Some human behaviors that may contribute to decreased exposure to microbes include:
- Sterilizing cooking utensils or using disposable dishware
- Frequently sanitizing surfaces
- Living alone
- Frequent showers
- Always washing hands (sort of incessantly)
- Wearing gloves
- Working in a highly sterile environment
- Wearing surgical mask to prevent inhalation of airborne bacteria
- Having a low-bacteria diet (foods such as pasteurized milk and yogurt, well-cooked meats, frozen/canned/dried fruits and veggies are typically low in bacteria)
