There's actually this one really bad episode of the Twilight Zone that applies here, even if it involved cryogenics, not relativity.Relativity makes you stop aging, why cure it?
Even better. Relativity effects are based on how fast objects move.I just wonder how, for instance, Star Trek has a universal star date. There's no such thing as a "correct" frame of reference. Basically, it means they just picked one to prioritize above all others. Those bigots.
