Maybe Bombadil isn't a "living thing". It is considered by some that he is one of the Maia (like Gandalf) from the creation of the world, but one who went native and stayed in Middle Earth instead of associating with the Ainur in the west. (Do I get Colbert brownie points for this one?)
I've heard from one of the relatives of a nurse at the Goshen hospital who voluntarily quit (wasn't one of those fired). His primary reason for quitting was because the doctors aren't required to have the flu shot since they are private contractors and not hospital employees. Several of the doctors were declining to get the flu shot and he felt that the hospital shouldn't have the right to dictate terms to him that they wouldn't/couldn't even enforce with the doctors that worked there.
One word: Titles.
It's not about the character level in GW2, it's about getting all the titles. Of course once you've done that, then yeah, it's just like any other game you've ever completed. Everything comes to an end at some point.
