Final answer:
Alcohol affects memory and can cause blackouts. Chronic alcohol consumption can have long-term effects on the excretory system and organ health.
Step-by-step explanation:
Alcohol affects a person's ability to remember someone they have just met or a phone number and can cause blackouts where the person does not remember the entire event. This is because alcohol is a depressant that affects brain function, including memory. When a person consumes excessive amounts of alcohol, it can result in a complete loss of consciousness and difficulty remembering events that occurred while intoxicated. Additionally, chronic alcohol consumption can have serious long-term effects on the excretory system, liver, and kidney health.
