Get a grip! Hold your tongue! Shrug it off! Exerting willpower seems like a mental task, but it turns out that our physical bodies are very much involved in keeping us in line and acting appropriately.

This may make us better and healthier consumers, but it also means that we need to be mindful of the tension patterns we create with these subtle, repetitive clenching habits.
