Swimming Paris

Swimmingpools are rarely on the to-do-list of tourists in Paris. This is good news for all those who go to a Swimmingpool for real exercise. In Paris you can enjoy the almost a century old public pool for swimming exercises with 50m lengths. In the entry hall you have literally a hundred doors where you change and, previously, you kept your clothes while swimming. Light by design welcomes you to do something good for you, physically and mentally. The “Piscine Blomet” (Paris 15th arrondisement) preserves a bit of the charm of the early 1930s Art-deco style in Paris. Sports deserved to be performed and exercised in fine architecture not just functional concrete. It is quite a challenge to preserve such architectural treasures including their original function. It is not all just business and tourism in Paris.

Healthy intervention

The shift back from a city which favors mobility on wheels to a city where more people move using on their feet is healthy intervention. Paris has succeeded in many inner city areas to improve the „walkability“. On Sundays joggers pass in groups where previously cars were rushing across the city. Noise levels and pollution have been reduced which attracts even more tourists. Many more than the city could handle with too much space occupied by cars and trucks. Security levels are increased by restrictions to car access to some roads and people feel safe and relaxed even in the city center of a metropolitan city. Besides the effect that more tourists come to enjoy this atmosphere, those living and working in Paris feel less forced to leave the city over weekends due to unhealthy pollution levels. Access from suburbs by public transport runs at high frequencies also on weekends. This brings people into the center for events, shopping and event shopping.

Paris Room with a view

The home of Victor Hugo in Paris offers a splendid view of the Place des Vosges. The image taken from the 1st floor of the building and his living room allows to see a bit like what Hugo saw every day for some time. A small park, probably a lively street with arcades full of shops and people. Lots of inspiration and observation which may come from actual life. The actual time of writing, however, needs also retreat from the busy daily surroundings to focus one’s mind. All this hasn’t changed since Hugo lived in Paris at this address. Writer in residence programs of today allow authors to focus on their work beyond daily tasks. Cultural advances heavily rely on such programs nowadays to be able to have at least temporarily “A room with a view”.

Fleeting memories

Our memory function is challenged once we travel. There are so many new impressions that ask for prime time in memory, but our capacities to safely store every detail of it is rather limited. On his voluntary travels, less when going into exile, Victor Hugo drew places with astonishing architectural detail and made literary descriptions on the back of the copy. The ruins of a gothic church in Bacharach (Germany) on the banks of the Rhine are a great example of his attempts to beat the fleeting memory. The ink and graphite pencil drawing date back to 1840. The imagery of the abandoned church, itself rich in memories of conflict by way of drawing details inscribes deeply into his own memory. A description in words on the back of this piece reinforces this effect beyond the mental exercise of precision versus dramatic blurriness. Repeating this exercise months later would reveal our fleeting memories when traveling. A great technique which is still valuable 186 years later.

Hugo voyage

Victor Hugo traveled for inspiration to neighboring countries. He has been attracted to o mysterious places and its people. In his booklets of such inspirational journeys he drew images of several architecturally interesting places. “Burg” meaning castle was a recurrent subject trying to capture the mysteries about such medieval places and their surroundings. The rivers “Rhein”,”Nahe” and “Mosel” in Germany were a great source of inspiration for him. The images drawn of “Burg Eltz” as well as others (Andernach from 1840, image below left) testify to this. The Home of Victor Hugo in Paris, Place des Vosges features in 2026-8 his drawings which seem to have served him as studies in architecture and sometimes as idea of maybe a scenery for his theatre pieces. Of course, his drawings of cathedrals similar to “Notre Dame” in Paris are also among those ink sketches. To get scared a bit, traveling might suffice and then write it down and sketch it. Franco-German influences can be found in many European artists of the 19th century as well as today.

