Thank you so much for thinking this up and presenting it so well: it has been confusing me for ages, and this is especially pertinent, as I'm part of a Bleach RPG forum, and I was always unsure how to work with my character's aging, because I always thought things like, 'Well, Byakuya and Rukia aged, but they were born in the Soul Society, my character died and went there, so what happens to her??' But, now, I can use this standard to put my mind at ease.
