If you're immortal, then the "climb on a starship for 1000 years" deal starts looking a lot better. That would open up a lot of new resources to turn in to living people with lives to experience.
(P.S. we're not anywhere near close to using our current resources completely or efficiently, so please stick around and help us get a little closer!)
Your starship would have to be something similar to Rama[1] for me to even consider it. A thousand years on anything similar to an upscaled contemporary spacecraft sounds like torture.
