When it gets so cold, and the temperature dips well below zero for several days in a row, I understand the animal instinct to hibernate. While I can't shut down my body temperature for an extended winter snooze, I can stay within my warm and cozy house for an extended time with my slippers on, surrounded by magazines, books and warm (or warming) drinks...could be tea, could be aquavit. I love winter and have all the outdoor apparel I need to stay warm, even in below zero weather. I love to snowshoe and I don't even mind shoveling snow. Even so, many days of frigid temperatures make me channel my inner bear :)
