Practically, one could: * wash hands, and frequently (but you don't need an antibacterial soap -- they're bad for fish) * use your well-seasoned wok/cast-iron skillet and not wash it with soap * eat your fermented foods (from funky cheese to kimchi) * eat things straight out of the garden without washing as long as there is no visible raccoon poop etc. It is also possible to use different gradations of cleaning power for your body and house: bleach kills everything while vinegar and baking soda clean most things just fine; some soaps are less harsh than others. Showering regularly is a blessing in high population-density areas, but you don't need to sanitize every part of yourself every day. The only area in my life where I'm fanatical about sanitization, in fact, is brewing beer. There a certain outcome is desired and my usually carefully cultivated lackadaisical attitude is not appropriate.
