How long do Viera live?

[Daralii]

I have a timeline for my character for roleplaying purposes, and she's 88, which amongst the Viera still makes her essentially a rambunctious teenager, despite living through and serving in two wars. Long-lived races are fun like that.

I sort of figured that age 200 would be equivalent to age 35 or so for a modern human, with 400 being equivalent to 70, and any time beyond that being 'elderly'.

The Wandering Dramaturge makes it seem like 240 is the normal expected lifespan. From what he says about their appearance of youth, I'd guess that everything past 200 is considered somewhat elderly. Viis might live longer than Viera or Elves might have shorter lives than Elezen from what Almet says.
