See, I've never quite been able to grasp the hesitation or outright fear of immortality. The most common excuses I've heard are the very ones that you stated: that everything would become old hat, and that all the people you know will eventually die.
But the thing is, the world is constantly changing! So long as the human race continues to progress, there will always be new things to do! New books to read, new shows to watch, new sports to take part in, new technologies to utilize! Hell, even assuming the world suddenly became totally stagnant, it would easily take you hundreds of years to read every novel, view every piece of cinema, travel the globe and see everything there is to see. And, barring some horrific cataclysm, there's always limitless expanse of space yawning out before us!
As for the fleeting nature of the relationships you would form... At first it would be jarring, even depressing to watch all the people you've known and loved grow old and die, only to realize that you won't be able to experience the same. But like experiences, there will always be new people to meet. New friends, new mentors, new pupils, new lovers; an immortal person would eventually choose to focus on the fact that they will be able to meet thousands upon thousands of truly wonderful people over the course of their limitless existence. When they hit the lowest of the low, there will always be the knowledge that they will live to see the day when things get better again. One of the early Sandman comics deals with this idea to great effect.
Thing is, I'm not scared by the idea. I'm just wondering who in their right mind would want to be an immortal being. Sure, you can do all this fantastic stuff like transcend the myriads of time itself and read all sorts of books, watch all kinds of movies, TV, read millions upon millions of articles on the internet - assuming we're all gonna be around for when it does hit the fan - but what then?
Let's take into account that this sort of thing has been tested and proven in the past, what with the tragic villain, Zasalamel from Soul Calibur 3. According to his bio (as read here
), it states that he was technically an immortal being due to a spell that was woven over him by his own doing. As a result, it prevented him from finding his own death. Or even if he did in fact die - whether it was by his own hand or not - he was only reborn into another body with the same memories and physical features of his last life. Pretty much a human phoenix, if you will.
But that's crossing hairs.
I eluded to the question of "what then". Assume you could be that immortal being, you do all do this, write an on going series of books to catalog all of the world's events for all eternity, but again. What then?
What does a person do like that after all is said and done? However, I will give you an out on the progression of humanity, that as long as it continues to exist in this time frame, humanity will continue. But assuming there is nothing to humanity left except for that one immortal person, what would he or she do? Surely, they can't meet their own end, because no matter what they do, they cannot
die naturally nor can they kill themselves.
The truth of the matter - as I stated previously - is not only would it be immensely boring and nothing would be new to you not to mention lonely because everyone you knew in life died but not you, but there was also something I forgot to mention. Your own temperament would eventually sour into something leaning towards apathy or possibly even misanthropy. So then, the only solution would be to hide away for thousands of years never to be heard from ever again so no one would be able to discover how you became that way.
