I cannot really rely on my perception as far as so-called infectious diseases are concerned. I would never have observed and interpreted anything that showed up in me as a cold or flu before 2020 so meticulously with Argus eyes. One was simply sick for some days, then healthy again. That was it. I never paid attention to whether I "might have caught it from someone" and I didn't care because it was normal to have a cold or cough or fever once a year or every two years.
It sounds to me like you are counting it a success for you not to have gotten sick in more than two years. I probably see illness a little differently. It's an expression that something needs to be cured, treated or put to rest.
For me, coughs and colds are part of a process where my body gets rid of waste, just as the excretion of liquids and solids is part of the necessary disposal (going to the toilet). Just as sweat and any fluids that come out of the body are merely an expression of the fact that the human being is getting rid of some substances that it can no longer utilise. So, for example, a cold and a cough are not per se something "to be avoided" for me.
For me, for example, the question arises of what to do with the nasal mucus or deposits in the bronchi if these processes are artificially interrupted or suppressed (e.g. with medication). How and where should these substances then go if they cannot be excreted through the usual transport routes? According to my logic, my body must then look for other ways, and possibly much more laborious ones, to get rid of what it wants to get rid of. Other organs are put under more strain and have to do more, for example.
Probably you know that fever is a process that helps the body to deal with the microscopic waste disposal mechanisms and my understanding is that the acute event of fever is a quick fix to speed up this process.
Of course, what we then notice of it is pain, great discomfort. But why should this be avoided?
From my point of view, the policy of the last few years has caused an immense avoidance attitude, which I basically consider to be very difficult. The consequences of avoidance (social contact and everything related to it) are the greatest horror for me personally and I cope with it very badly.
Anyway, thank you for your relaxed answer and I am pleased that you also see that it is possible to get along with people who think differently or that it is better not to hate each other. Nevertheless, the conflict still exists and I wish that people would not silence relationships to death.
