how long do elves live lotr

The lifespan of an elf varies depending on which series you're referring to. In J.R.R. Tolkien's Middle-earth, the lifespan of an elf is considered to be indefinite and they do not age past adulthood. However, they are susceptible to injury and death like any other living being. The lifespan of an elf in the "Lord of the Rings" movie series is also very long, but not quite as long as in the books. They still don't age past adulthood and are generally very long-lived.
