Alcohol can't hurt me. Alcohol won't affect my grades or activities. Those who drink get lower grades and are less likely to finish school.
Alcohol affects concentration and coordination.
This not only hurts your grades, but also keeps you from doing your best at sports, music, art, or whatever else it is that you like to do. Regular servings of beer and wine coolers contain the same amount of alcohol as a glass of wine or a 1.5 ounce shot of liquor. They all have the same effect. Alcohol makes people feel better. It can make a person moody, depressed, or angry.
