Immortality

I sometimes ponder over the possiblity of human immortality. Yes, I know its possible scientifically, but I don't think most people would agree with me. I know its only a matter of time before a way is found of increasing the average lifespan of man to several times more than what it used to be.
With cryonics now we have people preserving their bodies with a hope of being raised back to life. But the thing bothering me is that I don't think humanity is ready for immortality at this stage. I'm guessing we have to become more peaceful first before we can make good use of our immortality. Time would tell
