Silver - you are silly! LOL
What do we do inside when it's cold outside? Well. . . . . for me, I pretend to clean/unpack my house! Others find other interesting things to do (which is why you have LOTs of babies born in the fall up here in the northwoods!).
Actually, life usually goes on as normal - because extreme cold (-20s and lower with windchills) IS normal up here in January and February. We just make sure to start our cars at least 15 minutes to get it warmed up or have a block heater on the car to help out. I had classes canceled once while an undergrad because it was too cold - mind you it was -50 with -70 windchills (froze an ear as well as mild frost bite).

P.S Oh yeah, and with the snow, you just get some really developed back muscles from shoveling the ick left by the snow plows. Oh, and learn to shovel, walk, etc when you can't feel your legs! LOL