Gone sailing

There are numerous ways to spend a nice vacation and take off your mind from daily routines. Sailing is certainly one of those leisure activities which ask for full concentration. Steady winds are more the exception than the rule and the skipper is asked to adapt rapidly to changing wind directions and other conditions. Waves and other sailing boats may of course ask you additionally to adapt your course to unforeseen circumstances. All this is a great training to keep on track even in stormy weather conditions around you. Team work helps to set sails as well as in manoeuvers to enter into ports. The Paris Jardin de Luxembourg (image below) allows training of parts of these competencies from an early age on and into old age as well. The physics of power and capsizing are part and parcel of sailing as well just as much as rules for crossing course, of course. 

Activity and dementia

In view of the huge challenge of dementia to people and the public health systems, it is primordial to test potential remedies with high precision. So far general measures of just any physical activity like walking were considered beneficial. Recent and more comprehensive data on domain-specific physical activities by Feter et al. (2026) emphasize the importance to differentiate between walking for leisure or walking rather stressed to work. The former contributes to a delay of the onset of dementia, whereas the latter bears higher risks of dementia due to the “negative” stress involved. However, as Kivimäki and Hamer (2026) point out dementia itself has a long gestation period in which persons might reduce physical activities because a “silent” onset of dementia is not yet diagnosed but inhibits already more activities. Commuting to work or leisure might already be a challenge in early dementia particularly if public transport has to be organized independently.

Painter influencer

In modern terminology we could say Edgar Degas has been an influencer for many other painters, gallerists, art collectors and our way to look and interpret paintings or drawings. Max Liebermann wrote an appreciation of the work of Degas for a German audience in an attempt to bridge the gaps in the understanding of modern art between France and Germany towards the end of the 19th century. Cassirer as editors facilitated the publication and jointly they achieved to build a remarkable collection of impressionism before the atrocities of war took over in the first half of the 20th century. Fates can change quickly and painter influencer may become discredited due to more forceful political influences. (Image: Booklet by Max Liebermann 1898 on Degas in Cassirer exhibition in Berlin)

Sleepless sleep

The reasons why we pass an almost sleepless night or sleep are manifold. Too much to drink, eat or partying are just among the more social ones. The neighbour’s cat or cock may be another one. A recent comment by Pixin Gong (2026) outlined a whole research agenda on heat and sleep deficits. What is the threshold of bad sleep? Do we accumulate over days and how do we recover from it? Which measures and metrics are important? How to determine the social gradient of sleep deficits? The research base is largely missing due to neglecting the link of temperature as crucial impact on sleep in addition to melatonin levels. The implications of expected results can be far reaching like re-organization of homes, urban planning and architecture.

Outdoor Pleasures

Summertime surely is time for outdoor activities and pleasures. Besides the broad spectrum of more or less strenuous activities, summer is perfect for socializing in parks, restaurants, cafes or beer gardens. We might think of this as more recent inventions, but in historical depictions by Bruegel or Jan Steen (1661 in Gemäldegalerie Berlin, extract below) we find evidence that socializing in a restaurant or beer garden has been around for more than 460  years. Monks were brewing beer and the consumption was reserved to a more elitist group of people. The concept is quite old. Fortunately, we have managed to democratize the joyful and socializing part of being together.  Places where people from different social classes come together have always been rare and this, additionally, varies across regions, countries and often social strata.

Co-evolution process

Humans look back on a long co-evolution process with viruses, bacteria, insects and animals. The focus on a solitary evolution of humans alone is already a challenge, although we know that the evolutionary process is much more complex. Within the co-evolution process of humans and animals, the co-evolution with the species of dogs has lead to interesting learning opportunities for both. Braeuer et al (2024) show that a dog’s cognitive capabilities to perceive human emotions beyond simple positive or negative emotions. As dogs seem to monitor their owners constantly, many of them are able to alert persons about health and/or emotional state. This is a learning process for dogs, but also for their human owners as their authentic emotional expressions are immediately recognized by their dog. A co-evolutionary approach offers a lot of benefits to all involved. 

