The self-preservation, survival instinct is the instinct of physical self-protection. As a living species, our bodies are the catalyst for our lives. It's the most basic, ubiquitous survival instinct. If our bodies fail, we cannot live. This instinct is concerned primarily with one's own physical body and its health, stability, protection, and ultimately that it continues to live.  1. Physical Well-Being The self-preservation instinct is focused on the body itself and its well-being. It includes health, strength, diet, fitness, and endurance. This facet of self-preservation is like a management system for your body. It seeks to find a root cause for problems in the body, and it can seek to test the body's endurance to harm or stress.  Possible examples of thoughts:  Is this food healthy? Why do I feel so tired today? When can I get back to the gym so I can feel more energetic? Could I climb to the top of this mountain? Could I survive in the forest for one month?
