The scientific paper on a revised definition of obesity was produced by the special Commission on Obesity. It appeared in The Lancet Diabetes & Endocrinology in 2025-1. The previously common practice by medical doctors was to classify person in the obesity category based mainly on the simple calculation of the body mass index (BMI = weight/height²). A BMI > 30 put persons into the obese category and stigma.
Since the Covid-19 society-wide testing experience, we are all familiar what it means if you get misclassified and have to live with the consequences (exclusion from work or events etc.). The simplifying and summarizing BMI calculation and classification has also produced many wrong classifications. For example, persons with a lot of muscles (just watch this at any fitness studio) will have a high weight relative to their body height², but they are likely to be more healthy than many other light weight, but seriously stressed persons.
In empirical test theory such cases are the so-called false positive cases, i.e. classified as obese, but not a medical problem at all. Medical doctors and health insurances should not finance special treatments for these persons, which foregoes treatment of other more needy persons.
With new expensive drugs on the market to treat obesity it is even more important to test with more precision the normal, pre-clinical and clinical status of obesity. Fatty tissue or muscles, that is the relevant question. Fatty tissue in muscles is the next level testing issue. 
Covid Literature
In 2025 it about time to evaluate the medium term impact of the Covid-19 crisis in Europe and world. The various lockdowns caused unexpected “spare time” or time in isolation. Some otherwise very busy persons embarked on literary projects during these months. Most of the outcomes have now been published. Most authors would not label their writings as “Covid literature”, since they do not deal with the Covid pandemic in any sense. However, only due to the additional time resources, and maybe writing as a creative coping mechanism, some persons became and dared to become authors eventually.
For some isolation from the usual work context was a lonesome experience, others realized literary projects. Camille Paulhan (edition Sombres Torrents) for example used freed up time to write “Couper à travers les ronces” published in 2021. Her short stories, like narrative clips, range from introspection to memorable encounters with art works and artists. As an expert on “perishable art” Camille Paulhan is particularly sensitive to the “fleeting moments” of encounters and maybe of life itself. The Covid-pandemic has certainly reminded us on the increased risks to our existence during a pandemic. The literature originating during these months and years might reveal specific virtues only ex post.
You might still be able to buy a copy at the publisher. The bookshop and gallery Yvon Lambert (online retrieved on 2025-1-20) says sold out, but shows several pages online. Although books may become a perishable product, some copies will survive due to the efforts of fans of perishable art and moments. 
Artists networking
Creating a network between rather idiosyncratic artists is no easy task. The more they develop a unique style separate from other painters mixing with other artists can be a challenge because you might find yourself in the position to continually defend your new style. Therefore, building a network of artists that understands the concept or emotion that drives you is a great advantage. In the catalog of the Caillebotte exhibition in the Musée d’Orsay Paris the map of living and working spaces of Caillebotte and his artists’ friends like Claude Monet is a great way to demonstrate the degree of networking and creative spaces that propelled the impressionist movement. The galleries and greater exhibitions of the impressionists took place in the vicinity of the established art institutions, but were not admitted into the traditional exhibition centers like the Louvre. The map from the catalog provides insights into the cognitive map of Paris which Caillebotte had in mind at his time. Artists see cities as opportunity spaces which facilitate or impede the creative processes. 
Politician Cycles
In a bookstore which sells books in English or American language we find lots of biographies or autobiographies of politicians. As a politician you don’t even have to be out of politics when your biographical account or your own view is published, let alone be written. Publishers seem to hunt politicians who made headlines, no matter good or bad. Outside the EU you can always sell biographies at half price, if the volumes sit for too long on the precious shelves of bookstores. Most of the biographies are found in the history section of shops or libraries, however some show off in sections like politics (if not dead for too long) or in the business and management sections. Leadership is a big issue in the latter disciplines, but the psychological or sociological literature starts to meddle with the received wisdom of how single person leadership is in fact facilitated with the many great people around the sometimes outstanding single person. Maybe the focus on a single person is an easily understood and simplifying concept of leadership. In the case of Obama (2x) two single historical accounts complement the one person focus. In 2025 Michelle Obama skipped the funeral of Jimmy Carter where she would have had to sit next to Donald Trump (according to the Daily Telegraph and probably endure small talk). Politics appears to move in circles and politicians might find themselves encircled. 
