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 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.
Patient Capital
There is something cultural about capital. Different cultures use different narratives when they commonly talk about capital. In Western capitalist societies it is common practice to cite “capital is a fugitive dear”, meaning that people who command sizeable amounts of capital tend to flee places once they become to agitated, especially by politicians. The Eastern narrative surrounding capital is more focused on “patient capital”. The newspaper “China Daily” has more than 6.000 entries referring to this term. On 2024-9-26 (p.9) the Japenese economist Kazuyuki Motohashi praised the Japanese economic system and its specific form of patient capitalism as based on” long-term, stable investment, which enables companies to achieve sustainable growth in the long run”. The Chinese economy suffers as Western capitalism from excessive focus on short-term profit seeking and this causes huge market flucturations shifting quickly from shortages to oversupply and back again. Short-term rent seeking is driving whole industries into fluctuations that are hard to attenuate through other economic (fiscal and monetary) as well as labour market policies (training, re-locations, internal migration).
It is interesting to witness that recently in Germany an example of a bank that had benefited from a patient capital approach of the German government for more than a decade (Commerzbank) is now prone to a bit of a hostile takeover from another bank probably more interested in the short-term rent-seeking. After all, banking and the varieties of capitalism approach highlight that at the very heart of economic rationale there remains a little bit of a cultural twist to understand what is happening in international economics and competition.(Image: Musée Rodin Paris 2024, Le Penseur”)
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. 
Buzzing free
It is always a chance to be in a city that bans cars for some time from streets and bicycles and pedestrians can walk freely in the city. On September 22nd 2024 this is the case in Brussels. In addition, the public transport system allows people to buzz around the city free of charge. Of course this is an invitation to get to know areas of the city where you normally don’t take the time to visit or mix with people. The police used the time to teach children how to cycle in a city in all security and respecting basic rules despite the enthusiasm for speed or going round in circles. Unfortunately, this happens only one Sunday out of 52 in a year. It is just amazing how the feeling of safety on the road changes again. The level of noise and pollution drops to levels of the countryside. Buses and trams pass the city easily and most people get around faster than they do on other days of the year. It is a bit like a coordinated health intervention for the stressed urban survivors. This experience is a modest reminder of how nice it was in Paris during the Olympic Games 2024 when prioritizing mobility beyond cars haa been effectively implemented for several weeks.
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.
Lost Objects
Project yourself into the future more than a hundred years from today, maybe even more than a thousand years from today. Some archaeologists will work on the planet earth to uncover the story behind the disappearance of the once very advanced species of homo erectus. They start drilling near some of the mystical sites of this civilization, the cities where mass celebrations were held called Olympic Games. These archaeologists use huge drilling machines to take samples at previous Olympic sites and uncover the remains of the thought to be modern civilizations on earth. Amongst all these samples they find all sorts of artifacts and layers left over. Plastics and metal structures appear in the samples as well as other forms of „artificializations“, transformations of earth’s principal „natural“ raw materials. The inhabitants of earth apparently lost or destroyed the planet‘s capabilities of CO2 storage and eventually became extinct. After fighting for survival on another planet the archeological expedition on earth saved this block of the remains of a doomed civilization. All this is pure science fiction, yet the specimen sample is exposed on the roof of the futuristic Fondation Louis Vuitton building near the Jardin d‘Acclimatation in Neuilly sur Seine.

Paris Trees
Preparing metropolitan cities like Paris for the heating up of the globe due to climate change is a huge task. As early as 2020 Paris started an ambitious greening program. 170.000 new trees by 2026 in a densely populated city is a steep challenge. With 114.000 trees planted by 2024 as the Olympic athletes and spectators gathered in Paris the city is right on track. The 2 parks “bois de Boulogne et bois de Vincennes” have jointly 25.000 new or renewed trees. The cemeteries, for example “Père Lachaise” has received new cooling trees as well. Most trees, however, were planted along the notoriously hot and overcrowded “périphérique” with 50.000. Only with the use of a Colbert-like planning exercise and rigorous implementation against even some initial resistance, it is possible to achieve this result and the ultimate objective. Visitors of the Olympic Games already experienced the differences during the summer of 2024. Detailed planning by means of a “Bilan par arrondissement” facilitates monitoring of progress. Publishing the information is part of the communication strategy to keep citizens informed and engaged in this silent transformation for the benefit of inhabitants and visitors.

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)
