Unless maybe you have TL10 Rejuvenation tech as in Bio-tech. Lifespans become indefinitely long if you do.

You could sue rejuvenation plus semi-realistic hibernation tech to keep the crew alive but "sleeping" for as long as the ship's self-repair systems will hold out. Very long trips could be survived that way and high speed propulsion wouldn't be such a necessity.
