While there have been very little indications of the racial lifespans and cultural markers in game, I figured I would ask about it here and see if Squeenix might give us the answers out of game.

Basically, what I'm looking for is the average and maximum lifespan for each race, and what their age mile markers are. So basically, something like this being answered for each race:
Childhood: Birth - ??
Teen Years: ?? - ???
Adulthood: ??? - ????
Elder Years: ???? - ?????
Hopefully, Squeenix will give us some clarification, since role players do use age and age markers quite a bit.
