Dual Task Processing

Extensive research into dual task performance shows that training of 2 tasks simultaneously can indeed enhance performance. New research by Schubert et al. (2025) indicates that there latent and persistent bottlenecks to the brain’s processing of such dual tasks, let alone multi-tasking. Out of own anecdotal exercise with “object tracking and touch” (gaming on tablet) a learning effect arises. However, it is unclear, whether this exercise translates to normal traffic situations in inner city situations for pedestrians or cyclists. The experiment of a dual task, combining a visual-manual and an auditory-verbal task, indicates also training effects, but the brain appears to return to sequential processing rather than simultaneous processing as much as it can. Such a dual task test may consist in juggling while singing a song or even leading a conversation with somebody. Quite a challenge or exhausting mental training even for those with a history of juggling objects.

БЪЛГАРИЯ Bulgaria

The expectations of the entry of Bulgaria into the EURO-Zone are high towards the end of 2025. On the 1st of January 2026 we have new coins circulating in the Euro-countries. The addition of a country to the European currency yields insights into this country’s own cultural heritage. Piece by piece we learn, if we want to, to take a closer look into the more and more obsolete practice to handle currency in form of coins.
I cherish some of the coins with specific meaning to me (see image below, city of Trier, Willy Brandt, Chalk coast on Baltic sea). My small collection of coins from Greece allow me to refresh my Greek alphabet, words and historical landmarks of democracy. The circulation of Euro-coins with Bulgarian inscriptions in the Cyrillic alphabet will broaden our horizon again. Beyond the national features, we cherish the regional or federal organization in some countries, that feature their regional hotspots within this European cultural heritage. With a highly mobile Bulgarian population, not only within the EU, we shall soon see more Eastern Euro-coins with Cyrillic letters in our pockets and collections. … can’t wait for it … Ukraine in 202x, maybe 203x. 

Digital Environment

We get accustomed to our digital environment through the routine use of applications without even thinking about it. Over years of just using only one browser or office package, we forgot to make conscious choices in companies and our private computers. However, digital sovereignty asks us to take back our control of these computer systems before they take control of us. The AI-boom will make a lot of things easier for us, without knowing much about the technology behind them. Just talking to your smartphone you will be able to achieve many tasks or searches without many of the other steps that were necessary before. The knowledge to command a typewriter or keyboard will be more and more obsolete unless you really need to change something profound on your computer, like the operating system or an expensive office program. Keep exercising yourself with alternative and new software and you’ll stay the master of your digital environment.

Shift to Linux

We have become rather lazy and sometimes even ignorant when it comes to what kind of operating system we use on our computers. The phasing out of security support for Windows 10 based computers creates worldwide a huge pile of computers that cannot update to 11 due to limited hardware 4Gb of active memory only. However, for many simple tasks these computers work perfectly fine. Browsing through the internet or just drafting texts or spreadsheets doesn’t ask for larger sizes of memory. Most AI applications run on the web and not locally on your computer. No need to throw away these devices and spend, spend, spend on the latest technology. It takes a bit of time and effort to read through the guides for such a shift. Maybe you need to come back several times between documentation and a bit of trial and error, but the learning of digital skills is always a rewarding experience as well. My fanless computer will serve me for many more years as a quiet companion in drafting blog entries and research. Additionally, it is a step towards digital sovereignty so many people talk about these days. (Image: Computer Screen with Linux cinnamon 2.2 and Libre Office in background).

Multilingual aging

Some myths, for example about the effects of multilingual competencies on brain health, continue to hunt people. The proponents of a monolingual world are widespread and have in some countries fatal historical heritage. The study by researchers  (Amoruso et al. 2025) use data from 86.000 persons in Europe  (SHARE Database, waves 1-9) from several countries. They show the better aging of brains for bilingual persons and even more so for persons practicing multilingual 2+ languages. The “domain-independent protective effect of multilingualism” for healthy brain aging is very robust and works after statistical accounting for other potentially intervening factors like socioeconomic or institutional factors. Some known stressors like migration, however, which operate often as psychosocial stressor, can have similar negative effects just as alcohol consumption and sleep disruption. Multilingualism and the correlate of multiculturalism keep a brain “on its toes” and contribute significantly to our healthy brains.  

Philosophy of Voyage

In an interview Claude Lévi-Strauss described himself as a philosopher of voyage. The excursions which lasted sometimes several months to live with indigenous people and study their languages, habits and culture became a scientific field of its own called social anthropology. He travelled with his wife and wrote down hundreds of notes and collected items. Only years later the concept of stuctural theory became evident to him. A voyage might go on after the end of traveling. It might start well before departure as well, not the least due to all the preparations. Colette, the French writer and polyartist, coined the phrase “ce qu’on sait faire, au fond, c’est de la route, ce  n‘est pas du voyage ” in the novel « La chatte ». In the pre- and immediate post 2WW years “taking to the roads” often had a gendered view of this with women being rare to hold a driver’s license. To “find meaning through voyages” or “the voyage is the meaning” fill whole libraries. For better or worse, travel books are still best selling books in a shrinking overall book market (less print books sold, but still higher value of sales).   

Polypharmacy issues

As we age, we become more likely to confront polypharmacy issues. Polypharmacy is defined as taking 5 or more medications per day. The study reported in The Lancet healthy longevity by Payne et al. 2025 had participants with a median of 4 health conditions and a median of 8 prescriptions. Even a comprehensive set up which involved several experts from medical doctors and pharmacists did not manage to achieve a significant improvement in polypharmacy outcomes in this experimental study with otherwise carefully matched intervention and control group. However, the mental health (measured in patients as “health-care-related quality of life”) slightly increased and the “treatment burden” experienced by patients was slightly reduced.
In combination with a previous study the probability of errors in nurses, who are the prime persons responsible for the administration of medications in institutionalized settings, the reduction of potentials for errors like they are to be found in polypharmacy should continue to be a prime target of this research in future. Together with the knowledge about the prevalence of functional illiteracy at older ages, polypharmacy remains a critical issue on the public health agenda beyond the experimental settings in this study.

Fighting the Beast

The earliest post 2nd WW cartoon stems from Calvo in France, published in its first edition in 1945. After the first part entitled “When the beast became unchained”, the second part could report on the happy ending “When the beast was overturned”. Amongst the admirable comprehensiveness to talk about the preparation of war, the battles and atrocities committed by the wolves, the allied forces of animals gained the upper hand. The role of women in the fight against the beast takes almost a whole page in the historically precise narrative of the 2 WW. With a fine sense of necessary historical detail, the reporting of British women (the female dogs in the cartoon) as essential part in the war effort to win the war against the beast(s). Women exercised professions were not previously allowed to enter. Gender awareness as early as the mid 1940s was rather advanced at the time.
Great topics to talk about with your children or grand-children.

Embedded Artists

The Brussels districts have their specific identities. 

The Forêt district is reconfiguring itself rapidly. In addition to the Modern Art Gallery Wiels, It hosts a multitude of diverse artists. Many of them opened their doors to the public as part of the 4 days of Parcours 1190. It turned out to be a truly Inclusive experience in the broadest sense possible. The immersive experience of seeing the work and the artists, some of them in their private homes, created a sense of an embedded connection to their work and personalities. The artists are embedded in the district around them nd the people of the district might feel a bit more connected to the artists surrounding them. The artist has integrated the pink poster of parcour1190 into one of his works under the overarching theme of inclusion. Social inclusion can take many forms, The Brussels district Forêt has added new dimensions to it. (Image entry to Hassan Bouzougarh‘s exhibition on 2025-10-5, Brussels Forêt).
