How Do You Want the World to End?

Hello lovies!

I'm back after a much appreciated and needed week away in which I saw my brother get married, the sun burned me up, the mountains were beautiful, and I geeked out with thousands of other people over TV, films, books, comics, etc.

Since I spent some gleeful time thinking about the end of the world at Comic-Con and since The Walking Dead Season 2 trailer was released (yeeee!) and Falling Skies is getting more interesting, I thought I'd pose that all important question to you...

How would you prefer the world to end?

Aliens?
Zombies?
Robots?
Climate/Environmental Crisis?
War?

I think there are advantages and disadvantages to both I suppose, but the last one, war between humans is definitely my LAST choice. What's your FIRST choice?
