Environment vs. drugs.   What to do with a restless mind?

I recently read an article from the New York Times that suggests that originally we were meant to be a bit distracted and that distractedness has helped  us evolve by being better hunters and gatherers.   Apparently there is a gene that is correlated with people with better nutrition that is also a marker for ADHD.

Maybe sometimes all that is needed is a change to a more stimulating environment.
