Personally I consider Immortality to be a Blessing and not a Curse like other people might think it is.
Sure Immortality isn't perfect, but what is? But if you're Immortal you could do things you know the average person couldn't do and survive in the attempt.
You would see how life and history evolve all around you and experience things you wouldn't have been able to if you weren't Immortal in the first place.
You would still be around to see future Inventions, Advances in Science, maybe see humans start to visit other Planets or even to colonize them like in the Science-Fiction Novels.
You would have seen and done things that by that time other people would only have read in History books or seen in the movies.
But the question is if everyone is going to be immortal then what happens?
Situation would be out of control since resources are limited and expenditures are limitless, water, oil, food, Land which already is scarce and due to multiple population explosions everything would be in extreme shortage.
People will turn to cannibalism, live on trees, professions will change, crime would rise, poverty, illiteracy would resurface.
But nonetheless it would still be totally awesome to actually be Immortal.
