"oh god, please dont make me immortal!" i don't want to witness the degradaton to our planet via urbanization, pollution, destruction of ecosystems...ugh
I would love that. I wouldn't just be slightly happy, I would be ecstatic. I'm not afraid to die, but if given the opportunity, I would definitely choose to live forever. Especially if it meant I also got to retain my youthful energy and appearance. Being "unkillable" would be an added bonus, it would probably lead me to take a lot of unnecessary risks. I think I could use that to my advantage to serve both my selfish as well as my altruistic desires.
Just think about it: you could fight crime, without having to worry about getting killed in the process. You could capitalize on your newfound immortality for financial gain (work as a stunt double, a daredevil in a Vegas show, race car driver, maybe have your own reality series, become a UFC prize fighter, whatever). Living forever, you would get to see the future. Imagine all the wisdom you would accumulate over the years. Imagine all the people you could meet, all the things you could do with your life. You would never need to worry about making a "bucket list" of things to do before you die, since you wouldn't die. You could jump off of buildings, drive as fast as you want, eat, drink and smoke to your heart's desire, whatever you wanted to do. If you are a person with evil tendencies, you could use your newfound power to become a notorious and unstoppable villain. You could walk across the freeway if you felt like it. You could essentially end any war singlehandedly. The power would be awesome.
Ask God to take back that blessing.
I don't want to be immortal.
Anai's answer reminds me of this passage from Nietzsche:
Companions the creator seeks, not corpses, not herds and believers. Fellow creators the creator seeks--those who write new values on new tablets. Companions the creator seeks, and fellow harvesters; for everything about him is ripe for the harvest. -- Friedrich Nietzsche, "Thus Spoke Zarathustra"
I'm atheist, but taking your question as the hypothetical it was intended to be, I would conjecture that god was looking for companions. The notion that mortal, fallable, irrational humans were made in god's image, if god actually existed, is laughable. The mindset and worldview of an immortal is fundamentally different from that of a mortal. Think of Dr. Manhattan from "The Watchmen" movie/graphic novel. When you have literally all the time in the world, worldly things become less important. As you pass through the eons and watch civilization after civilization rise and fall, there arises a sameness to them, and concepts like nationality become silly and trivial. As you interact and have relations with millions of (mortal) people over time, so too does a sameness arise in your perception of humans. Which is not to say that you couldn't have satisfying relationships with them, but eventually it will not be such a hardship to lose them when they die.
When you're immortal, you have much more time to explore being yourself. If you want to spend 10,000 years goofing off and living a hedonistic lifestyle, that's OK, because what's 10,000 years compared to the countless trillions that lie ahead? You could invest a single dollar at 5% interest and given enough time (and assuming you were the only immortal), you'd become the richest person in history just from the interest it earned. When you are immortal, there is no limit on the amount of time you can spend learning new knowledge. You would have near absolute freedom to be whatever kind of person you wanted, but the kind of person you'd become as an immortal would probably bear little relation to the kind of person you wish you could become as a mortal.
In case you haven't guessed, I've spent a lot of time thinking about what kind of existence I would lead if I were immortal. And yes, I would relish the opportunity to live forever, to watch the rise and fall of civilizations, to be a part of mankind's evolution into a truly mature species. So what would my _immediate_ reaction be upon being turned into an immortal by some god? I guess I would have to say, elation.
I would beg him to undo it and let me age naturally and die like everyone else. Imagine watching everyone you love die, yet you have to continue on. I imagine I would end up rather bored and tired of everything. I fear death, but given the choice I would pick death over immortality.
