This is what happens when you go running outside in single digit weather. It was a chilly but good experience. After running on the treadmill for a while, getting outside was a welcome experience. From a purely functional standpoint, facial hair, especially in beard or goatee format, provides a nice guard against the biting winter wind. I've thought of going to a cut down format but each time I've recently been outside have reconsidered the benefits of said hirsuteness.
