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.

The maintenance of good blood circulation is critical to ensuring we stay healthy and active. Circulation of the blood throughout

This probably occurs during this time of the year because we tend to spend more time indoors close to other people allowing the spread of viruses, and these viruses are more easily dispersed from one person to another in
Positive feelings and a sense of wellbeing are partly a consequence of the levels of compounds in our bodies called neurotransmitters. These are compounds that directly affect our brains, and the neurotransmitters that are responsible for activating positive feelings and a sense of wellbeing include compounds such as serotonin, oxytocin and dopamine. 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.
