Answer #30 through 35 after you watch and listen to the video.What happens to your own body when you go without sleep? The brain is the control center for animals, and its purpose is to keep the body alive. There are times when the brain must act fast and respond without thought, such as in the fight-or-flight response. This automatic inborn response causes the body to "fight" or "flee" from perceived attack, harm, or threat to our survival. What fight-or-flight scenarios confronted the people in the video, and how did they react?Think of and write down another situation that could cause a person to go into fight-or-flight mode.Have you ever been in a situation where your body went into fight-or-flight mode? If so, explain the experience. If not, make up a credible one and explain it.Create a scenario that would catch a person off guard but would not necessarily cause her/him to go into fight-or-flight mode. Example: You lock your keys in your car. This is a situation that is stressful but would not cause you to react without thinking, as a fight-or-flight response would.The brain is often most active while we dream at night. It computes all the day’s activities and files them in our memory. Dreams often allow us to visit imaginative places and help us with ideas for our everyday lives.
