Contrary to a lot of received previous recommendations, the shorter duration of antibiotics prescription and use (3-5) days is overall better than the prolonged use of durations between 7-14 days (JAMA Link). A so-called narrative review of medical studies (Lee et al.2023) reports more precise results separate for medical indications (pneumonia, sinusitis etc.), which tend to go in the same direction for the majority of indications. In view of the serious issue of antimicrobial resistance, a consequence of overconsumption and too widespread use of antibiotics (also in animal health and food production), the slogan of shorter is better should receive serious attention.
It is not only a medical, pharmaceutical or public health issue. The topic has become an issue of nutrition as well. The food chain contains largely unknown amounts of antibiotics as well, especially if larger amounts of animal or fish products are part of it.
The knowledge from these sciences has still to filter through to the broader public. This means it has become a social science topic as well. The transmission of knowledge and patient expectations on prescriptions, which is also linked to regulations concerning sick leave, make it more difficult to shorten prescriptions of antibiotics. There is a steep challenge to change behaviour according to the new mantra “shorter is better” with respect to antibiotics, even if we know that it is better for all of us in the medium or long term.

On Resilience
There are at least 2 definitions of resilience: (1) a material definition points at the “ability to return to an original form or position after being compressed, extended or curved, and (2) a immaterial or psychological definition. The latter one describes the ability to recover, be happy or successful anew having overcome a bad or challenging experience. The American psychological literature defines resilience in the shortest form as “positive adaptation despite adversity”. The psychological construct is linked to a positive life span perspective of personal development. Other areas of application range from “resilient investments”, “resilient industries” to single resilient societies or intergovernmental organizations like the European Union or NATO.
The challenges to resilience increase with complexity of societies and social as well as technical systems. As supply chains have become longer in time and travelling longer distances as well, the improvement of resilience has become a steep challenge for globalization. Reorganizing supply chains with “own sourcing” as in countries which are cut-off from international trade will have huge consequences on sending and receiving countries.
Last, but not least, countries like Ukraine demonstrate the fact and virtue of resilience after more than 1000 days of the massive Russian invasion of its country, which threatened its survival. Resilience works best in networks of organizations and countries. Solidarity is a fundamental building block of resilience as well. Donations and funds support activities that foster resilience. 
On Dosage
- Dosage is key. We all know it from everyday expériences. Certainly from drinking alcohol we know the tricks that dosage can have on us. Consumption in small doses is fine and enjoyable, but larger amounts cause all sorts of trouble. In pharmacology the effect of dosage is applied with particular virtue. Small doses even of a poison can have beneficial effects. More of rhe same might well kill you. The same rationale applies to other fields as well. Physiological training effects depend a lot on the right amount of training and the timings or intervals between training sessions. In managerial, economic or social applications the question is not only about what is the right remedy, but also how much of it. The interest rate decisions of central bankers are mostly concerned with dosage rather than « whatever it takes ». A minimum wage increase is equally about dosage and we all have additional examples.
Even in art, take painting or music, dose and pose, that is the question. It is quite surprising that such an overarching issue has received rather little attention, comparatively or only among specialists in each field.
It appears strange, but it is possible to have only a little bit of war, as opposed to comprehensive conflict. The applications of dosage are manifold.
Learning about dosage might prevent binge learning at first and binge viewing later on. In the age of tiktok and social media, dosage has become a key competence. (Image Extract of Gustave Courbet Die Welle 1870, Alte Nationalgalerie Berlin).
On Intersectionality
Society deals with individualization or individualism in various forms. One way is to take each social group as a specific singular case. This is reasonable and justified in many instances. There are cases where this form of dealing with specific social groups comes to limits. Following the rationale of plurality and individualism it has become common practice to address each target group in a specific manner. Intersectionality, however, acknowledges the overlapping of target groups, which necessitates a more specialized approach to intersecting (social) phenomena. Gender might not be the single most important factor to describe a person, just as age is a concept of various intersections. Chronological age versus age defined through biomarkers demonstrate the variety and potential for intersectionality. The Paralympics 2024 in Paris gave another positive example of intersectionality as extraordinary persons achieved previously unimaginable world records in specicialized disciplines. Individualization and classification is only a first step in the scientific endeavour, the analysis of intersectionality is an additional step to consider in a broad range of fields beyond the social sciences.

