Finding a solution to prevent cold and flu by judging how the human body reacts such as coughing or sneezing, or blowing your nose into tissue - I realized that bacteria and viruses like to dwell in the mouth and throat area, and the best solution to get rid of these microbes is by chewing 2 pieces of gum that quickly stimulates saliva, but instead of swallowing because the ingredients can cause a mild laxative effect, you simply spit out constantly the saliva coming from the mouth and back of throat into bathroom sink, and as a result, you should have a clean and clear hygiene experience of your mouth and nose.
