Universal masking will slow the spread of this virus and FINALLY we have some direction from President Trump that he wants us to wear masks. He said wearing a mask is not political; it is patriotic.

I take my cues from science, not politicians. Your cloth mask can block larger droplets from emitting to others, but does very little to block very small particles. Your breath is moist, in a short time the pores of the material become blocked by moisture and then your breath is exhaled around the edge of the mask. Cloth masks even when dry have pores much to large to block the small particles. This study by 2 experts looked at 52 studies of masks and found little evidence for efficient source control.

DR Fauci in a recent interview stated he would not get in an airplane or enter a restaurant, mask or not. Why do you think he says that?
Masks are better than nothing, but are not a replacement for social distancing. This is why I don't enter buildings other than home. Not worth the risk mask or not. I realize that people who work have no choice, but most of them are much younger than I am.
