Ah-ha. Well then, thank you to Void and Sei. I could not even begin to describe how many times this threw me off. Even in one of the flashbacks, Yama describe his Bankai as "a monster that appeared in the Soul Society many years ago" so it is possible he could be 4000+ years old...I think there should be a little side book that Kubo does that should explain how it works.
