There is no problem at all. Wanting to live forever is just your body's primitive instinct, and you should be intelligent enough to understand that people don't need you, or anyone, being around for longer than you will live already. Just look at the current old people - how they drag the whole progress, the whole society back. Now Imagine what would happen if everyone would be old - stagnation, that's what. Human brain is not evolved enough to keep being fresh for so long. After some time we slow down our learning rate because we have already learned much things. If everyone would live forever we would stay at the exact generation the "singularity" would be invented. People need to die in order for everyone to push things forward.
