Forum:KB:Humans in a GFFA

I've noticed that Humans in the Star Wars universe tend to be long lived. I look at the cover art for novels, and Leia has aged considerably better than Carrie Fisher. I tried looking up in the "Human" and Humanoid" articles, but it doesn't mention a general life span. By the time of the beginning of the Legacy era, Luke, Leia, and Han are getting pretty old, but all we see of the effects of aging are gray temples and slightly lined faces. On top of that they still are pretty physically capable for people in their seventies, even after the considerable hard living they've had.

So are Humans in the GFFA longer lived? Even those without the Force are still pretty darn healthy galivanting around the galaxy in their 80s and 90s. Is there a source that states Humans lifespans?
