Every living organism needs OXYGEN, including the individual cells within the organism.

Every Cell of the body has the ability to CHANGE or ADAPT to survive, when they are in danger of death.

Dr. Otto Warburg received the Nobel Prize in medicine twice for his discovery of cellular respiration and the effect that chronic lack of oxygen causes cancer.

Cellular respiration is the creation of energy in a cell through oxidation (aerobic) or fermentation (anaerobic) of glucose.

Just because your breathing oxygen doesn't mean that ALL of your cells have ALL the oxygen they need! Lack of oxygen in the cells is called hypoxia.

Everybody knows what aerobic exercise means. Aerobic exercise is exerting yourself but not to the point where you run out of breath.
When you start running you start using more oxygen, the faster you go the more oxygen you need; that creates an increased pumping of the heart to supply the increased demand. When you exert yourself beyond this point, your lungs cannot supply enough oxygen for the needs of the cells, so those cells that are lacking oxygen, in order to survive, start to create energy by fermenting glucose instead of oxidizing it. (A survival mechanism)
Your cells ALWAYS respond to their ENVIRONMENT!

When this is temporary, the cells revert to aerobic respiration once the supply of oxygen resumes; however, when this becomes chronic, cells either die or ADAPT and become cancerous. Why because ONLY A CANCER cell can live in a lower oxygen environment.

What Causes Low Oxygen environment and Cellular Hypoxia?

1) Omega fat ratio imbalance
2) Poor quality food
3) Poor breathing technique
