20 Below

I freaked out a little when I pulled up the temperature on the computer and it read "-20". That's cold. I forget every year that there is a difference between 20 degrees and -20 degrees ... a lot of the time once it gets to 20, I just think, Man it's cold, better wear some mittens. But there is huge difference. I sat in the car this morning, desperately praying for heat, and thought it out: -20 is almost 50 degrees below the freezing point. And fifty degrees above the freezing point is 82 degrees, which is a subtropical temperature, which is what human beings are naturally adapted to function in. So 20 below is almost 100 degrees below the temperature nature prepared us for. And yet, here we are, going to school, going to work, going to the grocery store, instead of huddling in caves around fires and eating leftover mammoth.

See, it's so cold I'm starting to get a little delirious ...
