How about this one:
Instead of living forever in the same body, what if we figured out a way to download all the information stored in our brains? Then, once our bodies were getting a little run-down, we could copy and paste our brains into a new, cloned body, exactly like the one we have now, just younger. You could back up your brain every few months in case of accidents or otherwise untimely deaths. In this way, your brain lives on and you don't have to worry about the body degenerating.
