I'll occasionally do this for some authors, hopefully that's not too creepy. A lot of my favorite authors actually lived pretty interesting lives so far as I can tell. Which I guess shouldn't come as a surprise. Tolkien, Heinlein, Frank Herbert, Stephen King, to name a few. It's interesting delving into their pasts to know where they got some of their ideas and inspiration from. I guess it's just interesting to me as an on/off creator myself.
