The Turkish hot springs where residents bathe with water buffalo

When temperatures plummet in eastern Turkey, people round up their buffalo, get outside and strip off.

Key quote: "As anyone who has lived in subzero climates for more than a couple of winters knows, staying sane means getting out into the world, whatever the weather."

But as OZY writer Stephen Starr notes, buffalo numbers have dropped precipitously, thanks to urbanization and kids moving off the farm.