Heat Mortality

Heat waves can be deadly for humans, animals and vegetation. According to the cumulative estimates by the RKI (Robert Koch Institute) in Germany up until 2026-7-26 there were 11.900 deaths within the confidence interval between 10.700 to 13.100 of the estimates. About 6.000 of the people who died due to the heat waves were aged 85+. 1.140 were attributed to persons younger than 65. Chronological age appears to be a significant factor as frequently chronic diseases accumulate in older individuals as well as poly-pharmacy. Hydration levels and deficiencies are associated with the increased mortality, but we have few or no precise measures of hydration readily available for people before it becomes an emergency (cognitive impairments). We know a lot about precision medicine. However, precision hydration for people remains rather arbitrary.

Fountain of youth

The fountain of youth is such an old dream of humans that we are no longer surprised to witness perpetual reincarnations of the same theme again and again. The painting by Cranach the elder (1646) “Fountain of youth” (image below, Gemäldegalerie Berlin) sets the scene for what has become a billion dollar business nowadays. Whereas the old dream was about rejuvenation and cure from disabling diseases, we have become a bit more moderate in ambition to be happy about a halt to aging. Promises are reiterated and made in building on an army of influencers who push many remedies that lack rigorous scientific tests. Two studies published open access in “The Lancet Healthy Longevity” (Witham, McDonald 2026 and Duremdes Nava et al. 2026) provide evidence that in case of obesity and diabetes there are no easy or quick fixes available yet. Healthy longevity still relies mainly on lifestyle (changes), more exercise and careful nutrition rather than additional medication. Medium and long-term consequences of inactivity and unhealthy diets are to easily disregarded or their value discounted. How much are you willing to pay for an additional year of healthy living at age 30 or 70? Simple economics, but quite a successful business model as well.

Medication adherence

In the broad range of medico-pharmaceutical science the topic of medication adherence is an uncomfortable issue. In the ideal scenario people would adhere 100% to the prescription. In the real world of not-optimal behavior and circumstances, people deviate substantially from what is best for or even good for them. Even in the tax-based health system of Denmark with relatively easy access to medication, a long-term study revealed the difficulties encountered to adhere to essential medications for persons with Type 2 diabetes. Nielsen et al. (2026) analyzed a cohort of 80.000 persons who newly acquired Type 2 diabetes of which about 25% showed a low adherence to medication plans with hazard rate of 1,27 to suffer a cardiovascular event. High adherence persons did not suffer such an event in the following 220 days over the 10 years of observation. A sedentary lifestyle or obesity increase the risk of type 2 diabetes and beyond medical treatments additional behavioral challenges like medication adherence make it clear, we do not live in the best scenario to fight type 2 diabetes.

Social learning

The process and mechanisms that drive social learning are still not well understood. Beyond social psychology and sociological theory and evidence, neuroscience has made progress worth taking note of. The paper by Maciej Winiarski et al. (2025) offers a key insight into the neuro-biology of learning about social structures and the behavioral consequences. In their study of mice in the EcoHAB supervised group housing, information sharing through scent was the driver of learning about the social structure and the ensuing social behavior. The various experimental settings show that 1-2 mice became the most relevant informants about social structure and rewards. The “exploratory activities” are an interesting underlying parameter as well. The mus musculus model does not tell us much about humans yet, but we get a gist of important factors to consider for social learning in groups or organizations. Information seeking, informants, reward structures and “housing” have to be considered based on such research from neuroscience.

Road injuries

Road injuries are a serious matter. The lives lost and people suffering from lasting injuries continue to be a major health hazard on a global scale despite significant reductions over the last 3 decades, mainly in wealthier countries . The Global Burden of Disease study (Ng et al. 2026) shows that between the ages of 10-39 fatal road injuries are the main cause of death for young men. The study has no data to speak to causal effects, but the basic statistics show a clear pattern according to gender. Several factors need further exploration:
1. Men are known to have a much larger share of the total amount of road traffic in most countries, which leads to a higher risk exposure.
2. Men seem to take higher risks when driving, which puts them at higher overall risks as well.
3. Responsibilities for road incidents are not investigated, which leaves other causes or contributions to road injuries (like alcohol or drug abuse) unaccounted. (Source: Ng et al 2026. Global, regional, and national burden of road injuries 1990–2023, p.7)

