Gone Home

There are at least 2 perspectives on going home. For the person away from home, it could be understood in the sense of returning home. For the community still living at a place associated or idealised as home, it is often interpreted as a home coming. In view of the powerful global social trend of urbanization, many people associate with “going home” as if migrated persons from rural areas would return home to the countryside, maybe just for a short visit. However, a home is to be interpreted much larger than just being a place, a location or a regional idiosyncratic feature, like the sea, the river, the banks or mountains. You might go home to a familiar sounding dialect or language. For some it is the idea of freedom or liberal values which they have moved to, that became their home. For others it might just be the possibility to practice a rather unique sport, which determines where they would feel at home. Home could just be a “state of mind” rather than a location.

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)

Live longer

It is an old dream of mankind to live longer and longer. The Covid-19 pandemic has taught us many lessons that there are powerfully viruses and their continued mutations which threaten this. Life expectancy declined slightly during the pandemic and we learned that long Covid is yet another threat to our life expectancy. Scientists have found other sources that are crucial for survival. Like sepsis, it is the constant inflammation processes in our bodies. Long working times, stressful commute to work and interrupted or shortened vacations all contribute to keep inflammation at higher levels than is healthy from a longevity perspective. The research note published in Nature on the inflammation enhancing protein IL-11 highlights the chain reaction process of inflammation causing cancer and autoimmune disorders and diseases. Hence, it is essential to watch the biomarkers of inflammation and probably adjust our lifestyles accordingly. The sources of inflammation are manifold, but the potential rewards to address the issue are huge as well. Among the easy to address sources is nutrition, exercise and working life. Changing just a little bit here and there can make already a change. Monitoring how you feel about such changes puts you on a learning curve for your own inflammation levels. Vacation times are also perfect for adaptive behavioral changes. We just need to keep trying.

Benchmarks

The physiological benchmarkS of VOPs (Very Old Person) has been lifted by an Irish athlete recently. The 92 year old person has been examined with state of the art physiological measurements to better demonstrate the training efforts and health outcomes of the VOP. In fact the cardiovascular fitness is comparable to a much younger person without much exercise. In differentiation to a sedentary lifestyle the VOP has a daily 40 minutes rowing routine plus 2-3 times resistance training, meaning weights. 20 years without injury made him indoor rowing champion repeatedly. Physiological benchmarks have been extended due to the surprising late onset of the training only at 73 years of age. Starting late with physical exercise allows to reap enormous benefits as well. For physiological fitness it is not only “use it or lose it” but “use it and extend it”. Almost irrespective of age the novel findings suggest a cardiovascular plasticity that was believed to be impossible. The descriptive account in “The Journal of Applied Physiology” allows no causal inference. Many cardiologists would probably even advise against such high intensity training without careful medical examination before, during and after some months. From a statistical or epidemiological point of view this statistical outlier will likely lead to adjustments of algorithmic potentials of human performance in older age. Handle with care, I would suggest. Working against resistance regularly remains an interesting perspective for an aging person and aging societies.

Aging Challenge

Several countries face an aging challenge now and in the near future. The OECD provides some basic data, figures and projections. All data to calculate the aging challenge are more subject to change than they used to. The Covid-19 rise in mortality rates has implications as the number of premature deaths of the elderly (65+) has risen even in the economically advanced countries. The so-called old-age dependency ratio is a widely used indicator to assess the charge or pressure on the working-age population (20 to 64) to finance those in retirement (65+). demographic ratio is defined as the number of individuals aged 65 and over per 100 people of working age defined as those at ages.
Major factors that have an impact on the ratio are mortality and fertility rates as well as migration, but also participation rates in employment for those younger than 20 or older than 65 years of age. Seminal shifts in participation of women in the labour force contribute also to reduce the old-age dependency ratio. An influx of about 1 million of refugees who have immediately a work permit like Ukrainians in Germany have a substantial impact as well. Life expectancy is expected to rise again after the years of reduction due to Covid-19. In 2024 and 2027 these ratios do not move too much. Extending the time horizon to 2050, when people born in 1985 would start to retire shows more reason for concern. Whereas in 2024 France, Germany and Italy are still fairly close to each other (2.4 percentage points), the gap starts to widen as of 2027 (5.5 percentage points). In 2050 Italy is projected to have an old-age dependency ratio of 74.4%, about 20 percentage points higher than France.
Okay, in the long-run we are all dead, says an economist joke, but changes to increase fertility or allowing more migrants in are not in sight for Italy. Therefore, the urge to react is increasing there. Younger generations might not be able or willing to foot the bill of high pension expenditure in Italy. Compared to Italy or even Japan the pressure on France is much less pressing, contrary to the national government’s opinion and policy initiatives to increase retirement age without parliamentary majority.

