Google Now & an unexpected downturn of being a fanfic author

Just thought about the Google Now feature in my Nexus tab. According to Google, it uses my location, calendar, and search history (among other things) to predict the information I might need next and display it without me having to ask for it first.
Nice idea. However, I won't activate it. It's way too dangerous in my case! My location history is empty (I disabled it), my calendar is filled with when to water my plants (mostly), and my search history is story related...

I don't want Google Now to display the flight schedule between Tokyo and Okinawa (I'm nowhere near there), the traffic situation in Ueno - Tokyo, and the "101 ways to entertain your cherry tree" while calling the police to my doorstep because said cherry tree is so well fed. ;)
