I have seen -60 with the wind chill, and it was unpleasantly cold. I worked in commercial blast freezers for a couple of years, and it was not as bad as a bad winter day in Detroit.
Inhaling through the mouth is bad, inhaling through your nose means you can feel the moisture in your nose and airway freeze and crackle almost instantly (probably TMI for some.) Breath tends to condense in facial hair and freeze, and if the cold makes your nose run, you have snotsickles. Stepping back indoors, if you wear glasses, means that moisture will immediately condense on them and freeze. Lee
