Our bodies are continually exposed to pathogens such as bacteria and viruses that can cause illness if they gain entry into our body. The epithelial cells lining our nose, mouth, lungs and gut are sites where bacteria and viruses can enter the body. Fortunately these cells secrete molecules that activate the body’s own pathogen killing mechanisms and prevent these pathogens
The body is normally well equipped to defend itself against invading bacterial and viral infections. The first line of defense are neutrophils, cells that circulate through the blood vessels searching out pathogenic bacteria or viruses, phagocytosing (engulfing) them, then killing them with an arsenal of toxic compounds including hypochlorous acid, the antimicrobial agent commonly found in house hold bleach.

We experience an enhanced feeling of wellbeing that
In order for a rugby team like the All Blacks to be the best all the team members need to work together and be at their individual best.
