I'm hoping, with the addition of the Lore forums to the official forums, that they'll add details like average height, weight and lifespans for each race.
Until then, I'm presuming (for age only!) that, while there might be slight differences, most of the races age in a similar fashion. It might be completely wrong, and if so I'll change it right away, but looking at the anatomy of the races and such I imagine the lifespans are similar to Hyur/Humans.
Except Elezen, who clearly have an extra heart hidden in their huge necks.
