Everyone, Pardon me if this has already been discussed (newguy here).

How is it possible that a Death God can be sick like Ukitake? I mean are there some spiritual viruses out there or what, and Why can't Unohana heal Ukitake ? Just how is it possible that a guy who is already dead can get sick and die again?

If Shinigami die, do they get reborn on Earth or do they go to true heaven? Even worse Byakuya lost his wife to ilness, what became of her spirit?

What would happen to Ichigo if he died as a human?

ARRRGGGH! My head is exploding, somebody help me please!