Bi-directional Sleep
For most of us bi-directional sleep is a question of sleeping on the left or right side, or on our back or front, head left or right. In immunology bi-directionality of sleep has another meaning. The immune system is linked to sleep in a bi-directional manner. Good sleep enhances the immune response of cells (direction 1) and infected blood cells for example send a signal to the brain to extend sleep. The study by Huynh et al. (2024) in Nature has demonstrated this bi-directional mechanism. It allowed mice who slept well after an imposed heart attack to recover in a better way than those whose sleep got interrupted during the experiment. The most natural response to a heart attack or acute coronary syndrome is more sleep. This is induced by an inflammatory reaction in the brain, which « orders » your body to increase deep sleep. 😴 Sleep is more than just rest, it may be part of healing. ❤️🩹 (people looking at Caspar David Friedrich „Infinite Landscapes“, exhibition Alte Nationalgalerie Berlin 2024)
Water Quality
Obviously, water is not just an issue of quantity, but also quality. The availability of sufficient quantities of water in a region depends on rain, its storage, and the use of these water resources. The quality of water is a subsidiary issue, as lack of inflow causes concentrations of nuisance in water to rise. Global warming will most likely intensity the concern for not only the quantity, but also the quality of water.
Public services are in charge to sample and monitor levels of water quality for consumers. Independent of public, private or public private partnerships in this field there is a need to check from time to time the quality of water. Public institutions do a great job in monitoring water quality, but as science progresses there are new sources of pollution that enter the already complex analysis of water quality. New chemicals and remains of medical or pharmaceutical analyses have been retrieved from water and, sometimes, they have reached critical or unhealthy levels.
More detailed monitoring is necessary and new digital tools allow to improve just this type of monitoring to inform policy makers on shifting patterns.
A project of that type “Urban Green Eye”, for example, allows to monitor the artificialization of previous vegetation to show up on satellite images of Germany. Independent groups, citizens or communities might find it useful to use their own sampling and testing to guard against abuses or dysfunctional public monitoring systems. Start-ups like “Hydroguard” offer services to support activists, communities or public services in their own efforts to ensure water quality. 
Public health info
Public services have a premordial role to play in providing reliable and up-to-date information on health issues. It is no longer only in charge of collecting this information, for example on infectious diseases, but public services are in charge of timely disemination of that info as well. This is, of course, were online services and AI come into play. Getting out this info is crucial, but in the age of fake news and the wide disemination of news on social media, public services need to check also what becomes of the news they have published. The Covid-19 pandemic has been a worthwhile experience in this respect. It is important that reliable information is transmitted via trustworthy channels, which have already been established prior to the “next” health crisis. Many innovative tools were presented at the SCCON 2024 and maybe trustworthy video calls with a medical doctor or your pharmacist may constitute a solution to many infectious pandemics. However, trust in the technology is important as well as equipment and identification systems to be sure that your medical doctor you meet online is actually a medical doctor or only a savy pretender. The issue is as old as medical assistance. The RKI in Germany is the reference information for coordinated information on many public health issues like infectious diseases.

Risk Takers
We are all risk takers of one form or the another. Those of us who ride motorbikes or enjoy rock climbing have an above average taste for risk taking. Since the publication of „The risk society“ we are aware that collectively as a society we have taken on additional risks like nuclear energy, atomic weapons or the risk associated with silent climate change with the persistent reliance on fossil fuels to a large extent. Holman W. Jenkins (WSJ) has added an additional perspective on risk takers which originates from government policies to encourage building homes in places subject to high risks of flooding. Several policies come to mind that encourage individuals to take high risks and construct and repair buildings in flood prone areas. Government grants, insurance policies and relocation subsidies are at issue here. Regulations like driving licenses try to build on competences to ensure „more rational risk taking“ in people. Teaching about nutrition might alleviate the obesity pandemic as much as awareness of an active lifestyle can avoid a large number of cardiovascular diseases. Risk taking should be to a large extent an individual’s choice with the consequence to live up to the consequences of the risks taken also more an individual’s responsibility. Collective solutions are a powerful way to encourage additional risk taking. The consequences of those well-defined solutions have to be funded collectively as well. A society-wide discussion and voting process on such issues has to be organized and updated from time to time. (Image Skateboard high and long jumps Brussels 2024-10)
Science Fraud
It is a big issue if publications in science in high reputation journals have managed to pass a rather lengthy and thorough peer review process and still contain evidence based on fraudulent data. The worst case scenario that based on this wrong evidence tests of useless drugs are performed on patients in hope of an honest concern for their health. In fact the financial rewards and even academic rewards have been achieved only through the successful publication of a bias introduced into the data and/or analyses of the data. The fraudulent researcher became subsequently Director of the institute of agingwhoch is part of the American National Institute of Health (NIH) and an academic reference in health sciences far beyond the USA. It is the merit of Charles Piller and his team to persist in challenging the treatment recommendations which were concerning Alzheimer and Parkinson diseases. The checks and balances in the academic research have failed and a serious reconsideration of the procedures should follow, not just business as usual. The reputation of scientific research is at stake beyond the natural sciences and medicine, although the normal way of proceeding is just to qualify such events as singularity and specific to a single discipline. Aging is also not just treated by one single discipline. Hence, there is a need to review the review process and publication practices. The Boeing airplane control failures were also indicating that reviews of technology are subject to high risks. Independent checks and control are hard to ensure in advanced subject matters, but sufficient time and resources have to be devoted to the process. (Image Repair Lab Deutsches Technikmuseum DTM2024).
Happy Runner
The happy runner is a nice example of how hard it maybe to experience happiness through running. The so-called runner’s high is available to everybody, if you manage to run long enough already. Most predictions put the threshold distance at about a 1 hour run. The reward for this effort is a special feeling that exceeds the pain or it makes you forget or supress the pain at least temporarily. Special reinforcements can be achieved through the big city runs in exciting places with thousands of people cheering you on. This has become a big business as well. Training for such an event might raise your feeling of happiness substantially. The chemistry of the endogenous production of stimulants of happiness in our body has been enlightened substantially in recent years (partly as doping control). Most of the brain active drugs our body can produce itself, although this involves a lot of physical and mental effort. The rewards are pretty healthy for most runners contributing to their basic level of happiness. Running outside, has contributed more to happiness for me more than the same exercise on a treadmil. Maybe, the environment is part of the happy runner’s high effect.
