The high fuel to thrust numbers are kind of a given. However longer lifespans
wouldn't really help. If the mission was going to be so slow you needed that
many extra decades, everyone would just wait a couple decades until we could
build faster ships. Besides, how many decades could the crew stand doing
nothing in a little ship? How good would they be at their jobs after decades
without hands on practice? Who'ld volenteer for a half century of
imprisonment on route?
