Purely "mechanically" speaking, Live has the nature of being complementary to non-life. In investigating all this, one should try to detect, within the quantum physical formalism, still missing complementary effects, for instance "quantum dispersal", while not eleminating or devaluing the idea of quantum, modifying it in a characteristic way. The in this assumed combinatory states do not demand anything special, for the one-quantum-degrees-of-freedom may certainly also have a composed nature.
