I remember the first time I saw this Calvin and Hobbes strip and nearly busted my spleen laughing. After running for 25+ years and many winters all around the US when traveling .
I also spent 4 chilly years at Notre Dame and northern Indiana gets down into the signal digits and the wind quickly freezes the boogers- eyes wide open and Brain freeze is faster than a slurpee (don’t even think about peeing behind a tree…..)
Keep your sinuses clear or the freeze can silence your brain..YIKES!
If really susceptible- make a face shield with a poly race shirt from last summer.
