Comment by Burkan on Existence - Chapter 9

@Burkan Ultimately, They can live forever, but that doesn't mean they can't die. The term for their inmortality is the fact that they won't die as longs as there is no factor that can cause them dead, such as a predator or a disease, but they won't die otherwise.

@Burkan  they don't just age
They can die if they are eaten by other animal or kille
