if 8-year girls will be put in some sort of stasis or what ever technology that will prevent biological body systems decay, when wake up that girl after like... 10 years, will be she account adult? by the law... Yes! Even is sound awful, danm reality sucks...
if somebody put themself in stasis or whatever and stay like that in 50 or more years, then it will biologically like it was on moment he was before stasis, but absolute time will be different and that mean... duh... whatever mean he will be young but spend its time 50 years and nobody now dont know him, he must start all from beginning, new friends, learn new technology, other people psychology, new work, is it worth?
