Yes, the Mer (Elves) do live longer then humans. Except Orcs or Orsimer as they got the cursed. I will explain (Hopefully I explain correctly). One day Arkay cursed the Nords making them live around 6 years. Then one of the Nord gods lifted the curse from the Nords and cast it upon the Orsimer which had been living as long as any other type of Mer but the curse shortened their life span. So the only three remaining races of Mer that live the natural length are Dunmer, Altmer, and Bosmer. Orsimer have a reduced life span and the other Mer, the Dwemer, Aldmer, Falmer, and Chimer are now extinct or basically extinct. The only remaining Dwemer or Dwarf is a male that has the "Divine Disease" and about what happened to the Dwemer,
Spoiler I believe that they became the golden skin of the Numidum, their god
, the Falmer or Snow Elves are believed to have been wiped out by the Nords, the Chimer or
Spoiler Changed Folk were transformed into the Dunmer by Azura
, and the Aldmer which are the original Mer have now become the other types of Mer.
If I am incorrect about any of this info please let me know.
