One more question, since I can't find a solid answer:

How long, roughly, do Bosmer live? I'm considering my character starting at 40 years old. I understand Mer hit adulthood around 20-ish?

From what I understand, elves (not including orcs), live up to 200-300 years old on average. That's assuming no significant life-extension, and with advanced magic, people like Divayth Fyr can live indefinitely. 

They reach maturity around the same age that humans do, as shown by Barenziah and Ayrenn. However, I imagine some elven societies may take advantage of their longer lifespan and stay in school for an extended period of time.
