Seriously though: I grew up abroad. I stay up late. I go hiking and canoeing as often as I can. For someone who never practices, I'm really quite good at table sports. I think a lot about exsistenial threats to humanity and civizational collapse and if the moral arc of the universe really does bend towards justice. All kinds of fun stuff like that, really. It's not that I like dwelling on the depressing, I just like the big picture view, and the big picture is kind of ugly. But it's also fascinating. If you want to understand how this world view translates from the macro level to the personal, you couldn't do much better than watching this 30 second clip: http://www.youtube.com/watch?v=xEUh4FZIf8E .
I also read a lot of non-fiction.
Film: Jurassic Park, perhaps the most fasinating documentary of all time. And so well paced.
Television: Jeopardy, mini series on HBO and Netflix. Good documentaries.
Podcasts: Pretty much all well made history podcasts (and even some not so well made ones) but in particular Mike Duncan in both the History of Rome and Revolutions. Most of the stuff on Gimlet media. TAL, Radiolab, all the NPR stuff. Various true crime stuff though not the really lurid/justice porn crap. Anything that holds my interest while I work.
Food: I eat it all.