Science and Fiction
We associate with science and fiction the extrapolation of scientific trends into some futuristic settings. The most striking examples of science fiction in novels or video use some scientific findings (dinosaurs, genetic engineering) and project this knowledge into another fictional setting. The usual personal relationships follow rather predictable plots of romance, deception, violence or war.
The novel “Wellness” (Hill 2024) is also a kind of science fiction as it is based on social science evidence and builds its fictional plot firmly embedded into the social and psychological research. The attachment of references (and defending the print of those in translation) underlines the commitment to write a new type of “social science fiction”.
In this innovative style the scientific basis of psychology and sociology is then extrapolated into a fictional arrangement. Research on subjective well-being with the U-shaped form over the life course and the extrapolation of the placebo effect, which is instrumentalized for a business, derive from key topics in the social sciences. In fact, the novel and the background scientific literature in the bibliography could well figure in a social science course at university entry level. These readings constitute a 360-degree-view on personal development and social structures. Of course, social sciences move on and add new evidence on an almost daily basis, but the selection and arrangement of the characters create an innovative social science fiction, without some unrealistic technological extrapolation.
It strangely feels like we are already part of this social science fiction (compare “Klara and the sun” by Ishiguro) as politicians advocate and campaign with placebo topics in elections and project us into some more happy past or future.
The social science fiction of Nathan Hill resembles for me the great utopian novel by George Orwell “1984” published in 1948. A title “2032” instead of “Wellness” could have worked quite well, as the first edition of Nathan Hill’s social science fiction was published already in 2023. (Image: Extract of: Lo Spagnolo, 1665-1747, Hecuba makes Polymnestor blind, MRBAB).
Not learning
For decades our attention has been focused on how learning works. However, at the beginning of 2025 it might be more important to shift our focus of learning research on “not learning”. Recent research on learning includes the study of “social learning” of mice (Winiarski et al. 2025) and the related brain mechanisms that are involved in social learning like the prelimbic cortex.
For our human societies we also rely to a great deal on social learning. In mice, however, the disruption of the prelimbic cortex causes mice to no longer seek “social information related to rewards” from other mice. In Eco-HAB cages these mice follow their scent capabilities to “sort” their information seeking from for example higher “social status animals”. This tested reward seeking behavior allows clues to how learning works. The intervention to disrupt the synaptic plasticity in a later phase of the experiment reveals less social learning from the network social information and fewer contributions to the social network.
Only intact neural plasticity in the prelimbic cortex ensures the maintaining of the social structure. Of course it is highly questionable, whether these results based on animal experiments tell us anything about social structure and social learning in other mammals, but there might be reasons to search for explanations of “no social learning” in humans as well. 
Wellness Sickness
There appears to be some kind of a relationship between the 2 conepts of wellness and sickness. Some would argue that the more sick you are, the more you seek wellness. Sickness seems to be the precursor of wellness for many people. Wellbeing or happiness are even higher order concepts which are only indirectly related to wellness. In an almost 600 pages science and fiction novel, Nathan Hill (Link) constructs his plot based on the psychological research on the placebo effect. With a sufficient aura around a pseudo-medication administered in a wellness clinic, the clients or some figure near the 50% random positive effects are treated with at least no negative side effects. On page 152 we find the more explicit description of how to induce a placebo effect in participants. Context, expectations, faith, symbols, metaphors and story are all ingredients for a placebo effect to work. Sometmes without knowing we receive a treatment in our childhood or throughout the life course that we work on using placebo effects to overcome them. The novel by Hill (2024) is a well researched psychological as well as sociological fiction including a bibliography, which reminds us „If you cling too hard to what you want to see, you miss what’s really there.“ (p. 496). 
