Personality Traits. Foods and Energy. Effects of Alcohol on the Body (Тексты для перевода), страница 4

No more accurate account of the ef­fects of one or two drinks can be given because many factors determine a per­son's reactions to alcohol. The most im­portant ones are the person's weight, his metabolism, the amount of food in his stomach, and the rate at which he drinks. One person might be under the influence of alcohol after one drink. Another might not become noticeably affected until he had had three or more.

The important point to remember, however, is that even one drink af­fects the nervous system and hinders its operation. If one drink acts in this way, think of what three or four or more drinks will do!
