And why is this a "you and Sei only" discussion? Eh? Soul-aging is a pretty general Bleach concept, you know. *excuse to troll, also fell for bait, also a war against the exclusion*

So obviously Shinigami are going to age differently than normal souls, due to their level of spiritual power. We may or may have not seen this with Renji's and Rukia's friends when they were in the Rukongai. Remember, everyone else in that Hanging-Dog kid gang died except R&R (hah). Even if they died from sickness, starvation, what have you, I'd say you can put a large stack of money on the fact that normal souls age differently than "shinigami" (or potential Shinigami souls).

My own theory on the matter is that, sort of similar to what Sei suggested, that souls age in stages. Now, for a normal, non-reiatsu possessing souls, I'd say you either age gradually but very slowly. For souls who DO have some level of reiryoku, they age in more like ten year gaps. Meaning, they will grow from age 1 to 10 at about the same rate as a living human would (maybe a bit longer) and then they hit stasis. Or a plateau or what have you. They'll remain stuck in that state until something triggers a progression, or the next stage of aging. In which case they age at a pretty normal rate from 10 to 20, and then hit stasis. The cycle repeats itself until the soul reaches the end of their life and dies. Obviously, that period of stasis could fluctuate wildly depending on the individual. Yamamoto vs. Hitsugaya, for example. But that is just my idea. Could go to explain why their are so few teen-aged (?) shinigami out there. It's like, they go from being kids to BAM! "We're all adults now!" (This is speaking of their so-called "physical" age, of course, not their maturity level. Although, I guess following the system I have here the two should go hand in hand. Meh, whatever. X_x)

My suggestion? Why not come up with your own system as to how it works? Not that it has to be a system at all, just that there should be a reason for why the individual aged as they did. It's very much a case-by-case sort of thing, imo.
