I wear a mask while I go to the store to get food and other needs. I also keep a distance from others, use hand sanitizer when getting back into the car and do hand washing, etc. when arriving at home. I had the medical N95 masks leftover from a trip to Red China back when SARS was over there. I had put the ones not used aside and searched my storage area until I found them. I’m 73 and in the high-risk range.
You are also wise.
