ut the bloodstream and diffuses into every cell of Bob's body. This small molecule affects all organ functions, particularly the brain. When Bob's brain functions is affected by ethanol , his normal behaviour can no longer be sustained.The brain essentially is the control centre of the human body. It sends electrical or chemical signals through long strains of nerve cells, initiating proper body movements and thoughts. These nerve cells form a network throughout the entire body, similar to blood vessels and capillaries forming a network for the circulatory system. When ethanol is ingested, nerve cells' capability of transmitting rapid and accurate signals to all body parts is lost. This phenomenon is the main cause for behavioural changes in humans after alcohol consumption, and the reason why Bob was not his usual self.When the body's vital functions are threatened by an abnormally high concentration of ethanol, the body's safety mechanisms will be initiated. These mechanisms include vomiting, falling into a coma, and metabolizing of alcohol. After approximately six beers, Bob's brain says, "that's it, no more! You're killing me! Bob, I command you to vomit." If Bob ignores what his brain says to him, and continues to drink, he will fall into a coma. The brain will not tolerate Bob's excessive drinking, and will force him into a coma in order to stop him from drinking and to protect him from potential harms. These features are safety mechanisms which disallow Bob to drink himself to death. Furthermore, Bob has a properly functioning liver, which contains an enzyme capable of breaking down alcohol into harmless components of carbon dioxide and water, which will enable him to recover from his drunken state.The next morning, Bob wakes up with a bad headache. However, Bob is proud of his headache; it symbolizes of manhood. He is now a nineteen year old man who is able to consume alcohol, get drunk, and have a hangover. ...
