The interesting thing about the treatments is that nobody reacts in exactly the same way to them.  Most people start aging at an effective rate of 1 year for every 10.  Some age slower, some faster.  The really old can seem to get a lot younger too.  They’re still old, but they’re healthy old.  And that can make all the difference in the worlds.  Most of us should be able to live for centuries.  And the effect of that on society is crazy amazing.
