accidents of pedestrians. The statistics provided by Destatis (2024) for Germany show a marked increase of walking accidents from September onwards and lasting throughout winter. Equip yourself with bright colors and reflectors to avoid being a walker in danger or a walking danger. On Sunday it is pretty safe to go for a stroll. City life is less stressful and professionals in a hurry usually take a rest on that day. The conclusion is to choose your track wisely in order to feel safe on weekdays.
Innovation Painting
Innovations have fascinated painters just as much as photographers. The impressionists have painted trains and steel bridges as well as modern city life. Innovations change the atmosphere of a situation and new forms of transportation have been admired for many decades. Artists and painters have dealt with this phenomenon in various ways. Either the innovations have puzzled the normal vision of people or things or the artists hinted at curiosities or incompatibilities. Gustave Courbet has depicted in a unique style (Realism), as early as 1865, a seated woman with a paddle on something similar to a catamaran. It is maybe surprising that the modern form of stand-up paddling looks a little bit like the „podoscaphe“ painted by Courbet. Innovations in sports continue to evolve and become part of Olympic Games as well. Some disciplines make it into the Olympic canon rapidly, others never make it. The exhibition of „Artists and Sport“ gave ample opportunities to reflect on the the relationship of artists and innovations as well. (Image Musée Marmottan Monet, Paris 2024, Extrait de Gustave Courbet, Femme au Podoscaphe. 1865)
Waiting time
A new report by Darzi, a former cancer surgeon and past minister of health in the UK, paints a dismal picture of the British health service (NHS) over the last 15 years under conservative rule. The public service has seen no increase in its budget accounting for population growth and the aging of the population. The service is no longer able “to give patients the timely care they need” (The Guardian 2024-9-12 title page). Increased waiting times lead to an estimated 14.000 premature deaths per year. Darzi presents data that show 300.000 persons had to wait longer than one year for a treatment that should have been performed within 18 weeks.
The staff seems desperate for changes as well as they have to spend more time on management of waiting times, time which is lost for real treatment. The quality of care is another issue which awaits urgent attention. Health cannot wait for most patients, but the neglect of investment in hospitals and people is expensive in the longer run. Even the reform efforts should not wait any longer. Time is a precious good and each life matters. (Image back cover of exhibition catalogue Käthe Kollwitz at MOMA 2024).
Desertification
Since 2018 we have evidence of the progression of desertification into some Member States of the European Union. The mediterranean countries are concerned as well as regions of Bulgaria and Romania near the Black Sea. There are multiple sources of desertification. The 3 main reasons of desertification are soil erosion, loss of soil fertility and loss of natural and desirable vegetation besides wind or water erosion and salinization. We also know that man-made climate change is at the root of the past and recent problems. The statistical indicators of land degradation are collected by the European Joint Research Centre and these data show a dismal picture of land degradation in general and desertification as part of this process. A study by Ilea et al. published in Nature 2024 projects an intensification of extreme weather in the coming years. Higher temperatures will most likely enhance desertification and more frequent flooding will contribute to more soil erosion as well. It is a rather strange process that we know we are creating severe problems for some regions which endanger the roots of their existence and yet we do not act upon those undeniable facts (United Nations SDGs list). The amount and dynamics of land deterioration put the global South under severe pressure, but also the wealthy parts of the Mediterranean basin will be affected. It about time to acknowledge that we are all part of the global changes and challenges. (Image palm tree in Paris, Jardin du Luxembourg, 2024)
Heat Stress
Heat causes cardiovascular and pulmonary stress. This has been well-known for a long time. A newly published epidemiological study for Germany reiterates this finding and adds more details to the picture of who is affected most by heat stress and heat-related mortality. Old age and being female increase the heat-related deaths in Germany according to the study by Zhang et al. (2024) published in the Lancet Regional Health. Our body’s thermoregular responses to heat stress like vasodilation or hyperventilation cause additional stress to our cardiovascular and pulmonary system. Excessive sweating and dehydration, possibly increased through medication, amplify heat-related risks. The study corrects the estimates by using fine particulate matter (PM2.5), ozone (O3), and nitrogen dioxide (NO2) data on the district level in the analysis. High concentrations of PM2.5 and NO2 increase heat stress and related deaths as well. Inner cities are, therefore, not the best place to be during the hot season. Most southern European inhabitants of big cities are aware of these health hazards and act accordingly. In Germany it is much less a habit to quit inner cities during the hot days in summer, but climate change will make this a major concern. Greening inner cities is an urgent necessity, which is not just nice to have, but saves lives. (Image Berlin Bears, Berlin City Center 2023)
Painter Sociologist
In going to a gallery and exhibition of paintings from the 17th century (Gemäldegalerie Berlin) you do not really expect to attend a class of sociology. However, this is exactly what the Flemish painter Frans Hals does with his paintings of various genres of society of his time. His sociological categories are for example unmarried young persons, married couples or pensioners living in a shared home. Other social categories of interest to him are a caregiver or, more common for the time, persons from noble or wealthy families. His painting „The Regents of the old men’s Almshouse” (ca 1660), the male pensioners home is one of his last paintings when he himself was already about 80 years old. Similar to a College of students the elderly home was run by a house father and house mother who took care of the daily living. The paintings of Frans Hals covered the entire life course with a cross-section perspective of society at his time. From few of his supporters he painted even several images moving towards a kind of longitudinal perspective on a person’s life course. Certainly, with “Oude-mannenhuis” (image below) he was interested not only in individual life courses, but of the conditions, forms or images of aging at his time. He probably was one of the first to challenge the negative stereotypes of aging.
