Just wanted to give a shout out for Deep Springs College. This is a 2 year college where students work 20 hours/week running a ranch. (And as far as I can tell they don't have a lazy river). (and it could be a good choice for some gifted students?). 20 hours of ranch work per week is probably a great stress reducer.

It is men only - but maybe there are other schools that follow this "anti-lazy river" model? It seems like an interesting way to go.
