There's a setting where no one knows the age limit of goblins because they always die from actions (often their own). I can easily see that being true in DF where people are more likely to die from monster attacks, evil necromancers, and giant stone golems under their villages than old age.

I think officially speaking age doesn't matter because age damage is dealt relatively instead of directly, but I don't recall the page number for that.
