Hobbits mature later and live longer than modern Humans. They are probably good for a level (or half-level if you go in for those) of Extended Lifespan.

You have Dwarves starting to age at about 200, and dying by 300 or so. In The Hobbit Thorin & co. often mutter "if I were a century younger", which to me implies that they are active adults for many centuries, not just one or two.
