What we instinctively do is mark our personal territory, much like our dogs would, once we’re in the presence of others. And It’s not because of the condition of the world we currently live in. Social distancing has always been around.
We always habitually avoid getting close to people at work, at home, on the subway or the elevator, especially from those we’re unfamiliar with.
This personal space we seek acts as an invisible shield, offers protection, as we signal personal and social warnings if someone is too close.
