If I were doomed to cack it in 2012 like that, I'd like to shove someone to safety and out of the path of the oncoming meteor/flood/falling bus/collapsing building/buckling slab of earth/rampaging amazon horde/whatever.
I wouldn't die. I'm just too boss for 2012 to kill me. I'm just gonna camp out with all the people who are supposed to be dead that aren't. Like Hitler, Tubac, Micheal Jackson, Elvis, ect.
I would want to die from an old age in the year of 2095. Hehe you didn't say you would die in 2012 you just said that there would be an apocalypse in 2012. But other than that I would want to be so drunk that I pass out right before a painful death.
Making a heroic sacrifice that destroys an entire alien invasion in the year 2000000000000000000000000000000000000000000000 to the fifth. Much better than "Old age".
If i die i want it to be for a purpose. Ya know? like not just tripping and dying but instead saving someone. Greater love has no one than this, that someone lay down his life for his friends. (John 15:13) Besides i wanna experience death, you only get one chance and i'm not afraid of what comes next.
