@scoop thanks for you reply and the video. I will definitely watch it. There is tons of dust at the studio I go to. I've been wearing an N95 mask the last 3 weeks I have gone for classes. I've also been masking while working with potting soil, or gardening. The cooking and washing dishes really struck me as over the top, but it made sense to me. Not sure what I'll do there, yet. Our water heater is turned up really high, but I don't know the exact temperature. I'll check on that. We're supposed to go on a beach vacation next week and I'm afraid to go to the beach or get in the pool. Ugh.
