People: if you are walking more than a block in temperatures below 20 degrees farenheit, you need to wear a hat. You know what's less attractive than hat hair? Frostbite. Gray or black dead flesh that eventually falls off. It's a lot like leprosy in that effect.
Put your damn hat on. You're not that hot-looking with perfect hair, anyways. A little smooshed hair isn't going to matter much either way. Nobody's looking at you in the first place. Except to say, "Why doesn't that idiot put on a hat? It's freezing out here!"
