Lifespan/age of different races?

[Iscah]

Miqote have the shortest life span of all the race based on what the lore book says.

There's nothing in the lorebook about Miqo'te having shorter lifespans than other races. Certainly not in the race profiles, anyway.

I don't know where that idea comes from unless people are just extrapolating from their lifestyle and assuming that more of them probably don't live to old age.
