Just imagine that for a second..."eternal life." You'd never be able to feel any sensation as you can now...and you'd never be considered "human" again, either, despite having all your memories, and having the brain of "the human you once were." Worst of all would be the fact that, knowing that you WERE human, and knowing what you would have then become, you couldn't even say yourself that you were "human" at that point.
And you'd have this problem for eternity.
No. No way to live...maybe just long enough to get revenge on some douchebags that desperately need a good shit kickin', but after that? Definitely no kind of life.
