...but are those ages still used? I can't imagine that anyone would actually expect us to believe that Sesshomaru is literally 19. As Jaken says, he's been serving Sesshomaru for several decades (in one case, he says centuries). I'm not sure what canon status these books would have, but if either of those incidents were in the manga, they would automatically trump any other sources, since the manga is the highest source of canon.
