Personally, I think that immortality does not make your life fulfilling at all. For starters, life would become boring after a while. There is only so much to do in the physical world, and after a time, you would be bound to repeating the same tasks over and over again, for eternity. Also, there would come a point where all of your loved ones would be gone, and you would have to grieve for them for the rest of forever. I am a firm believer in an afterlife, so living on Earth, is just one step for you in the "big picture". Being stuck here, would be almost torturous after a long enough time.

In the land of the immortal struldbrugs:

“If a struldbrug happen to marry one of his own kind, the marriage is dissolved of course, by the courtesy of the kingdom, as soon as the younger of the two comes to be fourscore; for the law thinks it a reasonable indulgence, that those who are condemned, without any fault of their own, to a perpetual continuance in the world, should not have their misery doubled by the load of a wife.

“As soon as they have completed the term of eighty years, they are looked on as dead in law; their heirs immediately succeed to their estates; only a small pittance is reserved for their support; and the poor ones are maintained at the public charge. After that period, they are held incapable of any employment of trust or profit; they cannot purchase lands, or take leases; neither are they allowed to be witnesses in any cause, either civil or criminal, not even for the decision of meers and bounds.

“At ninety, they lose their teeth and hair; they have at that age no distinction of taste, but eat and drink whatever they can get, without relish or appetite. The diseases they were subject to still continue, without increasing or diminishing. In talking, they forget the common appellation of things, and the names of persons, even of those who are their nearest friends and relations. For the same reason, they never can amuse themselves with reading, because their memory will not serve to carry them from the beginning of a sentence to the end; and by this defect, they are deprived of the only entertainment whereof they might otherwise be capable.

The language of this country being always upon the flux, the struldbrugs of one age do not understand those of another; neither are they able, after two hundred years, to hold any conversation (farther than by a few general words) with their neighbours the mortals; and thus they lie under the disadvantage of living like foreigners in their own country.”

This was the account given me of the struldbrugs, as near as I can remember. I afterwards saw five or six of different ages, the youngest not above two hundred years old, who were brought to me at several times by some of my friends; but although they were told, “that I was a great traveller, and had seen all the world,” they had not the least curiosity to ask me a question; only desired “I would give them slumskudask,” or a token of remembrance; which is a modest way of begging, to avoid the law, that strictly forbids it, because they are provided for by the public, although indeed with a very scanty allowance.

They are despised and hated by all sorts of people. When one of them is born, it is reckoned ominous, and their birth is recorded very particularly so that you may know their age by consulting the register, which, however, has not been kept above a thousand years past, or at least has been destroyed by time or public disturbances. But the usual way of computing how old they are, is by asking them what kings or great persons they can remember, and then consulting history; for infallibly the last prince in their mind did not begin his reign after they were fourscore years old.

They were the most mortifying sight I ever beheld; and the women more horrible than the men. Besides the usual deformities in extreme old age, they acquired an additional ghastliness, in proportion to their number of years, which is not to be described; and among half a dozen, I soon distinguished which was the eldest, although there was not above a century or two between them.

The reader will easily believe, that from what I had hear and seen, my keen appetite for perpetuity of life was much abated. I grew heartily ashamed of the pleasing visions I had formed; and thought no tyrant could invent a death into which I would not run with pleasure, from such a life. The king heard of all that had passed between me and my friends upon this occasion, and rallied me very pleasantly; wishing I could send a couple of struldbrugs to my own country, to arm our people against the fear of death; but this, it seems, is forbidden by the fundamental laws of the kingdom, or else I should have been well content with the trouble and expense of transporting them.

I could not but agree, that the laws of this kingdom relative to the struldbrugs were founded upon the strongest reasons, and such as any other country would be under the necessity of enacting, in the like circumstances. Otherwise, as avarice is the necessary consequence of old age, those immortals would in time become proprietors of the whole nation, and engross the civil power, which, for want of abilities to manage, must end in the ruin of the public.

I would hate the notion of living forever in an earthly body.

Well, Ive been scanning through most of the comments on this one and have noticed a little trend. You guys want everyone to be immortal. Okay well if we were all immortal then we would have some serious issues. Maybe it'd work if we found other planets we can live on or something but with our wee little earth it'd never work. People would have babies, babies would fall in love when they grow up, they'd want to have babies and so on and so on........Hmmm.....Random thought but if everyone was immortal then there'd be no abortions right?? My brain is starting to hurt.

My thought....If you aged there'd be no point. Aged like normal people. If it was a slow progressing aging then I could see it. If you lived forever aside from everyone dying around you, what would you do with yourself? Eventually the novelty of immortality would wear off and pushing yourself to your limits would be no longer fun. So your alive for 200 years. Assuming the world will still be here then....What are you gonna do? Unless everyone lives forever or is much more allowing then you'd have to cover your ass all the time. Lie cheat and steal. Sounds like kind of a sucky existance all for the not dying part.

if you where imortal what would you do? what do you have to live for? could you watch everyone you love die? could you spend the endless years alone with the fear of getting close brcause you might lose them? what would you have to believe in? those are the questions an immortal ask and what do they hear in return? silence

wow have I thought about this over and over again..
I think there could be two ways to look at it.
If you had to live forever you would have so many advantages, you would know more about human behavior than anyone else, making it easier to predict peoples reactions and giving you more time to make a success of your life. You would constantly have fresh starts in the sense that people u previously knew would no longer be alive therefore giving you the opportunity to change peoples perception of you, constantly meeting new people.

On the other hand you would be extremely lonely. What if you had met your soulmate and they die? you would then feel you have lost your purpose of living. Eventually after living so many years you would lose your purpose of living, making it difficult to get up every morning. Eventually you would feel as if you had seen, heard, smelt, felt it all. what else could there possibly be once you have experienced it all?

then you ask yourself the question, how long is forever? is forever possible? NO. nothing is forever. Earth itself is not forever, therefore you cannot live forever, so would you live until earth is destroyed, experience the end of humanity? and that's a completely different topic
