What do hunter-gatherer groups foraging on foot for food have in common with sharks and honeybees?  What do they have in common with you and the way you move about? 

According to anthropological studies, we follow a similar mathematical pattern of movement.  It is “called the Levy walk…a series of short movements in one area combined with a few longer treks to more distant areas.”

(Now you know what to do with that GPS wrist-watch that was under the tree.)
