Time to prevent

If we take a medical life course perspective, we shall become aware that for each event there shall be a time to prevent it. From a scientific and socio-economic point of view, this is the crucial time to prevent failure of an organ, duration of an illness, death or an otherwise disruptive event. Taking our lung or liver as examples we intuitively know that there is a long time spell during which we have a chance to work on prevention. The monitoring of the early onset of disease is (Ge et al. 2026), potentially, a very cost-saving way as well in addition to avoid humans suffering later on in multiple ways. From a theoretical point of view it will be interesting to “think intervention as prevention” already, rather than the predominant way of intervention “post-hoc”, which means after the onset of disease. This implies a rather complete overhaul of medical research just as much as social research to guide policy makers interested in the “survival” of our social security systems as we know them currently in Europe.

Time wasted

It is a rather narrow, mainly economically driven, view on time that time can be wasted. Maybe, it is just interpreted as the opposite of „carpe diemcarpe diem“ (make use of the day). In the immediate instance time might appear as not used in a productive manner, but with a longer time perspective in mind, wasted time might happen to have contributed substantially to a valuable outcome. The measurement of time can be done in a neutral fashion like using a digital or analog clockdigital or analog clock. Time wasted, however, is a judgement and attaches a value on a duration. In retrospect, or from a life review standpoint, wasted time may be subject to revision. How much of reading is wasted time? Some reading becomes relevant only at later times during the life course. Just keep wasting time this way. Sing songs like from Honahlei „Where has all the time gone“, there will be long term benefits.

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.

Illness duration

The focus in medical analyses is primarily put on the diagnosis of illness. This is the best strategy, if the onset of an illness has a precise beginning and ending. In all processes, where either the beginning and/or the ending is less well-defined as precise point in time, the progression, as phase in or phase out of illness, is also of substantive interest. A duration analysis can inform about the potential presence of a co-morbidity in case, for example, an infection continues beyond the normally expected duration.
Financial pressures in the medical systems makes it necessary to release patients in a timely fashion. Therefore, has become more important to monitor patients even after release from hospital. Digital devices can support such a monitoring.
The study by Josi Levi and co-authors (2026) shows that smartphones or just the monitoring of the number of steps of patient offers a rather reliable indicator on the health status towards the end. The information that a patient has recovered to the normal level of activities as before the onset of the illness works quite well as indicator of recovery. A more precise measure of the duration of an illness is important for patients, care persons, the health system overall. The duration is one of the cost-intensive factors of any illness and it is surprising how little we know about the issue of time and duration in many health processes.

Time and power

Who commands our time? Who commands your time? Both macro- and micro-level analyses of power relationships related to time need to be investigated. Time policies are most obvious when it comes to regulations of working time, permissions of business hours or so-called bank holidays. On the micro or individual level, it is often the question of who spends more time on work, care and repair. Hourly wage rates have been claimed by economists to guide or decide societal time spent on one or the other activity. An extension of this rationale with an overriding objective of happiness might considerably change the impact of power relationships on time. Longer time perspectives on health shall also shift the view of how power impacts the time spent on various activities. Time sovereignty is a precious value in its own right.
The power play between employers and employees keeps shifting the balance, albeit the overall trend over the last 100 years has been towards a reduction of working time and increased time sovereignty of employees as a form of democratization of working life. This constitutes one form to share the benefits of productivity gains over decades as well. (Image clock on Berlin City Council building on labor day 2025).

Time reference

Times serves as a point of reference. We often refer to precise points in time, like dates 1st of May Labour Day, or a specific hour as a reference point. If we talk about 5 minutes before 12 o’clock, we convey a kind of urgency – before it is, presumably – too late. In the arts, particularly poetry, prose or drama, and even beyond the romantic period, the reference to seasons as “emotionally loaded” terms is widely used. Subsequently, there are many compositions in music, which make use of such references as programmatic titles. Through the reference to a specific duration, the scene appears to be set and the reader or listener prepared for a less surprising experience. You might even go full circle like in Vivaldi’s composition of “The 4 seasons”.
The writer, poet and Shakespeare translator Thomas Brasch (Link to publications) has written the poem “Der schöne 27. September” (1980) with an exact reference to a point in time, but reporting in 10 lines, what he didn’t do on that date (own translation).
“I didn’t read a newspaper.
…
I didn’t write a single line of text.
I didn’t set something in motion.”

Time Concatenated

As a measure of the psychological and social pressure time may convey on people, it is useful to look into how time is concatenated. In a calendar we often make appointments in a form where time is concatenated in ever smaller time slots and condensed time sequences. The organisation of appointments into slots of 15 minutes, with or without a break in between, might be a dense schedule, but we have come to think in time as linked to dates, space and precise timing. We shall experience time as rushed or forcing us into concatenated sequences in our professional life more than in our private life. In IT we even integrate these separate columns into just a single column for computing efficiency. Our calendars allow to structure time in ever smaller sequences. We tend to organise our lives more and more according to these shorter concatenated time.

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.

Time as surprise

Sometimes, time comes as surprise. Time seems to run faster as we perceive it, or time might pass more slowly in actual terms than we perceive or think it does. What makes the difference? There is the objective measure of time with various types of clocks and watches versus the subjective or perceived lapse of time. The discrepancy between the two constitutes an interesting case for further study. Marketing strategies will try to make us believe that a specific kind of product will shorten or lengthen the difference between objective and subjective time. The entertainment industry works very hard on our perception of time relative to one or the other form of entertainment. The best result seems to be that objective time has been much longer than perceived time so that we “lost” our reference to time while being entertained. The so-called social media interaction is rather successful in this form of entertainment, infotainment or edutainment. The moments in life when time comes as a surprise might be great ones in our lives. Particular deviations between objective and subjective time make strong impressions on our memories, too.

Time and Emotions

In psychology, time and emotions are a matter of milli- or even nanoseconds. Showing emotions, intrinsic ones or controlled ones is passing rapidly through our brain and, for example, facial muscles. Hence, time plays a role in how we react emotionally to an image or any event. The author Rüdiger Safranski starts his history of the concept of time with the emotional experience that time appears lengthy or tedious. In his view the emotional understanding of the concept of time is key to a better grasp of the philosophical roots of the concept of time. Starting with Greek philosophers, the Stoic tradition, Augustinus, the history of ideas is full of reflections on time, what it does to us, and how we best deal with the effects time has on us. In famous literature from Marcel Proust or Samuel Becket, we were reminded of the creative power of lengthy periods of time and the importance or futility to ask fundamental questions about time and our destiny. Beyond the rational thinking about time, the emotional experience of time makes up much of the spice of life.
