Kevin was famous for being mistreated by the DoJ and writing some books which were perhaps not particularly true in hindsight. After he got out of jail and rejoined the community he lost a lot of respect for being himself, though it's not impossible that years of imprisonment and a long time in solitary had some permanent negative effects. In other words... you shouldn't envy Kevin's life.

For the rest: nothing's stopping you from having fun, regardless of age.
