One of my guiding principles is that because our bodies are so amazingly brilliant, we should be more than happy to give them the basic things they need - whole foods, sleep, movement, sunlight, nature, relaxation. In return for this, our bodies engage in miraculous biological processes that keep us not only alive but thriving.
Did you know that we have natural killer (NK) cells patrolling our bodies? They are the first responders to threats like viruses and cancer formation. The rest of our immune system takes several days to ramp up, so NK cells are vital for keeping us healthy.
The lifecycle of an NK cell is really cool. They aren't born knowing how to fight cancer cells. They begin their lives in the bone marrow which serves as their Jedi training academy. Each day they learn how to identify and kill different types of cancer and viruses. Once their training is complete, each NK cell must pass a final test. They must demonstrate that they can tell the difference between a cancer cell and a healthy cell. This is called "licensing". Without a license to kill the NK cell cannot become a Jedi. Once an NK cell is licensed it is released from the bone marrow to serve and protect. How cool is that?
