it is interesting to think of the psychological implications. i don't think they'll actually be able to make anyone handsome in 20 years honestly. i mean there will be a lot more stuff for kids for sure. remember 50-70 percent of beauty is actually just youth. so if you're past 40 you ain't gonna look that great no matter what they do to your jaw etc..
i can't really see how they'll reverse aging though. i mean that would require really weird s**t like cloning skin and then having microsurgery to put you in a new skin envelope. I mean i suppose it's doable and really cost-prohibitive. But i bet there'd be weird tell tale signs of seeing like an 80 year old in a young man's body. like he'd still have really s**t breath or something or weird sunken in eyes.
yeah there's 50 thousand factors you have to account for, we aren't even close to accounting for everything that makes us age... but if you're immortal then time isn't really an issue lol. and more importantly if you can get to the root cause of aging and halt that (I have no idea what that is I'm not a scientist, cell reproduction?), you may just be able to stop everything else. of course the wear of the environment over time will take it's toll and may require medication or something of some sort, but if your cells are kept in a constant state of 'youthfulness' then they are more prone to quicker healing. I'm just blowing smoke here, but theoretically it does seem possible to stop aging, it's a matter of addressing the root cause rather than trying to stop wrinkled skin, sunken in eyes, etc. which are all just a byproduct of the cells of course.
and if time isn't an issue, there's always the possibility of discovering reverse agin
this is all optimistic thinking. I find God too preposterous to believe in, so the future of science provides more comfort to me
