Till Death Do Us Part

Lately I have been thinking a whole lot about my own mortality, not just that but loosing those around me that I care about. What actually happens when we die? Where do we go? Heaven? Reincarnation? *gulp* Hell? What will happen to those that we leave behind? What kind of legacy will we leave? Most crucially (actually least crucially but I thought I'd end with a joke) will we come back as Zombies and feast on the brains of our ancestors? Only time will tell...
