Medical Life Course

The analyses of the life course have taken individuals as their starting point and linked their life courses to broader societal developments like periods of educational expansion, job growths or periods of high unemployment. Medical life course research has further dis-aggregated the life course of a person into, for example, the life course of human organs.
There is already an established line of research which collects and analyses lung function trajectories. The research starts even before your first “autonomous” breath and typically ends at death, although transplants become feasible. It is helpful to think of those measures lung function trajectories as a life course of lung health, because the air we breathe is subject to many social and environmental impacts. Some we are in control of (active smoking, less so with passive smoking), some others like inner city smog or pesticides inhaled in areas of agricultural production. Work environments play an important role in the life course of the lung as well. Global warming, particularly increases in summer heat, pose additional challenges on the overall aggregate level to lung health trajectories.
Inhale, exhale, … then force your breath out quickly, … keep breathing normally. That’s about the instruction for the “Forced Vital Capacity test”, which is a standard measure of your FVC just repeated over the life course.

Multiple clocks

There is nothing more confusing that multiple clocks that are ticking away without being synchronized, which means, they ought to show the same time. A medical and social science perspective on multiple clocks, however, builds on the fact the different social processes run with different speed, i.e. multiple clocks are ticking in parallel but one may be more advanced than the other. The study of longevity has recently acknowledged that each human organ is aging at its own speed and if the time to failure is close for the liver, the time until problems of your heart might still be far off. Overall longevity is determined by the time to failure of a major organ, despite the fact that multiple clocks of organs are running in parallel.
The can be observed for social processes where, for example, the timing of unemployment or retirement might be dependent on a parallel process of a household dissolution causing a peak in stress. Overall life satisfaction, therefore, depends largely on multiple clocks that might be running in a synchronized or not-synchronized manner. Hence, we all live with multiple clocks ticking inside us and around us. The illusion is, to believe that time is just a single, unique measure.

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.  

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.

Marc Aurel Book 10

Book 10 offers some referrals to previous books and topics: Marc Aurel defends a wholistic vision as in book 10 paragraph 17: “Keep constantly in your mind an impression of the whole of time (χρόνον) and the whole of existence (οὐσίαν)…” (Penguin Classics version, also in Greek original/French translation). In the same vein, he wants all this knowledge and considerations to be “actionable”. This reads in his words: “No more roundabout discussion of what makes a good man. Be one!” (book 10, paragraph 16 in the same two editions). As the late Marc Aurel’s writings progress, he becomes even more “exigent” in the sense of demanding ever higher standards (of himself). “Whole-ism” paired with a request to, nevertheless, be ready for action at any time is not only a high cognitive demand, but also a reminder to leave procrastination behind. The virtue of a stoic leadership style remains an ambitious challenge.

Vacation Waves

One of the most popular choices for a vacation is in connection with waves. There seems to be something mystical or romantic related to waves, which touches many people irrespective of their background and across continents. This goes much beyond what we know about waves from physics or maths and this is already a fascinating scientific story in itself. Sailing adepts will be able to tell marvellous tales about waves, too. Coming back from a vacation near the sea or a lake, you surely may add another story to the already rich inventory of waves in art or literature. The imagery about waves started early as well, ever since sailors started to conquer the world.

Femmes Photographers

Paris puts 2 women photographer into the spotlight. The MEP and the Musée historique de la Ville de Paris feature a gender perspective on photography. Both photographers have a common starting point in black and white photography.  Each moved on to develop their art into an additional direction later during their career. Marie-Laure de Decker shifted from the early camera technology from black and white images to color photography in the later stages of her career. Agnès Varda moved from her initial b/w photographic work on to the production of videos for cinema, mainly focused on life in Paris from the early 1960s onwards. An evolution over the professional life becomes evident for both through these retrospectives of their respective work. Technologies evolved and became more accessible for artists’ creative expression. Both moved on to adopt new techniques and challenges. Great personal learning experiences and models for today’s challenges.

Social promise

In the beginning and middle of the 2020s the social promise to younger generations has been broken. The latest figures from the USA reveal that 2 million students (WSJ 2025-6-25 A3) who have financed their studies and potential social mobility by taking out a substantial loan are very likely to default on their credits. This observation was less a surprise to labor market analysts as the stalling of student hiring in many countries has happened for several years now. The more surprising finding is that the Wall Street Journal 2025-6-25 has been reporting on this. Banks or universities who are highly exposed to this kind of risk will themselves become downgraded for their credit rating. Higher interests for universities means higher fees and higher student loans eventually. The social promise to reach higher status and earnings through higher education as the social promise of the meritocratic society becomes an illusion. Investors in student housing might also find the sector less juicy for them. Students and their parents were taken hostage by an excessive commercialization and commodification od education. Lifelong learning is a still a promising route to revitalize the social promise.
