It's like keeping the right tire pressure

Too much pressure under stress on your mind can cause damaging stress to your body. You can feel the squeezing ever tightening grip it has around your entire brain. As it tightens it stops the blood flow from getting to your brain. As the muscles begin to tighten in your jaw it soon squeezes causing the veins to pop out in your neck, then your torso begins to tighten squeezing every organ. Soon the pressure against your organs shuts down their ability to function under such tight restraint. Eventually your being squeezed literally to death just like you were being attacked by a giant python. Just like keeping your tires with the right amount of pressure prolongs the life of tire so to does maintaining your stress level prolong your life.
