Practically, one could:<p>* wash hands, and frequently (but you don&#x27;t need an antibacterial soap -- they&#x27;re bad for fish)<p>* use your well-seasoned wok&#x2F;cast-iron skillet and not wash it with soap<p>* eat your fermented foods (from funky cheese to kimchi)<p>* eat things straight out of the garden without washing as long as there is no visible raccoon poop<p>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&#x27;t need to sanitize every part of yourself every day.<p>The only area in my life where I&#x27;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.
