Discuss the stages of consciousness including wake, interruptions of consciousness, and the stages of sleep. Summarize what a person's circadian rhythm is and provide examples of how a person can disturb the internal schedule. Include a scenario where time was adjusted significantly (or you did not have a sense of time) and how your body was affected. For example, if you got stuck in a place where there were no cues about the passage of time; you worked the nightshift for a week; you took a long flight into a different day, etc. How would you try to restore your circadian rhythm? Explain.
