I use micrometers µm when I buy a water filter (mechanical), µm 1 micrometer traps debris more than µm 5 micrometers and bacteria, as well as some large viruses.

The military and doctors in the United States officially use the 24 time format, there is something to think about (when we talk about accuracy and adequacy)

Now, yes, because of politics, there are problems of entry/exit to Poland and, in turn, the disruption of economic relations. Millions of residents of these countries suffer because of Western politicians.

No, there are problems in Poland in relation to Russia, older people are happy to speak Russian (and they will tell you the way… They will help with something else, no problem). And this hysteria of yours (as someone said here - they lived under the boot) is truly propaganda of the West. Where did you get it from? In general, the Russians and Poles are Slavic brothers, here they (we) are historically closer than the Germans, the Dutch or the same French (well, you can expect meanness from them to pour enmity). My daughter studied at the Polish Academy (being Russian and Ок). I live 15 km from Poland.

For real!? Remember: youth is not an excuse.

No!
