re: If wearing a Mask keeps Covid from being transmitted, why are we shut down?

Wear a mask indoors. Limit time spent indoors. Limit the density of people around you and the contact time with them. Clean your hands often. You can still catch it with a mask but it probably helps somewhat and you cant be a super spreader as easily.

Outside....chances are very slim you catch this. Every place should be figuring out a way to get outside somehow and move on with life a little differently.

Mask indoors makes sense to prevent you from sneezing or coughing as an asymptomatic carrier to a bunch of people.

Outdoor church should be the summer norm. Outdoor restaurant seating should be the summer norm. Beer gardens. Turn those parking lots into spread apart seating. Beaches and boats all good. Swimming pools probably fine. Just get into open air.
