Well, worst thing to happen is to die and have no one around to see you die. Basically, if that happens, no one will know your dead unless they are looking for you or they did see you die or someone walks by you by chance.
Anyway, I was dead and thinking in my ghostly form, "why the hell can't I just wander around detached from my physical body?" Makes sense since there is the wandering ghost themes out there. Besides making this a way to get help for yourself, it is also an RPing opportunity as well.
That's my 2 cents for today on the after life.