Virtual Sociology

Abstracting from the real world, the world we live in today or we lived in some time ago, is either speculation or maybe contribute to theory building. Virtual sociology has this potential. Exploring virtual worlds as in Virtual Reality (VR) or Augmented Reality (AR) allows us to take on new roles or experience a wider range of social interactions. This could be the strength of a new field of Virtual Sociology.
In the project in the Jewish Museum in Berlin the composition of a composer murdered by the Nazis in Germany was revived and played in the virtual setting of today’s concert halls. The novel by Kazuo Ishiguro “Klara and the Sun” explores the interaction of a child with her robot friend, when the AI becomes and/or replaces a friend. Virtual creations allow to explore and test more degrees of freedom of social interaction. Experimentation of new social spaces and different forms of interaction need to be explored. It allows a new form of sociology, maybe similar to the 1960s and 70s social revolutions we studied for years to come. Virtual sociology is not a sociology while being on drugs, however interesting this might be for some.
Virtual sociology takes sociology into the virtual world and investigates the new social relationships with avatars or care robots. In programming different social roles (managers, employees) we create new forms of interaction and have an observer within the social world. We may eventually test the Weberian claim of a value-free scientific method of the social sciences. This will inform our need to “supervise” or to guide algorithms that are claimed to do “value-free” execution of rules.
In fact, they don’t. They just reproduce the value system that is installed into them by a “careless” programme (song youtube). The social in virtual worlds is opportunity just as much as risk, but we have to analyse it systematically. As our technological and social environment changes, we have to adapt topics and methods to make meaningful scientific analyses as well.

Medical Personal

Like in many other professions, medical doctors and nurses are in short supply. Labour markets in Europe have changed from high oversupply (unemployment) to shortages of mainly skilled persons. 20 years ago, such skill needs were already visible in projections. In 2023 the discussion of skill needs is spreading to more and more professions. The medical professions are no exception to this rule. Even the best paying jobs will not be filled in sufficient numbers. The German institute for the medical profession (www.zi.de) forecasts, in my opinion, a lower bound estimate of medical doctors for the year 2030. Their projection is based on an underestimation of the growth of the population (war in Ukraine), which they see as about constant until 2030. From the recent figures on the population of Germany there were 1.5 million persons moving to Germany and a loss of more deaths than births of 327.000. Migrants are on average much younger than the German population and, therefore, overall aging of the population is reduced. Tough news for those daring to do projections. Thanks to the immigration of younger persons there will be more persons contributing to health insurance and pay for the higher costs of a rapidly aging population.
Following the projections of the distribution of specialists needed, we shall need more urologists, eye specialists and substantially more psychotherapists. This originates in the aging of the population and the higher demand of younger persons (post Covid-19), as well as refugees, in need of psychotherapeutic assistance.
So-called hog-cycles tell us for the medical profession, with a “production time” of 10 years for a medical doctor, that we are already far behind schedule to address the future skill needs of the aging medical profession and population. This strengthens the need to get serious about prevention of avoidable diseases. Stop reading here, stand up and go for walk. It is the best-practice-solution taking account of the aging of the medical profession and the population as a whole.

Lebenserwartung

Die Lebenserwartung ist in Deutschland trotz überdurchschnittlicher Ausgaben des Gesundheitssystems nur unterdurchschnittlich. Das ist die Schlussfolgerung der Pressemitteilung des Bundesinstituts für Bevölkerungsforschung. Der Mortalitätsforscher Pavel Grigoriev führt das auf die besonders bei Männern (50-64) erhöhten Sterblichkeit aufgrund von Herz-Kreislauf-Erkrankungen zurück. Eine gesunde Lebensweise ist dabei ursächlich für eine längere Lebenserwartung. Walking und Ernährung spielen eine große Rolle bei der gesunden Lebensweise. Also Auto stehen lassen und öfters selber Essen zubereiten. Klingt doch einfach, berufliche und schulische Voraussetzungen dazu fehlen aber weitestgehend in Deutschland. Zu viele Süßgetränke verstärken die ungesunde Lebensweise. Das wissen wir eigentlich lange. Dennoch fällt es schwer, solche Routinen in den Alltag zu integrieren.
An der Tatsache eines überteuerten Krankensystems im Vergleich zu unseren Nachbarländern werden wir ebenfalls arbeiten müssen. Prävention, statt hochtechnisierte Versorgung in häufigen Krankheitsfällen ist die einfache Lösung. Jede Autoversicherung bietet hohe Schadensfreiheitsrabatte für mehrjähriges Unfallfreies Fahren. In der Krankenversicherung könnte das stärkere Berücksichtigung finden.
Der Gesundheitsschutz am Arbeitsplatz könnte ebenfalls durch eine stärkere Beteiligung der unternehmerischen Verantwortung herangezogen werden. Arbeitnehmende im Arbeitsprozess verschleißen und dann die Gesellschaft die höheren Kosten tragen lassen, ist ein unfairer Deal. Große Baustellen warten darauf, angepackt zu werden. Anhand der Daten des Bundesinstituts für Bevölkerungsforschung und des MPI für demografische Forschung lässt sich der Fortschritt der Lebenserwartung seit 30 Jahren aufzeigen. Die 4-6 Jahre längere Lebenserwartung der Frauen gibt zu denken. Daran hat sich über die Jahrzehnte wenig geändert. Die Männer haben zumindest ein klein wenig aufgeholt oder sollten wir sagen, dazugelernt.

