Restless Leg Syndrome

The Freakonomics guys have a post on Restless Leg Syndrome. Virginia Postrel comments

If something is a “disease,” it is worth treating. If it isn’t a “disease,” you should just live with it. But why? Why not treat a biological condition you just don’t like? (I’m assuming that you are directly or indirectly paying for the treatment.) We don’t have to call Restless Leg Syndrome a disease to acknowledge that it disturbs some people’s sleep and that those people would like relief. Contrary to what you may have heard, the only sort of character suffering builds is the ability to suffer–a useful ability in a world where suffering is the routine nature of life but not a virtue that makes the world a better place.

RLS is hardly the worst thing that one can have, but why not use all that modern society has to offer.
