Someday, they're going to invent stasis for just this sort of shit.
Standing still waiting for young actresses to be not so bloody young.
Sure she's 18 now, which is still too young, but 3 years ago when we anticipated that she might be amazing one day when she's all grown up, it was still creepy for us to letch over even 25 year olds, gods forbid 15 year olds.
Deepspace flight colonizing distant worlds my ass.
Of course sometimes you spend 10 years in stasis waiting for a specific actress to turn 30, but you come out only to find that she's dead from living life too hard.
