I grew up in the Northeastern US, snowy winters and all that. But its strange, even when I lived in sunny Southern California and it was 80 degrees and clear in December I'd still feel a little depressed and would sort of hibernate in the winter time. It was frustrating, because I knew damn well that it was beautiful and sunny outside and I shouldn't feel this way but I did.

Something inside of me is just biologically hardwired to know when its winter and that I should be hunkered down inside when it comes around. It wasn't nearly as big a problem in SoCal but it was still there. My guess is that my generations of northern-dwelling ancestors developed a genetic predisposition towards conserving energy in the winter but I'm no expert...