Cardiac arrest detection

The number 1 cause of death is cardiac arrest in the modern world. Hence, the interest in the detection of cardiac arrest could save many lives. For assistance to arrive and intervene in time an alert needs to be issued as soon as possible. With early detection by nearby persons and skilled intervention the survival chances are about 50% of cases. The “silent” at home cardiac arrest is an important health and survival issue. The availability of wrist bands and watches which can issue alerts in combination with smartphones has risen considerably in recent years. Therefore, the improvement of reliable algorithms which interpret these data can realistically save lives as the delays can potentially be shortened for professional helpers to arrive. The study by Edgar et al. (2026) tested such a device and were able to show the very low number of false alarms issued by this device (about 1 out of 40). Extrapolated to millions of cases the challenge to a health care system is steep. However, we have to deal with such socio-economic issues of digital devices in medicine in the coming years more often.

Inclusive design

In aging societies inclusive design is not an option but a must have. This is neither a short term fix nor a renovation without costs. Adapting a home to a wheelchair use is an expert job as you have to think about issues you have not experienced yourself before in most cases. Door thresholds and openings, better have sliding doors as much as possible, have to be considered early. Bathroom adaptation in size and height, toilet space and lighting switches all should be planned ahead. There exists a DIN Norm 18040 which specifies measures precisely. In the age of AI-vibe coding some home appliances could be programmed to follow a person’s voice commands as well. For the time being in 2026-7 this is a nice to have option. but early installations of “intelligent digital devices” beyond a washing machine or microwave can get you quite far in the near future. Inclusive design could open doors and switch on lights simply by talking to your smartphone.

Dancing alone

In 2026 it is possible to step into the old telephone box, but to use it as discotheque with music. You can choose your favorite song and dance to it inside the box and photos are taken from yourself to take home. Whereas sociologists have long argued that individualism can go to far in modern societies, the solo disco-box is a telling example of how monetizing of music, dancing and enjoying music can reach levels where people no longer realize how far we have gone beyond „bowling alone“. We do social activities alone and then share the images of the pseudo social activity. Room for social or socializing activities does not come for free, but creating meeting spaces even in crowded cities is worthwhile. Dancing in public rather than a box might be enjoyable for others too.

Brussels relaxes

Especially during the weekends and the summer activities some roads can be blocked for other uses. The obese societies of the 21 century need to make room for more exercise wherever possible. Brussels has done so for more than 5 years already. The “Bois de la Cambre” offers an amazing space to all those seeking respite from the busy and warm urban surroundings (Image below). Children and families exercise all sorts of activities and sports. The closed roads are perfect for cycling and jogging as well as the learning of both. Levels of air pollution drop and the running sport is no health hazard as in inner cities. Each and everybody advances at her/his own rhythm (Video Weekend jogging in Bois de la Cambre on Road 2026) or just watches others passing by. Ways to relax in cities are manifold, in a matter of choice and commitment. Commit to relax and detox, at least on weekends. This can be quite a behavioral change with serious health benefits.

Berlin moves it

Yes, we like to move it. Investment in infrastructure follows a long-term economic rationale. In urban areas space is a scarce and, therefore, an expensive resource. In order to use the current space for mobility more efficiently, the use of a longer tram or train is an effective way to increase capacities. Rather than to increase the frequency, which is no longer possible without safety risks, a longer vehicle allows to bring more, and more diverse, passengers on board (kinderwagen and wheelchairs included).
It is a long-term objective to make urban areas liveable for all ages. Tramways which allow a low or, better, no barrier to entry is a necessary condition in this respect. The new “Urbanliner” in Berlin (image below) offers such essentials of access and urban mobility. A single tram is 50m long with 88 seats and 215 standing persons in larger corridors. 300 tram passengers can be compared to about 12 average length cars with at best 15-20 passengers.
A consensus of “how best to move it” in cities pays off in the long-term. Planning has to start about a decade before delivery and needs to survive political cycles going back and forth.

