the living system me

Theories of the masterful and complex behavior and diversity of human cells attests to the living system that is me. That each cell eats, releases 'wastes' and reproduces and that each cell is attracted to and repelled by certain conditions demonstrates me as a living system. The living system that is me has cells and substances that unite to create tissues and organs and thoughts, emotions, ideas, dreams and songs. The various parts of the living system of me rely on each to all do their part to keep the whole thing going. Some of these cells may never have direct interaction with others but nonetheless their vitality and existence depend on each other.
Still, the living system of me is only part of a larger living system, which is a part of a larger living system and so on and so on...so, depends on what part of the system you stop to take a keep at. For semantics sake I get that living systems can be separate but on a grander scale, I don't think there is any separation.
