SAD..Seasonal affective disorder.. how do you northern guys deal with it?

I have absolutely no understanding of why people would choose to live in cold regions. I love being outside but being in the cold is a crappy way to live.

I would love to live in a warmer climate, but it's not economically possible, at least where I am now the cold weather only lasts for short periods, where I used to live it could easily last for a month or more.
