When I was growing up in Northern BC, Canada, my father told me that Eskimos were different from Caucasians because they didn't have sweat ducts - they didn't need to sweat because where they lived it was always cold. I believed this well into my teens, when I repeated it to a friend who laughed at me. That's when I realized my parents sometimes lied.
