How to be Immune To Diseases [EPUB ebook] 
Practical guide to strengthening the body.

Your IMMUNE SYSTEM is an incredible machine. It is responsible for KEEPING your body PROTECTED from external invaders, such as viruses, bacteria, fungi, and toxins. Your immune system comprises two main parts: the part you were born with (innate or non-specific system) and the part you DEVELOP from your exposure to the environment (acquired adaptive system or specific system). Your immune system is MADE UP of several organs, cells, and proteins – skin cells, blood, bone marrow, tissues, and organs such as the thymus and lymph nodes. A STRONG immune system is the best DEFENSE against illnesses and infections. Without it, you have no way to fight harmful substances or changes that occur in the body. Good reading!
