When I die, I want to make sure I will have left something behind for the living to appreciate. Hopefully, I will have left the world some halfway decent books and stories, or whatever other creative endeavour I manage to make public. I'd also like to leave behind some decently well-adjusted kids, if that comes along.
Barring that, I can always hope I die well.
In a similar fashion, my zombie-plan involves, if there's no hope for rescue, to quietly stuff myself into the fridge to die. The idea is, one day a survivor might be searching the kitchen and popping open the fridge, whereupon my skeleton falls out, possibly with a funny little note. If I'm going to die anyway, I can at least die to someone's amusement.
A morbid sense of humour, perhaps, but really... A good laugh could very well save someone one day.
