What does it mean to be human, and how human are you? As we grow from zygote to symbiote, our lives are intricately intertwined with, and deeply dependent upon, a powerful microscopic intelligence living within our own bodies. Randy Veitenheimer sheds light upon the human microbiome that influences cellular activities, bodily functions, and our behaviors to get what these microorganisms need to survive. When we learn to work in participation with our entire body, including the microbiome, we can evolve beyond our current physical and mental conditions, and make a spiritual connection with all of life.
