It doesn't fit into the rhyme, but -10°C is the point where just wearing a coat isn't enough. You need to either start limiting the time you spend outside or put some serious thought into the protective clothing you wear beyond just throwing a coat on as you go out the door.

I had a water bottle in my car when it was around -11 °C, and when I tried to drink it, the supercooled water instantly froze solid, which was startling, but hardly surprising.
