In physics marriage

     In physics, the law of entropy says that all systems, left unattended, will run down. Unless new energy is pumped in, the organism will disintegrate. Entropy is at work in many areas other than physics. I see it, for instance, when I work with couples whose marriages are in trouble. A marriage will not continue to be good simply because two people love each other, are compatible, and get off to a fine start. To the contrary, marriages left to their own devices tend to wear out, break down, and ultimately disintegrate. This is the law of entropy. So to keep our relationships working, we must constantly pump new energy into them.—Alan Loy McGinnis*[1]
