I.O.W life is one of those processes which are found whenever there is an abundant flow of energy. It’s characterized by a tendency to shape or form itself as it consumes, but to do so it must always excrete low-grade products to the surroundings.  This classification of life suggests that there is a boundary between: 1) the ‘factory’ area where the flow of energy or raw materials is put to work and entropy is consequently reduced 2) the surrounding environment which receives the discarded waste products  it also suggests that life-like processes require a flux of energy above some minimal value in order to get going and keep going  For life to begin not only the quantity bu
