My husband practices the “bait your hook with a worm, wipe your hands on your jeans, and pick your sandwich back up off the dock and eat it” method. I’d gladly tie him to a chair and read him my microbiology book, but he won’t cooperate.
I’ve worked in chemical manufacturing for so long now staying washed up is second nature.
Before entering any manufacturing space, washing hands is a biggie.
Like your husband, I was born with instincts which protect me from the perils of over-sterilization.
