Are you the kind of person who prefers the cold weather? Do you love the fresh chill that comes with winter and sends everyone indoors to sit around the fireplace? Wearing a sweater may be nice, but if you really want to test yourself, you should visit Oymyakon, Siberia: the coldest permanently inhabited place on Earth, with temperatures regularly reaching -62°C (-80°F). You'll need more than a sweater to stay warm there.
