Sigh-Fi

Still a good deal. You don't have to colonize a planet, you're 50 biological years younger than you would have been and you have knowledge of that past that may have been lost. Your immediate family is probably with you, so you just time traveled and brought your loved ones, which is basically unheard of even in fiction. On top of that, you're the kind of person that would jump into the dark to see what was there, so now that there's FTL you can do that on a grander scale. This is a good deal all around.
