I remember seeing a movie back when I was a kid that revolved around the idea of a punishment that revolved around "age payment." If you committed a horrendous crime, rather than lock you up, they put you in a machine and age you 50+ years.
One of the main characters in the movie gets framed as a child for a crime, and he is then aged to about 40ish. The movie deals with the concept of this type of punishment, as well as his ability to cope with the adult world with the mind of a child. The idea was pretty interesting, but I do remember it being a "B" type of movie.