Learning locations

We tend to associate schools as the primary learning locations. However, there is a multitude of additional locations that offer excellent learning locations like museums, libraries, churches, enterprises or various associations. Some of these learning locations have better equipped learning facilities and environments than many schools. It is about time to reckon with this and advocate stronger links between the often disconnected worlds of learning. Teacher training focuses on schools, curricula and teaching methods, but the systematic combination of all these „external“ learning locations with the full-time schooling world could stimulate so much more learning. Maybe, even the social selectivity of education could be reduced through the motivation and different entry points into learning by a diversity of learning locations. Lifewide and lifelong learning are likely to be motivated at an early age. (Image: Stabi West-Berlin 2026-7)

Learning and authenticity

For historical, philosophical, social and many other domains, learning in authentic locations moves learners particularly. This can consist in reinforcement learning of an otherwise abstract event or process. The neuroscience of learning has demonstrated that both parts the rational mind and the emotional relatedness contribute to learning success. Memorials are such places where persons get involved with all their brain and senses. Robert Sigel (2015 pp.50-53) described the wealth of pedagogic approaches that has entered memorials. They range from flyers, guided tours to geo-caching, digital apps and continuous involvement in social media related to on-site visits. Memorials are no social-pedagogic institutions either. They cannot guard or even correct more or less likely antisocial social behavior of visitors. Additionally, they have to strike a balance between 360 degrees, engaged learning and decent commemoration. Authentic objects and information, like biographical accounts, original voices, videos or handwriting reinforce the lasting memory in and of  a memorable location ( Koessler, 2025 p. 79). School curricula make far too little use of this well implemented combination of learning and authenticity so far. Great potentials are ahead of us building on the specificity of each memorial. (Image: topography of terror, webpage access on site 2026).

Learning moral sentiments

In school curricula and evaluations of pupils learning progress there has been little attention to pupils’ learning moral sentiments. Religion and comparisons of religious practices have entered educational programs, but even the big PISA studies have largely refrained from evaluations of learning achievements in ethical matters or moral sentiments. Adam Smith as proponent of the Scottish enlightenment had written about “The theory of moral sentiments” before embedding his market economy into the enlightened society. In the 2020s we realize that we have neglected this part of learning for far too long. This is the point where memorials can play a primordial role as a central part of learning not only about history, but moral sentiments in the broadest sense. Memorials “Gedenkstätten” operate as quasi-schools” in this respect for young and experienced learners at the same time considered that more than 50% of learners in memorials pupils, students or from teaching professions. However, outcomes of  learning in memorials could also be assessed in order to check what kind of learning goals and moral sentiments can be addressed in such historically charged learning environments. Such learning locations of moral sentiments have to balance the intended learning with the necessary decency of the commemoration in such learning environments. (Image: Topography of terror Berlin exhibitions) 

All the lonely people

This line of a song by “The Beatles” dates back to 1966. “Ah, look at all the lonely people” is a kind of puzzled outcry to reckon with the loneliness even in busy and charitable places. 60 years later in 2026 we have whole ministries in some countries to deal with loneliness. It is not a niche problem. Tackling the problem needs to go beyond raising awareness. Loneliness occurs at all stages of the life course: children, adolescents, young adult, migrants, employees, single parents, care giving people, even within couples, seniors and very old persons. It is not restricted to urban or rural areas, but changes from one to another phase in a person’s life course carry the risk to encounter loneliness. It may well be only a temporary phase before new relationships can be established or previous contacts revived. There is a role to reach out to people who might be lonely for all of us. Public policies should be scrutinised on all levels whether they manage to break barriers or raise new ones for persons to feel lonely. In Berlin, the local level in each district is taking measures to facilitate informal meeting points open to all ages and walks of life. The “Wüstenrot foundation” sponsors many initiatives where public policies are short of funds. Projects enhance networks of people and organisations eager to assist “all these lonely people”, wherever they all come from.  (Image: Conference on loneliness at Berlin city hall Schöneberg 2026)