Review Year
It is a nice common practice to wish „A happy New Year“ to people at the beginning of another calendar year. It is also a good practice to review the last twelve months yourself or with friends. We spend,however, much less time to listen to friendly or enemy fire as a kind of evaluation of what were the successes and failures of last year. In monarchies in the middle ages a clown or a fool was allowed to present criticisms with funny packaging. Nowadays, comedians have taken over this important role to review experiences and policies that worked or went awfully wrong. All media join in in this tradition and summarize what happened before the next busy months take over. Yes, it is important to devote time to this procedure. There is a risk that it becomes „the same procedure as every year“, but it is never to late to learn from failures or simple mistakes. Failed last year, fail better next year. 
Investment Disinvestment
Asume we live in a world of fixed amounts of investments. The option to invest in a new project or product will automatically reduce the amount of investment in another product. The investment decision, therefore, is subject to opportunity costs. A recent study by Naci et al. (2025) applies this rationale to the investment in new drugs compared to financing other traditional treatments. The results for the U.K between 2000 and 2020 revealed that the „quality-adjusted life-years (QALYs)“ is not in favor of the investment in new drugs. The relatively small numbers of beneficiaries of the new drugs is compared to the many other persons who could have benefited from the less costly previous treatment. Investment in one new drug causes disinvestment in other ones. The overall balance for the UK turned out to be negative. Particularly the disinvestment in prevention of diseases appears to have very detrimental effects in view of the results based on this study. Preventative measures are relatively cheap compared to the estimated 20.000 pounds for one additional quality adjusted year of life for a new drug. The message is: choose your health investments wisely to avoid ever rising health costs and health insurance. (Image: rest room Belgium) 
Animal Longevity
- From time to time it is interesting to study animals from many species to maybe learn from them about longevity. Roberto Salguero-Gómez (LINK) developed a sociality continuum and compared 152 species across 13 taxonomic classes. The study reiterates and generalizes the many studies of single species and finds that „more social species live longer, have more generation time and longer reproductive windows“. Social structures amongst animals of the same species influence survival and reproduction as basic demographic processes. These processes determine to a large extent the size of animal populations. Sociality appears to be a major contributor to longevity compared across species. These processes determine the survival of rather solitary species like panda bears (running higher risks of extinction) compared to populations of bees with rather hierarchical predefined social structures. The spotted hyenas developed cooperative hunting and communal care which allows for effective survival compared to other species. Sociality is specific to species and therefore largely determined by genetic factors. Nature rather than nurture is at work. However, species where reproduction occurs later allow for learning curves of sociality. In other words even within species there is scope to improve longevity through sociality. Migration patterns or experience with migration might be yet another determinant of survival or longevity as climate change poses new challenges to many species.
No tobacco Sweden
Sweden is the forerunner as country with the lowest number of smokers across Europe and probably even the world with only 5% of the population 16 years and older. The success of these public health policies is due to banning smoking not only form pubs and restaurants, but also outside in the surroundings of public spaces like schools, playgrounds, train stations and sports facilities. These policies work quite well and the effects of discouraging smoking in public is reduced to a minimum rather than the normal encounter.
Health of the other persons and children passing through these areas is not the only goal. A new estimate of lost days or years due to smoking based on a study from England shows that “each cigarette smoked reduces the smoker’s life by about 20 minutes (17 for men, 22 for women, LINK to study). Of course, there is a huge variance and other work and life conditions that play an important role as well, but the broad average estimate is a nice way of talking about statistics. The basis of the estimate is for those who stop smoking and not those reducing their tobacco intake by some percentage or replacement product.
In the Belgian football stadium (image below 2024) in Brussels the No tobacco sign is well placed to make parents of children and youth understand the challenge ahead. Good resolutions are assisted by gentle regular reminders as well. 
EU Georgia
It is a moving image to see a hundred demonstrators at „Unter den Linden“ in Berlin just next to the Russian Embassy. The Georgian flag and Georgian people actively seek the association with the European Union and the values it stands for. Irrespective of a large majority of the people of Georgia‘s wish to become part of the EU they have to fight hard to be heard. Next to the Ukranian protests in Berlin it becomes very evident that these two nations fight for living standards and values which are so „self-evident“ for us European citizens that it is all to easy to forget about our neighbors who have to endure hardships with uncertain outcomes. The experience of having lived together under one roof with people from other countries allows to realize that we have so much more in common than what separates us. Our house and home of the EU has much to offer, more than we tend to believe in our daily routine. 
