I'll list a few of the big interests of mine:
-Tide Pods
-Cyanide
-Mysteries, especially ones of the criminal or disappearance variety. Jane/John Does are some of my favorites. Or just generally "this person went missing, where are they?"
-Historical Mysteries like The Man in the Iron Mask. I guess that's kind of the same thing as Mysteries, but who cares!
-Music! Even though I've pretty much given up on Guitar I can still listen to it! It's fantastic!
-Writing. I used to write a lot of reviews and some day I hope to start doing so again.
-Thinking about what things I could accomplish in an alternate reality.
-Arguing.
-Other people's way of thinking.
-Video Games.
-Sometimes anime.
That's all I can think of : /
