Well, maybe not mastered, but I did just read a book on it.
Now, courtesy Instapundit, we learn Nordic walking significantly reduces depression symptoms in as little as five weeks, trial finds.
Nordic walking: You know, walking with poles, like you’re cross-country skiing, not like you’re a wizard leading a party on a quest. Which would probably also help with depression unless your scrying indicated your quest was doomed to failure, but you have to try anyway.
Remember NordicTracks? They were a staple of television advertising at one point. They’re still around, part of a fitness conglomerate which has rejected my applications several times. But NordicTracking in your hovel is probably not the part that fights depression. One wonders if being part of a supervised study, thinking that you’re part of something greater than yourself even for a brief time, is enough to lift a bit of depression. But I’m not a researcher, just a blogger.
