I'm also interested in what 'kind' of immortality. Our bodies change with age, they deteriorate and where it, which is the reason we eventually die (I mean natural causes, eventually, it becomes too hard for your heart to beat and pass blood to the rest of your body, and your gone. Now, a bullet would be another story), so if we'd live forever, then we'd age, and eventually we wouldn't be able to move, just live. If we weren't to age, then we'd be cut out of civilization. If I didn't age for five years, my family wouldn't just be suspicious, they'd start calling the cops, and following me around, and paying my friends to wear a wire, and...oh, I've gone far enough, but most normal people would comment me on my looks. After ten years, people'd start to get suspicious (and my family would kidnap me for questioning, and, as I'm assuming, so would the government). After fifteen years, the government would want to talk with me, and if I wasn't gone by twenty, I'd probably be in some kind of government experiment. Also, besides normal people, you couldn't have a family without leaving it every couple of years, and you can't tell me you'd be fine with that (you immoral, selfish bastard). And if you did have/get a family, you'd have to watch them die before you eyes. That'd be terrible. Also, you can't tell me boredom wouln't get to you after thousands of years. And what about when the Earth would be destroyed? You'd float in space forever. But what's my final answer? In truth, yes. If you're talking immortality, you're talking invincibility too. Think about it. If you're immortal, you live forever, and therefore cannot die or be killed. I'd go around jumping from building tops and if I fell, no biggy, I'd be OK. Plus, I'd carry a stock of grenades, and two fully loaded pistols. If I got into an argument with someone, I'd just hold them down and cook a frag in their mouth. And if a friend and I were really pissed at each other I could fake my own death. Sweet ^.^ Another thing, I could kill hundreds of people. It'd be like a video game, except there's never an off button and you never die. Also, I'd go sky-diving without a parachute into a pool full of lava with invinicible, laser-equipped sharks inside. While doing a girl with AIDS (if I'm immortal and invincible, then so are my bodies defenses, so I couldn't contract any diseases/viruses/colds). It wouldn't get boring, because I could do ANYTHING I wanted, anywhere.
But really, we're not that far enough from immortality. Think about it: if I could dodge enough bullets and get enough liver transplants, I could live potentially thousands of years. With advances in modern technology such as gene therapy and stem cell research getting closer every day, who says by the time I'm 70 or 80, I won't be able to live to 1000?