Theatre Archives
The process of creation in the realm of theatre performances has manifold facets. The French National Library (BNF) in Paris has received the archives of the „Théâtre du Rond-Point” in 2023 and honors the donation with a fascinating exhibition on the immense creativity of the author, scenarist and director Jean-Michel Ribes. (Image below) The professional diaries of Jean-Michel Ribes and the documentation through photographs from the performances and video extracts allow an intimate view into the hard work of producing theatrical performances, popular television shows and comedies. Jean-Michel Ribes took notes of all sorts and kept extensive lists of potential collaborators, actors, daily occurrences and just nice sounding phrases. From just a simple phrase heard on the streets he developed a small piece to be performed in shows. Listening to the people and enriching this with great actors in superb scenery made his popular success. The creativity seems to derive from ample note taking and coming back to them eventually.
Paralympic Happiness
It is with great pleasure that we watch the paralympic athletes in Paris compete for Olympic medals. For many the emotions of participation and being applauded by so many people in a sport arena are great experiences. Happiness derives from such great games and audiences. The accomplishments of the athletes and their supporting teams are truly outstanding. The progress towards such high skill levels is remarkable for each of them. The adaptation to what appears to be a handicap with adequate support and technique allows to surpass limitations. Well exercised skills like swimming are possible to be performed with great skill to achieve incredible performances. The Paralympic Games in Paris 2024 are a great reminder that besides the athletes some artists had to struggle with handicaps, but achieved some of the finest pieces of art. Matisse, for example, is called frequently “le peintre-du-bonheur”, the painter of happiness. In his last few years he faced a severe handicap to paint, however the pursuit of abstraction helped him to continue to create masterpieces. The rather radical pursuit of abstraction and maybe simplification are uncovered in the exhibition “Matisse: The red studio” at the “Fondation Louis Vuitton”. This marks an important step in the artistic life course of Matisse and enabled him to continue his work in later life when his health made it very difficult to pursue his artistic work. (Image at Fondation Louis Vuitton 2024-9-1 exhibition Matisse).
Olympics for All
The Paris 2024 Olympic Games and the Paralympic Games have demonstrated the extraordinary competence, professionalism and competitiveness of all athletes. The television spectators and live participants in the events have been involved to a great deal. Considering the probability of getting involved in physical activities and sports High level athletes are most likely to continue their sports activities. In many countries the extraordinary athletes of the Paralympics faced tough challenges to pursue their sport interests and passion. The public health challenge is the big unresolved issue of how to best raise an awareness for the pleasures and benefits of sport for the masses. (bibliography by BNF “Santé et activité physique) It is not only a matter of suitable infrastructure, but also the question of sports in your neighborhood. This issue has implications for urban and rural communities and how they organize the practice of sports in an inclusive way. Each step may be a stepping stone into sports for all ages and pathologies.
Paris libéré
It is with great pleasure to follow how Paris commemorates the liberation of Paris from Nazi-Germany 80 years ago. (Quote from De Gaulle “Paris libéré”.) On the 25th of August 1944 the city of Paris was finally liberated by French armies and the support of the local resistance movement. Similar to the journey of the Olympic flame on the way to Paris, we can follow each city celebrating the liberation from the occupants. Beginning with the landing in the Normandy of the Allied troops, the chasing of the enemy has been a matter of time, but still incurred huge human losses. More than 4 years of Nazi symbols in Paris were finally brought to an end and celebrations on the streets became a symbol for the enormous relief this liberation has meant to the population of Paris, France and hope to many neighbouring, but still occupied territories.
Several documentaries on television and radio allow to empathize with the joy of this time. Enduring the hardships imposed and, for many, risking their lives in clandestine networks of the resistance were honoured by the success of the liberation of the city without the massive destruction, which was to be expected.
A book edited by Ulla Plener (2007) highlights the supporting role played by some women originally from Germany to support the French Resistance movement. It still is not common to understand the retreat of Nazi-Germany also in Germany as the progressive liberation of the country from the terrors of a dictatorship.
Burden of Disease
For the planning of health and care systems it is important to measure the so-called burden of disease within societies or related to specific diseases or social groups. A large-scale analysis of several longitudinal data bases of the populations 50 years of age and older shows that we have underestimated the burden of disease to societies of psychiatric disorders, like depression, in most societies.
A meta-study and overview of previous studies showed already that depression (age 60+) is more common in lower-income countries (between 25 and 33% of 60+population age group). High income countries, studied by Wang et al. 2024 in The Lancet Healthy Longevity, have rates of depression well below these levels, but a link to socioeconomic status, inactivity and loneliness is still evidenced. A five-year follow-up of persons aged 50+ years shows that the probability to develop a depression (hazard rate) is twice as high for persons with low socioeconomic status, who were socially
inactive and lonely than for socially active, high socioeconomic status and did not feel lonely at the beginning of measurement. The conclusion of the research highlights the need to develop and implement integrated and simultaneous initiatives to addressed the growing burden of disease related to depression in older persons.

Stress Ageing
The relationship between stress and aging is a complex one. Stress is known to accelerate aging and aging caused different reactions to stress. In short causality does not run only in one direction. Additionally new research published in Nature Medicine 2024 demonstrates that different genetic preconditions determine different response patterns to stress and subsequent brain aging. From anecdotal experience we are well aware of different persons coping very differently with stressful situations. Mastering of various coping mechanisms may attenuate the stress experience but the impact on preserving our brain remains an open question. Various other forms of lifestyle conditions like drugs and smoking cause specific forms of brain damage as well. 2 separate forms of dementia can be identified from brain MRI-images as well. The brain is no longer the black box of missing information about what is going on in humans. Put to the right purposes this is good news. (Image: break dance shooting Paris St Denis 2024)
