What are the life spans of each blood caste in human years? Do they mature more slowly if they live longer? Like would kanaya age faster than feferi?

We don’t have much of a set number, I believe Rustbloods live 20-30 Human Years, and the rest of the Castes’ lifespans are exponentially longer, with Seadwellers ‘basically living forever’, but we don’t have like, a specific scale other than I believe mention that Highbloods can outlive hundreds of lowbloods.

That being said, every Beta Troll is 13 and looks roughly the same age, and every Alpha Troll is 19 and looks roughly the same age, so it’d seem they all kind of age at the same rate, and then when they reach adulthood… Stop aging?