Happy Year
- Happy Past Year? Happy New Year! Happiness is the driving force behind most endeavors for all people beyond the needs of subsistence. Even if many believe that money makes the world go round, the thrive for happiness is soon overriding the comparatively simple pleasures money can buy. A Bistro in Berlin in the middle of a park has the entry reception entitled „zum Glück“. An excellent wish for the New Year and a chance to review the „glückliche Momente“, the happy moments of last year.
Career Criminals
From a life course perspective it is not easy to define a colloquial term like career criminal. A person who has been convicted for a single crime and has served his/her sentence should be allowed full integration into society. Even a repeated offender should not be stigmatized or labeled as career criminal. However, this is exactly what the NS-state did (traveling exhibition across Germany and Austria: „Die Verleugneten“). These persons were subject to targeted charges for criminal offenses they „might“ commit eventually. The term „community alien“ or „asocial“ were also used to refer to persons that did not fit into the dominant Nazi doctrine of „Volk“. It took 75 years until these persons could receive a recognition and a recompense for their unfounded discrimination and incarceration. In concentration camps the so-called asocial or career criminals were at the highest risk of further prosecution and death. Great that the stumbling Stones include these victims as well, as a way to remember these crimes against humanity. Beware of definitions of social groups which are based on totalitarian ideologies. 
Zerreissprobe
The term „Zerreissprobe“ has been chosen by the curator team of the Neue Nationalgalerie In Berlin for the Retrospective of „Art between politics and society“ in the years 1945-2000. In this time period after the 2nd World War until the other „fin du siècle“ the politics of creating a new world order, the cold war and the liberalization of societies had profound impacts on art as well. The positioning of art in the dynamic context and conflicts of these decades is quite well reflected in the title of the exhibition. The English title „extreme tension“ suggests somehow that these years were rather extreme compared to ?, probably today? Although on the territory of Ukraine we witness a hot war rather than a cold war initiated by Putin‘s Russian imperial illusions. The cited work of Günter Brus „Zerreissprobe“ is translated as „stress test“. And maybe, this translation characterizes the post war period even better as these years are a forerunner of what happened after 2000. We continue to be put to tests in politics and societal developments. Accomplishments from the last century are put to crude tests again. Solidarity of people and nations are under pressure to demonstrate their reliability under extreme tension or stress. Art throughout the 5 decades of the last century was a precursor of stress tests for politicians and challenged society in its basic understandings. The comments on the notice board next to the exhibition show the themes of tension in the 2020s. Tensions in families and partnerships, often more extreme around christmas trees, have taken center stage for younger visitors of the exhibition. Sociological research has observed such trends and coined this societal phenomenon „individualization“. Art embedded in society seems to be part of that evolution as well. Art movements are less visible as collective movements. Artists appear more individualistic or ideosyncratic nowadays, just less inclined to be part of a defining larger group. If artists are no longer avantgarde but rather followers of societal trends, the whole „raison d‘être“ of art changes as well. We are likely to witness yet another „ Zerreissprobe“. Cuts to art and culture budgets constitute an additional „ Zerreissprobe“ in the original sense of the word and of art between politics and society in 2024/2025. 
Films of Stills
The exhibition of multimedia artist Nan Goldin at the Neue Nationalgalerie (New National Gallery) in Berlin presents a retrospective of her work using slideshows of stills including soundtracks (Image below). The topics and narratives range from autobiographical work on own traumatic experiences to works entitled „memory lost“. The sequences of stills are a form to deal with trauma through art like overcoming the suicide of a family member. Drug or sexual dependency enter the stills and it becomes clear that stillness is part of the coping mechanism she employs. It is hard to watch, sit still and endure the films of stills. However, there is a kind of therapeutic experience to be gained in coping with trauma through art. The installation in several tents increases the reclusive atmosphere and entering the still rooms invites is, somehow including a warning of what kind of chilling experience we are up to throughout the exhibition. The almost therapeutic experience needs to be handled with care and a visit with friends or family is highly recommended in my view. Community and communication are key to coping with these experiences and even still images contribute to building resilience. 
