Will we ever live forever, Will it happen in my lifetime?

Our physical bodies are purpose-built to be finite, so we can strengthen our spiritual bodies. Our spiritual bodies are already infinite! Even if we could prolong our physical lives, chances are we'd just live longer in an old body. I don't want to be 80 years old for 40 additional years. There are so many kinds of cancer, we would all ultimately sucb to some form of cancer. No, thanks.
