Genes are close to immortal. No surprise they torment us with pain and ambition. We are only their shoes. You are a joint venture bissness attempted by some of the genes in the community we call the human gean pool. Entropy says energy always loses concentration and order in the long run.
Energy is like water flowing down hill.
Life is like a waterwheel that uses the energy of the falling water to pump a little water back up river, temporally snubbing entropy. This is similar to how a ball bounces. The energy is not reversed, only its direction is. Life creates complexity like a slough delays waters trip to the sea. Just as plants are like a waterwheel in the river of sun energy, animals are a waterwheel in the river of plant energy.
