But note that GP has a point about exercise. Though, as the article noted, it's just hard to do when you're chronically tired. And even snow helps, since it increases the amount of reflected light.
Some personal experience, ymmv:
A year ago I started working on the 7th floor in a more southern country than my native Scandinavia, with the roofs below covered with snow. It was wonderful, like being hit in the eyes with a baseball bat of light...
I'm outsourced to Cluj, Transylvania and love it here. Nice people, good food, cool nature, etc. The company is hiring Python devs. :-)
That said, I'm personally interviewing in this city, since Python bores me (and there are some growth problems in the company right now). I hope to avoid London.