Forschen

Forschung betreiben ist meistens das Bohren dicker Bretter. Verständlich, dass das nicht jedermanns oder jederfraus Sache ist. Wer sitzt schon gerne alleine in einer kleinen Zelle und schreibt seine Forschungsergebnisse auf oder liest endlos lange und viel vorherige Forschung? Da ist ein Besuch in Archiven, Laboren oder anderen Datenarchiven schon etwas unterhaltsamer. Forschung ist überwiegend theoriegeleitet. Von Einzelfällen abstrahierende Theorien lassen die Forschenden entweder an diesen Theorien weiterarbeiten oder vielfach irgendeine Form von Daten sammeln mittels derer sie dann die Theorie(n) testen können. Eine Herausforderung an diese Arbeitsweise stellt die rein datengetriebene Induktion dar. Sozusagen der „deus ex machina“ erwächst aus einer hinreichend großen, am besten sich ständig erweiternden, Datenbasis. Wetterdaten, Verkehrsdaten, Krankheitsdaten, Börsendaten und Arbeitsmarktdaten bieten für sowohl für deduktive als auch induktive Verfahren hervorragende Beispiele. Datensammeln in Archiven, beispielsweise Rekonstruktion oder Interpretation eines Lebensverlaufs aus Korrespondenz ist ein klassisches Verfahren von meistens LiteraturwissenschaftlerInnen. Manche Archive belohnen die Forschenden mit Glanz und andere mit Gloria, selten mit beidem. Glänzende Aussichten bietet die biographische Forschung zu Komponisten und MusikerInnen in Paris. In der kleinen, aber sehr feinen Bibliothek der „Opera Garnier“ bin ich zu dem Komponisten Flotow fündig geworden. Es befinden sich dort in der Komponistenakte Zeitungsausschnitte, die 150 Jahre alt sind und ein Büchlein aus frühen DDR-Zeiten, die den Aristokratenkomponist durchaus kritisch durchleuchten. Die Ablenkung auf dem Weg in die Bibliothek und dem Archiv der Oper ist allerdings atemberaubend, also nur für ganz überzeugte Forschende zu empfehlen. Die meisten werden von der Opulenz des Bauwerks so beeindruckt, dass jegliche Forschungsfrage und Theorie „backstage“ verwiesen werden. Selbst backstage kann es ziemlich schön sein.

Repair 2

Ever since the visit to the exhibition “Care, Repair, Heal” at the Martin Gropiusbau in Berlin the image of flying protheses rests with me. Repairing the human body is feasible in many fantastic ways. The inner wounds, however, are less visible and sometimes hurting even more. In recognition of the thousands of victims again in the Russian war on Ukraine’s territory and the atrocities causes by mines to injure humans, we have to assist in caring, repairing and healing. This has not changed since the Great War or the Nazi-induced mass murder and mutilations. Humanity is unable to bann such landmines despite international conventions trying to achieve this.
The strong image produced by the protheses as clouds in the sky (Kadar Attia) remind us of the lasting effects of war. Images we had associated with the mutilated soldiers and civilians of the 2nd world war, many still around us in the 60s or 70s, are coming back to Europe. Writing about the 20th century, Aurélien Bellanger described in words a similar traumatising vision of flying protheses in his story of the lonely poet and philosopher. We cannot repair history, but we can work towards reducing useless additional suffering. It is part of the absurdities of our world that technology has created masterpieces to assist us and reduce suffering, but at the same time technology is applied to create the worst suffering as well. Rather than thinking of this relationship as 2 sides of the same coin, I prefer to hope for dialectic evolution towards a better synthesis solution using enforceable international law. Yes, I still have a dream! …
