A common misrepresentation of the human body is that only 10% of the brain is used.

Cleanliness/washing.
(Not exactly sure what a more professional term for the "step" is...)
But to wash out open wounds in the skin kills the bacteria that has already gone inside, as well as bacteria on the skin that can very easily make its way into the wound.
This also goes for internal infections, not only on the skin.
For example, drinking a lot of water, eating a lot of vitamin/nutrient/antioxidant rich foods can cleanse your blood, and help your body. It will make it stronger as well, making you less prone to infections, various diseases, and getting sick.

We eat healthful meals, exercise, maintain a clean environment (some of us have lung issues), and always talk about our mental health, and that's in my family. others have different ways but are similar if you look at the big picture and not the details. hope this helps!
