Are you ready for Zombie Attack?

Okay, I know this will sound kinda weird but it's somewhat related to the season - Halloween (although I only got to spend it with my patients in the hospital). My thought is about zombie. I got to watch The Walking Dead and saw an anime called High School of the Dead. I know both are fiction TV shows, but isn't it that technology, as we know right now, came from fiction also? Those touch screen TV or monitors, the GPS, the things our celphones could do, cloning, etc - these and many more used to be fictions only, but now we have them in our era.
