Well, This is a thread started because I had a theory on why elves don't get sick, and a few people asked me to share it. And here you can talk about your own theorys!
Anyway, my theory deals with the idea that the do get sick, but for one, sense they are elves, and elves stay clean, they probably didn't have all that much exposure to many harmful pathogens, and if they did get sick, it was probably very mild. Now, they also have very long life spans (Tolkien said himself that the elves were not completely immortal) which makes it possible for them to strengthen their immune systems, along with becoming immune to things such as chicken pox, measles, and mabye even strep throat. But for things such as colds, they most likely catch them once and a while, again, probably very mild, and as I've said before, they would now have very strong immune systems, and therefore making them even more mild. And due to the elves extensive knowledge on herbs, they would probably be able to get over them very quickly.
Well, there it is! Feel free to share your thoughts.
