10The Elves Do Not Age
Elves don't age physically and they do not die from disease. The only real ways to kill them are strong negative energy and violence, although there are probably magical ways to kill them, as well. They have healing powers shown in the movies but if you notice, none of the
Elves ever got sick or seemed to die from old age.
They could "die" of old age, but as explained, they would kind of fade out so that they would become ghosts. If they became ghosts, they wouldn't be able to live again unless they took over a living body through force. Their concept of an afterlife was also different. It seemed their soul would go on to a different place from humans, but they also had to follow a strict path after they passed or it would be bad.
