There are a lot of points of sale for food products here and they are extremely different, and there is no dependence at all on the quality of the price - you can buy some very expensive garbage, or, on the contrary, cheap - quality products. In this regard, it is absolute chaos.Once upon a time, back in the days of the USSR, the government fixed all prices for everything, and anyone who resold something could easily end up in prison (!) as a speculator, this slowed down trade considerably. Now this has been removed - and anyone who is not too lazy trades, and the supplies are also absolutely strange, sometimes local, sometimes from very distant regions, or even imported.I am fascinated reading your humidity examples.
I am living in the city so I buy from corporation supermarkets, we have 2 big supermarket dominating the food market - I have no way of buying it from the actual producers and they are most likely not selling to the general public.
We open the windows whenever it is sunshine, and we have many large windows, but the excessive water just no way be fixed.
As for air humidity - I once had an electronic barometer showing air humidity, but then it got lost somewhere, and we did not buy a new one. On one wall there are old-style pointer barometers, but if I am not mistaken, they only show atmospheric pressure. I haven't looked at them for a long time, I'll have to see what they show. And I can only estimate the humidity of the air approximately, using electronic incubators, where it is adjusted and then it is visible: if the humidity of the air is higher than the set parameters, then they do not pump water, and if it is lower, they pump and add humidity for the eggs.
Otherwise, the climate here is not humid, but at the same time not dry, like somewhere in the desert. Something in between. Therefore, both heat and cold are not perceived so hard here. Although in winter, with the drop in temperature, the humidity, of course, will drop - the excess "water" in the atmosphere will turn into snow. When the temperature is above the freezing point of water - then, oddly enough, it is worse, because there is high humidity and cold. Therefore, the most dangerous month for colds here is March - when there is no constant frost, but it is damp. And some people, who calmly walked on the street half-naked at -40 C, get a bad cold in March at +5 C from the cold. Therefore, in March it is customary to dress warmer than in winter. Well, then in May the sun shines strongly, and the spring sun is quite harsh - it can even damage the bark of trees. In summer, we can't get as badly sunburned as in spring.
As for the barometers, I didn't really understand how to use them at all - they show rain during rain, storm during storm, hurricane during hurricane, but they don't show anything in advance. I still don't understand what the point is in them, if what they show is already visible from the window )) Maybe I'm doing something wrong.
