I always wipe shopping carts down when I get there but the one I leave with is always different. The baggers always have an empty cart at the ready so they don't have to wait to start bagging your groceries until you are done unloading. Never thought about that until just now, that no matter that I'm wiping it down on the way in, I could be picking up germs on the way out.
yikes.
My recently diagnosed low lung function does have me concerned about myself. But I guess no sense in worrying or panicking. That just produces stress that compromises the immune system too.
