After one drink, a driver says that he feels more alert and confident. What does alcohol actually do to the body?
Correct answer: It is a depressant that slows the brain and nerves; the lift comes from lower inhibitions.
Why
Alcohol slows all nerve impulses and body functions, so a driver reacts later and concentrates less. The confident feeling is dangerous because it leads to risks such as speeding and passing without enough room. Only time removes alcohol from the body.
