I'll try to break it down by numbers...
8% history
6% religion
22% philosophy
10% getting fucked up
14% "What the fuck am I doing?"
8% food and/or water
12% anime/hentai
8% sex related
11% random trains of thought
... and trace amounts of 15 other elements...
I'm pretty much certain that isn't accurate. My mind is far too complex to analyze.
