The most effective way to protect ourselves from infectious diseases or chronic degenerative diseases is to understand the concepts of proactive intervention, preventative medicine, and lifestyle support. We have a powerful, intelligent immune system that is designed to always withstand toxic microbial inundation. Medicine has evolved dramatically even compared with 20 years ago, but every new disease requires a new response. Infectious diseases can spread quickly to many patients, warns Tasuku Honjo, a Japanese physician-scientist, immunologist, and Nobel prize winner. Although normal bodily defense systems play a significant preventative role, they are not the only things needed to stop a virulent disease. We also have several white blood cells including the B-cells, T-cells, and natural killer cells, which can mount an incredible defense against any foreign invader. All these defenses are components of the immune system. The immune system is more extensive than the entire circulatory system. It includes our lymph glands and the antibodies that are transported not only by our blood circulation but also by the immune system's own lymph fluid transport system.
