The packets I carry are hand sanitizers and I have a small bottle of the liquid in my purse during the winter.
I have boxes of surgical masks.
I never go to Walmart - too many people in there and in winter with people going to the pharmacy, the store is a bacteria’s/virus’s dream.
I go to Kroger where I seldom see a kid and there is seldom a crowd. Tuesday before Thanksgiving was the most people I have seen in there.
So, keeping healthy, depends a lot on location, location, location (just like in real estate).
Bravo for you. I wish you complete success in your efforts to avoid the flu!
