So many people hold the view that death gives life meaning; without it, life's purpose, enjoyment, value will diminish outside of mortality. I've come across those who think immortality is a tortured experience constantly losing the ones you love, never being able to die. I suppose that is why when humans write tales of immortal beings they add a death clause. They conjure up methods in which to kill these immortal beings simply because humans can't fathom a being living forever. They can however fathom a being who has the ability to live long lives, as long as, they stay away from those who have studied the arts in how to kill them.
Humans assume living forever will be tiresome yet I say they look at it the wrong way...
