No, you're not "pretty old" or even a little old. You had to be pretty young to cry during that movie and/or believe it was real, which makes me think you're not older than 15.Turns out the movie came out 5 years ago, so you're still young, even if you're in you're in your 20s. Sure the end of the world is a scary thing, but not if it's something dumb and implausible like the mayan apocalypse.
