Social distancing is here to stay for much more than a few weeks. It will upend our way of life, in some ways forever. We all want things to go back to normal quickly. But what most of us have probably not yet realized—yet will soon—is that things won’t go back to normal after a few weeks, or even a few months. Some things never will. What counts as “social distancing”? The researchers define it as “All households reduce contact outside household, school or workplace by 75%.” That doesn’t mean you get to go out with your friends once a week instead of four times. It means everyone does everything they can to minimize social contact, and overall, the number of contacts falls by 75%.
