The average temperature (-50 C) is equivalent to the average temperature on Mars, and the coldest temperature recorded was -90 C. However, life carries on in Oymyakon. There are shops, hospitals, schools, and all other signs of civilisation. In fact, it has to be -60 C before schools are shut.
The cold causes all sort of strange problems – clothes can’t be dried outside, because they freeze. Cars have to be left idling, so many prefer reindeer sled for a means of transport. Batteries immediately die, so electronics in general are pretty useless. On the plus side, all it takes to refrigerate your food is a basement. Oymyakon residents eat a lot of thinly sliced reindeer meat, and cubes of frozen reindeer blood for snacks.
