Wow -70f? I would die in a minute with such insane cold! I might be able to survive wearing a spacesuit with a heater attached to the back. This is how astronauts keep warm and alive on the moon! I would never live anywhere that gets colder than -10f because I do not want to risk my life. What if the heater breaks or I am shopping and freeze to death while waiting for the bus? Id like to live north but not in the arctic!