The next big challenge in medicine and public health seems to be the multiple long-term conditions. Many people do not suffer from just one medical condition, but several ones at the same time. Diabetes is one such condition which frequently comes along in combination with other conditions. The definition of Multiple long-term conditions comprises 2 and more conditions like cardiovascular, metabolic, respiratory or cancer, to name just a few of the more common ones. Our health and care systems are little prepared for adequate treatments as this involves a coordinated intervention and poly-pharmaceutical therapy. Changes in a single condition have repercussions in the condition and treatment. This makes adequate treatment a resourceful process with limited knowledge about the multiple interactions and intervening parameters. Add, for example, depression to any of the above mentioned conditions and the behavioral assumptions of correctly taking prescribed medication becomes a major issue for patients. The challenge for aging societies and societies with more people suffering from early onset of obesity and diabetes increases in the coming decades. There are several teams that address these challenges in research which gives hope to all those suffering already from Multiple long-term conditions.

Willingness to pay

The willingness to pay for a product by consumers can be easy to predict. During the June 2026 heat wave in Europe, earlier and more intense than ever before, many people went to retailers offering cooling systems or fans with a determination to buy. However, the retailers who had stocks available found themselves depleted rapidly. The physical urge to find a solution to cool down a hot apartments has pushed the willingness to pay to new heights for such systems. A kind of market failure occurred as too many (short-sighted) consumers wanted to buy a quick fix for a serious personal health-related issue. The widely observed shortage of supply of air-conditioners and fans raised considerable frustrations on all sides, missed turnover and substantial profits for the retailers and lack of physical cooling in a suddenly “overheated” market.
The increased willingness to pay might be redirected to other “greener” solutions to the heating problem, but they often entail behavioral changes. This bi-directional relationship between willingness to pay and (lack of) readiness for behavioral changes is a fundamental principle of behavioral economics and sociology.

Gone Gliding

The seaside resorts offer additional experiences to people beyond swimming. Gliding on the water or in waves is an affordable exercise for everyone. It  just needs a small board and off you go. Falls are a usual part of the exercise. Beware of them if you have any prior conditions. For the 50+ generations some regular prior falling exercises are a must. Youth has the advantage of sufficient power per kg of body weight to afford repeated falls. Water and sand soften the falls. The gliding experience, however, is a great compensation for the risks taken. Not for everyone, but early experiences in or beyond schools give pupils a head start on how to balance out yourself in specific situations. Spectators and the experience to be under observation might influence your performance for the better or worse. Balance is a rather complex experience combining body and mind coordination for all ages. 

École buissonnière

In 2026 the “École buissonnière“, the outdoor schooling has become a viable alternative to the schools that are overly hot during summer. But far beyond being an alternative out of necessity, schools as well as kindergardens adopt a form of schooling close to and in nature. It can be so much more than a simple interlude or excursion. Learning from nature is a precursor of bionics as well as compassion. After all nature offers ample examples of diversity and coping mechanisms. It is an option not only for learning purposes restricted to the young, but it is underexploited in continuous learning and lifewide experiences as well. There have been abuses also in history, most notably by Nazis in Germany for purposes of indoctrination. The learning opportunities to encourage a critical perspective of our modern, technology- and screen-dominated learning and life, are huge. They just need experienced guidance on the way of discovery, comparisons and collective experiences. Children open up and have fun, the more the pressure of classrooms is alleviated.  Learning about the importance of biodiversity from different angles is a very human value and includes our responsibility for other species.

Ensor Home

There are few artists who stayed in their home for almost all their life. James Ensor was a personality who was profoundly attached and continually attracted to his native city of Ostend. After a short and unsuccessful spell at the Brussels art academy, he returned to his parents’ home and due to a heritage from an uncle, he could live in a nearby house, which also served him as his atelier. Although I did not come across documents that showed he had traveled a lot, nowadays his art work is spread across the globe. The seaside resort of Ostend was a real tourist destination and, therefore, many famous people of the 1st half of the century passed by and met with Ensor there. Not only fellow artists, but also scientists like Albert Einstein. Critical minds and people searching beyond the trodden paths must have been attracted to him, a personality who dared to challenge conventional painting and techniques of his time. A reconstruction of his atelier and several animations give a lively modern touch to his work and living style. My take home message from the Ensor Home: The search for inspiration might be just around the corner.
