It also means that many of us might get coronavirus and be fine, or, as with the majority of coronaviruses, we get a cold. Coronaviruses can live on surfaces for a few hours in mucous droplets, etc. But they generally don't survive long term outside of a body. That's why hand-washing and any kind of face mask/covering are helpful. The hand-washing continuously removes the viruses your hands may pick up. And, in case of accidental exposure prior to hand-washing, a face covering will prevent you from inadvertently touching your mouth or nose, which is the usual entry point.

Great point about some of us carrying it and being fine, never thought of it that way!!!