Cumulative Mandates
Since 2010 and with 18 volumes the documentation of perpetrators assistants free riders during the Nazi rule in Germany has been valuable and reliable source of information (Kugelberg Verlag). The book series defines the perpetrators as the persons excuting crimes themselves or were in command of those who committed the crimes or gave orders to do so. It is not surprising to find evidence of many crimes, but rather that it took such a long time until the documents were published and the descendants were confronted with the facts and the difficult heritage. There are still many who undertake all efforts to deny the facts or try to minimize the guilt of perpetrators. With the real dangers of new right-wing extremism on the rise across Europe and even beyond, it becomes more important to uncover the strategies and biographies of the perpetrators. Certainly the members of the SS were executives and in command of atrocities, so-called NSDAP party officials were also mostly convinced followers of Nazi doctrines and instrumental in the implementation of crimes. Additionally, several professions (line soldiers or medical doctors) were key in the process to ensure the power of the totalitarian regime until the final days. Some persons were cumulating roles and became thereby inescapable spiders in a web of control and crimes. The lessons for today consist in hindering excessive cumulation of mandates, political, professional, military and in other work or civil society related functions. Distribution of power is one form to safeguard the survival of democratic structures. 
Conducter Careers
The careers of conductors during the 1930s and 1940s have been propelled by joining the NSDAP on Germany. Even if not too outspoken as conductors on Nazi discriminatory policies many openings arose only due to banning Jewish conductors and musicians from performing in public. The acceptance of vacancies due to such restrictions advanced the careers of Karl Böhm as well as Herbert von Karajan. A theatre play Böhm at the Deutsches Theater in Berlin takes up this topic and puts the professional career in perspective of an anti-humanist leadership style. Karajan has also come into critic, because of his role in selecting musicians who were conform to the prevailing Nazi-antisemitism. It is important to work on these biographies and their implications for hundreds of lives of other musicians. Many careers have been destroyed due to these two prominent conductors ready to do almost anything to advance their careers. It puts their interpretation of music in a different light knowing about their instrumentalist approach to music, their own careers and the disrespectful Nazi doctrines.

Victim Perpetrator
Research on the Shoa and the Nazi crimes has a clear cut separation into millions of victims and millions of perpetrators. There is only a very small group of persons who risked their lives in their attributed or chosen role of perpetrators and saved lives. Most of those persons received recognition later, some decades later. The vast majority of persons were oblivious to their prior roles and some even tried to defend them themselves through a variant of victim blaming in recurrent attempts to reduce their guilt. Another frequent excuse is to recur to a perpetrator’s own experience as a victim of abuse or tough childhood. In a static perspective this might work, but the learning and reflection ability of humans apply to all persons irrespective of age, if they show the willingness to do so. victimization is powerful tool to justify a role as perpetrator later on. Criminal courts assisted by psychologists statements accept guilt reduction. After all those considerations the basic classification into victim or perpetrator remains a valid differentiation, only very few cases allow for a more nuanced assessment of the case.

Sociology in Art
Sociologists study and teach a lot about social capital. James Coleman and Pierre Bourdieu each have coined social capital as a major foundation of societies. Therefore, the exhibition of the artist Rirkrit Tiravanija “happiness is not always fun” in the Martin Gropius Bau (Image below) is interesting beyond a justification art for art’s sake.
What does Tiravanija tell us about happiness and social capital we did not know before? The artist went to a Chicago based art school, hence, it is likely that he has been confronted with the concept of “social capital” by Chicago sociologist James Coleman. The Berlin exhibition of Tiravanija can be walked along and experienced through the lens of the creation of social capital as a form of art. Art raises awareness to the importance of social capital for the ways we live together and form communities. The Berlin exhibition, meeting place or play ground is worth multiple visits as the participatory experience changes each time. In each of the rooms we reflect on our cultural practices like sports, music, printing or cooking as forms to create community. Each time we take home a little bit of social capital as well. “Happiness is not always fun”, but for sure You’ll have many happy moments throughout the visit of the exhibition. The guided tour by curator Yasmil Raymond (2024-12-19) added yet another little bit of spice to the exhibits. For a few moments we felt like a strong link between Chicago and Berlin, just like those sociologists in Berlin who studied and continue to study James Colemen’s foundations of social theory.
