I'm gonna recommend a nice little book called "Machine of Death" about, you guessed it, a machine that tells you how you're going to die!
It's actually pretty awesome, by Ryan North (of Dinosaur comic fame) and a whole bunch of other awesome people!
Now that my shameless selling out is done, as long as my death is either:
1) super exciting and exhilarating
or
2) is once I'm good and ready and am not going to cause mass trauma to the people close to me (if that requires extended suffering for myself, so be it.)
I'll be happy.
Really, I don't want to just disappear. I want to either be a story, or have said story finished with no loose ends.
