Life cannot exist without the heat that is the random movement of atoms. You know that if you put a thermometer in your mouth, you are not going to get a reading of zero. If you had no heat in your body, you would be dead. If heat is chaos, and life cannot exist without heat, then life cannot exist without chaos. You know that randomness occurs in your life at more than just the atomic level.
Heat is a form of chaos, because heat means random movement.
The chaos of heat is an essential part of life. Every day includes surprises, events that were not expected, predicted or controlled. Often, these surprises are good, or at least not bad, especially if viewed without anger at one's loss of control. In other words, if you do not insist on being in control all of the time, you can enjoy more of life's surprises. When something unpredicted happens, take it as a natural part of life on earth.