Reconciliation
European history is a long history of atrocities committed against humanity. The Documentation Centre for Displacement, Expulsion, Reconciliation in Berlin (Image below) captures this history in a comprehensive manner. We are quickly overwhelmed by this weight of history and the implications this has for the understanding of the people on the globe. This relatively new learning centre has, beyond the memorable permanent and temporary exhibitions, a room of silence to recover from the hard work of remembrance, always in view of reconciliation.
The library allows personal search and research of migration documents and biographies. All centuries have their history of displacements, but the Nazi terror surpassed all prior records and forced millions into displacement or death. We are still working on this heritage and the enlightenment of how these atrocities could take place. Full consciousness of the terror and horror of the 30s and 40s is necessary to guard against the many attempts to falsify historical events or discard the sorrow of millions of people and their families.
Reconciliation remains a continuous challenge. A large part of diplomacy has to deal with reconciliation beyond concerns of daily affairs. It is not just a matter for head of states and days-off during a year. Stillness helps to deal with the challenge, especially if it is very difficult to find adequate words. 
Kids Space
Political claims to reserve more space for kids in cities have a tough time. Kindergardens or child care in general are scarce and the lobby for kids is often limited in time and extent, since it is the parents that usually are the ones to advocate while their children are small. Jointly parents and children of young age experience the tough atmosphere to find, preserve or extend the space for kids.
The Gropius Bau in Berlin has opened up an exhibition space reserved to children 3+ as part of an art project “BauBau” designed by Kertin Brätsch 2024. A colorful room and installations as “loose parts” are the starting point to delve into a real/fantastic world were kids reign. There are a few so-called “playworkers”, who accompany the endeavours, if need be. At the end of the day the room was still in pretty good shape I would say assuming that “children set the tone and decide what happens in this place”. Safe and supportive environments for children are scarce and parents are always challenges in their attention to watch out for risks of all sorts in public city spaces.
Even if the “play space” is free of charge, it takes parents or kindergarden managers to reserve the space.
An early experience of a museum from the inside is likely to have lasting effects on children and the parents. They might have fond memories of a museum as an exciting space also for them. It constitutes a nice continuation of the outdoor “radical playground” project during summer 2024.
Health Tech
Health technology assessment (HTA) is an interesting scientific field. The new digital opportunities allow people to participate in medical and medication trials in their homes or even in bed. Their health data and the administration of medication is also encouraged and sometimes supported through digital devices. The pharma and health industries have many devices ready to go. The differences to the traditional forms of medical trials, however, is an issue as we want to compare the results from both kinds of trials. Participants of trials, might prefer or struggle with these novel kinds of study designs. In any case the results will be impacted in several forms (Study Link). In the best of all worlds for the researcher the effects will cancel out each other, but is rather unlikely. Some participants will reach more positive effects with the use of digital tools, whereas others are challenged and might even abandon during the trial. Monitoring during the study (for example through digital inhalors) is another advantage of such distributed trials. Rather than taking adherence to a trial medication for granted, digital tools allow a more precise monitoring of subgroups as well. Data and effort invested in the trial is preserved through the easier access to person’s information, assuming continuous readiness to stay on in the trial.
Our own smartphones are still underexploited in terms of health monitoring and use in research designs. The possibilities to link data to other external data sources shall further advance the research potentials in many interesting ways. Data protection and data security become even more important with the ever smarter phones and connected devices.
Health data
2025 will be a crucial year for health data across the EU. Germany introduced the electronic patient card, which can store basic information to then access data in the health insurance cloud for medical doctors, hospitals and other related health services. Potentially this is a great step ahead as some tests do not have to be repeated if they had been completed recently before already.
