Today, by comparison, we have at least peripheral contact with sometimes hundreds of people on a daily basis.
We’re part of larger social groups, neighborhoods, families, social media cliques and work groups that, unlike the Paleolithic model, rarely overlap. We may not spend all day with these people hunting and dressing a kill, but we field countless micro-demands (e.g. favors, questions, invitations, feedback, etc.) from them in addition to more substantial requests and responsibilities.
