The afternoon nap, it turns out, provides a serious benefit to memory.
Subjects in the study were trained in a few memory tasks, and then half of them took 45-minute naps. Those who learned the tasks effectively prior to siesta time retained the information better than those who stayed awake. So, after your next long meeting, or information-intensive conference call, head to the nearest couch for a while. For the good of the company, of course.