In pseudomised form, research may draw samples from such databases to enhance our science based understanding of disease. The evaluation of public health interventions becomes easier and medium and long term efficiency of measures can be assessed in many instances.
The Belgian research using health data has met to discuss the potential and limitations to link health data to other data sources to allow more complete and more complex analyses of health and disease processes. Another extensive data source sits on our smartphone. Collection of steps walked, sleep patterns or heart beats give valuable insights into a person’s own contribution and care about personal health. Although data are frequently incomplete, researchers are used to estimate missing data on the basis of existing or comparable person’s data. The basis for improving health for all are quite promising, data handling and linking them will be a challenge to the competence of all stakeholders and everyone involved in better health. It will be stressful before it becomes a routine. 
String Quartets
There is a plural form of Quartet. Philip Glass has composed a piece for 3 string quartets. Thanks to the Kronos Quartet performing and celebrating in Brussels, modern compositions are continuously added to the repertoire written for and performed by string quartets. Contrary to received wisdom the tradition of string quartets is still alive and kicking. At Bozar (Brussels) the marathon performance of 27 quartets, not all at once, but spread over a day and several locations, afforded a great free-of-charge opportunity to wipe off the dust from the sometimes rather introverted form of string quartets. Despite the high share of young musicians who performed well at the occasion, the afternoon focused more on new compositions. Concerning the audience, however, there is still an older age bias in listeners, more the standard Bozar clientele so far.
The afternoon reminded me on listening CDs entitled: “I don’t like classic music, but this one I do”. Many people came for art exhibitions at Bozar, but then (re-)discovered on the sideline the atmosphere of chamber music at this occasion. Closing the age and social gap in classical music is quite a challenge. It is surely more like a marathon than just a few sprints here and there. The new format at Bozar in cooperation with the Kronos Fifty for the Future Marathon will sooner or later find extended audiences beyond the happy few this time. I would recommend listening to string quartet music more often until the “Transcranial direct current stimulation (tDCS)” will be the new hype. 
Book Annotation
For most people book annotations are considered a nuisance. However, most pupils or students mark their so-called textbooks, which contain many images nowadays anyway. A good mindmap, summary of text, highlighting or critical comments may be part of their day-to-day working with a book. Some editors facilitate this using broad margins and more space between lines. Working through a text can take multiple forms and books have allowed over centuries different kinds of their usage.
There is yet another underexplored usage of books. On printed volumes annotations of previous readers may serve as a guide to a script of places, thoughts or material of particular importance. I have always found annotated copies of other readers interesting in their own right. Reading an annotated copy felt like reading another person’s mind, thought or learning process.
A modern view of books as a tool of communication might extend this perspective to study annotations of several readers on the same copy. Just like we comment today in word processing on texts from collaborators or students. Books are a means of communicating with other people or machines (AI) usually with the aim of spreading ideas, content, horror or pleasure.
Therefore, I am always happy to find annotated versions of a book, especially of prominent authors. It sometimes feels like reading a “partition”, a transcript of music which contains the comments or fingering of the reader or the performing musician. The BNF has a lot of such special copies in its archives, usually found in the donations of persons or prominent authors and their families to the archives. This can be put together to make an interesting exhibition of the process of thinking and writing and of special treasures – annotated books.

Shorter is better
Contrary to a lot of received previous recommendations, the shorter duration of antibiotics prescription and use (3-5) days is overall better than the prolonged use of durations between 7-14 days (JAMA Link). A so-called narrative review of medical studies (Lee et al.2023) reports more precise results separate for medical indications (pneumonia, sinusitis etc.), which tend to go in the same direction for the majority of indications. In view of the serious issue of antimicrobial resistance, a consequence of overconsumption and too widespread use of antibiotics (also in animal health and food production), the slogan of shorter is better should receive serious attention.
It is not only a medical, pharmaceutical or public health issue. The topic has become an issue of nutrition as well. The food chain contains largely unknown amounts of antibiotics as well, especially if larger amounts of animal or fish products are part of it.
