“Just as campfires resonate deeply across space and time, watering holes have an equal status in the pantheon of learning places. Virtually every hominid on the planet has, at one time in its historical existence, needed to gather at a central source for water. During these trips to the watering hole, people shared information with their neighbors—those within their own village, as well as those from neighboring villages and travelers on their way to or from a distant village. The watering hole became a place where we learned from our peers—where we shared the news of the day.”
