Sapiens Shield stops chronic disease in a population

Andrew Hague

All humans and many other species get cancer. It happens daily. The body’s cells replicate on average every six weeks. With billions of cells, some of the new cells cannot befail to be exact copies of the previous cells. The new ones are different and are mutations we callare mutations that we call cancer. Survival of the species depends on removing the wrong cells and this is done by the immune system at night during proper sleep.
