In One Piece world, people can leave till 140 years (Oda's words). So it's not sure she's dead, it's only 71% sure (100/140). It's very different from 95-100%, in which case I would agree. --Meganoide 04:08, December 19, 2011 (UTC)
Oda also said in the same SBS that only people like Kureha, who keep themselves in peak health can live that long. Considering Kureha is a doctor in a populated area and Yuki isn't, Yuki probably didn't live as long. Or, as you put it, it should bump it up to the range of probability you want.DancePowderer Talk 07:05, December 19, 2011 (UTC)
