what keeps you alive

The question seems to be about what keeps a person alive. In general, the human body stays alive through a combination of various physiological processes, including respiration, circulation, and metabolism. These processes ensure that the body receives oxygen and nutrients while removing waste products. Additionally, the body's ability to maintain homeostasis, or a stable internal environment, is crucial for survival. This includes regulating body temperature, pH levels, and fluid balance. Furthermore, the body's immune system plays a vital role in protecting against diseases and infections. Ultimately, the complex interactions of these physiological mechanisms are what keep a person alive. The search results provided information about a 2018 Canadian psychological horror film titled "What Keeps You Alive," which is not relevant to the question. Therefore, the answer is based on existing knowledge of human physiology and survival mechanisms.
