Because it never happened. What person is 90 and looks 20?

If we are playing thought experiments it is fine but right now there is no reason to think that is possible. This is what people are telling you. They do not lack imagination, they say it does not seem likely. It is fun to fantasize about as a science-fiction topic though.

The 90 to 20 contrast may be too large a spread to be anything but hyperbolic at this time, however:

when seeing someone like Larry Ellison speak and move, it is very clear that dedicated optimization has major benefits and productive results.

Show a recent interview of Ellison to a random person and ask them how old the guy is - the responses I often get from people are estimates in the 40-50's range.

While obviously this is not '20', it is still almost a halving in how old one is perceived (if you didn't know his temporal age, go watch a few minutes of a recent interview, then guess how old he is, then look up his actual age). Though this comment may bias one to guess on the older side, that's why we can blind the experiment by asking someone else you know.

So, plastic surgery, and hair dye?

Islands have been known to be sources of youth.

Nah he’s got the youthful quickness to go with it
