No idea.

I always say I like the weather when it's like this, and I do. The cool fresh air, the shiny paleness of the world, the break from stiffling heat. I love it. But at the same time, it is a total good mood killer. It makes you feel dull, and numb. Which isn't always bad. But after a long period of time it can result in an unfortunate depression.

Something Hemholtz said, in Brave New World, I can't find the exact quote, but basically he said that he wanted to go somewhere cold, somewhere miserable, if he went somewhere warm and bright, he would never be able to write about the way he truely felt.
