Re: starship-design: Suspended Animation

An acquaintance of mine underwent an accident last year and the doctors chose to put him under an "induced
coma" to improve his chances of recovery. I was told that this also lowered his metabolic rate somewhat. This
seems like a start.
Also, I remember reading (about 10 years ago) about promising research was being done on mammal - not
amphibian - hibernation. My internet searches have not revealed much about the progress attained since then.
If research has not been suspended, I _suppose_ that another 50 years of it could bring about enough
knowledge to induce multi-year long periods of "suspended animation" or "hypo-metabolic state". If a 9:1
ratio of "sleep time" to "waking time" can be obtained by then, the ship could function with "only" 20% of
its complement "awake" at any time. I have the impression that, say, half of those would be undergoing
exercise and recovery (or prep for their next sleep fase). Would 10% or 8% of the complement be enough to
function as crew?