The knowledge from these sciences has still to filter through to the broader public. This means it has become a social science topic as well. The transmission of knowledge and patient expectations on prescriptions, which is also linked to regulations concerning sick leave, make it more difficult to shorten prescriptions of antibiotics. There is a steep challenge to change behaviour according to the new mantra “shorter is better” with respect to antibiotics, even if we know that it is better for all of us in the medium or long term.

Sexual harassment
Under the broader topic of violence against women, we count gender-based harassment at work. The recent report of a survey based on more than 100.000 persons in the European Union in 2021 shows the shocking amount of violence in the last 12 months as well as violence experienced over a lifetime. (Source Eurostat Link to pdf report) These data have to be interpreted with care since it is a well known statistical phenomenon that in some countries such misbehavior is reported and talked about more easily and openly than in other countries. Therefore, the countries with the highest figures, for example in Nordic countries, there it is safe to talk about the issue (Nordic paradox), whereas in other countries violence against women and sexual harassment at work are still much less talked about and addressed in public. Italy even deviated from the joint EU data collection.
It is important to address the topic in the media and lift the cover-up attempts in many societies. This is a process over time, but it is important to continuously raise awareness about the problem. We have made a lot of progress on more equal treatment of women in recent years in most European societies. However, the is need for a “zero tolerance” of violence against women and the sexual harassment at work, which prevents women to take equal shares across all professions. Monitoring the process is an important step, which is necessary to target safety measures in a better way. Further details of the statistics are needed as well to address intersectionality as well. Young women tend to suffer more than older ones. Maybe the latter ones have learned to be more careful to avoid or evade critical situations. It is, however, men who have to reconsider their behaviour towards women at every age, at work as well as at home. 
Mind Paris
I have been asking myself what it may mean “to be in a Paris state of mind”. After a creative sabbatical spent around and about Paris I am happy to present the flipbook of entries on Paris in 2024 and the Olympic Games. My perspective is a social scientist’s view of public affairs. It builds on the many brillant minds and organizers who managed to make Paris a very special experience in 2024. Beyond the fabulous distraction of the sports events, which received sufficient attention, there were and there are so many exciting experiences that it is well worth speaking of a “Paris state of mind”. It happens in the quiet places of Paris, the museums, libraries, churches, parks and in the pedestrian areas. The 21st century has begun and Paris wants to remain in the top locations for modern experiences.
My flipbook for you to enjoy: Paris and Olympics 2024.
also as versions: size 16 MB Pdf-Version, best to read in even spread format over two pages on one larger screen (text left side, image right side), just as a suggestion.
Some prefer already the epub3 format (EPUB3) to jump from topic to topic and follow links in a comfortable way, but please do not print to save paper. THANKS, feedback welcome. 
On Keys
Keys may open multiple doors. Even a single key can open many locks, if constructed in the appropriate way. The obverse of key is also key, at least in the function of keys to lock doors. Hence the trick of the key is its dialectic function (open/close) of access. We practice the functioning of this binary thinking (1= open, 0= closed) several times a day. Even binary thinking can become very complex in case you consider a bunch of keys or organized as a ring of keys. With a plurality of locations or rooms (home, work, leisure) the uncertainty to have the fitting key to the lock in question at your disposable becomes a bit of a puzzle. Here we are, trial and error enter the stage for most of us. Don’t worry, there are digital tools to solve the problem for you, but then the whole issue of trust comes into play more forcefully. Sharing is not only caring, but also daring. Transponders replace keys and passwords have become the new “passe partout”. This leads to the brave new world of encryption as the keyfactor for security. Encryption is key. Are you already encrypting or still turning keys?
Keys are key to understanding as well. Artists in Berlin-Schöneberg combined the portraits of persons and their bundles of keys next to each other. Keys seem to reveal key personality traits of a person. Life course researchers may investigate the “first ownership” of a key to a room, an apartment or the family home as a factor of independence, even freedom to move. Handing over the keys of a car or your home to a significant other may mark looming restrictions due to health issues.
Anyway, what is your favourite key in music? More a fan of serial music or 12-tone music?
