Our cells, through epigenetics, can send signals in our bodies that will throw ON/OFF gene switches in themselves, neighboring cells, distant cells. Neighboring cells can communicate via direct connect with each other like a handshake. Nearby cells can communicate by passing signals back and forth like throwing a ball in a game of catch. Some signals. Like stress, send out broadcasts like a radio or TV signal. These broadcasts affect large number of cells throughout the body. Stress signals the body to prepare for an event. Different cells do different things to prepare. The signal stops and things return to normal when the stressful event ends. Modern life can cause us to be in a stressful state constantly.
