Here is what I want to know. At what point do we cross a line from sanitation into germophobia?
I wear shoes in my home. This is good for my feet and practical for my life. If ever I have certain hoped-for building materials for my entire residence, I may change my mind and consider barefoot indoor living. I have not identified appropriate options for mid-winter in snow country, when indoor floors are cold, but I will continue to consider barefoot indoor living, just in case something becomes available.
I don't think we will ever make the world clean enough. We cannot continuously clean all surfaces. If we did that, we would not do anything else. We would be like Monk, or Sheldon Cooper.
As long as medical spaces are properly cleaned, and food workers wash their hands or change their gloves as needed, I'm good. My world is clean enough for health, though not clean enough for the Inner Perfectionist. All is well anyway.
Nature does not hurry, yet everything is accomplished. - Lao-Tzu
